Información del producto

Generally, customers in injection molding industries for years are equipped to judge and select by themselves suitable injection molding machines that fits them. But under certain circumstances, customers may need the assistance of the manufacturer to decide which specifications will meet their needs. Sometimes, they may ask if the machines of the manufacturer could produce the products they have in mind, which they merely have a concept or sample, or they would ask which model is suitable. Also, some of the products may need special devices, such as accumulator, close loop, injection compression to match with the selected unit to manufacture their products efficiently. Hence, it is of vital importance in determining what type / model of machine will serve their needs best. The following are information for your reference in making a decision.

Generally, the main factors that affects the selection of injection molding machine include: molds, products, plastic material, molding requirement, etc. Therefore, before proceeding with the selection, the following information must be collected first:
1.Mold size (width, height, thickness), weight and special design.
2.Type and quantity of plastic materials to be used (single or multiple materials).
3.The outer dimensions of the products (length, width, height and thickness) and their weight.
4.Molding requirements, such as quality, manufacturing speed, etc.After obtaining the above information, follow the following steps to select a suitable injection molding machine:
1.Select the right model: Decide the type and series of machine base on the products and the plastic materials.
2.Accommodate: Based on the dimensions of mold, determine whether the distance between tie bar, mold thickness, min. mold dimension, and mold plate dimensions are suitable or not, to confirm that the machine can accommodate the mold.
3.Retrievable: Based on the mold and product, determine whether the Mold Opening Stroke and Ejecting Stroke allow the product to be retrieved.
4.Lockable: Determine the mold locking force based on the product and plastic material.
5.Sufficient Injection: Determine the volume of injection from the weight of products and number of mold caves, and select suitable screw diameter.
6.Good injection: Determine the “screw compression ratio” and “injection pressure” from the plastic materials.
7.Fast injection: Checking the injection rate and injection speed.

For other details, please refer to the file "How to select suitable injection molding machine" under the category Technical Documents", in the Download section of this website.

There are many criteria for categorization of injection molding machines, but it can generally be separated into the following types:
1.In driving manner: hydraulic, all electrical, hybrid type injection molding machine.
2.In opening and closing direction of mold clamping unit: horizontal, vertical. Most of the machines are horizontal type. Vertical type is suitable for small insertion products.
3.In material processed: thermoplastic material, thermosetting material (thermosetting), powder injection (metal, ceramic, alloy). Presently, most of the units are for thermoplastic materials.
4.In hydraulic loop: single loop, multiple loop (dual or triple) injection machines. Most of the units presently are single loop injection molding machines.
5.In hydraulic circuit control: open loop, close loop injection machines. Injection molding machines are generally of open loop type, but the close loop type is growing for machine stability.
6.In mold clamping structure: toggle type, hydraulic, hydra-mech (two-plate type). In these 3 types, each has its own advantages and shortcomings. Presently toggle type is prevailing.
7.In injection mechanism: single color (one set injection), multi-color (multi-component injection). Most of the existing units are single color units.

In single hydraulic circuit, injection molding machine motions is under one hydraulic force guidance, all mechanical motion acts in sequence. Generally, the motion sequence of injection molding is as the following:
1.Mold closing: close the male mold to the female direction to be locked status.
2.Carriage forward: move and fit the injection nozzle to the feeding port of mold.
3.Charging: through the rotation of screw, the granular material is fed into material pipe for heating to molten type.
4.Injection: inject material into mold cavity.
5.Pressure holding: keeping injection pressure to prevent material reverse flowing and shrinking of product.
6.Front suck: screw retreat a certain distance for further feeding.
7.Charging: through the rotation of screw, granular material is fed into material pipe for heating to molten type.
8.Back suck: after feeding, screw retreat a distance.
9.Cooling: Waiting for cooling and solidification of product.
10.Mold opening: separating female and male molds.
11.Ejecting: eject product from mold.
12.Again mold closing, injection, pressure holding, suck, and the cycle continues.
In the above process flow, pressure holding and front and back suck are not always exist, which depends on molding conditions. Hence the process flow of injection molding can be simplified as: mold closing, injection, feeding, cooling, mold opening, ejecting, mold closing and so on.

In general, an injection molding machine is a piece of high pressure, high speed, and partially high temperature machine. For the dangerous areas, please refer to the sketch below.
1.Charging area: Screw is rotating here, do not place iron bar or any foreign matter into this area.
2.Barrel cover area: This is material heating area, with extremely high temperature and has the possible of electric shock.
3.Nozzle area: Material is injected in high pressure in this area. There is the danger of splash.
4.Mold area: This is the high speed and high-pressure closing and opening area, very dangerous. Also, the material could be jetted off from the mold. Special care shall be given in this area.
5.Ejecting area: Need special care as powerful mechanical motion is occurring here.
6.Mold clamping mechanism: Need special care as high speed and powerful motion is occurring here.

1. Injection Unit
In addition to basic metal plate guard, there is injection safety cover at the nozzle area for preventing splash of material. Injection unit will not be able to act without the cover in position.
2. Clamping Unit
In addition to basic metal plate cover and front and rear safety door, there are mechanical, hydraulic and electrical safety devices. When the machine is in operation, all these safety device would be activated, if one of the safety door is opened, and the clamping unit will stop moving.
a) Mechanical device: Generally, there is a safety lever on the movable mold platen. At emergency (one of the safety doors being opened) with the mechanical blocking or grabbing, the clamping mechanism will be stopped forcefully.
b) Hydraulic device: To offer further protection, when one of the front and rear safety door is opened, the relief valve will exhaust pressure in the system, and the clamping element will become inactive.
c) Electrical device: To prevent the failure of relief valve, when one of the front and rear door is open, the 2 limit switches on the safety door will have no signal of door closing and open signal is available, then the clamping element will be inactive.
3. Emergency Stop Switch
A red “Emergency Stop” press button is installed to each of the front and rear operation cabinet. When one of them is pressed, electrical motor and pump will cease operation immediately (but the power is still on), the machine will not be able to operate. Before operation of the machine, validity of these two buttons must be tested. If any one is invalid, complete check must be done to be safe.

1. All Electric Injection Molding Machine is not very different from hydraulic injection molding machine in body mechanism, but in the uses of AC Servo Motor, Ball screw, Gear and Timing belt to substitute the original hydraulic element, such as hydraulic motor, directional valve, hydraulic board and cylinder). Since electric elements are used to drive the injection machine, it is therefore called “ All- Electric”, and because the hydraulic element is replaced, there is not problem in hydraulic oil leakage and pollution, so is the operation noise. There are savings in energy and electric power consumption is lower. It is of higher accuracy than ordinary hydraulic injection molding machine.

2. Despite the advantages in energy saving, highly clean, low noise, All Electric Type Injection Molding Machine has certain shorts needs be improved. The problems include: high cost of servo motor, the durability of ball screw, difficulty in developing large tonnage clamping force model, and in area with instable power supply, it is unable to use accumulator to create transient high pressure. Among them, cost is t he main reason that the all electric unable to totally replace hydraulic type.

1966, Battenfeld of Germany pioneered the electric mechanism injection molding machine with electric motor feeding injection molding machine. However, not until Fanuc, Japan, with its own electric servo control technical advantage, cooperate with Milacron and commercialize all electric injection molding machine in 1994 had this type machine commence to prevail. In the Dusseldorf Exhibition (K’ Show) 2001, European firms had also presented all electric injection molding machine. In fact, since the introduction of commercialized electrical type injection molding machine, all electric type has been based in Japan and North America markets. Many European firms are not keen in the development, but following the endeavor of Japanese firms and the market situation, the European firms could not stay at sideline, they finally introduced their new generation all-electric injection molding machine, such as Battenfeld、NETSTAL、ENGEL、MIR、OIMA、NEGRI BOSSI. With the development of major players of Europe, USA and Japan, incorporating all electric unit into production line is a trend destined. What worth to note is that in recent years, some of the European and American firms introduced hybrid injection molding machine, or electrical injection molding machine, then all electric. Examples are Husky of Canada, Arburg of Germany, Demag, Krauss-Maffei, Sandretto of Italy , even JSW, Sodick, Toshiba and Meiki of Japan are all introducing their hybrid or partial electrification of injection molding machine. Either all-electric or hybrid type, they are within the scope of electrification. Therefore, there is wide discussion over whether the development of injection molding machine will be fully electrified or partially (hybrid).

"Hybrid Injection Molding Machine", as the name tells, is combining hydraulic and electrical mechanism into injection molding machine. It has the precise positioning and energy saving feature of all electric, and on the other hand, it maintains t he high push of hydraulic mechanism. In other words, the hybrid unit, with lower cost than all electric, is able to improve the energy consuming and less precise problems of conventional hydraulic units, and it can greatly reduce contamination and noise. In fact, reading from statistics, 45% of European/ American/ Japanese manufacturers are providing hybrid units, and about 20% of them are offering both all electric and hybrid units. This means, in future, there will be more and more manufacturers incorporate all-electric and hybrid units into their production line, and this will offer high flexibility for molding operators in selection of types and models.

Between the 2001 K’ show European and American participants, though 7 of them have all electric, but still 9 are providing hybrid units. It seems that they prefer partial electrification than all electrification, particularly incorporating electric servo motor driving design into feeding system is popular in the injection molding machine manufacturers of Germany and Italy. The German Plastic Magazine-- Kunststoffe Plast Europe—reported in their Dec. 2000 issue that DELPHI has forecast the global injection machine market will be shared by 3 types, 34% hydraulic, 28% all electric and 38% hybrid, with hybrid takes the lead, which worth to think over. As reported there, all electric units do have advantages in small clamping force models, but the advantages are not fit to all plastic products. The energy saving and low contamination characteristics are more suitable for products need high cleanness, such as medical and food containers, and the high electricity rate area. The high performance hydraulic and hybrid units will still have their market stands.

In view of this, Fu Chun Shin, in addition to improve the original hydraulic injection molding machine and introduce brand new HT Series, has gone further in 2001 to develop AE Series hybrid high speed injection unit and HB Series hybrid high speed two component unit. FCS has also cooperated with ITRI in developing HE Series all electric. It is one of few manufacturers who can offer hydraulic, all electric and hybrid injection molding machines. Customers can select the most suitable units from our product lines based on their need and investment costs.

Normally an injection molding machine has 6 important moving axis, which are injection, feeding, carriage forward and back, mold closing and opening, mold adjustment and ejection (core and unscrew). Majority of hybrid units maintain carriage forward / back, ejection, core and unscrew in hydraulic driven mechanism, and change the injection, feeding, mold closing/ opening and mold adjustment to be electrical driving mechanism. But if high speed injection function is required, it basically needs to remain injection element at hydraulic mechanism and adds accumulator and close circuit control to have transient high speed injection. We can see that which parts shall be maintain at hydraulic driven will mostly depend on the requirements from products, key molding function and the building cost of the machine. The purpose is to find an optimum balance among machine performance, quality and cost t o spend.

Injection compression molding can increase the molding accuracy, saving energy and reduce production cost, and the purpose is to reduce the injection and holding pressure at molding, and to reduce the distortion of product and internal residual stress. Injection
compression can upgrade the product quality and evenly promote the product density,
allowing easier molding of thin and large pieces. (For other detail, please click” Introduction of Injection Compression Molding Techniques” file at the Technical Documents of Information Downloading area of this website).

Injection compression molding has certain requirement on accuracy of metering, mold platen parallel, compression speed, compression starting time and compression force. (For other detail, please click” Introduction of Injection Compression Molding Techniques” file at the Technical Documents of Information Downloading area of this website.)

Bi-injection is generally refer to the molding of two color or two type of resin. Since in Bi-injection, there are two independent injection elements and nozzles, the color of product is normally clear-cut in color, without mixing together. On the other hand, the interval Injection uses compound nozzle to join the resin from two sets of injection element and match with the injection speed, pressure and time changes to cause the color to mix, to fade from one to other or to generate prints on product. As to Sandwich injection, it uses compound nozzle to join the two type of resin, but there shall have special design that one of the material is sandwiching the other to form core material and skin material. So, unless t he product is cut sectional, it is normally unable to see the core material but the skin material.

Bi-injection unit is different from general injection molding machine mainly in the injection element and movable mold plate design. Generally, Bi-injection has two independent injection elements, but only one with general injection unit. The deployment of two injection element has various type different from designs of one to another manufacture, such as horizontal parallel, horizontal Y uni-direction, horizontal L type, Vertical L and vertical Y, even in horizontal parallel contra-direction arrangement for two plats clamping structure. As to movable mold plate design, it has to have rotating mechanism. Frequently seen designs include rotary table or rotary axis mechanism to provide 180 deg. Reciprocal rotating function to allow cycling alternate motion. Still other special Bi-injection units do not need rotary table or rotary axis mechanism, but for the mold to provide the alternate or horizontal rotation.

Interval injection and sandwich injection are almost same general injection molding unit, and the only difference is the interval injection and sandwich injection unit both has two set injection elements injecting material into molds from common nozzle, and the difference between interval injection and sandwich injection is in the design of compound nozzle.

GAIM is injecting nitrogen into mold cavity during injection molding process and using the nitrogen to perform pressure holding , making hollow products to reduce weight and prevent retraction sinking, and cut down pressure required. It is also call Nitrogen Hallow Injection Molding or Lowe Pressure Hollow Injection Molding. But it is different from Blow Molding.

GAIM is basically including the following 4 steps:
1. Injecting fixed quantity of material into mold.
2. Injection nitrogen to hollowing product to reduce weight and assist the fluidity of material.
3. Nitrogen pressure holding: As the material is cooling and retracting, the nitrogen will undergo secondary penetration and prevent the product from sinking or spring-back.
4. Release of high pressure nitrogen: releasing nitrogen in the mold cavity.

1. For bulky / thick products
a. Saving material, reduce weight by 20~50%.
b. Shortening molding cycle(reducing cooling time)to 20%.
c. Reduction of mold cost.
d. Saving in post-processing.
2. For flat products
a. Increase in design varieties.
b. Appearance improvement and better electroplating effects.
c. Eliminating thick rib sinking of products.
d. Realizing low pressure molding and reducing clamping force.
e. Less residual stress in product and reduce the distortion and deformation.
f. Increase the structural rigidity of products.
g. Reduce number of parts.

It needs 98% purity nitrogen or higher, because nitrogen is easily available, low prices and will not react with the material. The oxygen in high air may mix and combust with molten resin, so the later is rather not suitable.

It needs 98% purity nitrogen or higher, because nitrogen is easily available, low prices and will not react with the material. The oxygen in high air may mix and combust with molten resin, so the later is rather not suitable.

The following equipment are required to apply GAIM techniques.
1. Injection molding machine.
2. Gas Assisted Injection equipment.
3. Nitrogen Generator or Nitrogen Cylinder.
4. Air Compressor.
5. Necessary molding peripherals.

Techniques involved with GAIM include mold design, product design, gas pin location
design and analysis, gas assisting device techniques, injection molding techniques, solution for defective molded product and mold flow analysis.

Not necessary, GAIM system of Fu Chun Shin can match with other brands of injection molding machine.

In addition to providing GAIM equipment, we also provide training on GAIM techniques, mold flow CAE analysis, product structure design, practice instruction and turn-key technical services packaged with injection molding machine.

1. Entering from nozzle:
Benefit
a.  Can readily use with modification to existing mold
b.  Runner is in hollow shape, reduce the quantity of resin
c.  Product free of needle trace
Short
a. All air path must be connected
b. Air paths must be symmetric and balanced
c. Cannot be used in hot runner system
d. Nozzle of machine must be replaced at high cost.
2. Entering through mold:
Benefit
a. Can enter through multi-point, and the air paths need not be totally connected
b. Gas and resin can be injected in at same time
c. Hot runner design mold permitted
d. Can be used in asymmetric mold cavity molding
Shorts
a. Need to develop and design new mold
b. Leaving needle trace on the product

In actual application, there are lots of examples that applying GAIM
techniques improved the surface sink mark and distortion caused by
existing mold; however, the design concept is totally different from the
conventional injection molding, it takes redesign of air path to
improve the molding quality.

It can reduce the need for higher clamping force, but need to have enough large column inner distance and injection volume.

It can reduce the residual stress in product, and can prevent the retraction distortion.

Shortening molding time and reducing weight are the main reason for
heavy, thick piece adopting GAIM, but the length of molding cycle is
still subject to the cooling time of the thickest part of product after
hollowing.

CAIM can eliminate chamfering and coring mechanism and reduce material of mold ( with low
pressure molding) but will increase air needle, mold modification and mold testing cost.

GASCIM unit uses high pressure nitrogen generated from special gas device to precisely control gas pressure, flow, time to inject the gas into molten resin in sandwiched co-injection mold and complete gas assisted sandwich co-Injection molding. In other words, GASCIM is processing equipment combines gas-assisted Iijection molding and sandwich co-injection molding. The functions included are the benefits of both parents, and the application can expand to thin-wall 3C for increasing mold prosperity, reducing distortion and deformation, promote product yield, reduce cost and increase functions of product and quality.

PET is polyethylene terephthalate, a saturated polyester co-polymerized with terephthalate and Ethylene Glycol. It is good in transparency, gloss and airtight, and it meets the Food Safety Standard, and it can be recycled for re-use. The glass transfer temperature (Tg) of PET is between 75~80℃, and injection molding temperature is between 270~310℃, the mold temperature is 130~150℃. Since PET is high in water absorption, humidity prevention is specially required in storage, and before processing, it has to be dehumidified and dried under 150~180℃ for 4 hours normally. And, in order to prevent the resin to re-absorb moisture, it shall be kept at temperature above 140℃.  When operation is stopped, to prevent the resin turning yellowish, the dehumidifier / dryer temperature needs be drop to 100℃, only maintaining the temperature but not humidity. At the injection molding, if the material temperature is too high, screw shearing force is too high or revolving too fast, it is likely to generate acetaldehyde and leading to caudation. Normally, the molded PET bottle shall contain less than 3ppm of acetaldehyde.

In general, PET preform molding methods are in two types: direct blowing molding and extended blowing molding.
1. Direct blowing molding: This is to inject molten PET bottle on same machine (normally referred to as Injection Stretch Blow Molding, then in the hollow mold blow and stretch to molded product. Since the PET bottle is molded and stretch blown on same unit, so it is also called one step method, and before the bottle cooling off, the bottle is blown with the remaining heat, so it is also called Hot Bottle Blank method.
2. Stretch blowing molding: In this method, injection machine is employed to produce the bottle, then the cooled bottle is heated on stretch blown unit, and stretch and blow in hollow bottle to mold. Since this method is processing on injection and stretch blow machine, it is also called 2-Step method. Also, this method heats cooled bottle to blow and stretch, it is also called Cold bottle method. The process flow is as the following: dehumidify and dry PET materialinjection machine melt material and inject into moldcool PET bottle to molddual axis stretch blow molding by Stretch Blow Molding. Note: The dual-axis stretch is stretch longitudinally with stretching rod and high- pressure air for laterally extension.
3. The application: Generally, one-step method is better suitable for small volume production for large number of specifications. 2-step method is suitable for mass production of limited type. Our FT-P series—PET preform injection molding special unit is of 2-step method.

PET material has been widely used in the packing container for the following products: water bottle, juice bottle, edible oil bottle, cosmetics bottle, drug bottle, bear bottle, wide neck bottle, detergent bottle.

1.Hydraulic Oil: Check if the hydraulic oil is between min. and max. line of oil gauge? If the
toggle auto filler oil at proper level?
2. Cooling water: Check if the cooling water pipe is free of leakage and if water level sufficient
to have normal cooling effect.
3. Start heating element and check: Ensure the electric heater of dryer, barrel and mold are at normal condition, especially the temperature must reach the set temperature before working injection, retreat and screwing motions.
4. Check the safety door and safety rod: Ensure the opening and closing of safety doors are normal, and the contact between safety door and each limit switch and the pressure relief valve are normal. Ensure the safety rod is proper position and firmly locked. Ensure the red press buttons on the operation box are working normally, so as to ensure the safety of operator.
5. Lubricating device check: Check if the grease oil level is sufficient and the filler time setting is proper and the filing device piping are unimpeded?
6. Moving mechanism check: All moving mechanism shall have proper lubrication, and the debris and dust on the moving parts shall be cleaned and maintain the friction surface clean and smooth. No tool shall be placed on moving parts, so to avoid breaking while machine                 is in operation.
7. Low pressure mold closing device check: Correctly adjust low pressure mold closing device to ensure the safety of mold.
8. Check other conditions: Ensure all settings, such as temperature, pressure, speed, timing and distance are correct.
9. Load free check: Work full-auto operation at lower pressure and let it run load-free for 10 to
30 min. and commence normal operation after a steady working condition is reached.
10. Noise check: Record the sounds at normal operation and the sound of hydraulic pump, it will allow operator to detect abnormality like blocking of filter, air-intake, internal wear. The buzz sound of solenoid is related to the debris in the internal axis. The buzz sound of      relay and magnetic contact indicate dirt and dust existence at the contact. Check the cause of the noise will be helpful in preventing damage.

1. Shut the gate of material hopper and reduce or close the heating device of hopper (depends on
the length of time of the stop.
2. Shoot out all the resin in the material pipe, particularly acid and corrosive materials must be    totally cleaned up.
3. Wipe mold to clean and apply anti-rust treatment. (depend on the length of time stopping operation)
4. When machine stopped, if the mold is not removed, do not extend toggle straight.
5. Close cooling water and switch off power.
6.Clean machine.

Weekly regular check
1. Heater check—Check for any broken wire or ill contact.  (For CE model, check the reading of amp meter).
2. Leakage check—Check the fittings of cylinder, oil pipe and solenoid for leakage.
3. Screw and nut check—Check the bolts, screws and nuts of the whole machine for any loss or loose.
4. Nozzle heater band check—remove any and all material attached to the lead wire and nozzle heater band.
5. Remove deposited waste oil on the machine.
6. Filtering mesh cleaning- within the first month, clean it every week, thereafter on monthly basis. Clean the whole machine.
Monthly regular check
1. Perform stricter check as per the weekly items and in determined manner.
2. Grounded wire check: grounded wire shall be checked strictly to ensure the user would not suffer electric shock.
3. Electric wire check: Electrical parts are likely to loose off due to vibration, burnt due to increase in current. So the terminal screws must be fasten firmly, and the dust, foreign matters and oxidation on the contact must be removed.
4. Movable mold platen and hydraulic motor seat skate check: check if the skate worn out, screw loose and moving parts are lubricated.
5. Cleaning and check of cooler: if underground, industrial water or salt water is used, remove the cooler to clean on monthly basis to improve and extend the efficiency and service life of cooler. If ordinary tap water is used, it may be cleaned in six-month interval (Basically, soft water is preferred, and add soften agent and scaling agent.)
Six-Month regular check
1. Repeat the monthly items in stricter and firmer attitude.
2. Hydraulic oil regular check: ask the oil supplier to make regular check of hydraulic oil to ensure the quality of hydraulic oil.
3. Check for any abnormal wearing of the moving part of machine.
Annual regular check
1. Repeat the half-year items in stricter and firmer attitude.
2. Electric motor check: Clean the intake port of cooling portion of electric motor with steel brush or air blower, because any dirt or dust exists, it will cause the motor to heat up and result to other heat damage directly.
3. Ventilation system check: Ventilation window installed on closed machine is for ventilation, so the oil stain and dirt attached shall be cleaned to prevent damage due to heating or cause oil temperature to rise.
4. Insulation check: The insulation of wire cover is downgrading gradually, so it is necessary to perform insulation measure to avoid accidental electric leakage and identifying earlier will permit prevention.

El corredor también se llama corredor horizontal y es el canal para moldear el material desde el bebedero hasta el molde hembra. El corredor normalmente necesita solidificarse antes de sacarlo, por lo que el corredor se corta en dos mitades en la línea de diámetro para procesarlo y luego emparejarlo. En base a la fluidez, forma de sección del corredor, hay forma redonda, U, trapezoidal, rectangular y cuadrada. Ronda, semiesfera y trapezoide son las mejores. Pero en la fluidez y disipación de calor, el corredor redondo es el mejor. Los siguientes son rectangulares, trapezoidales y cuadrados. La semiesfera se usa bastante menos, excepto en circunstancias especiales. Los beneficios y los cortos son los siguientes.
