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.

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 2004, 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).

 The all electric injection molding machine adopts electrical components to drive the IMM, which avoids leakage of hydraulic oil, pollution from waste oil, operation noise, and achieves more power-saving. The Europe's Association for plastics and rubber machinery manufacturers (EUROMAP) announced the guidelines of “Euromap 60” for addressing the crucial matter of energy efficiency.All electric IMM possess advantages of precision, stability, cleanliness and power-saving that is widely applicable for injection market.

 PR Newswire indicates the global automotive plastics continually growing which is expected to achieve 19.68 billion US dollars and compound annual growth rate up to 2.9% by 2023, the main demand sharp grow from automotive components, packaging, medical appliance and consumer goods. Moreover, FCS All Electric IMM is capable to connect iMF4.0 to help attain the concept of unmanned smart factory.

"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 2004 to develop AF Series high speed hybrid injection unit and CT Series all electric in 2017. 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.
