The development of "electric vehicles", one of the hottest topics in 2021, has become the growth engine of the automobile industry in recent years, accelerating the transformation of the automobile industry. According to Market Intelligence & Consulting Institute (MIC), by 2030, the cumulative number of electric vehicles in the world will grow from 11 million in 2020 to 230 million. Moreover, the world pays more and more attention to the issues of circular economy, carbon neutrality, and green supply chain transformation, which also drives the automobile industry's requirements for "lightweight", and makes automotive plastics and injection molding machines with two-plate structure face more business opportunities. FCS Two-Platen Injection Molding Machine (LM Series)
integrates European technology, which enables customers to save plant area, produce larger or deep cylinder products, and reduce energy consumption by 50%-70%.
In addition to providing stable and high-quality equipment, FCS also offers another important added value, that is, "professional customization capability".
One of FCS’s customers in the auto parts industry in the United States is the Tier 1 supplier of well-known car manufactures, processing auto parts for Ford, Toyota, and GM. This year, the two-platen injection molding machine (LA-1210) purchased from FCS is used to produce the car grills. Due to the insufficient height of the factory building, the customer's mold cannot be lifted vertically from above the machine and installed between the two platens for mold clamping as normal process. Therefore, FCS was required to customize the "Tie bar puller function" of the machine, so that, if necessary, a tie bar can be drawn out and the mold can be installed horizontally from the side of the machine.
This is the first successful case of "tie bar puller" sold by FCS to the United States. The customer has a high opinion of the machine and expects to purchase another LA two-platen injection molding machine in the next year. In addition to the LA series, the customer also purchased a new generation of FCS Advanced Servo Hydraulic Injection Molding Machine (FA series)
for the manufacturing of car fasteners.
Due to the design of the machine structure, the "tie bar puller function" in the injection molding machine is only used by the two-platen injection molding machine. FCS two-platen injection molding machine (LM/LA Series) of full tonnage can customize tie bar puller, and the range of clamping force can reach 500-4000 tons. At present, after this customized machine was first exported to Germany in 2020, FCS continues to expand its business map. At present, it has successfully traded five the two-platen injection molding machines with tie bar puller function and sold them to Asia, Europe and America.
As of this year, FCS’s customers which have requested to customize the tie bar puller function are engaged in automobile and bicycle accessories, household hardware
, PVC plastic pipe fittings
, and bottled water
. In the future, it is hoped that the technology may solve production problems for more customers and effectively meet customer needs.

"Tie bar puller" related FAQ:
1. What needs/difficulties do customers have when they require the "tie bar puller function" of the injection molding machine during production?
◼ The height of the factory building is insufficient
The most common situation for customers is that the height of the factory building is limited, and it is impossible to hang the mold directly above the machine with the crown block and enter the mold platen for fixation.
◼ The mold width or total configuration width is larger than the existing tie bar inner distance
When the mold width is larger than the existing inner distance, the mold needs to turn in high altitude to meet the tie bar inner distance when lifting the mold vertically above the machine for installation. Hence, some customers ask to pull out a tie bar and install it transversely from the side of the machine.
◼ Other factors
When the tonnage of the machine is large, the weight of the mold is heavy. Based on the safety consideration, the height of the mold hung by the crown block is limited to reduce the danger of operating the crown block.
2. Technical requirements/overall structural design of the tie bar puller
At present, the design is to pull away the tie bar above the operating side behind the fixed platen, so as to assist the cylinder to drive the whole tie bar and pull away. The core requirements include linear guide selection and fixture selection calculation, cylinder specification calculation, and mechanism planning for bearing deformation range.
3. The tie bar puller is accompanied by possible bending deformation. How does FCS overcome the problem?
In order to shorten the withdrawal stroke and reduce the dead weight of the tie bar, the tie bar is shortened without affecting the maximum mold thickness and mold clamping to reduce the deformation caused by the dead weight. The tie bar to be pulled out is held by a copper sleeve in the fixed platen in order to stabilize the tie bar after pulling out and reduce the deformation, to prevent the inaccurate positioning during mold clamping due to excessive deformation.
