What is a gas-assisted injection molding system
Written by Jasmine HL
Gas-assisted injection molding system, this advanced system, and technology is a plastic wrap
that injects nitrogen directly into the mold cavity through a segmented pressure control system.
No shortage of.
The application of gas-assisted injection molding technology has the following advantages:
1) Saving plastic raw materials, the saving rate can be as high as 50%.
2) Reduce product production cycle time.
3) Reduce the clamping pressure of the injection molding machine, which can be as high as 60%.
4) Improve the working life of the injection molding machine.
5) Reduce the pressure in the cavity, reduce the loss of the mold and increase the working life of
the mold.
6) For some plastic products, the aluminum mold can be used for the mold.
7) Reduce the internal stress of the product.
8) Solve and eliminate the problem of shrinkage on the product surface.
9) Simplify tedious product design.
10) Reduce the power consumption of the injection molding machine.
11) Reduce investment costs for injection molding machines and mold development.
12) Reduce production costs.
Gas-assisted injection molding technology can be applied to various plastic products, such as
television or audio enclosures, automotive plastic products, furniture, bathrooms, cabinets,
home appliances and daily necessities, various types of plastic boxes and toys, and so on.
Gas-assisted injection molding technology must be widely used in the injection molding industry.

Basically all thermoplastics (reinforced or unreinforced) used for injection molding, and general
engineering plastics are suitable for gas-assisted injection molding.
Computer-aided simulation analysis
1) Prevent trapped air and ensure even gas filling.
2) Prevent the gas from breaking the surface of the finished product.
3) The trapped gas has extrusion characteristics and plays a certain important role in the holding
pressure stage. Therefore, the use of computer-aided simulation analysis can ensure a more
accurate prediction of plastic distribution and mold filling.
System requirements for injection molding machine
Basically, gas-assisted injection molding systems can be used with different brands of injection
molding machines worldwide, as long as these injection molding machines are equipped with:
1) Slingshot nozzle to prevent high-pressure gas from running into the screw of the injection
molding machine.
2) The screw stroke of the injection molding machine is equipped with an electronic ruler stroke
switch to trigger the signal to the gas auxiliary main system to inject high-pressure nitrogen into
the mold cavity.
