                                         Gas Assisted Injection Molding Machine

Gas assisted injection molding machine is one kind of advanced cable manufacturing technique; its working process is as follows:

Firstly, inject hot melt plastic PE into the plastic-sheathed cavity outside the copper wire of cable, then adopts accurate automatic control system to inject high pressure N2/CO2 gas into molten plastic, making inside of plastic part expand and become hollow, gas evenly distributed throughout the plastic.

After injection ends, he cable will have excellent signal transmission characteristic after cable cooling.

Shineeast provides gas assisted injection molding machine with stable performance for high pressure physical foaming cable production line, with its outstanding gas pressurizing and control technology.
