Gas Assiated Injection Moulding has improved the quality and save cost owing to the principle of gas assisted injection moulding.Gas assisted moulding has developed rapidly in recent years,gas assisted mould manufacturers try their efforts to manufacture better gas assisted mould to gain the market.
Gas assisted injection moulding is a emerging injection moulding technology,it realized by injecting high pressure insert gas when the plastic has filled the cavity about 90% to 99%,then the gas push molten plastic to fill the full cavity,make use of the gas pressure to replace plastic pressure.
The gas assisted injection moulding process has 4 steps.
Step 1: Plasic injecting.Inject molten plastic into cavity,form a layer of solidification when come to the cavity with low temperature.
Step 2: Gas injecting.Inject high pressure insert gas into the molten plastic,push the plastic go on filling the whole cavity.
Step 3: Pressure maintaining by gas.Under the state of pressure maintaining,the gas put pressure on molten plastic to assure the outlook of products.
Step 4: Gas emptying. When the gas is empty,the gas will turn to ordinary pressure,then the products can be pick out.
Gas assisted injection moulding is applied in the fields of car,color TV,plane and some goods used in daily life.SinoMould,a big gas assisted moulding manufacturer,is skilled in manufacturing this kind of mould.Welcome to contact us if you want to know more about gas assisted injection moulding.
