PC parts injection technology is good or not which play a important role in PC parts production, so we pay more attention to PC parts injection notice, especially in injection machine selection, injection moulds design points.
The injected PC parts are with high transparency, high gloss, and widely used in electric cover parts and inner structural parts. Below are the PC parts injection notice.
PC parts injection specification:
Before injection, the PC material needs to be dried for at least 4 hours. Pure PC drying temperature is 120℃,and for modified PC, is110℃. All PC materials can be dried more than 10 hours.
PC parts mould design point:
PC parts mould temperature is about 80℃ to 100 ℃, if adding glass fiber, the temperature is about 100℃ to 130 ℃. Like some small products, the pin gate can be used, and the gate depth needs to be 70% of most thick position. The flowability of PC is not good, so the gate is bigger, will be better, and the runner should be short and round, venting slot should be 0.03-0.06mm, the demoulding angel be about 30′-1.
Injection machine suggestion for PC parts injection:
Now PC products, due to cost and other reasons, almost use the multi-purpose modified materials, especially the electric products, still must increase the fireproof performance, by the flame retardant. In the PC injection molding, the requirement for injection molding machine of plasticizing system are well mixed, corrosion resistance, the conventional plasticizing screws hard is meet the demands, when the choose and buy the injection molding machine, be sure to explain in advance. Dakumar Machiney has a dedicated PC screw for the customer to choose.
