Not Powder Injection Molding Process, PC Used in Plastic Injection Molding

Though both MIM and plastic injection molding are injection process, but their materials are completely different. Now let’s see the characters for PC used in plastic injection.

Characters for PC in plastic injection molding can be conclude as follows:

1. Has a prominent impact toughness and creep properties, has high heat resistance, cold resistance is very good also, brittle temperature - 100 ℃, the  tensile strength is equal to  nylon. PC has much higher elongation and elastic modulus as well as prominent impact strength. Colorless, transparent, good coloring, better heat resistant than  nylon and methanal. Creep resistance and good electrical insulation, good corrosion resistance and abrasion resistance; low water absorption, small shrinkage, good stability.  PC can be used for all kinds of gear, turbine, rack, CAM shaft, pulley, bearings, core, transmission chain, nuts, washers, pump impeller, chimney, container, etc

2. Not alkali resistance, amine and arene. It maybe craze by stress, easy to produce stress concentration (and internal stress), and highe requirements of molding conditions.  Easy to hydrolysis in high temperature,  poor compatibility with other resins.; Poor liquidity, sensitive to temperature change, fast cooling.

3. Cylinder temperature is very important to control the quality of plastic parts. Low temperature will cause starving and matt surface; occur silver and  filaments at high temperature.

4. In case of polycarbonate material contains water, it will seriously affect the flow of the material performance. Therefore it must be dried, commonly at 110 ~ 110 ℃ temperature for 6 ~ 15 h.
