How to injection molding a perfect PC+gf transparent plastic parts?

Transparent plastic PC + gf products because want to high light transmittance, so of course demands PC + gf surface quality of plastic products is too strict, can not have any markings, porosity, white fog, dizzy, defects such as poor black spots, color and luster, thus in the whole process of raw materials, equipment, tooling, injection molding and the design of the product, will be very attention and strict even special request.

In addition, because transparent PC+gf plastic for melting point is high, poor fluidity, so in order to ensure the surface quality of products, often need a higher temperature, injection pressure, injection speed and other process parameters to make small adjustments, so that plastic injection can be filled with mold, and will not produce internal stress and cause product deformation and cracking. Therefore from the raw material preparation, the equipment and mold requirements, injection molding process and product raw material processing aspects to carry out strict operation.
