The common problems that should be paid attention to in the process of plastic injection
Because transparent plastics should have high transmittance, the surface quality of plastic products must be strict, and no speckle, stoma and bleaching are allowed.Fog halo defects such as poor, black spots, color and luster, thus in the whole process of raw materials, equipment, mold, injection molding and the design of the product, will be very attention and strict and even special request.
Secondly because of the transparent plastic more for high melting point, poor liquidity, thus to ensure the surface quality of the product, often in the barrel temperature, injection pressure, injection speed make minor adjustment to the process parameters, such as when making plastic injection can not only full of mold, and won't produce internal stress caused by the deformation and cracking products.
