Do you understand the injection molding process of transparent plastic products?
Characteristics of commonly used transparent raw materials
Due to the high light transmittance of transparent plastics, it is inevitable that the surface quality of plastic products should be strict, and there should be no defects such as spots, pores, whitening, fog halo, black spots, discoloration, and poor gloss. Therefore, during the entire injection molding process, great attention should be paid to and strict or even special requirements should be put forward for the design of raw materials, equipment, molds, and even products.
Secondly, due to the high melting point and poor fluidity of transparent plastics, in order to ensure the surface quality of products, it is often necessary to make subtle adjustments to process parameters such as higher temperature, injection pressure, and injection speed, so that when injecting plastic, it can not only fill the mold, but also not generate internal stress that causes deformation and cracking of the product.
