Due to its high light transmittance, Tongming plastic must have strict requirements for the appearance quality of plastic products, without any spots, pores, or whitening. Mist halo, black spots, discoloration, and poor gloss are the drawbacks that affect the quality of materials and equipment throughout the entire blow molding process. The planning of molds and even products requires great attention and even extreme demands. Secondly, due to the high melting point and poor activity of transparent plastics, in order to ensure the appearance quality of the product, it is often necessary to make fine adjustments to technical parameters such as machine temperature, injection pressure, and injection speed, so that the injection of plastic can not only fill the mold but also prevent internal stress from causing deformation and cracking of the product. Therefore, strict operations must be carried out in terms of material preparation, equipment and mold requirements, injection molding technology, and material disposal of goods.
