About clear plastic

Transparent plastic products refer to those products that use transparent plastic materials during the manufacturing process and have transparent properties.

Transparent plastic products are widely used in various fields such as electronics, automobiles, construction, daily necessities, etc. due to their excellent transparency, good strength and wear resistance, good heat resistance and chemical stability.

Transparent plastic products have become more and more popular among consumers in recent years, especially when the "minimalist style" prevails. White, translucent white, and transparent colors have become people's first choice. It has become an indispensable and important part of modern industry and daily life.

Transparent plastic type features

The types of transparent plastic raw materials include polymethyl methacrylate (acrylic or organic glass PMMA plastic), polycarbonate (PC plastic), polyethylene terephthalate (PET), transparent nylon, etc.

The main characteristics of transparent plastic are high transparency, good strength and wear resistance, impact resistance, good heat resistance, excellent chemical resistance, low water absorption, etc.

Transparent plastic injection molding

Clear plastic injection molding is a complex process that requires attention to many factors to ensure product quality and performance.

1、Raw material preparation

Transparent plastics have very high transparency requirements, so during storage, transportation and feeding, attention must be paid to the cleaning and sealing of raw materials to prevent any impurities from entering the raw materials and affecting the transparency and quality of the product.

2、Equipment and mold requirements

During the entire injection molding process, attention must be paid to the cleaning of the equipment and molds to prevent any impurities from entering the equipment and molds and affecting the quality of the product. At the same time, in order to prevent raw material contamination and the presence of old materials or impurities in the recesses of the screw and accessories, especially the presence of resins with poor thermal stability, screw cleaning agents should be used to clean all parts before use and after shutdown to prevent them from sticking. miscellaneous.

3、Injection molding process

During the injection molding process, in order to ensure the surface quality of the product, the process parameters need to be finely adjusted. For example, in order to ensure the transparency of the product, injection molding must be carried out at a higher temperature, injection pressure, injection speed and other process parameters. At the same time, in order to ensure the surface quality of the product, it is often necessary to perform injection molding at a higher temperature, injection pressure, injection speed and other process parameters. Make subtle adjustments so that the mold can be filled with plastic when injecting plastic without generating internal stress that may cause product deformation and cracking.

4、Product handling

In terms of product handling, in order to prevent surface quality from deteriorating, release agents are generally used as little as possible during injection molding; when recycled materials are used, the proportion of release agents should not exceed 20%. For recycled materials, hot runner molds should be used as much as possible to reduce cooling time and improve product quality. During the cooling process of the product, the possibility of warping and deformation should be avoided as much as possible.
