Polyethylene (PE)
PE is a widely used material in the plastics industry and is frequently used in injection molding. According to the polymerization pressure, PE can be divided into three types: high pressure, medium pressure and low pressure. PE is easy to deform, has a high shrinkage rate during molding, and has a slow cooling rate. plastic molding manufacturing inc often use PE to manufacture products such as plastic pipes, plastic ropes, fresh-keeping bags and food boxes.
Polypropylene (PP)
PP is a relatively light plastic raw material. It has high tensile strength and high compressive strength, is resistant to high temperatures and does not absorb water. It can be sterilized under high temperature conditions. Injection molding manufacturers can not only make PP into products such as pump impellers, automotive parts and insulators, but also widely use it in the medical industry to make various medical supplies.
Polyvinyl chloride (PVC)
PVC has a low purchase cost, so it has become one of the commonly used raw materials in injection molding. PVC has good chemical stability and is suitable for making corrosion-resistant pipes, oil pipelines and artificial leather. During the injection molding process, stabilizers and lubricants are usually added to ensure that it does not release toxic gases and improve the quality of injection molded products. However, PVC has poor heat resistance and thermal conductivity, so you need to carefully choose the process when processing it and try to use injection molding processing equipment.
If you are looking for a custom plastic mold supplier in China, you can consider some reputable manufacturers who provide professional injection molding services and high-quality thermoplastic products to meet the needs of different customers.
