Plastic strips are common plastic products in life, usually used for sealing, protection, decoration or as functional components. Widely used in construction, automobile, electronics, electrical appliances and other fields.
The injection molding process is one of the ways to produce plastic strips. Molten plastic is injected into the plastic strip mold, and the plastic strip product is obtained after cooling. Universe Plastic Engineer introduces to you how to produce plastic strips through injection molding process.
Plastic strip injection molding production steps
1. Plastic strip mold design
Design and manufacture plastic strip molds according to the shape and size of the plastic strips, which requires a professional mold manufacturing company to complete. The final test is to obtain the sample, and whether the sample is qualified determines the completion of mold manufacturing.
2. Material preparation
Purchase plastic raw materials and add additives as needed, such as plasticizers, antioxidants, fillers, etc., to ensure that the material properties meet the mold production requirements.
3. Injection molding manufacturing
Through the reasonable operation of the injection molding machine and mold by the injection molding engineer, the material is heated, melted and injected into the mold. After the material is cooled and solidified in the mold, the plastic strip is taken out of the mold.
4. Post-processing
After injection molding, the plastic strips are subjected to post-processing, such as trimming, cutting, surface treatment, spraying, quality inspection, etc., to ensure that the products meet delivery requirements.
