Material selection for Plastic Injection Molded Parts

In terms of material selection, we have a wide range of options that are suitable for different scenarios. General plastics such as polypropylene (PP) and polyethylene (PE) have low cost and good processing performance, and are commonly used in the manufacture of daily necessities; Engineering plastics such as polycarbonate (PC) and nylon (PA) have high strength, high temperature resistance, wear resistance and other characteristics, and are suitable for fields with high performance requirements such as automobiles and electronics; In addition, there are special plastics such as polyetheretherketone (PEEK), which have excellent chemical stability and mechanical properties and are commonly used in high-precision industries such as aerospace and medical. We will accurately match the most suitable materials for customers based on the product’s usage environment, performance requirements, and budget.

Production process of Plastic Injection Molded Parts

Our production process is rigorous and efficient, mainly including three stages: mold design and manufacturing, injection molding, and post-processing. Firstly, based on the product design drawings, professional software is used for 3D modeling of the mold to accurately design the cavity, pouring system, and other structures. Then, the mold is manufactured through processes such as CNC machining and electrical discharge machining. Then enter the injection molding process, where the plastic raw materials are heated and melted in the barrel, and injected into the mold cavity at high pressure under the push of the screw. After cooling and solidification, the mold is formed. Finally, post-processing is carried out on the formed parts, including removing burrs, secondary processing (such as drilling and tapping), annealing to eliminate internal stress, etc., to ensure that the product quality meets the standards.

Surface treatment of Plastic Injection Molded Parts

To meet different appearance and functional requirements, we offer a variety of surface treatment processes. For products that pursue beauty, spraying, electroplating, vacuum coating and other treatments can be carried out to give the product rich colors and metallic texture; If surface hardness and wear resistance need to be enhanced, hardening treatment, chemical coating and other methods can be used; In addition, logos and patterns can be added through processes such as screen printing and laser engraving; For some special requirements, such as achieving anti fingerprint and anti glare effects, we also have corresponding processing technologies to comprehensively improve product quality.

Plastic Injection Molded Parts Dimensional Inspection

We attach great importance to the dimension inspection process, using advanced inspection equipment and strict quality control system. Using precision instruments such as coordinate measuring instruments and optical measuring instruments, the key dimensions of the product are comprehensively inspected, with precision down to the micrometer level. At the same time, multiple inspection processes are implemented in the production process, including first piece inspection, process sampling, and full inspection of finished products. Once dimensional deviations are found, the reasons are immediately analyzed, and corrective measures are taken by adjusting mold parameters, optimizing injection molding processes, etc., to ensure that every component meets design standards and to ensure the stability and consistency of product quality.
