The design points for injection molds for automotive interior parts encompass various aspects, from mold structure and material selection to process parameters.

Venting design on the parting surface of injection molds is a crucial aspect of ensuring product quality. If air and volatile gases within the mold cavity are not effectively expelled, defects such as voids, burn marks, and surface flaws may occur. Proper venting design can significantly improve the appearance and performance of products while enhancing production efficiency.

The spiral cooling system is a high-efficiency cooling structure that uses spiral-shaped cooling channels within the mold to enable uniform flow of the cooling medium. This design rapidly removes heat and is particularly suitable for injection-molded products with uniform wall thickness, symmetrical shapes, or high cooling efficiency requirements.

Drying raw materials is a critical step in injection molding, significantly impacting product quality, production efficiency, and cost control.

BOM (Bill of Materials) tables can significantly enhance the efficiency of injection mold production.

Glass fiber-reinforced injection molded parts are widely used in automotive, electronics, and household appliances due to their superior strength, rigidity, and heat resistance. However, meeting higher performance requirements necessitates a focus on enhancing the mechanical properties of these parts.

A draft angle refers to the angle between the mold cavity surface and the mold’s parting line. The presence of this angle allows injection-molded parts to be smoothly ejected from the mold after cooling and shrinkage.

POM (Polyoxymethylene) injection molding is widely used in various fields due to its unique physical and chemical properties, and it has a broad application prospect. With the advancement of technology and the changing market demands, the scope of POM injection molding applications continues to expand.

Surface treatment for automotive interior injection molds aims to enhance mold performance, improve product quality, and extend mold lifespan.
