In modern manufacturing, injection molding is a cornerstone of plastic product production. A seemingly ordinary piece of equipment in an injection molding plant, the mixer, plays a crucial role in ensuring product quality.

By selecting appropriate materials, designing effective molds, and implementing precise injection molding processes, manufacturers can produce high-quality over-molded products.

TPU (Thermoplastic Polyurethane) is widely used in various industries due to its excellent elasticity, abrasion resistance, and oil resistance. However, TPU injection molding has its unique characteristics, and mastering the following five key points is essential for producing high-quality TPU products.

Polyphenylene sulfide (PPS) is a high-performance engineering plastic, renowned for its excellent heat resistance, chemical resistance, and electrical insulation properties. It finds extensive applications in electronics, automotive, and aerospace industries. However, due to its high melting point and rapid crystallization rate, injection molding of PPS presents certain challenges.

PC + ABS plastic is an alloy plastic that combines the advantages of polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS). The drying temperature is usually between 80 - 100 °C.

A simple mold, in the injection molding industry, typically refers to a mold with a relatively simple structure, short manufacturing cycle, and low cost. Compared to complex and multifunctional precision molds, simple molds have simplified designs and manufacturing processes, but can still meet basic molding requirements.

Mold deformation is a common production issue that directly impacts product quality and production efficiency.

Flash is a common defect in injection molding that affects the surface quality and dimensional accuracy of products, reducing their overall value.

The filling stage is a crucial phase in the entire injection molding process, directly influencing the performance and appearance of the final product.

A 3D drawing is the cornerstone of cost estimation for injection molded products.
