PPS (Polyphenylene Sulfide) is a high-performance engineering plastic known for its excellent heat and chemical resistance. However, due to its high melting point, temperature control is critical during the injection molding.

Runner adhesion is a common issue in injection molding that can negatively impact production efficiency and product quality.

Protecting molds during injection molding not only extends their lifespan but also enhances production efficiency and product quality.

Residual stress in injection molded parts refers to internal stresses that remain within the product after the molding process. These stresses are caused by non-uniform shrinkage, molecular orientation, and other factors that occur during the filling of the mold and subsequent cooling and solidification of the molten plastic.

The production of medical devices places stringent requirements on the precision, complexity, and materials of injection molds. As medical technology advances and the demand for personalized healthcare grows, medical injection molds are evolving to meet increasingly complex manufacturing needs.

In injection molding, controlling the plastic temperature is a crucial factor. The required processing temperature varies depending on the type of plastic.

PPS (Polyphenylene Sulfide) is widely applied in various industries due to its excellent heat resistance, chemical resistance, dimensional stability, and electrical insulation properties.

The design of cooling circuits in precision injection molds is a critical factor affecting product quality and production efficiency. A well-designed cooling circuit ensures uniform cooling of the molded part, reduces cycle time, and improves dimensional accuracy and surface finish.

Sink marks are a common surface defect in injection-molded products, typically appearing as localized depressions or wavy patterns on the surface. Their formation is primarily related to material properties, mold design, and molding process parameters.

Plasticizers are commonly used additives that play a crucial role in injection molding. Their addition can significantly improve the processing properties of plastics and the performance of the final product.
