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.

Food-grade injection molding is a process that requires strict adherence to food safety standards. Every step must be meticulously controlled to ensure the final products meet the requirements for food contact materials.

UV treatment is a common surface finishing process for plastic injection molded parts. This process involves applying a UV-curable coating to the plastic surface and exposing it to ultraviolet light. The UV light generates a rapid curing reaction, forming a hard, durable, and glossy protective film. This process not only enhances the appearance of the plastic parts but also improves their properties such as abrasion resistance, chemical resistance, and weatherability.
