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.

Overmolding injection molding is a molding process in which one material is injected and covers another material.

Dimensional variations in molded parts are a common problem during the injection molding process. These variations can significantly affect product quality and impact a product's fit, function, and appearance.

Selecting the right injection molding machine is crucial for ensuring the quality and efficiency of your plastic products.

Polyphenylene sulfide (PPS) is a high-performance engineering thermoplastic renowned for its excellent heat resistance and chemical resistance. Due to its high melting point, precise temperature control is crucial during injection molding.

The injection system of a molding machine refers to the channel through which molten plastic flows from the nozzle of the injection machine into the mold cavity. It consists of a main runner, sub-runners, a gate, and a cold slug.

Injection molding is the most common method for producing plastic products. It involves injecting heated, molten plastic into a mold, where it cools and solidifies into the desired shape.
