Polyethylene (PE) is a thermoplastic resin made by polymerization of ethylene. It is insoluble in general solvents at room temperature, has low water absorption and excellent electrical insulation.

Safety isn’t just a priority—it’s a mandate when producing plastic components for food contact. Manufacturers are required to meet strict regulations to protect consumers and ensure product integrity.

Injection molding involves injecting molten plastic into a mold, cooling it, and ejecting it. Manufacturers can repeat the process to quickly and cost-efficiently to create thousands of identical parts.

Since its inception in the 1960s, to its acceptance in the 1990s, the hot runner system has challenged tradition across the plastic injection molding business. 

The demand for innovative, new plastic products that are lighter, faster, stronger and less expensive than metal ones has gained incredible traction in the last decade. Many Original equipment manufacturers (OEMs) have been moving toward the innovative possibilities that engineered resins offer. Proper material selection is a critical injection molded part design consideration to ensure the finished product survives its intended use, environment and compliance requirements. 

Ejector pin marks usually refer to the glossy or white imprints on the surface of a injection molded product, as well as the different levels of glossiness – dark or shadow, without convex or concave – visible directly opposite to the ejector pin location.

Injection molding involves melting and injecting plastic into a mold, cooling it, and ejecting the finished product. Injection molding is used across various industries, but it’s particularly instrumental in the medical supply and device industry, as it can produce large quantities of accurate, high-quality parts and is compatible with many medical-grade plastics.
