Polyurethane Injection Molding

Polyurethane injection molding is a plastic processing technique that involves injecting molten polyurethane material under high pressure into a mold and quickly solidifying it into shape. The core steps include mold design and tuning, material (polyurethane granules) proportioning and melting temperature control, and high-pressure injection molding. This process is suitable for manufacturing high-precision products such as auto parts, home appliance casings, and industrial components, featuring rapid molding and high surface smoothness. By adjusting the ratios of auxiliary materials like catalysts and stabilizers, the product's mechanical properties and weather resistance can be optimized to meet the needs of various industrial applications.
