Polyurethane Injection Molding

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