Injection-molded polymers can streamline assembly steps and eliminate secondary finishing processes, such as protective coatings and paint, enhancing production efficiency. Engineered polymers and specialty composites are gaining popularity because they can achieve metal-like performance while providing design flexibility through injection molding. LFTs still offer the ease of injection molding, like short-fiber polymers, but the fiber length and type (glass, carbon, etc.) are key factors in the strength, stiffness, and durability of plastics.

Options to use special effects including molded-in metallic, frost effects, glow-in-the-dark or laser marking Offered a paint replacement solution with a molded-in-color metallic effect Smartbatch™ Blow Molding
