  • Basics of Injection Molding Design

    2021-12-4u2002·u2002The wall thicknesses of an injection molded part generally range from 2mm – 4mm (0.080' – 0.160'). Thin wall injection molding can produce walls as thin as 0.5mm (0.020'). The chart below shows recommended wall thicknesses for common injection molding resins. Uniform Wall Thickness: Thick sections take longer to cool than thin ones.
