The wall thickness of the cylindrical boss should not exceed 60% of the main part wall thickness.
: Apply a taper (usually 1 to 2 degrees ) to all surfaces parallel to the mold opening direction to ensure easy part ejection. injection molding part design for dummiespdf exclusive
Injection molding part design is a specialized engineering discipline centered on Design for Manufacturability (DFM) The wall thickness of the cylindrical boss should
When molten plastic is injected into a mold, it begins to cool and shrink. Thick sections of a part hold heat longer than thin sections. This uneven cooling creates internal stresses, leading to major defects. Why Uniform Walls Matter injection molding part design for dummiespdf exclusive
