WALL SECTION CONSIDERATIONS

WALL THICKNESS

    Cost savings are highest when components have a minimum wall thickness, as long as that thickness is consistent with the part’s function and meets all mold filling considerations. As would be expected, parts cool faster with thin wall thicknesses, which means that cycle times are shorter, resulting in more parts per hour. Further, thin parts weigh less, using less plastic per part. On average, the wall thickness of an injection molded part ranges from 2mm to 4mm (.080 inch to .160 inch). Thin wall injection molding can produce walls as thin as 0.5mm (0.020 inch).
