Design guidelines for Polypropylene (PP) Injection molding

Minimum wall thickness for ABS parts

A minimum wall thickness of 0.6mm to a maximum of 3.5mm should be maintained for PP parts. Lower wall thickness will cause filling issues while higher wall thickness will cause sink marks on the part

Uniform wall thickness

A uniform wall thickness should be maintained throughout the part to ensure smooth flow of material. Inconsistent wall thickness will hamper filling

Draft angles

ABS injection molded parts generally have a 1 – 2 degree draft to ensure easy removal of part from the mold

Sharp corners

A fillet has to be added in all sharp corners to ensure easy flow of material
