Advantages of PC injection molding
Polycarbonate is a good material when you need high impact strength and durability with temperature resistance. It has a part cost compared to other plastics but makes it up by having high strength and thermal properties with an excellent surface finish
- Good dimension stability
- Heat resistance
- Impact resistance
- Scratch resistance
- Can be made Flame and UV retardant

Design guidelines for Polycarbonate Injection molding
Minimum wall thickness for PC parts
A minimum wall thickness of 1.2mm to a maximum of 4mm should be maintained for PC 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
