Key Design Tips for Injection Molded Parts

Key Design Tips for Injection Molded Parts

Proper part design is essential for successful injection molding and cost control.

1. Maintain Uniform Wall Thickness

Uniform wall thickness helps avoid defects such as warping and sink marks.

2. Add Draft Angles

Draft angles allow parts to be easily ejected from the mold, reducing damage and improving production efficiency.

3. Avoid Sharp Corners

Sharp corners can create stress concentrations. Use fillets instead to improve strength.

4. Use Ribs for Strength

Ribs can increase structural strength without increasing wall thickness or material usage.

5. Consider Material Shrinkage

Different materials shrink at different rates. Proper design ensures dimensional accuracy.

Conclusion

Good design reduces tooling costs, improves product quality, and ensures smooth production.
