How much do you know about part design rules?

Hereby, we would like to share some shallow view on part design rules:


·Simple shapes to reduce tooling cost (No undercuts, etc.)


·Draft angle to remove part


-In some cases, small angles (1/4°) will do


- Problem for gears


·Even wall thickness


·Minimum wall thickness~-.025 in


·Avoid sharp corners


·Hide weld lines


-Holes may be molded 2/3 of the way through the wall only, with final drilling to eliminate weld lines


We are automobile molding manufacturer,incliding fuel pump mold and oil circuit mold.


Welcome to leave messages and share with us your opinions on it!
