Tips needed on injection molding my product

Not if you want a 0.4 draft and your Chinese vendors want 1-2.

The 50% increase in in wall thickness is somewhat problematic, but I’ll assume the gating is on the cavity side and won’t be to much of an issue.

I think the problem is the 0.4 on the cavity side. The core with 1 will release first and you will have a stuck part. My guess is that our tooling guy will want to create an undercut on the core side to ensure hold.

Are you starting with a prototype tool or are you jumping right into production tooling?
