Key takeaways
- Tooling cost and unit cost are a pair — never evaluate one alone
- Cavity count and expected tool life belong in the quote comparison
- Plan for T1/first-off samples before bulk resin buys
- DFM changes are cheapest before steel is cut
Is moulding the right process?
If you need hundreds of thousands of identical plastic parts, moulding often wins. If you need fifty complex parts next month, CNC or additive may be better.
When unsure, ask for indicative economics at your real volumes — not catalogue fantasy volumes.
Tooling basics that affect price
Soft tools can be faster/cheaper for lower volumes; hard tools last longer for higher volumes. Hot runners, side actions, and texture all add cost.
Clarify ownership, storage, maintenance, and what happens if you move production later.
Samples and design changes
Expect iterative samples. Agree how many revision rounds are included and how steel changes are priced after approval.
Changing a dimension after tooling starts is not a small email — it can be a new machining operation on expensive steel.
Questions for every moulding quote
What material and grade? What shrinkage assumptions? What cosmetic standard? What packing? What lead time to T1 and to bulk? What is excluded?
