Production steel first articles
- Fit and cosmetic sign off tied to production tool.
- No second qualification when scale starts.
- Tool build in 10 business days on qualified programs.
Prototype injection molding
Prototype injection molding should answer design questions with parts that match production, not parts from a throwaway cavity.
Parts intent
This query is about molded parts for validation, not about buying a separate prototype mold SKU.
First shots off the NetProto hardened steel tool function as your prototypes because they come from the tool that will run production. Prototype tooling is compared with first articles from this hardened steel tool.

No MOQ; small orders run on the same steel tool.
There is no fixed prototype quantity. There is no minimum order quantity, and the same hardened steel tool runs later orders.
A very small first order often costs more per part than a later order on the same steel tool. Piece price is quoted per order.
Design changes after the steel tool is cut are quoted separately. Open questions belong in DFM before the first shots.
