On demand molding
On demand injection molding sounds like manufacturing without inventory. Behind it is still a mold, ownership, and reorder pricing.
Model
Marketplaces promise parts when you need them. Sustainable on demand injection molding requires a stable cavity and clear ownership.
NetProto keeps the same hardened steel tool for your program. You own the mold once the tooling charge is paid, and reorders run without rebilling the tooling charge.
Ownership
| Question | Why it matters |
|---|---|
| Who owns the mold? | Determines whether you can change suppliers |
| Same cavity every order? | On demand breaks if each PO uses different steel |
| Tooling on reorder? | Hidden fees destroy unit economics |
