Same hardened steel tool
- First and reorder parts from identical cavities.
- Tooling charge not billed again on reorders.
- Tooling completed in 10 business days on qualified programs.
Low volume molding
Low Volume Injection Molding: Cost Per Part and Break Even
Low volume does not have to mean a new tool every order. It means how tooling capital spreads across fewer parts per year.
Volume band
Low volume with one production tool
Low volume injection molding searches worry that steel tooling only works at massive scale. Tooling capital still amortizes across every part you buy over the program life.
NetProto has no minimum order quantity. A small first order does not force a different tooling approach or a throwaway cavity. See on-demand injection molding for later orders on that same tool.
Economics
What changes at low volume
| Factor | Effect at low annual volume | NetProto approach |
|---|---|---|
| Tooling amortization | Higher per part share of capital | One steel tool, many small orders |
| Cycle time | Still drives piece price | Quoted per production order |
| Second tools | Often proposed elsewhere | Avoided with one steel path |
Orders
Repeat orders on one tool versus new tool per batch
New tool per low batch
- Sampling restarts each time.
- Correlation risk between batches.
- Capital spent repeatedly.

An aluminum mold is often compared with one hardened steel tool. Low volume still uses that steel tool.

Low volume questions
Is there an MOQ?
No minimum order quantity.
Does low volume require aluminum?
An aluminum mold is often compared with steel for a short run. NetProto quotes one hardened steel tool, often priced competitively with US-made aluminum tooling.
How does tooling amortization work at low volume?
The tooling charge is paid once for the hardened steel tool. Later orders on that same tool do not bill the tooling charge again. Piece price is quoted per order.
Can I start with low volume and scale up?
Yes. There is no minimum order quantity. The same hardened steel tool keeps running as orders grow, and the tooling charge is not billed again.
