Pick the process for the quantity, not the part
The same part can be machined, formed, cast or printed. At low quantities the decision is dominated by tooling and setup, not cycle time. A machined part with no tooling often beats a molded part that needs a tool, even when the molded unit cost looks better on paper.
- No-tooling routes: machining, sheet metal, fabrication, additive
- Soft or bridge tooling where a molded form is required
- Production tooling only once demand is proven
Shops that want low-volume work
High-mix shops are organized around frequent changeovers and short setups; production plants are organized around long runs. Both will quote, but only one is structured to make money on your job, and that shows up in price and lead time.
What makes a low-volume RFQ quotable
Send the quantity you want now and any realistic repeat, a drawing or model, material, finish and the tolerances that actually matter. Marking which dimensions are critical often removes more cost than any negotiation.
What to look for in a supplier
- Comfortable with your quantity as a standing order size
- Short setup and changeover practice
- In-house or trusted finishing partners
- Clear minimum order value, stated up front
Certifications buyers often need
- ISO 9001 for a documented quality system
- Industry registrations only where your product needs them
- Material certifications and traceability when the application requires it
Questions to ask prospective manufacturers
- What quantity range do you run most often?
- What is your minimum order value, separate from piece price?
- What would this part cost at 10, 50 and 250 pieces?
- Which tolerances on this drawing are driving the price?
Frequently asked questions
- What counts as low volume?
- There is no fixed threshold. In practice, low volume means a quantity where setup and tooling dominate the unit price — often single units to a few hundred pieces, depending on the process.
- Will I pay more per part?
- Usually yes, because fixed setup is spread across fewer pieces. The way to reduce it is to remove unnecessary tolerances and finishes, not to push the supplier's rate down.
- Can the same supplier scale with me?
- Some can, some cannot. Ask directly what their upper comfortable volume is, and plan the transition before you need it.
