Rapid Tooling Quote Checklist: Mold Cost, Samples and Repeat Runs

Compare rapid tooling proposals using the complete first-batch scope, sample approval plan, resin specification and repeat-order terms rather than mold price alone.

Quote a defined part and a defined production plan

Give each proposal the same part revision, drawing and material requirements. State the first batch quantity, expected repeat demand and the purpose of the pilot run. This makes it possible to understand why two tooling approaches differ.

In a DIYIPCB rapid tooling enquiry, submit a ZIP containing the model and include a PDF drawing. Mark critical fits, visible surfaces, resin grade, color and any inserts or secondary work.

If demand or a design detail is uncertain, identify the uncertainty explicitly. An assumption that is visible in the request can be discussed; an assumption left unstated can become a disagreement after tooling has started.

Separate the mold price from the batch price

Ask for a breakdown of tooling, trial samples, molded parts and agreed secondary operations. Record what is included in each line and whether a charge is one-time, per batch or per part. Confirm any delivery-related scope separately.

To compare the first batch, add the quoted tooling and sample charges to the quoted batch and agreed additional work. For a repeat batch, use the repeat-run assumptions rather than automatically dividing the initial tooling charge across a forecast that may never be ordered.

Keep hypothetical quantities clearly labeled. A calculation is a planning scenario, not a commitment by either side to a future unit price or available capacity.

Compare tooling assumptions before comparing totals

Record the proposed mold construction, material, cavity count and intended production use. Ask how the selected resin, geometry and finish affect the approach and what would require a different tool strategy.

Two proposals can quote the same CAD file while making different assumptions about cosmetic surfaces, sample work, maintenance or expected service. Clarify those differences before treating the lower total as a better fit.

There is no useful universal saving percentage for every rapid tooling project. The meaningful comparison is between accepted proposals for the same requirements, with their limitations and included work stated clearly.

Define sample work and the change process

Agree how many trial parts are included, what inspection information accompanies them and who will approve the result. Identify the functional assembly tests and appearance references before samples are produced.

Ask how a deviation will be reported and resolved, and how a customer-requested design change would be reviewed and priced. Specify whether an accepted revision requires another sample review before production authorization.

Keep the record practical: issue, drawing reference, proposed action, approval and updated revision. That record is more useful for the production handoff than a series of untracked messages saying that the sample is almost correct.

Put repeat-run and storage terms in writing

Discuss mold ownership, storage period, maintenance responsibilities and any conditions for a repeat order. Ask what happens if the tool needs repair or a later design revision requires new inserts or a replacement mold.

For each repeat-order scenario, identify the assumed quantity, resin, finish and inspection scope. Record whether additional setup or other charges apply. Confirm any transfer or delivery requirement before choosing the tooling route.

Do not treat a proposed tool life as a guarantee of every future order’s availability or unit cost. The intended use, condition and agreed terms need to be reviewed together, especially when demand changes substantially.

Use a comparison sheet with consistent rows

• Part revision, model and drawing references.
• Resin grade, color, finish and critical requirements.
• Tool construction, cavities and agreed intended use.
• Tooling charge and included sample work.
• First batch quantity, part price and secondary operations.
• Inspection and approval responsibilities.
• Repeat-run assumptions, setup and storage terms.
• Ownership, maintenance, change and transfer provisions.
• Quoted schedule and delivery scope.

List open questions beside the affected row and resolve them before authorization. Retain the accepted comparison with the purchase record so the first batch and any later order can be checked against the same agreed scope.
