MAKE THE FIRST BATCH POSSIBLE

A mold designed for your stage.

Tooling can dominate the cost of a short production run. The starting point is a review of what your part needs—and which tooling features can be simplified.

01

Simplify the mold

Review a single-cavity layout, straightforward parting lines and practical insert options. Reduce unnecessary complexity where the part design allows.

02

Choose suitable tooling

Discuss aluminum, soft steel or a simplified insert approach. Resin, geometry, surface quality and expected shot count guide the recommendation.

03

Approve samples, then run

Review trial parts against agreed dimensions and appearance criteria. Confirm any changes and approve samples before the agreed production batch.

See the mold cost and the batch cost separately.

Request a quote that distinguishes tooling, trial samples, molded parts and any secondary operations. Compare the total project cost at your first batch quantity and at a possible repeat quantity, including any repeat-run setup charges.

A simpler tool may reduce the upfront commitment. The right choice still depends on part complexity, resin and total demand.

CHOOSE FOR THE WHOLE PROJECT

When a small-batch mold makes sense.

A stable design and a need for molded resin parts are useful starting points. We review your priorities before recommending a route.

Your priorityRapid tooling / small-batch moldingAnother route to consider
Design changes every iterationQuote once the main geometry is ready; later changes may require tool rework.3D printing or CNC for early geometry checks.
Pilot launch or limited demandReview simpler tooling, trial samples and a defined first batch.Compare total cost with printed or machined parts.

Complex undercuts, tight cosmetic requirements, abrasive resins and high shot counts may change the proposed tooling strategy. Tool suitability is confirmed during review.

START WITH THE PART’S REQUIREMENTS

Your resin. Your application.

Request the resin family you need, then specify the exact grade, color and performance requirements. Availability and process suitability are reviewed with your files.

ABS / PC-ABS

Enclosures, covers and product housings.

Tell us about impact, temperature and appearance.

PC

Parts with specific strength or optical requirements.

Mark clear surfaces and cosmetic acceptance criteria.

PP

Lightweight functional parts and flexible features.

Identify living hinges, chemical exposure and fit.

PA / POM / other

Engineering components with application-specific needs.

State the grade, fillers, wear and dimensional requirements.

Upload your design and tell us how many parts you need. Request a tooling proposal and a reviewed batch quote.

  1. 01
    Design & feasibility review

    Discuss draft, wall sections, undercuts, gates, ejector marks and critical fits.

  2. 02
    Tooling proposal & quotation

    Confirm tool construction, cavities, expected life, samples, costs and lead time.

  3. 03
    Trial samples & approval

    Review the trial parts and agree any changes before batch production.

  4. 04
    First batch & future orders

    Confirm inspection, delivery, mold ownership, storage and repeat-order terms.

    CLEAR ANSWERS BEFORE YOU COMMIT

    Small-batch tooling, explained.

    What does “simplified mold” mean?

    It means matching the tool construction and features to the actual project rather than assuming a long-life, high-output production mold. The proposal may involve a single cavity, aluminum or soft-steel tooling, or simplified inserts. The suitable approach depends on your part and resin.

    Can I request only 100 or 500 parts?

    Yes—submit that quantity for review, or enter another quantity. We assess the total tooling and batch cost before confirming feasibility, pricing and any minimum order. Very small quantities may be better suited to another process.

    Is this real injection molding or vacuum casting?

    This service concerns thermoplastic injection molding with a mold. It is separate from silicone-mold vacuum casting. The proposed resin grade and process will be specified in the quote.

    How much can I save on the mold?

    There is no fixed saving percentage. Geometry, cavities, material, finish, tool life and secondary operations affect the quote. Compare the full project cost, including tooling, samples and parts, at your planned quantities.

    How many parts will the mold produce?

    Tool life is project-specific. Resin abrasiveness, mold material, geometry and maintenance all matter. The proposed service life and repeat-order conditions must be agreed before tooling starts.

    Can I change the design or order more parts later?

    Ask us to review the change before committing to it: some changes need inserts or rework, while others require a new mold. Repeat orders depend on the agreed tool life, condition, storage and availability.

    Who owns the mold, and is it stored for repeat orders?

    Mold ownership, storage period, maintenance, transfer or delivery options and any associated charges are confirmed in the quotation or order agreement. Include any specific requirement in your brief.

    Does this form place a paid order?

    No. It saves your files and requirements for review. Tooling charges, unit prices, sample approval, schedule and production terms must be agreed before work begins.
