Home Injection Mold Manufacturing Injection Mold Cost Estimator
Get a preliminary estimate of mold size, recommended cavity count, mold steel and tooling cost based on your part dimensions and production requirements. This is a budgetary estimate only. Final pricing requires review of your 3D CAD data.
Use it for early sourcing and feasibility discussions before a formal mold design is available.
Enter the finished part envelope—not the mold dimensions. For inch input, the tool converts dimensions to millimeters before applying the same engineering rules. Parts above 600 mm require a direct engineering review.
PRELIMINARY ENGINEERING BUDGET
Enter the part envelope, annual demand, material and tooling assumptions. The result will show a practical budget range—not a false-precision price.
No contact details are required to calculate an estimate.
This calculator provides a preliminary budget range only and is not a binding quotation. Final mold size, steel, cavity count, runner system, lead time, and price depend on the complete 3D geometry, tolerances, surface finish, side actions, cooling design, and other tooling requirements.
Estimated pricing excludes hot runner systems, special textures, licensed texture fees, shipping, taxes, production material, and molded-part pricing unless otherwise stated.
The estimator transfers your assumptions into this form after calculation. Add a STEP or other accepted CAD file so CKMOLD can review geometry, shutoffs, draft, undercuts, cooling access, tolerances, finish and production scope.
The model starts with part envelope and annual demand, then applies practical tooling allowances. It intentionally returns ranges because two parts with the same outside dimensions can require very different mechanisms and manufacturing effort.
Inch dimensions are converted to millimeters so one consistent ruleset is used.
Annual volume sets an initial cavity target; large part size can cap that recommendation.
Material wear, corrosion, polishing needs, complexity and volume guide the steel recommendation.
Part size provides a baseline range; cavity count, steel, resin and mechanism complexity widen it.
Special actions, very high demand and large parts are identified instead of receiving an artificial promise.
A tooling engineer reviews the complete 3D geometry before confirming size, construction, timing and price.
Mold cost is driven by the manufacturing work needed to create a repeatable process window—not by part weight alone. The largest cost changes normally come from construction, moving mechanisms, cavity count and quality requirements.
Undercuts may require slides, lifters, collapsible cores or unscrewing systems. Every moving interface adds design, machining, fitting and validation work.
More cavities can reduce part cost but increase mold size, steel, machining, balancing and cooling demands. Hot runners are quoted separately.
Glass fiber and high-temperature resins increase wear risk; PVC requires corrosion control; clear parts may require polishing-grade steel and strict handling.
Tight interfaces, optical surfaces, texture matching and witness-line limits change machining, polishing, measurement and approval effort.
Thick sections, difficult water access and distortion-sensitive geometry may need complex cooling layouts and more validation iterations.
Customer-specified components, documentation, sampling quantities, validation protocols and shipping preparation affect final scope.
Annual volume is a capacity input, not a cavity answer by itself. CKMOLD also considers cycle target, press availability, maintenance strategy, part size, projected program life and whether production risk should be split across tools.
For ordinary ABS, PP, PE and POM at lower demand, P20 / 1.2311 can be a practical budget starting point. Higher-volume conventional applications may move to 718H / 1.2738. Abrasive glass-filled materials, PPS and PEEK need higher wear resistance; PVC, transparent parts and demanding polish or corrosion requirements may justify 420 / 1.2083 / S136. Final steel selection is confirmed after reviewing geometry, resin grade, finish and expected life.
When the largest part dimension exceeds 300 mm, the estimator caps the automatic recommendation at two cavities. Above 450 mm, it defaults to one cavity and asks for engineering review because mold footprint, press tie-bar spacing, shot size and handling become controlling constraints.
Useful for early budgeting, supplier screening and program discussion.
Defines the mold that will actually be designed, built, sampled and accepted.
Use the estimate to set expectations. Use the quotation to authorize tooling.
Dimensions describe only the part envelope. The 3D model shows whether the shape can release from the mold, where shutoffs may be fragile, how steel-safe changes could be planned, and whether cooling and ejection have enough space.
In CKMOLD’s tooling review workflow, engineers use the CAD model to identify draft, wall transitions, ribs, bosses, undercuts, expected parting lines, gate candidates, ejection risks and areas likely to distort. That review is what turns a budget range into a buildable mold concept.

Direct answers for early mold budgeting and quotation planning.
It is a preliminary planning range based on part envelope, annual demand, selected resin, complexity and steel assumptions. It cannot account for full geometry, tolerances, finish, runner design, cooling, ejection or validation scope, so it is not a quotation.
No. Hot runner manifolds, controllers, specialty nozzles and related integration are excluded unless an engineer-reviewed quotation states otherwise.
Two parts with the same envelope can require completely different parting lines, slides, lifters, unscrewing systems, inserts, polishing, tolerances and cooling layouts. Those details drive design and manufacturing hours.
The form accepts STEP, STP, IGES, IGS, X_T, SLDPRT, ZIP and PDF files. A neutral 3D format plus a dimensioned PDF is usually the most efficient review package.
Yes. CKMOLD can review tooling and ongoing plastic injection molding as one sourcing scope. Production pricing is separate from the tooling estimate and depends on resin, cycle time, order quantity, quality plan and secondary operations.
CKMOLD normally responds to a complete CAD quotation request within one business day. Complex programs may first receive a short list of technical questions needed to define a reliable scope.
