Quick answer

The cost of an injection mold in China depends on part geometry, mold size, cavity count, steel grade, required tool life, surface finish and validation scope. As an initial budgeting reference, simple prototype or bridge tools may fall around US$1,000–5,000, while production tooling commonly starts in the several-thousand-dollar range. Multi-cavity, hot-runner, two-shot or high-precision molds can cost tens of thousands of dollars or more. These are preliminary market references, not a supplier quotation. To compare prices accurately, confirm what each quote includes — mold design, steel and machining, trial samples, correction rounds, inspection, mold ownership and shipping.

How to read the numbers on this page This guide discusses the one-time injection mold (tooling) cost, not the recurring per-part molding price. The figures are preliminary budgeting references compiled from publicly published industry sources (reviewed October 2026). They are not audited market averages and not a Goldcattle quotation. A project-specific price requires the latest CAD model, drawing, resin grade and production volume.

What does an injection mold cost depend on?

Two molds that look similar can differ in price several times over. The cost is set by a small number of engineering choices. For each driver below, the useful question is not only "what is it" but "do I actually need it for my volume, or can it be optimized."

Cost driverWhat it isHow it changes cost / when to optimize
Part geometry & sizeOverall envelope, wall thickness, undercuts, fine detailLarger or more intricate parts need more steel and machining; simplifying geometry is the biggest single lever
Cavity countHow many parts the tool makes per cycleMore cavities raise tooling cost but lower cost per part; choose from annual volume, not first order
Steel grade & tool lifeMold steel hardness, wear resistance, target shot countHarder steels cost more but last longer and hold tolerance; match steel to volume and resin
Runner systemCold runner vs. hot runnerHot runners add cost and a controller but reduce scrap at volume; cold runners are cheaper upfront
Actions & mechanismsSliders, lifters, unscrewing, collapsible coresEach moving mechanism adds design, machining and maintenance; remove only where the part allows
Surface finishPolish grade, texture, high-gloss or matte zonesHigh finish and texture add polishing and EDM time; finish only the surfaces that matter
Dimensional toleranceTight tolerances on critical featuresOver-specifying tolerance raises machining and inspection cost; set tight tolerance only where needed
Trial & correction scopeNumber of trial (T0/T1) rounds and correction cyclesAgree how many trial and correction rounds are included; extra rounds are often billed separately
Validation & documentsDimensional reports, capability studies, customer qualificationDeeper validation and formal packages add cost; align the scope to your industry and customer needs
Lead time & loadTool build schedule and expediteExpedited builds and high shop load can raise price; plan lead time into the program, not as a rush

Injection mold cost in China by tooling type

Because "how much" is the starting question, the table below gives an initial budgeting range by tooling class. Treat it as a way to place your project in the right neighborhood before you request a formal quote.

Tooling typeInitial budget reference (USD)Typical assumptions
Prototype / bridge tool$1,000–$5,000Low-volume validation; aluminium or pre-hardened steel; limited tool life
Simple single-cavity production tool$3,000–$9,000Simple geometry, cold runner, standard surface requirement
Medium-complexity single-cavity steel tool$6,000–$18,000More complex structure, machining, polishing or tool-life requirements
4–8 cavity production tool$9,000–$40,000+Multi-cavity build; cost set by size, layout, balance and run requirements
High-complexity or high-life tool$18,000–$70,000+Hot runner, sliders/lifters, unscrewing, two-shot/overmold, precision or special finish
Important — reference only These figures are preliminary budgeting references, not a quotation. The actual injection mold cost in China depends on the part geometry, mold size, cavity count, steel grade, runner system, required tool life, surface finish, validation scope and commercial terms. The bands may overlap and are not mutually exclusive industry tiers; complex or high-precision tools can exceed the upper bound. A project-specific quotation requires the latest CAD model, drawing and production requirements.

What is included in a China injection mold quote?

Quote scopes are not standardized. Two suppliers can quote very different totals for the same part simply because they include different things. Read the scope, not just the number.

Commonly included
Mold design, steel & mold base, CNC/EDM machining, polishing, assembly, T1 trial, sample parts, dimensional report, agreed correction rounds
Often quoted separately
Freight & shipping, hot-runner controller, extra correction rounds, special inspection (e.g., extended CMM), spare parts & maintenance, export documentation

Before you compare, confirm in writing what the quote covers: how many trial and correction rounds, what inspection and reports are provided, whether the hot-runner controller is included, and what is excluded. This is the single fastest way to avoid a low headline price that grows later.

Why do injection mold quotes differ so much?

Send the same CAD file to several suppliers and you will get a spread of prices. Most of that spread is not quality — it is different assumptions. Before comparing the bottom line, align these items so you are comparing the same tool:

  • Cavity count — is everyone quoting the same number of cavities?
  • Steel grade & tool life — which steel, and for how many shots?
  • Runner system — cold or hot runner, and is the controller included?
  • Surface & finish — polish grade, texture, and which zones.
  • Sampling & correction — how many T1 samples and correction rounds are in scope?
  • Inspection & reports — what dimensional reporting is provided?
  • Ownership & delivery — who owns the mold, and on what delivery terms?

Once the configuration matches, a genuine price comparison is possible. To extend this into supplier screening and risk, see our guide on how to choose an injection molding supplier in China.

How to reduce mold cost without creating production risk

Lowering tooling cost is legitimate — but the wrong savings move risk into production. Optimize the design and the tooling plan, not the quality controls.

  • Remove unnecessary mechanisms. Eliminate sliders, lifters and undercuts where the part design allows.
  • Right-size the cavity plan. Match cavity count to realistic annual volume instead of over-building for a first order.
  • Choose the runner by volume. A cold runner lowers upfront cost; a hot runner pays back at volume through less scrap.
  • Zone the surface finish. Apply high polish or texture only where it is visible or functional.
  • Set achievable tolerances. Tighten only the critical dimensions, not the whole part.
  • Match tool class to demand. A bridge tool for validation, a production tool for volume — do not force one to do the other.
What not to do: do not treat "softer steel" or "less inspection" as free savings. Cutting steel grade, trial rounds or inspection lowers the upfront price but can raise rework, scrap, downtime and warranty risk once volume starts. Reduce cost through design and tooling decisions you can defend, not by removing the controls that protect production.

Mold tooling cost vs. total program cost

The mold is a one-time investment; the molded parts are a recurring cost. A mold quote is not the total program cost, and the per-part molding cost is a separate line driven by material, cycle time and machine time.

A practical way to see the tooling trade-off is to spread the one-time mold cost across the parts it produces:

Tooling cost per part = Mold investment ÷ Good parts produced Example with a US$8,000 tool: ÷ 2,000 parts = $4.00/part · ÷ 20,000 parts = $0.40/part · ÷ 100,000 parts = $0.08/part
Mathematical example only The figures above are a worked math example, not a Goldcattle quotation. Real projects must also account for available tool life, yield, maintenance, rework and eventual replacement; if amortized over good parts, those losses and maintenance costs cannot be ignored. For the recurring side, see the difference between tooling and molded-part cost on our injection molding services page.

What information do you need for an accurate mold quote?

A precise price needs a precise input. The more of this you can provide, the narrower — and more reliable — the range becomes:

  1. 3D CAD model — STEP or IGES of the final part geometry.
  2. 2D drawing — with critical dimensions, GD&T and tolerances called out.
  3. Resin grade — material family, grade, colour and any filler or additive.
  4. Volume — first-order quantity and expected annual volume.
  5. Tool life — target shot count and how long the tool must run.
  6. Surface & appearance — finish, texture and any cosmetic requirements.
  7. Market & compliance — end use, target market and any quality files or customer requirements.
  8. Delivery — destination and preferred Incoterms, plus timing.

If the design is not final, share the preliminary geometry and a volume range. That supports an initial assessment, but be clear it is not a fixed price until the drawing and requirements are confirmed. When you are ready, request a project-specific injection mold quote.

Frequently asked questions

How much does an injection mold cost in China?
As an initial budgeting reference, simple prototype or bridge tools may fall around US$1,000 to US$5,000, while production tooling commonly starts in the several-thousand-dollar range. Multi-cavity, hot-runner, two-shot or high-precision molds can cost tens of thousands of dollars or more. These are preliminary market references, not a quotation; the actual cost depends on part geometry, cavity count, steel grade, runner system, tool life, surface finish and validation scope.
Why do injection mold prices vary so much for the same part?
Quotes differ because suppliers assume different cavity counts, steel grades, runner systems, tool life, surface finish, sampling and correction scope, inspection depth and commercial terms. Comparing only the bottom-line number hides these differences. Align the tooling configuration first, then compare price.
What is the difference between mold cost and molding cost?
Mold cost is the one-time investment to design and build the tool. Molding cost is the recurring per-part price to produce parts, driven by material, cycle time, machine time and secondary operations. Both belong in the program budget, but they are quoted and amortized separately.
Single-cavity or multi-cavity mold - which is more cost-effective?
It depends on volume. A single-cavity tool has a lower upfront cost but a higher cost per part at volume. A multi-cavity tool costs more to build but lowers per-part cost once volume is high enough to amortize it. Choose the cavity count from expected annual volume, not from the first-order quantity alone.
How does steel grade affect mold cost and tool life?
Harder, more wear-resistant steels raise the material, machining and heat-treatment cost but extend tool life and dimensional stability. Softer steels lower the upfront price but may need more maintenance and earlier replacement. Match the steel grade to the target tool life, resin and annual volume.
What is normally included in a China injection mold quote?
A typical scope includes mold design, steel and mold base, CNC and EDM machining, polishing, assembly, trial (T1) and sample parts, a dimensional report and an agreed number of correction rounds. Shipping, hot-runner controllers, extra correction rounds, special inspection and spare parts are often quoted separately. Confirm the exact scope in the contract.
Do I own the mold, and can I move it to another supplier?
Mold ownership, storage, maintenance and the right to transfer the tool should be written into the contract. Ownership terms vary between suppliers, so confirm them before payment. A clear ownership clause protects your tooling investment and your ability to move production later.
How long does an injection mold take to make in China?
Lead time depends on complexity, cavity count and tooling load. Simple tools are generally faster than multi-cavity or high-precision tools, and trial and correction add time before parts are approved. Treat published ranges as indicative and confirm a project-specific schedule with your supplier.
When is a prototype or bridge mold a good choice?
A prototype or bridge tool suits low-volume validation, market testing or design freeze before committing to a full production tool. It uses softer materials or simpler construction, so the upfront cost is lower but tool life and tolerances are limited. Do not treat it as equivalent to production tooling.
What information do you need for an accurate mold quote?
Provide the 3D CAD model, 2D drawing, tolerances and critical dimensions, resin grade, first-order and annual volume, target tool life, surface requirements, target market and quality files, and the delivery location or Incoterms. Without a final drawing, a preliminary geometry and volume range supports an initial assessment only, not a fixed price.

How we quote a mold

We would rather give you a defensible range than a headline number that moves. When you request a mold cost estimate from us:

  • We separate one-time tooling from the recurring per-part price, so nothing is hidden in the mold line.
  • We state the assumed cavity count, steel grade, runner system, tool life and surface scope behind the number.
  • We confirm trial and correction rounds, inspection and reports, mold ownership and delivery terms in writing.
  • Mold making, engineering review and dimensional inspection are performed in-house under one ISO 9001:2015 system; some surface finishing is handled by qualified partners under our quality control.

Send your 3D CAD model, 2D drawing, resin grade and expected volume, and we will quote the mold scope against the agreed specifications — or tell you plainly what still needs to be confirmed first.
