Injection Moulding Tool Costs for Medical Devices: A 2026 Buyer’s Guide

July 2026

Whether you’re evaluating outsourcing your medical device manufacturing entirely, or you handle production in-house but need a partner for injection moulding, one question tends to come up early: how much is the injection moulding tool going to cost?

It’s a reasonable question, but not one with a single answer. We’ve seen injection moulding tools quoted at anything from £2,000 for a simple prototype tool to over £80,000 for a validated, multi-cavity production tool for a disposable device. The cost depends entirely on the complexity of tool required to manufacture your medical device.

As a contract medical device manufacturer that has been moulding parts in-house and sourcing injection moulding tools through trusted partners for medical device companies for over 35 years, we are asked this constantly during early-stage conversations. This guide walks through what drives injection moulding tool cost, what changes when a part is destined for a patient-contact device rather than a consumer product, and what to budget for in 2026.

If you are looking for information on the full costs of medical device manufacturing (materials, cleanroom assembly, regulatory, and more), we have covered this in our guide, Key Factors Influencing Medical Device Manufacturing Costs.

Injection Moulding Tool Cost Ranges at a Glance

For a standard industrial or consumer part, injection moulding tools typically range from around £2,000 for a simple single-cavity prototype tool to £80,000+ for a complex, high-cavity production tool.

For medical devices, you should generally expect that range to shift upward. A single-cavity injection moulding tool for a simple component, such as a syringe barrel or a basic housing, might land between £8,000 and £16,000. A multi-cavity production tool for a more complex disposable device can reasonably reach £50,000 – £100,000. Tight-tolerance or cleanroom-critical parts can push costs higher still.

This isn’t down to profit margin, it reflects cost of materials including your gating system and machining hours required to manufacture the tool.

Why Medical Injection Moulding Tooling Costs More Than Standard Estimates

Search around for injection moulding costs and you’ll find plenty of generic pricing guides. Most of them aren’t wrong, they’re just not describing medical tooling. A number of factors specifically increase the cost of an injection moulding tool destined for a regulated device:

Tool steel selection.
Many industrial injection moulding tools are cut from pre-hardened steels like P20, which are perfectly adequate for lower-volume or less demanding applications. Medical programmes, particularly higher-volume disposables or anything running corrosive or filled materials, more often justify fully hardened steels such as H13 or corrosion-resistant grades. The additional cost buys tool longevity, tighter long-term tolerance control, and resistance to wear, which is important because validated processes are expected to run unchanged for years without deviation.

Gating strategy.
The gating strategy agreed during the DFM stage has a direct impact on overall tool cost and long-term production efficiency. The most appropriate approach will depend on projected volumes, cavity count, material behaviour, part geometry, and whether secondary trimming operations are acceptable.

For low-volume tools, a conventional cold-feed system is often the most cost-effective option, although post-mould trimming may be required. For a single-cavity production tool, a cold sprue and gate or a single-drop open hot-tip system may be suitable, depending on the part design and acceptable gate vestige. For multi-cavity tools, the options become more varied, but a sequential valve-gated hot-runner system is commonly used where greater control, balance, and repeatability are required.

Tolerance and finish requirements.
A part that mates with a drug delivery mechanism, seals against a fluid path, or forms part of a sterile barrier is rarely built to the ±0.05mm tolerances common in consumer parts. Tighter tolerances require additional EDM (Electrical Discharge Machining) and polishing hours, and labour is where the majority of injection moulding tooling cost comes from, machining and finishing typically account for 40 – 50% of total tool cost. Material choice also plays a role in the higher price, medical-grade and biocompatible polymers carry their own cost premium separate from the tool itself, which we’ve explored further in What Factors Influence the Cost of Injection Moulding of Medical Devices?

Cleanroom-compatible design.
Where injection moulding takes place in an ISO Class 7 or 8 cleanroom, the tool itself often requires design features that support cleaner handling and minimise the risk of particulate generation, which adds upfront engineering time.

Process Validation.
This is the most significant factor, and one that most generic pricing guides for injection moulding tools almost never address. Under ISO 13485 and equivalent FDA requirements, injection moulding is classed as a process that can’t be fully verified by inspecting the finished part alone, meaning the process itself must be validated rather than approved by eye. This requires Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ): documented evidence that the tool is installed correctly, that the process operates reliably across its full parameter window, and that it consistently produces conforming parts over multiple production lots. This typically adds several weeks before the first finished parts are ready and checked and increases the overall tooling budget. It is not optional, and any quote that leaves it out is not comparable to one that includes it.

Documentation and traceability.
Full lot-level traceability of materials, tooling history, and process parameters must be built into the plan from day one, not retrofitted after the tool is cut.

Injection Moulding Tool Cost Breakdown by Type

These are indicative ranges, not quotes, and are more suited to medical tool within smaller press ranges, up to 300T. Every injection moulding tool is different, and the only way to get a reliable figure is to conduct a Design for Manufacture (DFM) review against your actual CAD.

The Risks of Selecting an Injection Moulding Tool Supplier on Price Alone

A cheaper overseas tooling quote can look like a substantial saving upfront, but the risk is that the tool arrives, fails to hold tolerance, and needs rework or a full re-cut. The programme then slips by months, and by the time the issue is resolved, the expected savings have evaporated several times over, with the delay costing far more than the money saved.

This isn’t a case for choosing the most expensive quote by default. It’s a case for making sure whoever prices your tool understands that a part destined for a patient carries different engineering and compliance demands than a consumer part, and has quoted accordingly.

Key Questions to Ask Before Commissioning an Injection Moulding Tool

• What steel grade are you specifying, and why? Is it matched to my actual production volume and material?
• What gating strategy are you specifying, and why?
• Is validation (IQ/OQ/PQ) included in this quote, or is it a separate cost I need to budget for?
• Will this tool be built and run in a facility with relevant ISO 13485 and cleanroom capability, or does moulding happen elsewhere?
• What’s the full lead time including validation and shipping of tools, not just tool build?
• How is change control handled if a design revision is needed after the tool is cut?

Getting an Accurate Injection Moulding Tool Quote

If you are still in the early stages of sourcing a medical device, comparing suppliers, checking your budget, or establishing whether outsourcing tooling and injection moulding makes more sense than an in-house approach, the most reliable starting point is a Design For Manufacture (DFM) conversation. We source tooling through trusted, experienced partners, with every design reviewed in-house by our own tooling manager before a tool is ever cut. This combination means you get the benefit of specialist toolmaking expertise, quality-controlled by someone who understands the specific demands of medical device manufacturing. A brief review of your CAD will tell you more about likely cost than any pricing table, including this one.
