Custom Design and Production at Carmo

Engineering & injection moulding

Contract manufacturer of injection moulded plastic components. Medical and technical. Espergærde, Denmark.

In short: Carmo is a Danish, ISO 13485-certified development and production partner: one engineering team carries your part from concept to regulated volume production; the project doesn’t change hands, and there is no new supplier to qualify.

“At Carmo, we have the knowhow and technology to develop and manufacture the component you need smarter, faster, and at a low cost.”

Anders Johnsen, VP R&D and Technology

Who this is for

Finite capital and a funding clock: the supplier you prototype with is usually the one you scale with. Carmo Print Moulding gets you a functional proof-of-concept before definitive tooling has to justify itself. Bring the problem, not a finished spec.
A new product line, a component your current chain can't quite deliver. And no appetite for changing suppliers mid-project. Carmo's engineers build manufacturability in from the first design review. The part then moves into your validation builds without leaving the building.
You're specifying on a client's behalf, so the lines have to be clean: their IP stays theirs, our process stays ours, and the engagement works direct or through your end-customer. NDA first, then engineering.

What Carmo's integrated setup delivers

At Carmo the team that sketches your component is the team that moulds it. In most programmes it passes from one supplier to the next, and every hand-over leaks time, understanding and judgement.

  • Days, not weeks: design, tooling and moulding iterate together, so what you test at prototype is what you ship at volume.
  • Your project keeps its memory: what you solved in week three is still solved at volume.
  • Design decisions by people who live with them: Carmo moulds its own products daily; that judgement shapes your part from the first sketch.

One team, around 85 people. Every step sits with them.

Carmo Print Moulding: our own hybrid of 3D printing and injection moulding

This is the step we invented: prototypes injection-moulded on 3D-printed tooling, in the same production material you ship.

  • Tools in days: design variants iterate in parallel.
  • Proven: EYE-GO went from concept to 20+ functional prototype variants in eight months, at 40–50% lower development cost.
  • Ours, not licensed: Carmo developed the process and prints the tooling in-house, so your part never waits on a third party.

The first part you hold is already the real thing.

Quality Assurance at Carmo

Quality, compliance, and your regulatory file

From validation builds onward, your project runs under Carmo’s ISO 13485-certified quality management system; design and development sit inside the certified scope. Medical-component assembly runs in a validated ISO Class 8 cleanroom.

As your component supplier, Carmo hands you the component-level traceability and audit-ready documentation your regulatory file needs.

Quality assurance: certifications, documentation and the certificate itself →

A dependable supplier for your device's regulated life

Medical-device programmes run for decades, and the supplier you qualify runs with them:

  • Stable and independent: privately held, Danish-owned since 1941; commitments that don’t escalate to a corporate parent.
  • Built to take on your programme: nearshoring from Denmark keeps the chain short; the 2018 expansion roughly doubled production space.
  • Lifecycle support: end-of-life copy tooling, material-change management and re-validation support are part of the engagement.

The supplier you qualify is the supplier you keep.

What this means for your scope-3 and your ESG file

Producing in Denmark is a deliberate choice, and the in-house control behind it gives you data you can use:

  • Component-level CO₂ data from Carmo’s ERP, for your own scope-3 reporting.
  • 60% of surplus production material recycled back into the supply chain.
  • Committed under the SBTi (certificate 40001785) to halve scope 1 and 2 emissions by 2030.

Detailed and documented numbers your ESG report can cite.

Frequently asked questions

What this is

What is Carmo's Engineering & Injection Moulding service?

One engineering team takes your component from first concept to regulated volume production: the same team at every phase. The real value is that people who run production every day shape the design early, where the decisions that drive cost, robustness and quality across your device’s life are actually made.

In-house, the engagement covers the whole chain:

  • engineering consultancy and material selection, from concept
  • tooling engineering
  • rapid prototyping in your production material (Carmo Print Moulding)
  • validation builds and 1K/2K/3K injection moulding
  • validated ISO Class 8 cleanroom assembly, automation and packaging
What engineering capabilities does Carmo bring beyond prototyping?

Design and Manufacturing Engineering is where the tradecraft lives. Carmo’s engineers carry decades of hard-earned production experience: running 1K/2K/3K injection moulding at volume, 3D-printing their own prototype tooling, operating ISO Class 8 cleanroom assembly day in, day out. That experience is what lets them spot design issues early and suggest tweaks that materially improve production output, lift quality, and lower component cost down the road, savings that compound across the regulated life of your device. The biggest payback lives in early design decisions: merging parts and features, leveraging 2K/3K moulding to reduce assembly steps and post-processing, designing components for the production environment they’ll live in.

Who engages Carmo's Engineering & Injection Moulding team?

Whether you’re a medtech startup founder, an established OEM introducing a new product, or a contract design firm working for a client, what you bring is a problem that needs production tradecraft to become a manufacturable component. Not a manufacturing slot for a finished spec, but engineering depth from the design stage. See the EYE-GO case for one such engagement.

Path to volume & quality

What is the difference between Carmo Print Moulding rapid prototyping and additive manufacturing for production?

The difference is what the prototype is made of, and how. Carmo Print Moulding uses 3D-printed tooling to mould your part in the same material you’ll produce in, so the prototype behaves like the real production part, not like a 3D print of it. That’s what lets you test fit, function and material before committing to a steel tool.

Additive manufacturing for production is a different job: the finished component is 3D-printed directly as the end-use part. It earns its place on short runs where a steel tool would never pay off, and Carmo uses it where it fits, sometimes alongside moulding in the same project.

Most medtech projects start in Carmo Print Moulding because of the path it puts you on: the same part and the same team, from that first functional prototype through to ISO 13485 volume production, so the process and the supplier stay the same as you scale up.

How does Carmo support the journey from concept through regulated volume production?

The people who design your part are the same people who run it at volume. Most of a component’s cost and risk are locked in early, before a tool is ever cut, and engineers who have spent years on the production floor design for what actually works at scale, not for what looks right on a drawing.

That one team stays with your project from concept through the prototype rounds, the validation builds under Carmo’s certified ISO 13485 quality system, and into regulated volume production. Because the work never changes hands, your supplier qualification, audit trail and documentation carry forward instead of restarting; your qualification holds as you scale up.

Is Carmo ISO 13485 certified?

Yes, continuously since 2013. Carmo has run a certified quality management system since 1993, and certified to ISO 13485 since 2013:

Carmo A/S's quality management system is certified to ISO 13485:2016 Medical devices quality management system by Bureau Veritas (accredited by DANAK), certificate no. DK020611. Scope: Design, development, manufacture and assembly of injection molded plastic components. Valid: 2. September 2026 – 1. September 2029.

All Carmo plastic components are manufactured under the same QMS and procedures.

Design and development sit inside that certified scope, not adjacent to it, so the engineering you engage at concept runs under the same QMS that governs your regulated volume production. Carmo is a component supplier; MDR legal-manufacturer responsibility rests with you as the OEM placing the finished device on the market.

Partnership & catalogue

Is Carmo a medical-device contract manufacturer?

Yes, for components. Carmo is a contract development and manufacturing partner for medical-device components (injection-moulded plastic components, valves, ports and assemblies), not a finished-device manufacturer. Its certified ISO 13485 scope is the design, development, manufacture and assembly of those components; the OEM placing the finished device on the market is the legal manufacturer under MDR (Regulation EU 2017/745). From first prototype through validation builds to regulated volume, your components are developed and produced by one engineering team, with no supplier handover at scale-up.

How does Carmo support medical-device supplier partnerships over the long term?

In medical devices, once you’ve qualified a supplier they’re part of your device for its whole regulated life. Carmo’s medical customer relationships run 20 to 30 years, with components still in continuous production, and the real question is whether that supplier will still be there, and still be the same company, two decades from now.

Carmo has been privately owned in Denmark since 1941, with production in Espergærde. That stability is the point: the company that qualifies your component today is the one still making it when your device is still on the market. And because the same team stays with the component across its life, the changes that inevitably come (a new material regulation, a worn tool that needs replacing, a re-validation) are handled inside your existing supplier qualification. You don’t re-qualify a supplier every few years. You keep the one you have.

What if we need a proven standard component rather than custom development?

Then start from the catalogue. Carmo’s medical-component catalogue includes drainage valves, filler valves, connectors, tube flanges, aeration eyelets, puncture ports, and hangers: proven designs in continuous production for medical bags, ID bracelets, and immobilisation equipment, produced under the certified ISO 13485 QMS. Carmo also runs a standard technical-component catalogue (HF-weldable eyelets, valves, threaded nozzles, snap grommets, drainage fittings) for industrial, maritime, agriculture, cleantech, and rescue applications. Custom variants of standard components are an established intermediate engagement: bring your specific geometry or material adjustment, and the engineering team scopes the variant from a known starting point, faster and lower-risk than full custom development. For full custom development from concept, including unique IP-protected platforms like the Carmo SuperValve™ family built on Carmo’s granted Cross Valve and Turnvalve patents, the larger custom development engagement above is the path.

Getting started

Does Carmo sign NDAs before scoping a development conversation?

Yes. Carmo signs a one-way non-disclosure agreement before scoping discussions that involve customer IP, clinical-context detail, or regulatory pathway specifics. A brief one-way NDA covers the scoping conversation; a mutual, project-specific agreement is settled at project start, before development work begins. Turnaround is typically days rather than weeks; contact [email protected] to start the exchange.

Where do I start a custom development project with Carmo?

Three entry points depending on what you have. If you have a concept but no design yet, bring the problem rather than the specification; Carmo’s design team can work from functional requirements through to a manufacturable component. If you have a design but want to test it in production material before tooling commit, Carmo Print Moulding delivers functional prototypes in days. If you have a component in field service and want to redesign it for cost, durability, or regulatory fit, the integrated team handles redesigns from existing components routinely. In all three cases, contact [email protected] or visit carmo.dk; a brief one-way NDA covers the scoping conversation.
