Carmo has 60 years of experience in production automation

Scalable production: low volume injection moulding

From the first parts to millions a year. Start where your numbers are. Carmo moves with you.

In short: Carmo scales a component from low-volume injection moulding to high-volume serial production: a low-capex start on a steel tool with one or two cavities and a robot-assisted cell, then more cavities and full automation as your numbers grow.

From the first part to serial production, one route

The quantity picks the technology; the team stays the same:

  • Below the smallest series: parts produced additively, switched to a tool when the volume justifies it
  • Prototypes, pilot and bridge runs: a 3D-printed tool (Carmo Print Moulding), functional parts in your production material in days
  • Into production without the capex: a steel tool or a soft tool, with one or two cavities and a robot-assisted, semi-manual cell for printing and assembly

Every switch is planned from day one, so the process change is scoped before it is needed.

Scale-up path: 3D print, Carmo Print Moulding, aluminium tools, injection moulding pilot production, first-generation volume, high volume

What changes as your volumes grow

Each step trades a larger investment and a longer lead time for lower unit cost and higher output:

When the launch date will not wait, market entry can start under an agreed interim control strategy, with tightened inspection and limited batch releases while the full IQ/OQ/PQ completes.

Start producing before the volume is there

Few products need a sixteen-cavity tool on day one. They need parts, documented, at a cost that matches the volume:

  • Steel, but one or two cavities: the production tool and the validated process, at a fraction of the capex of a multi-cavity tool
  • A cell built by our own robotics engineers: a collaborative robot moves the part to a turntable for printing and on to a jig for assembly, semi-manual, at minimal cost compared with a fully automated setup
  • When demand grows: a higher-cavity tool and fully automated hand-off to printing and assembly, on the same cells, by the same team

The capacity behind it

Your production runs on our own machines and cells, with automation built around your component rather than bought as generic line equipment:

  • 30+ injection moulding machines, 25 to 250 tonnes
  • Six-axis robots on most cells, grippers designed in-house
  • Automation both ways: fully automated cells for volume; cobot-assisted cells for a low-volume start
  • ISO Class 8 cleanroom environment for medical components
  • Room to grow: the 2018 expansion added 1,000 m² of production and 200 m² of cleanroom, roughly doubling the footprint to about 2,000 m²

The Carmo engineering team

The same team from first part to serial production

Your project does not change hands at the scale-up boundary: one engineering team carries a component from concept to regulated volume production. The engineers who prototyped the part specify its tool, run the validation builds and produce it at volume:

  • Supplier qualification extends, it does not restart: the certified ISO 13485 QMS engages at the validation builds and continues through regulated volume
  • Projects at different stages, one counterpart: one in development on Carmo Print Moulding, one in volume, one in redesign
  • Used to the long run: our own fluid-bag ports, valves and HF-weldable eyelets have been in continuous production for decades
  • Lifecycle work is routine: tooling wear, material phase-outs and design revisions, handled by the same team
  • From moulding to delivery: pad printing & assembly, inspection and component packing in-line

“With our injection moulding machines, robotics and AM technology we have the technology, experience and know-how to find smart solutions. We are ready for your next project, no matter the size.”

Frequently asked questions

Volume range

What production volumes can Carmo handle?

From single-digit functional prototypes through small-series validation builds and into full regulated volume production at several millions of parts per year, all with the same engineering team. Carmo runs more than 30 modern injection moulding machines with clamping forces from 25 to 250 tonnes, supported by in-house prototyping, automation and robotics, and validated ISO Class 8 cleanroom assembly for medical applications.

How does Carmo handle small-series production economically?

Three routes cover it. Carmo Print Moulding handles development-phase and bridge volumes in production material without committing to steel tooling, economic where lifetime volumes don’t justify a full tool. A steel tool with one or two cavities and a cobot-assisted cell starts ongoing production at low volume, at a fraction of the capex of a multi-cavity tool. And multi-cavity tooling with automated cells carries high volume across the 25-to-250-tonne machine range. The integrated design and tooling teams help you choose the route during scoping; the smallest quantities can be produced additively before any tool exists.

Scale-up & continuity

What happens when a project outgrows small-series production?

Your project doesn’t change hands at the scale-up boundary. The transition from small-series to full volume happens with the same engineering team. Carmo Print Moulding tooling for prototype and bridge volumes transitions to definitive injection-moulding tools designed by the same team; once your project enters validation builds and volume production, the certified ISO 13485 QMS engages and continues through regulated volume. Your supplier qualification, audit trail, and documentation extend rather than restart at the validation-build boundary. A tooling step-up (added cavities or a new tool) runs through documented change control and its own IQ/OQ/PQ before parts ship.

How fast can Carmo ramp up production on a new project?

Ramp speed depends on tooling status and material lead times rather than on team availability. Specific timelines settled during scoping.

Show all 9 questions
Can Carmo start supplying before the production process is fully validated?

Yes, under controlled conditions agreed with your quality function. When a launch date is under pressure, supply can start while validation completes: the trade-offs are weighed together (bridge production on an interim tool, or early runs on the definitive tool with tightened inspection and limited batch releases), every deviation is risk-assessed, documented and agreed before parts ship, and the full IQ/OQ/PQ completes in parallel. Carmo has supported launches this way several times; it takes close cooperation, regulatory know-how and a team that can sprint inside the ISO 13485 QMS.

Capacity & flexibility

Does Carmo have enough capacity for new projects?

Yes. The machine fleet (more than 30 modern injection moulding machines, 25 to 250 tonne range) plus in-house prototyping, automation, and cleanroom assembly carry meaningful headroom for new project intake. Capacity planning is part of the scoping discussion; you get a clear view of available machine time before committing.

What flexibility does Carmo offer between projects?

Flexibility comes from the integrated setup. If you have multiple projects at different lifecycle stages (one in development on Carmo Print Moulding, one in volume production, one in redesign), you deal with the same engineering team for all of them, and the same certified QMS governs each project from validation builds onward. The cost of moving a project between Carmo Print Moulding and definitive tooling (or back, for late-stage variants) is meaningfully lower than the equivalent supplier-switch cost would be.

How does Carmo balance automation with flexibility?

Automation cells are designed around your components rather than as generic line equipment, so they can be reconfigured if the component changes. Most injection moulding cells are equipped with highly versatile 6-axis robots, and in-house design of advanced grippers gives high flexibility and responsiveness when variants or new launches need to come online quickly. Robotics in cleanroom assembly supports process repeatability without locking the line to a single product: automation-grade throughput on stable products, fast reconfiguration on variants and new launches, all under one engineering function.

Scope

Does Carmo offer post-processing and packaging, or only moulding?

Both. Downstream assembly, inspection, printing, and packaging happen in ISO Class 8 cleanrooms alongside moulding, all under the certified ISO 13485 QMS. A component can move from raw material through final packaged form without leaving Carmo or its quality system, useful both for medical regulatory documentation and for shortening your logistics chain.
