MEDICAL AND LABORATORY TECHNOLOGY
Precision Turned Parts for Medical and Laboratory Technology
Precision turned parts for medical, laboratory and diagnostic systems.
Materials with documented provenance and batch traceability, validated processes and complete traceability. From prototype to series production.
ISO 13485 · ISO 9001 · ISO 14001 · IATF 16949 certified
Made in Switzerland ·· 80+ Years of Experience
Our machinery is built for precision, and our processes make sure it stays that way. Every part that leaves our factory goes through exactly the same checks, whether it’s a prototype or the ten-thousandth piece off the line. ISO 9001 / ISO 14001 / ISO 13485 / IATF 16949 certification isn’t a framed certificate on the wall for us. It means CAQ-driven inspection and watertight documentation, so every batch holds the same standard as the very first approved sample.
Where Our Parts Work Every Day
From medical technology through to laboratory diagnostics, we cover a broad range of applications, each with its own requirements for material, tolerance and surface finish. The overview below sets out typical fields of application, although not every requirement can be captured in a product description. If you are unsure whether your component is a fit for us, please give us a call.
Our Application Range
Diagnostics, analytical instruments and laboratory technology
Fluid-handling components, pump parts, sensor housings, guide bushings and drive elements for infusion and injection devices or laboratory automation systems. Demanding requirements for dimensional accuracy, surface cleanliness and chemical resistance.
Pump systems and fluidics
Precision turned parts for dosing pumps, micropumps and valve systems in medical and laboratory technology. Tight tolerances for repeatable dosing accuracy, with media resistance as a key design criterion.
What Sets Us Apart As Your Manufacturing Partner
In medical and laboratory technology, precision turned parts are not simply components, they form part of a regulated system. Manufacturing components for infusion, injection or analytical instruments calls for validated processes and places considerable demands on traceability.
We manufacture precision turned parts for medical and laboratory technology that meet all of these requirements. As an ISO 13485 certified business, validated processes, IQ/OQ/PQ qualification, complete traceability and full quality documentation are part of our everyday quality system.
With our versatile machine base of conventional, CNC and multi-spindle technology together with rotary transfer machines, we manufacture precision turned parts for medical and laboratory technology economically, from prototype through to high-volume series
What you can rely on
ISO 13485: a quality system for medical devices
Our ISO 13485 certified processes ensure validated manufacturing procedures, extended documentation and complete traceability for regulated products.
Complete traceability
Complete traceability means that for every batch produced, we hold the raw material certificate (including heat number and standard), production parameters, machine identification, date, inspection results and despatch records. These records remain available for the legally required retention period.
Materials with documented provenance and batch certification
We work with materials that are suitable and proven for medical technology applications. Material certificates including heat number and batch certification are available for every material we use.
Cleanliness and packaging
Cleanliness is a product requirement in medical technology, not something that can be taken for granted. Particle-free finishing, burr-free edges and defined cleaning processes following machining are built into our quality planning.
Optical and tactile metrology
Three-dimensional coordinate measuring machines for repeatable inspection results on complex geometries. Optical measuring systems for non-contact inspection of delicate components and surfaces. Tactile measurement for fitted diameters and form tolerances. All measuring equipment is subject to a defined calibration schedule, the foundation of any audit-ready inspection record.
Co-engineering and development support
As a development partner, we support projects from the concept stage onwards: reviewing tolerance specifications for feasibility, assessing materials, and optimising geometries for stable series production.
Precision Manufacturing. Made in Switzerland.
Made in Switzerland means more to us than the highest technical standards alone. It also stands for a personal, collaborative relationship with our customers and a strong record of on-time delivery, something our customers tell us time and again.
Validated processes
IQ/OQ/PQ-qualified manufacturing steps ensure that every component is produced under the same controlled conditions, traceable and audit-ready.
Complete traceability
Every batch is fully documented in terms of raw material, production parameters and inspection results, throughout the entire legally required retention period.
Consistent quality across every batch
Stable, CAQ-supported processes and statistical process control ensure that the batch produced in two years’ time is every bit as reliable as the first.
Co-Engineering from Day One
We bring our manufacturing knowledge directly into your development process. That typically eliminates secondary operations, locks in process stability and drives down unit costs.
Short Response Times & Direct Decision-Making
With our own raw material warehouse, we can react quickly when delivery quantities or schedules change.
Everything from a Single Source
From turning and finishing to assembly and quality documentation, we coordinate everything.
Precision as our Attitude. Quality is our Standard.
Quality, to us, is not merely an inspection step, it runs through everything we do. We measure what we promise, and we document what we measure. This is underpinned by our ISO 13485 certification, which makes that link between control, validation and documentation binding rather than optional. As a result, you can rely on repeatable, audit-ready outcomes at every stage, from prototype through first article approval to ongoing series production.
Our measurement capabilities span tactile and optical methods, contour measurement and high-precision 3D coordinate metrology. Surface finish, geometry and positional tolerances are all checked at defined intervals under real production conditions. Every step is monitored using statistical process control.

Conventional and CNC long-turning, CNC short turning, multi-spindle turning and rotary transfer machines. In-house, this is supplemented by centreless grinding, honing, vibratory finishing and roller burnishing. Surface treatments such as electropolishing or electroplating are carried out via qualified partner companies.
Are you ISO 13485 certified, and what does this mean for our collaboration?
Yes. For manufacturers of medical devices, a supplier’s ISO 13485 certification is no longer optional, it is a prerequisite for supplier qualification.
What tolerances are achievable with CNC turned parts for medical technology?
We routinely manufacture in the hundredths or thousandths of a millimetre. With appropriate requirements, suitable design, and the right material, these tight tolerances are achievable. In the initial consultation, we discuss together what makes technical sense and is economically feasible for your application.
Can your components be assembled automatically?
Yes, that’s by design. We engineer our components to be assembly-ready from the outset. Feed compatibility, pick-and-place suitability and compatibility with automated assembly equipment are topics we raise in the very first development conversation.
Do you handle prototypes and small series as well?
Yes, provided the intention is to scale to medium or larger volumes. For projects that are purely prototypes or very limited runs, we can support you through our partner network where needed. Otherwise, we follow projects all the way from first drawings through pre-production samples to full series manufacturing and we’re at our most useful when we’re involved from the start.
What surface finishes can you offer?
In-house, we offer centreless grinding, honing, roller burnishing, vibratory finishing, and hobbing. We refine your turned parts to micron precision. For processes we do not offer ourselves, we handle the complete coordination including quality control.
How do you ensure process reliability and series stability?
Our manufacturing processes are ISO 9001 certified and CAQ-supported. Every series runs with defined, validated process parameters that are fully documented. Through statistical process control, 3D metrology, and complete batch traceability, we ensure that Batch 1 and Batch 500 are identical. Zero-defect tolerance is not a slogan, it is a concrete goal of our series processes.
Do you offer co-engineering for medical components?
Yes, and it’s one of our strongest offerings. Get us involved early and we can work with you to optimise tolerances, materials and geometries together. The result is typically a better part, a simpler process and lower unit costs.
What delivery times and logistics concepts do you offer?
Thanks to our own raw material warehouse, we respond flexibly to changes in demand. We offer VMI warehouse concepts, safety stock, and flexible batch size adjustments. As a Swiss precision parts manufacturer with direct decision-making channels, our response times are short and you always have a direct contact person.
