Precision Turned Parts for Automotive and Mobility
Behind millions of vehicles that run reliably, there is often an unassuming precision turned part. Safety-critical and function-critical components of precisely this kind are what we have been manufacturing for the automotive industry for over 30 years, reproducibly, traceably and in accordance with IATF 16949.
IATF 16949 · ISO 9001 · ISO 14001 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. IATF 16949/ ISO 9001 / ISO 14001 / ISO 13485 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 conventional drivetrain technology through to electric mobility, 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, though 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
Exhaust technology
Turned parts for injection systems, valves and exhaust aftertreatment components. High-temperature-resistant materials and tight tolerances for repeatable dosing accuracy under fluctuating thermal conditions.
Electric mobility and drivetrain
Precision turned parts for electric drives, charging infrastructure and thermal management systems: shafts, bushings and core elements for braking systems, and components for coolant pumps in battery and drivetrain thermal management.
Braking and steering systems
Precision turned parts for brake components, where functional reliability throughout the vehicle lifetime is not optional but a fundamental requirement. Demanding specifications for dimensional accuracy, surface quality and material certification.
Transmission technology
Shafts, bushings and solenoid valves for manual and automatic transmissions. Tight tolerances and high surface quality as decisive factors for service life and noise behaviour.
Connectors and infotainment
Contact pins and contact sockets for connectors in vehicle electronics. Specialist turned parts for infotainment systems. High demands on contact quality, feedability for automated assembly and environmental resistance throughout the vehicle lifecycle.
What Sets Us Apart As Your Manufacturing Partner
In the automotive industry, precision turned parts form part of a system that must perform reliably over years and across millions of vehicles. A component in a braking system, a shaft in an electric drivetrain, a contact part in a connector: each of these must function dependably throughout the entire vehicle lifetime, under fluctuating temperatures, vibration and mechanical load.
We have been supplying the automotive industry for over 30 years. Our precision turned parts meet all relevant requirements, from conventional drivetrains through to electric mobility. With IATF 16949 certified processes and CAQ-supported quality assurance, we maintain high volumes without sacrificing consistency. All parts are manufactured in compliance with PPAP requirements and subject to SPC monitoring.
What matters most to our customers
Zero defects in high-volume series
A single faulty part can bring an assembly line to a standstill or trigger a product recall. The costs bear no relation to the price of the part.
IATF 16949 as a mandatory requirement
Without an IATF 16949 certified supplier, there is no supplier qualification — and that applies at Tier 1 level and increasingly at Tier 2 as well. The certificate alone is not sufficient: what matters is how FMEA, MSA and SPC are applied in day-to-day operations.
Technical cleanliness
Hydraulic, brake and injection components are subject to defined particle limits. Cleanliness is a product requirement, not something that can be taken for granted.
Supply chain security
Raw material, tooling or capacity shortfalls hit the line directly. Buffer stock and short decision-making paths are worth considerably more than well-intentioned promises.
Engineering input from the outset
Changes made after drawing release cost a multiple of what could have been resolved in an early conversation.
Documentation that withstands audits
PPAP, IMDS, first article inspection report, SPC evidence — not available on request, but provided as standard.
E-mobility is changing the requirements
New drive concepts bring new materials, new geometries and new tolerance requirements. A manufacturing partner who understands this shift saves iterations.
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.
Materials expertise for high-volume production
Free-cutting steel, stainless steel, aluminium and lead-free materials are processed with complete material certificates, the foundation of every traceability record and every IMDS entry.
Validated processes for high-volume series
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. In the automotive industry, that means we measure what we promise and document what we measure. This is underpinned by our IATF 16949 certification, which makes the connection between error prevention, process control and documentation binding rather than optional.
Every batch, every component and every process step passes through clearly defined control stages. From prototype through to high-volume series, you can rely on reproducible, audit-ready results at every stage.
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.
