- High component strength: Robust fasteners are created through targeted forming and extrusion
- Economical series production: particularly cost-effective for medium and large quantities
- Versatile contour design: thanks to multi-stage cold forming, even complex geometries are possible
- Reduced post-processing: our tight manufacturing tolerances save time and costs
- Efficient process: resource-efficient approach with minimal use of energy and materials
- Material and cost savings: In many cases, by converting parts previously produced by machining to cold forming, we offer significant cost and price reductions through material savings and increased production speeds coupled with improved strength
Our manufacturing processes
As a specialist with decades of experience, we use various cold forming processes to optimally implement your specific requirements.
Controlled material deformation
Extrusion enables us to produce parts that require a higher degree of forming which is not possible with conventional cold forming, e.g. oversized heads and geometries compared to the shank.
We can also use cup extrusion to manufacture hollow parts that could previously only be produced by machining. This has the advantage that we can reduce costs through material savings and higher production speeds compared to turning.
Complex shapes can be realized
What is not possible with conventional 2-step pressing processes can be achieved with our modern 3-, 4-, 5- and 6-step presses, selected according to the complexity of the fasteners and other formed parts to be produced.
Post-processing formed parts without media discontinuity
In our in-house development department, our engineers develop all the tools required for cold forming and machining in order to achieve the best possible tool life and highest possible production speeds.
For special requirements, cold forming can be supplemented by machining processes such as turning, milling or thread cutting. These steps are carried out in our own machine park and enable the production of cold-formed special parts with specific features.
Sorting, checking, packing: ready for your place of use
Our parts pass through automatic testing and sorting systems. Characteristics such as length, diameter, roundness or thread depth and much more if required are checked using cameras and lasers. C-sorting ensures that only flawless components are further processed or delivered. They are then packaged – sorted, labeled or as a ready-to-install assembly.
Outgoing goods quality
In addition to our strict process control, no product leaves our premises without being checked and recorded for all dimensions, tolerances, mechanical properties and even appearance requirements. In this way, we ensure that our customers only receive parts that fully comply with the specifications.
Thanks to our own laboratory, we are able to use any measurement technology – from projector, contracer, hardness and tensile tests to automated optical inspection.
Individual test plans are drawn up for each product, in which not only all tolerances, mechanical properties and appearance requirements are defined, but also the specification of the tests that are carried out before release and delivery to our customers.
PPAP according to IATF 16949
As an IATF 16949-certified company, we offer PPAP, a professional production part approval process for sampling series parts. For product and process approval, we provide the required measurement, material and functional reports on standardized forms – also paperless – and ensure an efficient exchange in the approval process.
100 % control through optical sorting
In many cases and in today’s automated assembly lines, 100% inspection has become the norm to ensure that parts are delivered close to “zero ppm”. To achieve this, state-of-the-art automated inspection machines are required.
With a variety of optical inspection machines and even eddy current machines for testing internal cracks and hardness, we can deliver parts that are 100% inspected. Our machines inspect every single part with a throughput of up to 500 pieces/minute to enable high volume inspection.
Mechanical tests
An extensive range of equipment is available for testing the mechanical load-bearing capacity, with which the physical product properties such as tensile strength, torque and hardness are tested. The testing department also serves as a laboratory for the in-house development of product variants, e.g. for optimized Standard screws with increased strength.
Precision down to the µ
To ensure dimensional accuracy, we use state-of-the-art measuring methods, including a Mitutoyo Contracer for high-precision contour measurement, camera systems and digital projectors that check up to 500 parts per minute with 20 µ accuracy. This enables us to meet the required product quality, which benefits your production reliability.
Sustainable quality
Our experience with materials and expertise in surface treatment results in connecting parts with a perfect balance of application, resistance and cost-effectiveness. A test laboratory with chemical-physical testing equipment is available for this purpose, including a salt spray system, which provides information on corrosion resistance and gives us a significant competitive edge, e.g. in the offshore industry.
Certified quality
Our quality management is certified in accordance with ISO 9001 and IATF 16949. In addition, we meet and exceed many industry and company specifications.
Tested quality
You can rely on itOur quality assurance is internationally certified (IATF 16949 and other certifications) and accompanies all work steps. Complete traceability back to the primary material is standard. Our testing processes ensure reliable component quality.
Frequently asked questions – we are happy to answer
We process various materials: stainless steels, aluminum, copper alloys, steels including high-strength steels – most materials can be processed using our methods. The optimum choice of material depends on factors such as strength and corrosion resistance.
Normally from approx. 10,000 units. The higher the quantity, the lower the unit production costs. We will advise you individually on the most economical solution.
Yes, absolutely! Our multi-stage cold forming processes and our in-house toolmaking department also enable complex geometries – also in combination with post-processing.
