Our services

Our production is entirely based on customer requirements. Customised manufacturing for even the smallest quantities, careful designs and express deliveries are our strengths.

Our process

Quality without compromise

All our articles are subject to the strictest inspection requirements – from raw material acceptance to dispatch.
Our raw material deliveries arrive with supplementary sheet or certificate and are assigned a material number on acceptance to ensure unambiguous identification.
The initial sample/production test is specified on our internal working papers, and must be declared executed with date and signature.
The inspection interval for the series is stipulated by the customer or Quality Management, and equally documented on the job card.
The final inspection is carried out either in accordance with the internal “Sampling plan for final inspection” based on AQL table 7.1 or as specified by the customer.
Upon customer request, the collected final inspection data is documented by means of electronic measuring tools and the “Sample analysis QS-STAT” (official automotive supplier programme) pursuant to EN 10204.2.1.

Each of these points guarantees full traceability of our products.

Engineering

We are happy to advise you – in terms of design, material selection and your feasibility study. We carry out corresponding spring calculations and tests in accordance with your specifications, or produce articles based on your technical specifications, draft or sample.

Production

We employ state-of-the-art production engineering to turn plain wire into bent wire parts. Primarily, we utilise he technology of the market leader Wafios AG with whom we enjoy a close and fair business relationship, enabling us to guarantee an equally high quality standard.

Final inspection

Unless defined otherwise, the final inspection shall be based on DIN AQL1.5 and carried out by means of digital measuring projector, all types of callipers and sometimes servo-controlled spring testing scales. The data determined in the process can be documented with the official QS-STAT automotive supplier programme in digital or paper form on request. All measurement tools are subject to strict test instrument monitoring periodically carried out to around 80% by an external, accredited provider.

Traditional springs

We also do run-of-the-mill products. Of course, we can also offer you regular standard springs like compression springs, tension springs, leg springs, coil springs, torsion springs, leaf springs, spiral leaf springs, torsion bars, etc. Since we exclusively produce customised products, we have no actual standard spring or standard range. Instead, we offer cost-efficient production of any type of spring within record time.

Custom orders

We put the spring back in your step! Bounce off our 70 years of experience in difficult times and take advantage of our comprehensive support. We are happy to advise you on possible solutions to your problem and visit your facility to discuss approaches, optimisation and feasibility right where the object in question is located.

Promotional items

Your idea – our challenge! Wires make for countless potential small promotional items and original giveaways for customers and prospects at trade fairs, meetings and events. We realise your ideas for your company. We are happy to get you started with suggestions and support your design and planning. Benefit from our solid in-house experience in design and production technology!

Express orders

Often produced faster than the order is signed off! Sized for flexibility, staffed with motivated personnel and equipped with the latest machining tools, state-of-the-art machinery and a substantial raw material store for the most popular material qualities, our company is able to offer an express service without equal. Your components are ready for dispatch within one to three days.

Prototyping

Cost-effective test parts at short notice. In our experience, time is of the essence when a prototype is needed. Thanks to our state-of-the-art machinery, we are happy to produce high-quality prototypes at short notice and without incurring tooling costs, especially for wire thicknesses ranging from 0.10 to 13.00 mm. Since 100% of our production is in-house, engineers and developers are welcome to attend when we set up the production machinery, allowing us to integrate any corrections or adjustments they may request directly in the programming.

Finishing

All show with great substance! The optical surface of a component decides within a second whether we see something as “beautiful and precious” or “unattractive and raw”. While appearance is secondary in most fields of application for a spring, especially when the component disappears inside a machine or mechanism, there is more to quality than meets the eye. DH/SH grade spring steel and spring steel strip are commonly used in spring production. These materials are often prone to rust – which is easy to minimise or even eliminate with appropriate surface treatments, such as burnishing, galvanising, passivating, chrome-plating, etc. Through our competent partners, we offer all common surface treatments, allowing you to source your components/spring elements ready for action directly from us without having to shop around.

Washing system

In the summer of 2019, we replaced our outdated PER washing plant that still used perchloroethylene for degreasing with a water-based system featuring excellent environmental performance. A special, additional rinsing procedure with amplified spray nozzles achieves utmost surface cleanliness. Following our production process, this prepares our articles optimally for the next steps, before a thorough final cleaning with anti-corrosive additives rounds the item off.
