At GRUEBER, technical progress has a long tradition. Because our aspiration is to act as a driving force, we continuously and proactively develop new possibilities for optimisation. To do so, we are always looking for new materials, surface treatments, production processes and machinery solutions as well as testing and inspection devices.
The benefit: we provide support for our customers, even if there are complex questions and challenges to master on the way to innovation. This is how we bring ourselves dynamically into our customers’ development processes and make contributions toward pioneering products and solutions.
In our cooperation with our customers, we see ourselves as consultants, developers, manufacturers and partners. We like to be involved early on in development projects and provide ideas that contribute to better overall solutions. Here we look beyond the horizon and design our products, down to each detail, so that they provide the maximum technical and economic benefits.
Because our services have been proven in practice, we offer our customers the best possible support, above and beyond our products. This means that our actions are quick and reliable and that we are there for our customers, actively involved. This extends into logistics concepts with which we deliver just in time and adjust to customer processes in development and production.
Selecting the right material is particularly important for the trouble-free, long-term function of our springs and bent parts. In terms of their product design, our customers benefit from the extensive materials expertise of our designers and engineers. The material used is customised for the respective application.
Moreover, we rely on quality suppliers, who always provide us with high-quality materials that meet standard requirements. Of course, we inspect all material deliveries before we use the material in production. To ensure material quality, we use defined processes: provision of primary materials with acceptance test certificate, quality check at receiving, continuously updated supplier evaluation.
We make GRUEBER products at our Hagen-Kabel location. They are completely “Made in Germany”. With lean processes and state-of-the-art machinery, we combine speed with the highest degree of precision. In this way, we can quickly supply a level of quality that absolutely guarantees reliability and safety. We implement the GRUEBER quality idea along the entire value chain using a quality management system certified in accordance with DIN EN ISO 9001:2008.
In addition to technology, processes and quality management, above all it is our employees that make the difference. They are highly specialised in everything to do with spring production. It is important to us to require all employees use their talents and capabilities and to provide support for them. To do this, we rely on continual training and advanced education. This forms the basis for a high degree of motivation as the foundation for the production of extraordinary products.
In daily use, GRUEBER springs and bent parts are often exposed to harsh weather and environmental conditions. So that the products function safely and reliably over the long term, we use various surface treatments to ensure high-quality protection. Most important here: liquid coating with water-based products and powder coating, including pre-treatment with zinc-manganese phosphating. Our company offers both processes in-house.
Of course, we are happy to customise the surfaces based on other customer requirements. In this case, we work together with various partners, with whom we do many additional surface treatments. For new requests, we enjoy developing new, appropriate solutions in cooperation with our partners. By request, we label products using colour coding, pad printing, manufacturer labelling, labelling strips or labels.
The idea of quality is one of the solid roots of the modern, yet traditional GRUEBER company. Everything is oriented toward offering the best quality products and services. To ensure that quality is not a coincidence, we have embedded our quality management system, certified in accordance with DIN EN ISO 9001:2008, deeply into all processes and company areas. In this way, we can implement and supply quality down to the finest detail.
At GRUEBER, there’s a method to quality. We do not rest in our achievements; instead, we continue to develop our quality assurance. For example, we believe in advanced training and qualification for our employees. In addition, we used advanced quality testing stands to check the quality of our products. In this way, we can continually carry out service life testing on our response spring testing stand or endurance testing stand.
