We define a deep-drawn part based on our customer’s requirements concerning the part’s function and installation position within the overall assembly. These requirements flow into the component specification (e.g. materials, physical-technical characteristics, geometry and surface properties).

However, it is advisable to consider the specific conditions of the deep drawing process and discuss them with the customer even before preparing the final drawing and defining the final specification. These conditions include the wall thickness distribution, cold hardening, the surface structure, as well as radii and edges. Designing a part “suitable for deep drawing” not only helps to ensure its technical function; it is also beneficial for the overall manufacturing process and helps to ensure the process reliability – and thus also the economic efficiency – of the whole product.

Furthermore, it is essential to clarify contiguous topics at the very beginning of the “creation process” – such as measurement and testing procedures, parts cleaning and post-processing, as well as transport and packing instructions.

High cycle rates, relatively low material usage and a favorable strength/wall thickness ratio thanks to process-inherent cold hardening: All of these are compelling reasons why deep drawing is a manufacturing method which provides substantial benefits in terms of a component’s function, quality and economic efficiency.
With regard to economic efficiency, components manufactured with this method are far superior to others requiring metal-cutting machining.

All the tools and devices are designed and manufactured by our in-house teams. Our colleagues from Project Management, Design, Tool Making, Production and Quality Management create the tool concept as a design basis developed in close cooperation with each other.

Based on our more than 100 years of experience and our rich tradition of deep drawing, we have developed a precious knowledge database over the course of several decades. Today, not only our in-house teams, but also all our customers can benefit from this wealth of knowledge. By mastering the challenges of new projects we continuously broaden our horizons in terms of materials, technology, procedures and measurement technology.
For us, innovation is not just an empty word – we practice what we preach!
The documented know-how flows into the design of all the tools required for new projects. Our designers have already worked with proven and up-to-date 3D CAD software from SOLIDWORKS for many years.
Every project is centrally coordinated by the Project Manager, who remains the “patron” of the project over its entire life cycle.

Complex, multi-stage, high-quality tools are required for the series production of precise deep-drawn parts made from sheet metal materials. The series tool must be set up “unerringly accurately” in order to minimize risk and avoid subsequent time- and cost-intensive tool changes or even the need for reconstruction from scratch. Since saving costs and time is crucial for our customers, development risks and restarts must be avoided to the greatest extent possible. The speedy availability of near-series parts is playing a major role in this context.

In many cases, metal-cutting-machined or rapid-prototyping-machined sample parts, which we can provide at cost-efficient rates on a short term basis, are sufficient to examine fitting conditions and geometrical aspects.

Since sheet metal deep drawing alters the material properties (cold hardening) and surface structure, turned, milled or sintered sample parts are often not conclusive. In many cases they differ significantly with regard to the material and surface properties of serial parts. This means that no evidence of the component’s suitability for subsequent “real-time operation” can therefore be provided.

We provide our customers with near-series sample parts made with deep drawing tooling systems in close cooperation with a local partner. The samples more or less correspond to the serial parts as far as their material, mechanical and geometrical properties and their surface finish quality are concerned. During the course of the sampling process we already identify possibilities for optimizing both the component itself and the forming process in close cooperation with our customer.
This allows for testing the shape and function of the deep-drawn parts in mounted state and making further modifications as required – at a comparably low cost and within a relatively short period of time.

Our in-house tool making team manufactures all the tools for production on transfer presses and in progressive die processes. The individual tool components – such as stamps, rings and blank holders – are pre-manufactured and adjusted by means of turning, milling, grinding, eroding, hardening and coating if required. The assembly of transfer sets and modules, consisting of a large number of individual elements, is followed by testing and fine adjustment on the testing press or the production machine.

We take great pride in our Toolmaking team of experienced and committed, long-standing colleagues and motivated young talents. Based on our in-depth tool design know-how, young tool makers receive qualified vocational training in our Toolmaking department.

Depending on wear and tear and the service life of the individual active tools we specifically manufacture spare parts in order to reduce any subsequent manufacturing downtimes to a minimum. In the case of breakage or fatigue we replace the defective component with a spare part. This enables us to continue manufacturing immediately after release. Wherever possible, we replace tool components as a preventive measure if required. After every manufacturing order we clean, inspect and, if necessary, repair our tools before putting them back into storage.

Our in-house teams take care of the continuous inspection, maintenance and optimization of all our tools, with a clear focus on precision, flexibility and speed.

Deep-drawn parts and components “Made in Germany” go reliably and on-time from Bamberg to all corners of the world – wherever our customers need them.
