- Household appliances: functional panels, covers, carrier parts
Our toolmaking - precision begins in the detail
Our vertical integration is your competitive advantage.
Because our in-house toolmaking enables short reaction times, maximum flexibility and absolute control over every detail.
This is where progressive tools are created that not only work precisely, but also meet the highest quality standards.
Special features:
- CAD-supported design with simulations
- High-speed milling centers and wire erosion
- Integrated maintenance & servicing
- Digital tool management for traceability
Process integration - from the idea to series production
The use of progressive tools is only economical if the tool, machine and material form a single unit. That is why we support you from the initial idea through to series production - with an integrated engineering approach.
- Feasibility studies and FEM simulations
- Prototype construction and pre-series production
- Series transfer including process validation
Quality as a success factor - leaving nothing to chance
Quality is not a product of chance. That's why every process step in our tool and parts production is certified according to DIN EN ISO 9001 certified. In addition to statistical testing methods, we rely on camera-based full inspections - for documented zero-defect targets.
Why work with us? Function meets manufacturing expertise
We are convinced that tools don't just have to work - they have to create added value.
That is why we consistently develop our progressive tools in line with the requirements of your components.
We analyze the functionality, evaluate material properties and consider ease of maintenance and service life right from the design phase.
Because only a tool that fits the process perfectly can work economically in the long term.

- In-house tool design & production
- Short delivery times thanks to in-house production
- Flexible customization through modular systems
- Technical support over the entire product life cycle
- Experience from over 25 years of series production
What are progressive dies -
and why are they so important?
When it comes to economically producing complex components in large quantities from strip material, progressive tools are the first choice. These are specially developed tools that combine several processing steps - such as punching, bending, drawing or embossing - in a continuous process. The material passes through various stations in the tool, with a defined work step taking place at each position.
These tools are true all-rounders, as they combine maximum precision, repeat accuracy and speed in a single production process. The result: stable components of consistent quality - with minimal waste and optimum use of resources.
Variety of materials - tailored to your requirements
Our progressive tools process a wide range of metallic materials - precisely adapted to your application. We take mechanical properties, coatings and forming behavior into account as early as the tool development stage.
Common materials:
- Spring steel
- Stainless steel
- Aluminum
- Copper
- Brass
- Bronze
Pre-galvanized, selectively coated or pre-finished on request.

More informationFrequently asked questions about progressive tools
What factors determine the service life of a progressive die in series production?
The service life depends largely on the choice of material for active components (e.g. powder metallurgical steel vs. carbide), service life optimization through coatings (PVD, CVD) and the maintenance strategy. Another key point is the design in terms of force distribution, thermal load and guide play. Regular inspections and wear monitoring using sensor technology increase transparency and significantly extend the productive service life.
How do complex forming geometries affect tool design?
Complex geometries lead to increased installation space requirements in the tool and influence the number of steps as well as the die and cutting edge arrangement. In order to avoid tool breakage, forces must be analysed in advance using FEM simulations and optimized using suitable punch supports, punch guides or extrusion contours. An intelligent step division can reduce forming stresses and increase process stability.
When does it make sense to use a modular progressive die?
Modular tools are particularly worthwhile for variant production, reduced development time or high maintenance requirements. Individual assemblies - such as cutting inserts or guide units - can be removed and replaced separately. This reduces downtimes and enables the targeted regrinding of individual elements. This flexibility is a decisive advantage, particularly for series adaptations or platform parts in the automotive sector.
What options are there for integrated quality assurance in the tool itself?
Modern progressive tools can be equipped with tactile and optical sensors. These record pressing forces, belt feed, component positioning and tool wear in real time. Camera systems even enable 100% inspection directly in the process. Incremental displacement measuring systems for bending angle detection or laser sensors for height control can also be integrated - which is extremely important, especially for safety-relevant parts.
How do strip material tolerances influence the tool design?
Variations in width, thickness and strength in the strip material have a direct effect on the forming behavior and the cutting edge load. Even small deviations can lead to dimensional deviations in the end product or cause excessive tool wear. For this reason, it makes sense to compensate for this in the design by means of clearances, slides, hold-down pressure or even adaptive strip centering - especially for high-precision progressive tools.
Are there any restrictions on the use of progressive tools for high-strength materials?
Yes - high-strength and ultra-high-strength steels (e.g. DP, CP, martensite) place significantly higher demands on the tool design. Cutting gaps, tool hardness and coating must be precisely matched, as the forming forces are significantly higher. Without suitable lubrication and precise process control, edge fractures or micro-chipping can occur. The machine frame must also be able to withstand these loads - servo-electric presses are often an advantage.
