While in small series production the production steps:

Cutting | Edges | Bend | Deep drawing

are carried out with different machines, in large series these steps are carried out in punching and forming tools.

This method of production is significantly cheaper for large series.

Our tools

Punching tools mainly consist of three components: the punch, the die and the stripper. Economical production requires high-quality punching tools that are easy to assemble, require little maintenance and increase press productivity.

These tools form the technical basis for punching as a separating process and have high requirements in terms of resilience, durability and dimensional and shape accuracy. Therefore, they are manufactured using the most modern manufacturing methods from first-class steels.

Progressive tools

Progressive composite tools play a crucial role in the production of body structural parts for the automotive industry. These specialized tools enable the efficient production of complex and precise components that are critical to the safety and structure of a vehicle.


Progressive tools consist of a series of coordinated tools that are used one after the other. Each tool performs specific processing steps to shape the raw material into the desired shape. Typical processing steps include, among others:

- Punching: Punching creates holes in the material to create attachment points or openings for components.

- Forming: Forming occurs by pressing or pulling the material to create complex contours and structures.

- Cutting: Cutting is used to cut the material to the correct size or to shape edges.

Areas of application

Progressive composite tools are used in the automotive industry primarily for the production of body structural parts such as doors, fenders, roof and floor panels. These components must meet high strength and safety requirements while ensuring a precise fit. Progressive composite tools make it possible to meet these requirements efficiently and cost-effectively by ensuring automated and precise production.


Using progressive tooling offers a variety of benefits including:

- Precision: The sequential processing of the material allows very precise components to be produced with minimal tolerances.

- Efficiency: The use of progressive composite tools enables high productivity and rapid production of body structure parts.

- Flexibility: The tools can be adapted for different components and production batches, ensuring high flexibility in production.

Overall, progressive composite tools are indispensable tools in the production of body structure parts that contribute to the production of safe and high-quality vehicles. Their innovative and efficient functionality makes them an essential part of modern automobile production.

Transfer tools

Transfer tools are an important part of the manufacturing process for components in the automotive industry. These specialized tools enable the efficient production of precise and complex parts used in vehicles for various purposes. In this article we will take a look at how transfer tools work, areas of application and advantages.


Transfer tools consist of a series of individual tool stations that are firmly connected to each other. The workpiece is transferred from station to station, with each station carrying out specific processing steps. Typical processing steps in a transfer tool include:

- Punching: Punching creates holes in the material to create attachment points or other functions.

- Forming: Forming the material is done by pushing or pulling to create complex contours and structures.

- Cutting: Cutting is used to separate the material or shape edges.

Areas of application

Transfer tools are used in the automotive industry for a variety of components, including body parts, engine components, chassis components and interior trim elements. These tools enable the cost-effective mass production of parts with high quality and precision. They are used in the production of both cars and commercial vehicles.


Using transfer tools offers a number of benefits including:

- High productivity: The automated operation of transfer tools enables fast and efficient production of large quantities.

- Precision: Through the precise coordination of the tool stations, components with tight tolerances can be produced.

- Flexibility: The adaptability of transfer tools allows different components to be manufactured in the same production facility

Single tools

Individual tools play a crucial role in the production of components for the automotive industry. These specialized tools are used to create precise and complex parts that are essential to the construction and functionality of vehicles. In this article we will provide an overview of the functionality, areas of application and advantages of individual tools in automotive production.


Individual tools are specially developed tools that are designed for a specific processing step or a specific function in the production of a component. In contrast to transfer or progressive tools, individual tools are used individually and can be adjusted as required. Typical processing steps that are carried out with individual tools include:

- Milling: This process is used to remove material and create complex shapes.

- Drilling: Drilling creates holes in the material to create attachment points or other functions.

- Turning: Turning involves rotating the workpiece while a cutting tool shapes and processes it.

Areas of application

Individual tools have a wide range of applications in the automotive industry, including the production of engine parts, transmission components, chassis parts, and many more. They are used in both series production and prototype production to produce tailor-made components with high precision. Individual tools are also indispensable for vehicle repair and maintenance work.


Using standalone tools offers a number of benefits including:

- Flexibility: Individual tools can be adapted and used as required, which enables a high level of flexibility in production.

- Precision: Through the individual design and use of individual tools, components can be manufactured with high precision and tight tolerances.

- Versatility: Single tools can be used for a variety of machining steps and materials, highlighting their versatility in production.

Prototype tools

From the idea to series production

Prototype tools play a crucial role in product development and component manufacturing in the automotive industry. These specialized tools enable engineers and designers to transform concepts and ideas into tangible prototypes that are tested, validated and ultimately moved into series production. In this article, we take a look at the functionality, importance and benefits of prototyping tools in the automotive industry.


Prototyping tools are used to produce early versions of parts or components, called prototypes. These prototypes are used to check the design and function before going into series production. Typical manufacturing processes for prototype tools include rapid prototyping techniques such as 3D printing, CNC milling or casting. These processes enable rapid and cost-effective production of prototypes in various materials.


Prototype tools play a crucial role in the development phase of a new vehicle or component. They allow engineers and designers to test design concepts, identify errors and make optimizations before producing expensive series tools. Prototype tools allow iterations and improvements to be implemented quickly, increasing the speed of innovation in the automotive industry.


There are a variety of benefits to using prototyping tools, including:

- Speed: Prototype tools enable rapid and efficient production of prototypes, significantly reducing development time.

- Cost savings: By using prototype tools, design errors can be identified and corrected at an early stage, which avoids expensive changes in series production.

- Flexibility: Prototype tools make it possible to test different design variants and concepts in order to find the best solution for a specific component.
