Stamping technology
When it comes to stamping technology, we’re passionate about exploring the absolute limits of what is possible. With our high-end stamping tools perfectly designed for production, we’ve laid the foundations to ultimately be able to supply perfect products in large quantities with state-of-the-art automatic stamping presses.
State-of-the-art machinery
featuring highly modern equipment and presses weighing 10–80 metric tons that form the core of our stamping technology
Single-stage production of highly complex parts
by means of progressive tools that integrate the supply of components and manufacturing from multiple conveyors into a single stamping process
Stamped parts along the limits of feasibility
always produced to perfection, even when dealing with a multitude of complex materials, surfaces, sheet thicknesses, and geometries
Maximum productivity & cost efficiency
thanks to highly precise stamping tools and state-of-the-art workstations for high stroke rates and a stable process chain
Series production of stamped parts
Our high-precision stamping tools form the basis for the economical production of millions of parts that retain their high quality throughout their lifetime. Comprehensive and continuous quality monitoring is carried out throughout the stamping process. We also provide this for bulk goods manufacturing.
Single-stage production
Our progressive tools allow for different levels of vertical integration within the stamping process. As a specialist in single-stage and multi-stage manufacturing concepts, we offer our customers a wide range of combination technologies. The infeed of multiple conveyors, simultaneous stamping, and combination in a tool is one of our key areas of expertise, along with the precise introduction and assembly of additional components (plastic components, filters, springs, etc.) on a line.
An overview of our stamping technologies
We integrate various procedures into the stamping process. These include the assembly of two or more parts, bending, deep drawing, solderless connections, contact rivets, resistance and laser welding, laser marking of parts, and thread forming, to name a few. A wide variety of feeding and wrapping methods, e.g., horizontal, vertical, or feeder bowls, allow for a high level of flexibility in processing a wide variety of material thicknesses and dimensions.
Deep drawing
In our micro-precise manufactured tools, stamps, matrices, and hold-down devices are perfectly coordinated to one another. This allows us to achieve perfect processing results for complex deep-drawn parts with maximum efficiency. For this, we use a variety of materials with sheet thicknesses starting from 0.07 mm.
Examples of applications in which deep drawing is integrated into the production line:
- Caps for infusion bottles that are used in the medical industry
- Stainless steel diaphragms for various applications
Process welding
We integrate various welding procedures for the complete manufacturing of complex stamped parts within our production lines. Welding with laser beams within the stamping stroke also allows for a permanent positive fit even at high stroke rates, and is therefore a preferable method for filigree contacts. Resistance welding is particularly suitable for combining and affixing various contact materials.
The welding technologies that we directly integrate into the stamping process include:
- Resistance welding of round or profile wire for switching contacts in industrial applications
- Laser welding at connectors, mainly for applications in the automotive industry and solar technology
PRESS-FIT TECHNOLOGY
This solderless connection technology is mainly used in the contacting on printed circuit boards. Pressing the connectors into the PCB creates a gas-tight and mechanically reliable electrical connection between the PCB and the connector.
Our portfolio in the field of press-fit technology consists of the KRAMSKI Compliant Pin as a tried-and-tested in-house development, as well as the licensed manufacturing of the EloPin®.

Contact rivets
As a perfect basis for meeting the high requirements of switching systems, contact rivets are not just used in the processing of conventional materials, but of special ones as well. Regardless of whether rivets are formed from a wire or by feeding an external rivet via a feeder bowl and applying this with high precision – we develop suitable solutions for the smallest tolerances that push the limits of feasibility. In addition to standard shapes and processes, we offer custom tool solutions and process steps to be able to satisfy special applications as well. Wire rivets and bimetal rivets are used in safety relays, the automotive industry, and in industrial plants.
Finishing processes
In our follow-up processes, we perform finishing procedures for our products in a targeted fashion along the value chain, thereby honoring our commitment to quality down to the smallest detail.
