Quick solutions thanks to 3D printing
With our new Prusa CORE ONE L 3D printer, we can put bespoke solutions into practice even faster: components can be designed, printed and tested on the mould right here in-house.
A recent example: a component for a sensor mount was required at short notice – instead of waiting for an external manufacturer, we were able to produce it ourselves and put it into use straight away. If the component had been milled, it would have been significantly more time-consuming and costly.
Our applications:
• Fixtures and test parts for toolmaking and automation
• Mounts and adaptors for sensor systems
• Sorting and organisation solutions
• Demonstration and functional models
Technical specifications:
300 × 300 mm build volume, heated chamber and the ability to process a wide range of plastics.

Summer party boosts team spirit
With the holiday season just around the corner, the daily grind took a back seat for a moment: at this year’s summer party, numerous staff members came together to spend the afternoon in a relaxed atmosphere.
With barbecued specialties, a varied salad and dessert buffet, and an entertaining team game, the focus was on personal interaction and camaraderie.
A heartfelt thank you goes to all our colleagues who contributed to the success of the summer party by bringing along their own delicacies and offering their support.
Joint events such as this foster cohesion, strengthen team spirit and are an important part of our corporate culture.

From Die Casting to Lightweight Solutions
How can you replace a die-cast housing with plastic without sacrificing the necessary EMC shielding?
Together with Intensa, we have developed a solution for this. The result is currently being presented at the Battery Show Europe 2026 in Stuttgart at our partner Intensa’s booth (Booth 1-A40). The trade show takes place from June 9 to 11, 2026, at the Stuttgart Exhibition Center.
Our contribution:
– Stainless steel EMC shielding
– Material thicknesses of just 0.10 to 0.15 mm
– Smooth or domed geometries
– Production-ready precision for cost-effective high-volume manufacturing
The result is a lightweight and functional solution for modern battery systems and inverters.
We are pleased to be part of this forward-looking development with our stamping and forming technology.

New Straightening Technology – A Value-Adding Upgrade for Our Stamped Parts
We have strategically advanced our production capabilities by integrating state-of-the-art straightening technology into our existing RASTER 315 t / 3,150 kN press.
With the GSW straightening machine, we optimize the interface between the coil material and the stamped parts, aiming for even more stable processes and consistently reproducible quality—especially for demanding stamped components.
Key benefits include:
– Maximum strip width of 800 mm
– Increased safety & simplified operation
Hinged design for easy threading and fast cleaning
– More precise straightening results
Tighter flatness tolerances thanks to a straightening machine perfectly matched to our products
– Designed for modern material requirements
– Uniform drive force & higher straightening Performance
The improved straightening quality has a particularly positive impact on stamped parts such as our carrier frames for seals. These components are used, for example, in oil pan gaskets, battery cover gaskets, transmission cover gaskets, and cylinder head gaskets. Uniform material guidance before the stamping process supports tight tolerances, high repeatability, and stable downstream processing.

Our conclusion:
With this investment, we are specifically strengthening the quality of our stamped parts. Better-straightened coil material means greater precision, reduced scrap, and consistently reproducible results—for us and for our customers.

Your solution provider at Blechexpo 2025 in Stuttgart
At the 17th Blechexpo in Stuttgart, we will be demonstrating our manufacturing capabilities and our great flexibility.
We will be presenting our expertise in stamping and forming technology in the following areas:
· Stainless steel shells for thermal and acoustic insulation solutions
· Steel and aluminum support frames for seals
· Stamped parts for batteries, e.g., cell connectors and busbars for current-carrying components
· Stamped and sawed parts for photovoltaic applications
In addition, we have two great trade fair offers for you:
· Free initial simulation of formed parts
· Free testing + ROI calculation for carrier frame seals
We look forward to talking to you: Our team is available to answer all your questions, discuss ideas, and talk about project ideas. Bring your stamping challenge with you to the trade fair and we’ll talk about it – over coffee, refreshments, and snacks.
