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.

2025:
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.

2019:
Hannover Messe 2019 – Hall 4 / E24
After a long break, we will once again exhibit at Hannover Messe this year – at the Baden-Württemberg International bw-i joint stand. From the single stamped part to the complex assembly we will show a lot from our product portfolio.
We will be there for you from 01.04.2019 to 05.04.2019 and are looking forward to your visit.
