Stamping Technologies

State-of-the-art stamping machines from leading manufacturers as well as tools with special safety systems guarantee high quality and delivery reliability. Our high-performance machinery encompasses over 70 stamping units. These are used to stamp, coin and bend strip and semi-finished products.

• Pressing forces: 18 - 250t
• Strokes per minute: 100 – 1,400 
• Material strengths: 0.06 – 4.00 mm
• Material widths: up to approx. 200 mm
• Materials: Copper and alloys thereof, steel, stainless steel, aluminum, special alloys 

Furthermore, all precision stamped parts can be provided with various electroplated surfaces (partially or completely) on in-house machines. 

The Tool & Stamping Center is equipped with a wealth of high-tech machines and profits from its longstanding experience in the manufacture of sophisticated tool concepts. Small quantities for pre-series production, prototypes and serial production involving large volumes can thus all be produced in an economic way.

Diehl Metal Applications produces customer-specific prototypes to provide advice with respect to serial production. The prototypes correspond to the later series parts and are produced in-house and at near-series quality. All relevant production steps and the technologies used are effectively aligned with each other in such a way that the individual customer requirements can be fulfilled.

The testing laboratory uses real time characteristic values to test and analyze the prototype, so that it can be optimized based on the results.

Our inhouse Tool Center allows us to carry out all process steps at our company – from CAD design to the finished tool. In this way, we can ensure the supply of required tools to our internal production processes at short notice and at the highest quality – either by producing new tools or making changes to existing ones. These tools include: 

• Sinking & wire erosion machines  
• CNC milling and drilling centers 
• High-speed milling centers 
• Grinding machines, surface & profile grinding machines
• Coordinate grinding machines
• 3D tool measuring equipment

In stamping technology, precision, production reliability and production speed can only be achieved with optimum interplay between Product Development and Tool Manufacture. Short development times and high investment activity help to ensure that our customers and partners receive functional models (prototypes) and small batches within a short space of time.

To ensure quality control, not only do the Machine Operators carry out self-checks but modern video monitoring systems are also employed to ensure 100% process inspection for surfaces, contours and dimensions. Strip cleaning units may be integrated prior to the video inspection. In this way, de-oiled and cleaned stamped strip can be produced inline in the stamping process at delivery quality.

Diehl Metal Applications develops and produces complete or partial solutions along the value-adding chain, based on customer requirements: 

• Support in selecting intelligent material combinations 
• Highly integrated production processes in copper alloy production
• State-of-the-art stamping & surface technologies
• Overmolding & assembly technology

Our customers and partners are free to decide at any time whether they want a partial solution where they provide the material, or if they wish to hand over the entire process to us.
