Die drawing process: Fewer correction iterations and reduced manufacturing time
Traditional methods were no longer able to handle the constant price pressure and shorter and shorter lead times in the German die manufacturing industry. This was abundantly clear to Ralf Schmidt, Head of Die Manufacturing Engineering at Allgaier Automotive. He felt that a new approach was the only way to achieve a long-term competitive advantage.
Allgaier's innovative approach involved generating the method plan and die surfaces using dedicated software systems, with simultaneous mapping and optimization of the draw process and springback compensation with modified die surfaces within the software. The desired result was reduced costs for tool integration and required part modifications, which would result in further scheduling and cost benefits. Allgaier was aiming for a double-digit improvement.
Allgaier’s available resources and tools made it unrealistic to try to manage a project of this magnitude on their own. This led to a search for suitable partners with expertise that would complement the Allgaier die makers’ knowledge of die drawing and enable simulation of the entire process chain.
The company uses Tebis to create high-quality die surfaces that incorporate springback compensation and stability calculation results.
