PBH system

Objective/Potential applications
The result of the work is novel system providing minimised average blank holder force, optimised frequency and amplitude. Application in automotive, aircraft and consumers articles industry.

Manufacturer of metal sheet parts of above mentioned industries.

Main Innovations
The system shows clear advantageous compared with a conventional process when drawing stainless steel and high strength steel on the drawing of an oil pan. In the special case this resulted in: material reduction: the material thickness in oil pan production could reduced by 30%; productivity: the drawing deep could be increased by 25%, so deep drawing steps could be saved; product quality: the part strength was increased by increasing the strength of the weakest edge by 4,5%.

Analysis of market
Estimated market for NEFF from 2006:
Installation size 2000kN, ca. 370t€/press (each 2 per year)
Installation size 4000kN, ca. 500t€/press (each 2 per year)
Installation size 6000kN, ca. 800t€/press (each 2 per year)

Potential barriers
When reaching the project targets no barriers should limit the exploitation.
