Costs, complexity demand more tool operations

Hülshorst, who for some 10 years had a tool-making firm for progressive composite dies, named a further trend to which installation constructors have to react: tool length.

“The cost pressure and component complexity are forcing firms to integrate more and more operations into the tool so that, as far as possible, components ‘fall finished’ from the installation, in many cases including test procedures.” Constantly becoming longer, these tools present new challenges for pressing technology.

“Since the rising non-centred forces arising during the punch stroke make strong demands on the anti-tipping stability of the press, here we see a great advantage for our spindle presses, whose anti-tipping stability in fact even increases with increasing table length due to the system,” Hülshorst explained. “Customers select the machine dimensions independently of the pressing force. This sets us clearly apart from the competition.”

For any firm processing endless products from coil in large batches, rotary punching is a genuine alternative to stroke punching. Baust Stanztechnologie will be coming to Hannover again for the 10th time now with their own stand to present information on the topic of rotary punching. On show will be a selection of rotary punching solutions for the most varied requirements.

Visitors can further expect an overview of configurations individually tailored to customers. “One of our highlights this year is a completely mechanical punching insert which is ideal for thin, narrow material – for plaster rails and corner angle sections,” according to Achim Bettenhausen, who runs operations and sales in Germany. With rotary punching, also known as roller punching, material thicknesses of up to 3.0mm can be processed.
