15.07.2019 Stamping/ Progessive Die Technology

Endless or strip sections, bending technology for rack electroplating or laser strips

A lack of skilled workers and increasing numbers in the prototype phase have led us to design and build a machine for endless belt and/ or strip sections.

This enables us to produce reliable small batches for our customers.

Laser cut for flexible customer requirements in cutting geometry, stamping and bending technology as in series production.

In addition: Everything naturally measured on our KEYENCE IM 6125 including statistical evaluation.

Typically quantities of 5,000 to 500,000 parts/ set per year.

Inhouse developed CNC-Laser Welding Machine

Increasing quality requirements in laser welding technology have prompted us to develop our own CNC laser welding machine.

Follwing: laser welding process of press-fit aeres in customer-specific distances.
Your advantage: No conversion costs for high-precision punching tools are required.
