TOOL MAKING AND DESIGN

Pilot-run and small-scale series tools in rapid tooling. Electrical discharge machining (EDM).

Precision and perfect timing – Wehl customers have been benefiting from these signature characteristics for many years. We master challenging requirements of the production of pilot-run and small-scale series tools using the latest software at 8 CAD/CAM design workstations. Interfaces for many commonly used data formats are available.

This also enables computer-aided, really fast mould separation and electrode design. The electrodes are manufactured on our HSC graphite machine and are fully automatically burnt into the mould inserts.

Specific tasks such as undercuts are realized using loose parts. Our many years of experience and expertise are also used to produce multi-component parts and parts with insert-moulded inlays and strip conductors.
