RAPID TOOLING - TOOL MAKING, DESIGN, FIXTURE CONSTRUCTION and INJECTION MOULDING

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

Precision and perfect timing – Wehl customers
have been benefi ting 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.
Specifi c 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 insertmoulded
inlays and strip conductors.
