Weir’s global critical solutions is
a system of custom manufacturing replacement, or, obsolete parts
without the need for expensive tooling. Combining proven
technologies with computer aided manufacturing, cast and machined
parts can be delivered in an extremely short period of time to suit
our customers.
Frequently a problem exists due to lack of
specifications. Our mobile, co-ordinate measuring techniques
allows us to quickly replicate parts by measuring a spare right in
your shop. Even complex internal geometries are easily and quickly
modeled into a wire-frame drawing.
Material specifications are determined using a
hand-held x-ray interferometer and input into the CAD software.
The result is a 3D electronic representation
of your part accurate to 0.001 inches.
Once in electronic format, use of rapid
prototyping technology creates a physical model of the part in a
cellulous material. This model is dipped in a ceramic slurry and
allowed to cure.
A sintering process melts out the cellulous
leaving a hollow mold that is then filled with molten metal. Once
cool, the result is a raw casting.
While the foundry process is ongoing, CNC
programmers create the control program for our multi-axis CNC
machines.
Once received by the machine shop,
the componenet of the part is machined and finished to
the developed specification.
The benefits:
·
The process is fast with typical delivery being six to eight
weeks.
· No pattern or
other “tooling” charges
· Investment
casting is inherently of excellent quality and surface finish
· Any ferrous or
copper based alloy can be employed
· Design
modifications are easily accommodated
· Your spares never
need to leave your site
· Highly
economic
· To update
obsolete materials or antiquated manufacturing processes with more
current less-expensive technology
·
Remanufacture virtually any spare part.
