Investment
Casting ( Lost Wax Casting)
Investment casting, also called lost-wax casting, is one of the
oldest known metal forming techniques. Investment castings
allow the production of components with accuracy, repeatability,
versatility and integrity.
While investment castings are
generally more expensive than forged parts or those produced by
other casting methods, they make up for the higher cost through
the reduction of machining achieved through the near net-shape
and tight tolerances that can be held as cast. Many parts that
require milling, turning, drilling and grinding to finish can be
investment cast with only .020-.030 finish stock.
The
investment casting process maintains
typical dimensional accuracy of +/-.005"
per inch, with a surface finish of 125
RMS or better.
Engineering
We offer a wide
range of engineering capabilities that enable us
to produce the most complex parts, complete to
print. In addition, our ability to design and
produce all of our own tooling, fixtures, and
assembly equipment in-house, allows us
flexibility in delivering quality products, on
time
Quality
At SMI every project, part and
process is managed through our end-to-end quality assurance
process to ensure that the best quality product is produced. Our
proven quality system improves reliability and increases
production output with fewer defects and outstanding client
satisfaction.
Our primary facility has been very
successful in utilizing the Precision Investment casting process
to develop and manufacture net shape components in
a wide range of
alloys in
conformance with ISO 9001:2008 & AS 9100 :2003
certifications.
