A PLANT TOUR
We start with a
SARCOL's fully equipped model and
pattern shop allows us to start the process in a number of ways.
We can build models from a variety of sources including supplied
shrink model, prints, mylars, CAD data, or we can digitize an existing
part. SARCOL can also take existing part pieces for which prints
may have been lost and create a new mold while taking into account
shrinkage issues. Final details are CMM checked to insure complete
A pattern is made
from the model.
Once dimensional tolerances and all
of the details are determined, in the model, an exact pattern made
out of rubber, plaster or epoxy pattern is prepared. Complex parting
lines and unusual shapes can be easily built into the model and
later into the final cast metal mold. Ongoing cost savings are afforded
to our customers due the fact that the pattern may be used several
times with the same high tolerances as the very first.
The critical next
step is making the ceramic mold.
Next, in the cornerstone of the patented
SARCOL PROCESS, a special, high heat-resistant ceramic material
is poured over the pattern. The ceramic material blend incorporates
the most minute details of the original model, including ribs and
pockets. After being cured, the ceramic material becomes a hardened
Casting the metal
in the foundry.
A full range of metals and alloys
can be cast in ceramic molds using the SARCOL PROCESS including
a full range of tool steels, nickel, iron and beryllium-copper (same
as Mold Max billet that machine shops purchase). All of the complex
details captured in the hardened ceramic mold can be integrally
cast, eliminating what would ordinarily require additional machining.
Finishing the casting
SARCOL can perform a wide variety
of finishing operations based upon our customers particular needs.
Finishing options include: parting lines fitted, ground, EDMed and
matched; backs or all six sides ground; wall stock established;
and cavity and core surface finish in any grit required. Tolerances
are fully checked with our CMM and other quality control techniques.
