Casting Design: Aluminum Permanent Mold Casting for Custom Motorcycles
Summary: Palmer Associates helps NH man design a custom
motorcycle derby cover exactly the way he imagined it..
Excerpt: When Larry, a motorcycle enthusiast from New Hampshire,
wanted to offer customers a unique and creative way to express their
appreciation for the American Armed Forces, he knew he had a great idea for a
motorcycle part. He saw that derby covers were available with many designs in
enamel and etching, but he couldn't find a powder coated, dual- layered version
to provide a higher quality product than what was available on the market.
Palmer Associates, experts in casting engineering services,
helped Larry design a Derby Cover exactly the way he imagined it, with a
weighted, free spinning outer cover. The cover features a sunken center, in
which Larry will insert decorative American Armed Forces insignia. Palmer
Associates connected Larry with a permanent mold foundry to create the desired
aluminum casting.

Cost Savings and Short Lead Times for Graphite Permanent Mold Aluminum Castings
Summary: Palmer Associates provides premier custom light fixture
manufacturer, Charles Loomis, with over 60% cost savings in seven weeks.
Excerpt: Do you require castings for your product with a short
lead time? Then a graphite permanent mold casting solution may be the casting
process of choice. Why settle for a fragile SLA model when you can get
production ready graphite molds cut within a 4 week time frame. The actual
aluminum or zinc aluminum alloy castings will be exact to your end product. The
Charles Loomis Company needed metal components for a new lighting fixture that
was to become a part of displays in Nordstrom department stores, they approved
the Graphite Permanent mold casting process and ultimately, approached
Castechnologties, Inc. to get engineering design assistance and machined
castings.

Designing with Investment Casting
Summary: Casting by the investment process allows for parts to
meet x-ray and non destructive testing specifications for: military, aerospace,
semi conductor industry, valves, pumps and many other industrial applications.
Excerpt: When your design calls for a complicated, thin wall
casting with undercuts, holes, bosses and hardness or strength requirements,
investment castings may be the casting process for your parts. Simple designs
are also cast using the investment casting process as well. The process begins
with production of a heat disposable pattern, usually made of wax or plastic.
The pattern is dipped into a refractory slurry and then, into fine sand. Once
the slurry sets, the process may be repeated. the pattern is then melted out in
a steam autoclave, leaving the ceramic mold cavity behind. After being hardened
in a kiln at about 2000 degrees, the mold is ready for metal to be poured in.
Once the metal cools, the ceramic shell is removed.

Benefits of Graphite Permanent Mold Aluminum Casting Process
Summary: The graphite permanent mold process employs gravity
pouring of metals using graphite molds. The castings produced have excellent
grain structure and extremely low porosity which result in superior ductility
and outstanding strength.
Excerpt: The graphite permanent mold casting process combines
the low cost of machinable graphite molds with a high strength aluminum (356 T6)
or zinc-aluminum alloy (ZA-12) to provide an economical alternative to other
casting processes in annual volumes of 500-15,000 pieces per year. The graphite
molding process is rather simple. Two mold halves with cavities cut out in each
half are pressed together and molten metal is injected into the mold under low
pressure. The mold is then held together throughout the solidification stages of
the casting. The mold halves are separated, the casting removed and the process
is repeated.
