Precision investment casting allows us to
choose the appropriate design and material based on product
requirements instead of the limitations of a particular manufacturing
process. Discover for yourself why this is an ideal casting
method.
INTRICATE PARTS MADE EASY
Manufacturers are constantly confronted
with the need for intricate parts. Due to their unusual shapes
and contours, finished internal surfaces, etc., these parts
used to require expensive machining and many hours of labor
to produce. By tailoring our castings to fit the exact specifications
of a particular part, Rimer Enterprises can simplify this
problem, thereby eliminating fabrication and greatly reducing
costs.
ELIMINATION OF FINISH OPERATIONS
The smooth wax pattern and fine grained
investment material used to produce investment castings ensures
an even surface on every cast piece. Regardless of the alloy
used, you can expect a micro-finish of 125. Most investment
castings are used with “as cast” surfaces. When
aesthetics or function requires a smooth surface, investment
casting is unparalleled.
ELIMINATION OF MACHINING
In many specifications, the materials used
are extremely hard and tough. To machine these parts requires
expensive tools, hours of labor, and high costs. Investment
casting eliminates the need for machining to size and therefore,
the expensive material loss associated with it.
LOW COST TOOLING
Dies or molds employed during the investment
casting process are much less expensive than those used in
die casting, stamping, or forging. In investment casting,
molds are used to produce wax patterns; therefore they will
last forever. With other methods, dies are expendable and
their frequent replacement proves to be very costly. Investment
casting molds are not hardened so changes can be made quickly
and inexpensively.
MULTIPLE PARTS ASSEMBLIES
While the assembly of a number of separate
parts may seem to be the obvious method to perform a certain
function, it is often the most expensive. To do the same job,
a careful analysis of the blueprint may show that it is possible
to combine different parts of the assembly into a single investment
casting. This leads to great savings in machining and labor
costs. Investment casting can produce what would be impossible
by any other method.
