So, what are the
advantages of spin-casting over other casting technologies?
Conquest's process can provide high integrity, close tolerance,
zinc Pewters, white metals & plastic castings with exacting
details. Surface finishes & tolerances comparable to standard
die-casting and injection molding techniques, but at a fraction
of start-up and production costs, with no hard tooling requirement.
CONSIDER THESE ADVANTAGES...
RUBBER MOLD TECHNIQUE. Up to 95% savings
on tooling costs are possible by using our newly developed
High Temperature and High Strength silicone rubber compounds,
designed specifically for repeated spin-castings of zinc
and plastic.
PROTOTYPE CAPABILITIES. This process
is capable of producing zinc and plastic designs that require
strength (such as for hardware applications) and is also
an economical method utilized to manufacture prototypes
for customer or for market acceptance.
IMPROVED CASTING DETAIL & UNDER-CUT CAPABILITIES.
QUANTITIES RANGING FROM 1 PIECE TO A HALF MILLION
PIECES. Short to medium production runs are now
economically practical since the manufacturer can eliminate
high tooling costs or the expense of having parts either
fabricated, machined or made as hand finished sand castings.
FAST DELIVERIES. Our silicone rubber
molds also provide the user with same day samples and fast
production quantities.
COSTS AND PARTS SIZES. Parts size range
from a fraction of an inch to 15" long x 11" wide
x 5" thick. In some applications, tolerances as close
as +.005 can be held. On normal runs, the price per piece
is comparable to regular die-casting and injection- molded
costs.
COMPUTERIZED DESIGN AVAILABILITY. In
addition, Conquest Industries offers a computerized, state-of-the-art,
model-making system. Capable of scanning standard 2-D artwork
and three dimension parts, it creates 3-D designs on your
computer screen. A desk-size milling machine completes the
system. It machines the master part to be used in the spin-casting
process. This is a cost effective alternative to the traditional
hand engraving and modeling procedures.
Are there size
limitations when using the spin - casting technique?
Parts you can make with the spin-casting technique range from
a fraction of an inch to 15" long X 11" wide X 5"
thick. In some applications, tolerances as close as ±
0.005" can be held. Depending on the alloy to be cast,
the part thickness can be as thin as 0.5 mm for tin alloys,
and 1 mm for zinc alloys.
Mold Making
What are the mold-making materials and how is selection determined?
There are two types of mold-making materials in the spin-casting
industry. One is made of organic rubber, and the other is made
of silicone rubber. Organic rubbers are sometimes called black
rubbers because they are normally reinforced with carbon blacks.
The following table lists the basic characteristic differences
of these two materials.
Property
Organic Rubber
Silicone Rubber
Tensile Strength
Tear Strength
Heat Resistance
Workability
Because of the above property differences, these two kinds
of materials are used for different applications, as shown
in the following table.
Organic Rubber
Silicone Rubber
Casting Metal
White metals (tin alloys) or other low melting points
(less than 600º F) alloys
Primarily for zinc alloys, but can also be used for
casting large white metal parts.
Undercut/Design Complexity
Handles undercut well.
Prefer flat, less undercut parts
Conquest provides a series of organic and silicone
rubber mold making materials.
