SOME OF THE BENEFITS INCLUDE:

Extreme freedom

At Invest Cast, Inc. we know product design is ever-changing and always improving. That’s why we allow you extreme freedom in part design. Your vision and our flexibility ensure that your ideas become reality – with speed and precision.

Excellent Surface Finish

Production – 100 RMS or Better
Prototype – 175 RMS is typical

Wide Selection of Alloys

Over 90 alloys are currently poured in alloy steel, tool steel, stainless steel, cobalt base, nickel base, copper base and aluminum base.

Economical Low and High Volume Process

Low volume production can be accomplished with relatively simple, single cavity tools while high volume production requirements can be met with fully automated multiple cavity molds.

Close Tolerances

Standard tolerances are ±.005″ per inch, 1/2 of Standard is possible.

Thinwalls

Wall thickness can be cast as thin as .025″, depending on alloy and part configuration.

CAD to Casting in a little as a few days

Prototypes generated from CAD File to Casting generally within days of receiving your order.

HOW IT WORKS

Production Casting Process

Wax Injection

The first step in the investment casting process is to produce a wax replica of the desired part. This is accomplished by injecting wax or plastic into a die cavity.

Pattern Removal

After injection, the wax replica is removed from the injection tool. Parts are inspected for tolerance and then cleaned for assembly.

Wax Assembly

Patterns are “wax welded” to a central sprue or cluster to facilitate pouring. Many patterns are attached to sprues for increased efficiency

Shell Building

The assembled sprue is then dipped or “invested” in into a ceramic slurry. After draining, the sprue is then coated or “stuccoed” with a fine ceramic sand. This process is repeated several times using progressively coarser grades of ceramic material to “build” sufficient “shell” strength.

De-waxing

The shell built sprue is then de-waxed by rapidly heating in a furnace or autoclave leaving behind the perfect shell cavity.

Preheating shell

The shells are then fired at 1600° to 2000°. This cures the shells interior into smooth, hard and strong ceramic material.

Pouring

The hot sprues are then removed from the furnace and poured immediately. The poured shells are then set aside to cool.

Part Finishing

When cool the shell material is stripped away from the sprue. Parts are then cut from the sprue.
