There are many different kinds of casting, but one of the more common types of casting is stainless steel investment casting. As a Commerce City, Colorado foundry, we often work with stainless steel to cast prototypes and tools for our clients. But why do we use steel so often? Stainless Steel Stain…Read More
Rapid Investment Casting
OUR RAPID INVESTMENT CASTING PROCESS IS AN EXCELLENT AND COST EFFECTIVE ALTERNATIVE TO EXPENSIVE PARTS PRODUCED USING DMLS OR ADDITIVE PROCESSES.
Using a 3D wax pattern printing system, we can quickly create complex wax patterns for a fraction of the cost of DMLS. The print envelope is approximately 8 x 8 x 7 inches. The wax patterns are invested and burned out of the mold. Metal is then poured into the resultant cavity. Unlike parts made by additive processes, these parts are full-strength castings in the alloy you want to replicate for production castings..
This rapid investment casting process allows us to ship you a limited number of castings in as little as 2 days, depending on geometry and complexity. Our process is appropriate for Aluminum, Magnesium, Zinc, and Stainless Steel.
Casting tolerances vary depending on part geometry and metal being used, the minimum casting wall thickness for stainless steel is .125, aluminum is approximately .080 and the minimum wall thickness for magnesium is also.080 inches. Zinc flows differently and can achieve thinner wall thickness, but keep in mind it is heavier than aluminum and magnesium.
Advantages: Speed; Complex Geometry (internal features, undercuts, and thin walls are all possible)
