CFS Investment Casting services
In-House Tooling Services
Investment casting tooling, also called wax pattern tooling, is necessary for all investment castings. The tool is made from high grade aluminum alloys, and designed to allow the flow of molten wax under extreme pressure, in order to allow it to solidify into the wax pattern which is used to form the ceramic mold during the investing process. Unlike sand casting, investment casting tooling replicates the final casting in reverse, due to the fact that we cut “cavities” in which the wax flows to form our patterns. This tooling is often designed to be “collapsible”, in other words, it must be able to be taken apart to remove the solid wax patterns when they have cooled. Another critical element of the tooling design is that the tooling must be constructed so that the wax patterns produced are larger than the final casting dimensions.
Machining Services
CNC Machining is one of the value-add services that CFS foundry can supply after investment casting. When you are tired of sending investment casting blanks out for secondary machining operation, CFS foundry is your one-stop-shop for precision machining. We have in-house cnc machining capabilities with excellent machining experience.
Heat Treatment Services
Heat treatment of precision investment castings is a metal processing technology to ontain expected properties by heating, warming and cooling. Heat treatment is one of the main technologies during investment casting process. After heat treatment, it will not change the shape and whole compositions of investment castings, but will endow or improve the working performance of products by change the inner microscopic structure, or change surface compositions of investment castings. Investment casting heat treatment expands the mechanical properties of metal alloys by providing higher thresholds of corrosion resistance, abrasion resistance, and hardness.
