Metal investment castings are typically produced from wax patterns. The production molds used to manufacture metal investment castings are commonly made from ceramic slurry coatings. The ceramic mold is fired in a furnace to drive out moisture & liquefied wax is burns off.Investment castings are a best solution for both small and large requirements, mainly used for the components with having design complexity & require fine detailing with perfection.The metal casting manufacturing process is also known as lost wax casting. Eventually it is used for prototyping of metal parts. The investment casting process begins with an investment casting pattern typically made of custom-formulated foundry wax. Wax as a pattern media is a used universally throughout the investment casting. A high quality wax will leave no ash after burn out to contaminate the metal casting. When fired the wax pattern will liquefy and completely melt out of the mold leaving a hollowed out form representing the final part geometry. Molten metal is poured (cast) into the mold, and it will be formed as a final part. Then after the part is ready for finishing operations. For more, Visit www.tooltecheng.com
