General Info

Investment casting has, without a doubt, earned its place in manufacturing. The lost-wax process has proven to be a cost effective way to produce metal components. Parts can be reduced in weight, tolerances of +/- .005" per inch held, and expenses and time involving machining and finishing reduced or eliminated. The bottom line is, many parts are perfect candidates for investment casting. Our commitment is to produce the highest quality castings. At Texcast quality is not a new "buzz" word. We have maintained the highest quality to achieve consistent results. It has always been reflected in our final product.The lost-wax process provides unique opportunities for engineers and designers. Intricate structures can be created with minimum or no secondary machining operations.A pattern is produced by injecting wax into a permanent die. These wax patterns are mounted on tree assemblies. A shell is created by dipping the tree assembly into a ceramic slurry (this is called "investing" the shell), then a stucco coating is applied. A well designed tree assembly controls flow of metal. Proper controls in the casting process produce accurate and consistent results. Shells are dried and then heated to remove the wax (that's where the terminology "lost-wax castings" comes from). Shells are then fired to correct temperature. Metal is brought up to temperature and poured into the shell. After cooling, individual parts can be separated and carefully finished.
