Ceramic tube for foundry

This form of ceramic is used in the precision foundry industry. The tubes and rods are incorporated into moulds  in the lost wax process. Using this technique, very fine tolerances on diameter can be obtained. The ceramic is leached away by the using sodium hydroxide solution once the metal has solidified. This leachable ceramic has a high porosity, does not have an organic binder, but does absorb water Ceramic tubes are non-eroding, and assure a smooth slag-free passage of metal to mold cavity without contamination or reaction with metal. Ends are precision-made for a sure fit. Ceramic Tubes are available in a wide range of sizes: standard plain end, mitered and male-female ends. We also offer bent,  oval, curved, notched and reducer tubes. Samples are available on request.We can supply the products according to customer's drawings, samples and performance requirement.
