Permanent Molding
T&L Foundry’s Permanent Mold department produces castings by Conventional, Tilt Pour and Low Pressure methods. As in Sand molding, we concentrate on internal integrity and excellent surface finish parts. Typically cast iron or Meehanite (a dense cast iron) is used as the mold material and the cores are made from metal or sand. Cavity surfaces are coated with a thin layer of heat resistant material such as clay or sodium silicate. We also have the ability to cast-in inserts in our permanent mold processes.
