Alumina Vent Plugs
Metsch vent plugs are hard ceramic products used to plug wax vent holes molded on complex wax pattern assemblies to assist with the de-wax of the mold. Metsch vent plugs are designed with tapered sides to prevent pushing the plug through the vent hole into the de-waxed mold. All Metsch vent plugs have radius on edges to avoid emitting ceramic inclusions into the pour. The Metsch vent plug product line includes 3 sizes: small, medium and large. Thousand Series line of vent plugs is available without a tooling charge. Custom vent plug shapes can be designed and molded to form fit to your wax vent shape.
