Mullite Mold Support Rods
Extruded of high grade mullite or high purity alumina (for higher operating temperature capability), Metsch mold support rods are thermally compatible with most shell systems and all Metsch pouring cup materials to avoid cracking of the shell or pouring cup due to a thermal expansion mis-match.
With it’s Thousand Series line of standard mold support rod products, Metsch makes various profile shapes available without a tooling Charge: Round, Half-Round, Square and Rectangle. Each profile profile shape is available in multiple profile sizes.
All Metsch mold support rods are cut to length in the “green” state before firing to provide a clean end cut and to avoid micro-fractured ends due to “snapping” to length or post-firing cutting. Custom profile shapes and sizes can be quoted upon request.
