Mullite Pouring Cups

Metsch pour cups are produced from high grade mullite-hybrid compositions tested and qualified by aerospace sector foundries for over 50 years. Designed for in-service durability. All features contribute to improving casting yields by assisting the foundry to protect the mold during handling throughout the process and by avoiding inclusions during the pour. Metsch offers both a standard line of pouring cup products, the Thousand Series, as well as custom design manufacture for unique customer requierements. The Metsch mullite composition (MRI 144) offers beneficial product features as follow.

MRI 144 Product Features

High thermal shock resistance
Ultra smooth surface finish and rounded firm edges
U-shape undercut shell lock grooves
High mechanical strength
Structural and surface stability during the pour
Suitable for “Equiax” casting process only

Types and sizes

Consideration of the optimal cup shape solution will first be given to the Thousand Series line of pouring cups which is available without a tooling charge. If a Thousand Series model does not meet your requirement, we will assist with the design/build of the custom pour cup shape for your mold and pouring requirements.

Type S – standard

Type F – with filter recess

Type E – elevated
