Mullite/silica Pouring cups

Metsch pour cups are produced from high grade mullite 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/silica compositions (MRI 212 and MRI 219) offer beneficial product features as follow.

MRI 219 Product Features

High thermal shock resistance
Consistent smooth surface finish
Good mechanical strength
Over 30 years in continual use
Suitable for “Equiax” casting process only
Thermally compatible with shell systems using fused silica back-up coat materials

MRI 212 Product Features

Extreme thermal shock resistance
Good mechanical strength
Consistent smooth surface finish
Suitable for “Equiax” casting process only
Not suitable for use as a “primary” cup attached to the mold
Designed for use in “secondary” pour cup applications and for re-usable accessory products such as cup covers and discs

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
