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
