Cone Sprue Bases - Tree Style - 4" x 3/8" Diameter

This tree-style sprue base measures 4.0 inches in height with a 0.375-inch (3/8) center diameter. It serves as the foundation for organizing multiple wax patterns into a single casting tree. The cone shape helps guide the flow of molten metal into the main sprue with minimal turbulence.

It is compatible with standard rubber bases used in vacuum and centrifugal casting processes. This component is essential for maximizing the number of pieces cast in a single flask for efficient production.
