NeuSprue® wax sprues and base assemblies streamline the metal pour and deliver improved casting results. The two-piece base assembly screws together, eliminating floating trees and preventing trapped air between the sprue and base. it also provides easy removal after investing and protects the integrity of the wax tree and patterns. Use the base assembly and Neuprues with the NeuSprue® universal tree fixture to make your treeing easier.

A tapered, built-in button on all NeuSprue® wax sprues reduces the metal needed, allowing you to control the amount of metal in process. It also ensures a quick fill and reduces turbulence during filling. The specially shaped tip helps reduce turbulence and prevents the molten metal from splashing.
