Wax Buttons plug into sprue base formers to facilitate accurate and correct direct sprue architechure for the casting of single unit patterns. The Sprue Button acts as a "funnel" to guide the molten alloy from the crucible into the pattern void resulting in dense castings. After casting, the smooth finish provides a clean cast button for re-melting. While most compeitive spruing buttons on the market are oversized resulting in alloy waste, Super Spru Buttons are shaped optimally to save alloy and reduce cost.
