Pre-formed wax quick sprue gates join wax patterns to the distribution bar. Every pattern will always be the same distance from the metal supply ensuring consistently dense and complete castings.
Quik Sprue Square Gate Channels
As molten metal passes through the Quik Sprue gate, it forms small spheres to enter the pattern void. Displaced gasses and air in the casting ring are allowed to escape through the corners of the unique square gate channel. This provides for complete elimination of gasses, controls shrinkage porosity and investment cracking.
Quik Sprues are available in three sizes for various pattern volumes. Use the smallest quick sprues on individual anterior copings and the larger sizes on full metal crowns and pontics (large patterns may require 2 sprues per unit and multiple unit bridges need a Quik sprue gate for each unit).
