Variable Tooth Geometry


Facilitates release during ejection

Use when sticking is of concern

Radii on teeth to help facilitate ejection

Increased draft on side angles of teeth

Midland’s patented Variable Tooth Geometry features radii on the inlet side of the tooth pattern which collects more material to support ejection in each casting cycle. Increased draft on the side angles of the tooth pattern further assists with release.

Radii decrease progressively toward the outlet side of the block to help prevent spitting or blow-through. The Variable Tooth Pattern can be applied to any Valve-Less Vacuum or Vent Block.
