Overview

PRECISION VAC EXPAND

PRECISION VAC EXPAND is an extension unit mounted close to the mold. The shorter the path, the shorter the actuation time — and the better the vacuum efficiency at the point where it actually matters.

It is the vacuum solution for high-tonnage casting, where cavity volume and fill speed leave no margin for a slow-responding system.

Up to four extension units can be connected to one PRECISION VAC EXPAND.

  • Extension unit mounted close to the mold
  • Faster response time
  • Improved vacuum efficiency
  • Connect up to 4 extension units to one system
  • Sizes available: 300 · 500 · 800 · 1000 L
