Our PERC system gives you unscrewing options. If your application calls for 40 revolutions of a 1/32 pitch thread, and you don't have the space to accomodate almost 21 feet worth of rack and cylinder, PERC is your only option.

If your part requires clean room molding, a hydraulic mechanism of any sort cannot be used in that environment. The electric PERC system is again your only option.

Hydraulic Systems

The PERCtm System

  • Motion limited by the length of cylinder stroke
  • Time consuming set-ups and frequent maintenance
  • Molds with hudraulic systems will sometimes require larger molding presses
  • Messy hydraulic hoses and connections
  • Requires auxilary equipment with electric molding machines
  • Accurate, fast and efficient core positioning with unlimited turns and programmable speed profiles
  • PERC's compact size makes for fast and easy setups
  • Allows for use of smaller presses
  • Eliminates messy hydraulic oils
  • Perfect match for electric molding amchines
