PHJ Range

  • Noise Controlled Anvil Jolt

  • High Pressure Hydraulic Squeeze

  • Louvered Sand Hopper with High Intensity Aerator

  • Accurate Centerline Draw Mechanism

  • Pattern Spray System

  • Optional Pattern Shuttle and Rapid Pattern Change System

  • PLC Based Control System

The PHJ range of machines are a 4-column, shuttle head style design that utilizes a low frequency, long stroke anvil jolt for pre-compaction of the mold.  Final compaction is by high pressure hydraulic squeeze.  This machine is available with a pattern shuttle for the alternate production of cope and drag molds and a rapid pattern change system.  This fully automatic machine is supplied with a PLC based electrical control system.  The squeeze and draw  functions are hydraulically powered and the remaining functions are pneumatically powered.

Intended for integration into fully automatic molding lines, the data shown below is representative of previously constructed machines.  Each machine model can be customized to meet specific application requirements.
