Type PHJ
Based upon the HJ range, these Four Post configured machines offer improved mould density and hardness values, castings produced exhibit superior surface finish and dimensional tolerances, as most of the available squeeze forces are concentrated on the mould and not dissipated through the cantilever construction of conventional machines. The machines feature shuttle type squeeze head and can readily accept a pattern shuttle system for the alternate production of cope & drag moulds. Centre line draw system allows extremely complex castings to be easily stripped. The machine can easily regulate the squeeze forces employed and thus allow existing pattern equipment to be used with very little modification.
Special Features:
- Noise Controlled Anvil Jolt
- High Pressure Hydraulic Squeeze
- Louvered Sand Hopper with High Intensity Aerator
- Accurate Centreline Draw Mechanism
- Pattern Spray System
- Optional Pattern Shuttle and Rapid Pattern Change System
- PLC Based Control System
- Automatic Lubrication
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.
