Product Description

Static Pressure Horizontal Automatic Molding Line

Product Detail:

The design of multiram squeeze head allows easy maintenance and free access.
The hydraulic cylinders of the multiram press are individually controlled and use connected hydraulic oil flow to reach equal compaction of the mould.
Compaction of cope and drag mould may be varied to reach a higher gas permeability of cope mould as well as to work with exothermic feeders.
