A typical quick clamping system consists of 4 or more single acting hydraulic clamps which are mounted to both platens. Pressure must be maintained on the clamps and this is in most application achieved by using the EAS change system Air Hydraulic pump unit.
EAS offers the following double acting hydraulic clamps:
Working pressure of 350bar
Working Temperature: 0 °C to 200 °C (Viton O-ring installed)
Installation: slides in T-slot (most common) , Fixed on machine plate is also possible
Mould back plate dimensions are not standardized.
For retrofit applications these clamps can be ideally operated by the EAS change systems Air Hydraulic pump units.
The machine will stop if the hydraulic pressure drops below the defined safety pressure. In case of power faillure the cylinders will stay under pressure and the clamping function remains in operation.
ERC clamps have a T-slot pin. This pin can be adjusted to the actual T-slot dimensions.
