Hydraulic Core & Ejection Systems

• A hydraulic bumper plate, actuated by double hydraulic cylinders, is standard on 850 ton and larger machines. Two advantages of this system are a large area for 'knockout' rods and the versatility to accommodate many different sized dies.
• Center hydraulic ejection is standard on 500 to 650 ton machines
• A mechanical knockoutsystem is standard on all other machines, but can be upgraded for one of the above systems as an option.

Die core directional valves are manifold mounted and include flow and pressure controls. One direction, flow and pressure valve is standard on 500 ton and larger machines. Various control sequences are available and reviewed with each customer.
