Four-Column Hydraulic Press

(Double Action Drawing)

Four-Column Hydraulic Press

This particular four-column hydraulic press is a double action deep drawing press used to create more complex deep drawn stampings. The double-acting components of the hydraulic press help create deep drawn metal parts without wrinkles and greatly increase the speed of the metal forming line.
