Standardize Dies

A standard rod-type clamp, when manually slid into the T-slot of the bolster (upper right) and placed in the clamping position, helps to achieve quick die changes.
When evaluating the pressroom for quick die change, ask if the dies are standardized for clamping and fitting, says Ellard. He suggests a standardized clamping height for the dies. “Better yet, mount all dies on subplates standardized for clamping height and left-to-right and front-to-back dimensions,” he says. Standardization will allow use of the same-size clamping fixture for all dies, and with standardized subplates, fixed die-locating pins can be used in the press bed for quick, accurate location of the die on the press bed. This makes for easier, possibly automatic, placing of clamps.


Having addressed staging and layout, storage, retrieval and transport, and standardization of dies, select quick die-change hardware. This includes control boxes, hydraulic power units, die lifters, bolster extensions, transport (forklifts, mobile die carts and rail-mounted die carts), die tables and rolling bolsters, and die-storage racks and hydraulic clamps, with ledge and rod clamps being the most common.

“Work with your equipment vendor to determine the QDC hardware necessary for meeting your plant’s needs,” says Ellard. “Remember, it’s important to visualize how any hardware purchased now might affect the future use of your pressroom equipment. For instance, if you have plans to add peripheral equipment such as transfer systems, feedlines and conveyors, these items must be considered when deciding on QDC hardware, and how and where to install it.” MF
