Single action press
Double action press
A double action press as its name implies has two slides operating along the same axis yet independent in their movements. In double action presses the second slide being an additional mechanism is spaced around the first original slide.
Triple action press
Triple action presses have three slides independent in their movement yet assembled within the same press frame. These presses are quite useful for complex drawing operations, where for example drawing has to be performed in more than one direction. In such a case the first drawing punch and the blank holder may draw the part to the appropriate size and dowel to allow for the third slides movement which pulls the material in another direction.
Multislide Press
May contain several slides assembled within a single press frame, with their range of operation along various axes. These slides may perform all kinds of work, either progressive or not.
Hydraulic Press
These are slower than mechanical presses but their tonnage force is maintained constant throughout the stroke no matter.
