.... If the trial lots show that die design changes are needed, the changes can be made at less cost before the conventional die is completed. After the conventional die has been set up, either the entire production can be transferred to it or both dies can be used. For small quantities (<100 pieces), even...

... in this die, and the ejector pin advances to eject the finished piece. In a cold-heading machine with progressive dies, the transfer mechanism has fingers in front of each of several dies. After each stroke, the ejector pin pushes the workpiece out of the die. The transfer mechanism grips it and advances...

... (see the section “Bending Dies” in this article). Dies may also be designed for single-operation function, or multiple forming functions can be implemented more efficiently with the design of compound dies, progressive dies, and transfer dies (see the subsequent information).

.... In an automatic operation using progressive dies or transfer mechanisms, at least one-half the stroke must be reserved for stock feed, because the tooling must clear the part before feeding begins for the next stroke. For automatic operation, it is common practice to allow a press stroke of four times the length...

... is to be preferred. If entrapped in the coining dies, lubricants can cause flaws in the workpieces and premature die failure as well. For example, under conditions of constrained plastic flow, an entrapped lubricant will be loaded in hydrostatic compression and will interfere with the transfer of die detail...
