 Deep Drawn Stampings
Deep Drawn Technology
Transfer Press (Eyelet Machine) tooling is primarily used to produce deep drawn parts. Unlike a progressive die, the parts are transferred from station to station by "fingers" instead of a carrier strip. This saves a considerable amount of raw material and part cost as there is no need for the carrier strip. Each station has its own tooling so control of every component within each station is greatly enhanced. This makes it easier to maintain tight tolerances and make tool adjustments since the individual stations can be worked on rather than removing a whole progressive die from a press.
Often, other features such as side pierced holes, notches, coined or knife edges can be incorporated into the tooling using special "sub dies" mounted into individual stations. This saves the high cost of doing secondary operations.

 Multislide and Fourslide Stampings
Multi-Slide Technology
Multi-Slide tooling is often selected where extensive bending operations are required and less expensive tooling is desired to produce complex parts. The raw material is fed into the machine and may first go through a progressive die, where punching, coining, piercing, or other operations may be performed. Then the material strip comes out of the die and the part can be bent or formed by a series of cams and will be cut off from the strip immediately after the forming takes place. Unlike a conventional power press, the multi-slide and four-slide machines stamping motion is horizontal rather than vertical and the part can drop down off the post that it is formed around. Forming can be done at different levels as well.
Volkert Precision's Multi-Slide and Four-Slide Department specializes in close tolerance, small, thin metal parts and where possible utilize tooling designed to run without or with minimal scrap. With the high cost of metals, especially precious metals, this can result in considerable part cost savings.

 Progressive Die Metal Stampings
Progressive Stamping Technology
Progressive dies allow a stamper to produce a finished part (in most cases) off one tool by incorporating many operations within the same tool. These operations can include notching, punching, coining, forming, tapping, bending and even assembly in some cases.
An automatic feeding system pushes or pulls a strip of material from a coil through all the stations of a progressive die. The part is carried from station to station attached to a carrier strip. At each station the part is accurately positioned so that a particular feature may be added. In the final station, the finished part is cut away from the carrier strip. The web of material left and any punchings from previous stations become the scrap.
Progressive dies are put into power presses that move vertically. As the press goes up the top of the die goes up, and the material advances from one station to the next. Each station is spaced exactly (within fractions of a thousandth of an inch) the same distance apart and the feed is set and pilots are used to advance the material the exact same distance with each progression. Then the press comes down, the die closes, and each station performs the stamping operation. With each stroke a finished part comes off the end of the die.
The cost is determined primarily by the size of the part, number of features (punchings, bends, forms, etc) required, the difficulty of features required, and the accuracy (tolerances) required on the finished part. Generally the closer the tolerances needed, the more expensive the tool is.
