—- Accurate Forming: Deep Draw Metal Stamping Fundamentals, Part 2

The blank for the part to be drawn is removed from the strip and moved into the transfer slide. The transfer slide carries the blank to the first draw operation or station. At this station the blank is drawn to its first shape. The transfer slide then returns to its original position and is now ready to accept the next blank.

Once the transfer slide is in position to receive the next blank, fingers that are attached to the slide now position themselves to move the next blank to the first station. At the same time the first blank which was formed to its initial shape is moved from the first station to the second. This process is repeated until the slide is filled and every station has a part in it. Once the stations are full every revolution of the press produces a completed part.

As the machine continues running heat is generated during the drawing operations stabilizing the tooling which helps with the flow of the material. When a drawn part is completed through the last station of the press, the part is work hardened and subsequently harder than the original strip of material due to the working/compressing of the material.

Accurate Forming is a Deep Draw Metal Stamper who was established in 1955. All of Accurate Forming’s operations take place in our 70,000 square foot facility located in Hamburg, NJ. Accurate Forming manufactures cylindrical shaped parts using transfer press technology. The size range for these parts ranges from .700” in length with a diameter of 1.562” all the way to 5.44” in length with a .400” diameter. Material thicknesses range from .007” thick up to .062” thick. Materials that are used in the deep draw manufacturing process are aluminum, cold rolled steel, pre-plated crs, stainless steel, copper, brass and other precious metal alloys.
