Over the course of more than 25 years, ESI has perfected a number of stamping processes in order to better serve your needs. One of those processes is fourslide metal stamping.

A fourslide stamping machine is different from a traditional power press stamping machine in two key ways:

  1. Alignment: It is aligned horizontally as opposed to vertically.fourslide-progressive-die-stampings
  2. More Tooling: As its name implies, a fourslide has four slides; this means that up to four different tools, one per slide, can be used to achieve multiple bends simultaneously.

With a press head attachment the fourslide can also create intricate cuts similar to a progressive die. Power presses can generally achieve the same forming results, however the tooling is more complex and costly.

Each slide of a fourslide is driven by a shaft, which is controlled by the rotations of a cam. Each shaft is connected to its neighboring shafts via bevel gears — one electrical motor powers one shaft, which in turn powers the other shafts.

As material feeds into a fourslide, it is bent in quick succession by each shaft that is equipped with a tool. Feeding, bending, and cutting are all performed in one quick, smooth process, allowing for the high volume manufacture of complex pieces without sacrificing quality.

Fourslide stamping offers a number of benefits over other types of stamping:

High Functionality

  • Fourslide’s multiple tool slides allow for a straightforward process to create parts that require multiple or complex bends, including bends of greater than 90°.
  • Fourslides can also be used to form cylindrical parts, twists, holes, and threaded holes.

Cost Efficiency

  • Fourslide stamping has a number of cost efficiency advantages over other types of stamping. First, the tooling required for fourslide is generally simple and relatively inexpensive, helping to keep startup costs low.
  • Second, the material that is used for a part can often be purchased at the width of the finished product, reducing both material cost and waste.
  • Finally, because multiple bends, folds, punches, or cuts can be performed in a single step, fourslide stamping can often eliminate the need for some costly secondary machining services.
