Electro-Permanent Magnetic Quick Die Clamping System

The electro-perm system does not use power once energized so a loss of power does not cause a loss of holding force. The technology, a safe and reliable magnetic circuit, is widely used on work holding, material handling, and mold / die clamping.

The same, practical technology is used in metal stamping presses. The advanced double magnet circuit is composed of square poles machined into a solid block of steel. Each pole generates a constant, uniform and predefined force regardless of who turns the system on. This force is proportional to the number of poles in contact with the die surface.

This system does not magnetize the entire die, the magnetic flux penetrates the die only 20 mm deep. The die face and part cannot become magnetized, allowing for scrap removal, and proper die operation without interference. In a few seconds with the simple press of a button, it is possible to clamp or unclamp the die in complete safety. Even during a power failure, the system remains operative, with constant clamping force.

This uniform clamping force allows repeatability and constant quality process by eliminating any flexing of die shoe.

This system is suitable dies of any shape and size, with no modification. Die standardization is not necessary: savings in engineering time and overall cost.

Locating devices are easy to add, scrap holes can be used, bolster extensions can be added. Dies on parallels can be held with the special parallel pole design T-slots in the lower can be added to enable a wide variety of die lifter configurations.

One operator, with no tools, can operate all the die-clamping procedure easily and in total safety, outside the press.
