^{Electro-Permanent Magnet Die
Clamping}

TECNOMAGNETE - These magnetic modules, based on Quad-Press technology, are designed expressly for mold clamping on metal stamping presses. Quad-Stamp is provided with a specific magnetic layout and neutral areas for scrap removal.

The system includes a proximity switch to ensure the die is within 0.007 inches of the bolster or ram surface before clamping is allowed. The system uses as little as 1 3/8" (35 mm) of shut height per plate on smaller presses and 2 1/8 inches (54 mm) of shut height per plate on larger presses. The magnetic flux generated in Mag phase penetrates the die for 0.8 inches (20 mm) at a controlled depth, enabling it to hold it in safely without interfering with parts inside the die. The 3.15 x 3.14 inches (80 mm x 80 mm) poles hold 2,200 pounds (1,000 kg) per pole while the optional smaller poles hold 770 pounds. The Quad-Stamp cannot overheat and is not affected by electrical interruption.

^Advantages:

^{No need for Common Die Shoes}
^{Universal Clamping - Quick and
Versatile}
^{No Die Sagging - High Force (constant
and infinite)}
^{No Die Modifications}
^{Easy Installation}
^{No Maintenance}
^{Quick Die Release (1 to 4 seconds)}
^{Shorter Die Changes}
^{Increased Uptime}

^{Fail Safe:}

Loose of power has no affect on the holding power of the TECNOMAGNETE Quadsystem
The TECNOMAGNETE Quadsystem is tied into the presses E-stop circuitry
^{Two handed system switches magnet's
poles "permanently". The permanent-electro magnet can only be turned off
(poles reversed) if power is applied again.}
TECNOMAGNETE has two control choices to do this:
- ^{Turn keyed switch (spring return)
  simultaneously while pushing a button}
- ^{Touch screen controller requires
  operator to enter a code and then push two buttons}
Optional - TECNOMAGNETE control system to give real time holding force feedback

The QUADSYSYTEM patented technology

A QUADSYSTEM is featured by a combination of reversible magnets (blue) on the base of each magnetic poles + "power" magnets (red), surrounding the poles (yellow).
This structure generates a working surface creating a multiple magnetic stitching, thus granting a perfect clamping of any work piece.

The double reversible magnet characteristic allows the QUADSYSTEM chuck to move the internal magnetic field outside, thus activating the working surface.

DEMAG phase- "OFF" position

During the DEMAG phase the magnetic flux is short-circuited inside the chuck.
No residual magnetism is present on the chuck surface.

Zero power consumption.

ON/OFF procedure

With the simple touch of a button is possible to energize (MAG PHASE) and de-energize (DEMAG PHASE) the magnetic field.
After this operation, the connection can be removed and the electrical supply is no more used.

MAG phase - "ON" position

The chuck will keep the work piece/mold/load safely clamped for an indefinite period of time with 100% strength.

Zero power consumption.
