Large reduction in mold changing time !
Shorter Mold Changing Time
① With a manual clamping system, workers must loosen and tighten bolts one by one. However,
with an automatic clamping system, a single operator canrelease the clamps holding the mold on
both sides at once,reducing changing time.
② Reduction of mold changing time results
less time the crane spends waiting to put

the mold in place, an important factor at
plants where multiple molding
machines are in operation.
③ When there is an urgent need to repair a mold, the
automatic clamping system can reduce down time by
allowing faster dismounting and remounting of the
mold.
④ Reduction of mold changing time leads
to an overall improvement in productivity.

It is very easy to clamp and unclamp a mold.
You just need to press the LOCK or RELEASE.
The MEK series dramatically facilitates mold
mounting/dismounting work.
The mold is clamped just by pressing the
LOCK button. NO need to move to the
counter-operation side and use a wrench or
other tool.
Hard work such as fastening bolts is also
reduced.

Start magnetization after closing mold
The polarity of the alnico magnet
wrapped around the coil is reversed
when the electric current is supplied,
shifting the magnetic flux.
This operation generates magnetic
force on the surface of the magnet
block.
The magnetic force becomes permanent.
During molding production
The magnetic flux will be permanently
maintained unless an electric current
is supplied. During production, power
is supplied only to the proximity switch,
so there is almost no energy consumption.

Safety
The degree of adhesion has been improved
by making the plate surface (clamping part)
one plate due to the degree of flatness .
Mounting bolt holes
The plate uses existing holes in
the platens, or holes can be tapped
during installation.
High rigidity of plate
By making the magnet applied part columnar,
the machine gets poles between magnetic
poles, and the rigidity of plate has been improved.

Cautions
● Notes for design
1）Check the specifications.
③ Multiply the clamp force of each magnetic block（6.27kN /
● Please use each product according to the specifications.
● The operating temperatures of magnetic plates (on mold
contact surface) are 0 ∼ 120℃.
unit）by the total number of units.
Rated clamp force
※1
＝6.27kN / unit×9 units＝56.43kN
※1. The above calculation is for ideal conditions between the magnetic
plate and the mold.
Note, however, that if the temperature exceeds specifications
the attractive force will drop and will not be restored even if
the temperature is returned to the normal range.
※ If that happens, stop production, suspend the mold from a crane and
re-magnetize the clamp after demagnetization.
1. If there are holes or notches on the rear surface of the mold mounting
plate, subtract the area from the contact area（no. of magnetic blocks）
with the mold mounting plate.
2. Actual clamp force may be reduced due to the conditions of the mold
mounting plate.
2）Rated clamp force calculation method

A smaller mold decreases the clamp strength.
If the mold mounting plate does not contact all the magnetic
blocks, calculate the rated clamp force ※1 referring to the
following calculation example.

If the material of the mold mounting plate is S55C, S45C, or

SUJ, etc., the mold may be difficult to release when the clamp
is turned OFF. This is due to residual magnetism.
Magnetic strength decreases with increasing gap between
the mold mounting plate and magnetic plate.
Take caution regarding this issue during use.
● Influence of the roughness of the mold mounting plate
The roughness of the mold mounting plate decreases force,
as indicated in the following table. Confirm the roughness of
the mounting plate.

① An error in the ejector force setting may cause the mold to
accidentally drop.
● When the ejector force（ejection force and speed）
exceeds the clamp force, the mold is pushed by the ejector
pin and falls.
Setting target ：
Ejection force ･･･ Less than 1/3 of the
movable platen clamp strength
Speed
･･･ Less than 50mm/sec
● Check for errors in ejector pin length or misalignments
in the location of the holes.
● Use a crane to suspend the mold to remove and insert
ejector pins.
② When the mold opening force exceeds the clamp force,
the mold drops.
● Ensure that the mold opening force does not exceed the
clamp force. It is recommended that measures to prevent
the mold from falling should be taken to prepare for an
accident, in the event of an abnormal mold opening
force.
③ When an overweight mold, exceeding the clamp force, is
used, the mold will drop.
④ Use a clamp force that exceeds twice the nozzle touch force.

8）Ensure that the contact surfaces of the magnetic and mold mounting
plates are always clean. Although water and oil on the contact surface do
not directly cause the clamp capacity to decrease, dust and foreign

the magnetic and the mold mounting plates.

appropriate.
Take into account a balance in the front-back direction.
10）When using ejector pins, always check to ensure the proper pin length and
