④ Magnet core becomes a strong magnet toclamp the mold.

alnico magnet is not emitted from thesurface of the magnet core so that the moldcan be unclamped.

● Energization is only required when switching on and oﬀ. No energization is required during theclamped state. No electricity is consumed, thus no heat generation.
● The clamp plate has no moving parts, thus assuring high durability. The plate interior is maintenance-

free.
● Clamping force is evenly applied on all faces of the magnet core. No gaps are created between themachineʼs platen surface and center part of the mold which helps improve molding accuracy.
● Once the mold is clamped, unclamping（demagnetization）will not occur even when if a power

outage happens or if power cable breakage occurs.
● Magnetic force of permanent magnet will not decrease through aging. Clamping force is maintained

for long-term use.
● The eﬀective height of the magnetic ﬂux is about 20 mm above clamp plate surface Magnetic ﬁeld

does not cause signiﬁcant eﬀect inside the mold.
● No magnetic ﬁeld is generated from the sides of the clamp plate. So the injection nozzle andcontroller are not aﬀected.

When the mold is displaced or the mold floats above the clamp plate due to a rare mis-set
ejector pin, mis-set nozzle touch, or guide pin getting stuck, the mold dislacement detection
system detects the abnormality and stops the machine immediately. Displacement or liftingof the mold can be detected by the electromagnetic coils that are built in the magnet core
located near the center of clamp plate. When the mold moves, these electromagnetic coils
detect an induction current signal.

This is a cart-type operation panel that can be shared by multiple mag clamps.
Move it to the mag clamp and perform clamping/unclamping operations.

The multi-controller purchased as the first unit can be shared by multiple
molding machines, enabling automation of clamping with only the cost ofa mag clamp plate. The significant reduction in installation cost makes thisdevice ideal for users who have a large number of molding machines with
infrequent mold changes.

Caution in use

Keep away from the magnetic plate when it is magnetized.
● The Mag clamp generates powerful magnetic force. People with cardiac pacemakers are strictly prohibitedfrom approaching the Mag Clamp. The projected height of magnetic ﬂux above the clamp plate on the moldside is just around 20 mm. To avoid damage, do not to bring mobile phones, magnetic cards, compact discs,
or any items that are susceptible to magnetism close to the clamp plate.
● Do not bring any magnetic substances such as ferrous metal close to the adhering surface when the
Mag clamp is at clamping (Magnetized). Magnetic substances may be attracted to the clamp surface
due to the magnetic force, resulting in injury to fingers or hands.

Check point before molding operation● Ejector setting errors can be critical as they can cause the mold to fall. A caution plate is provided for machine
operators so that they can check the mounted position of the ejector pin, stroke, and displacement of the pin
hole.

The surface of the mold plate and magnetic plate must always be clean.
Wipe oﬀ when it is dirty and perform daily visual checks.
● Water, oil, etc. adhering to the surface will not directly cause a decrease in clamping force, but it does make iteasier for dust and foreign substances to adhere to the surface. If there are any dents on the surface, remove
the convexity (bulge) using an oil stone or similar tool. Foreign substances and dents can cause the damage to

Surface, Mold plate

Be careful of mold plate deformation and thickness.
● Do not use a mold with a plate that is deformed or warped. Clamp force can decrease due to the gap
between the mold plate and clamp plate.
● Use a mold plate with a thickness of 25 mm or more. The height of the magnetic force lines protruding
toward the mold mounting plate is approximately 20 mm. If the mold plate is thinner than 25 mm,there is a risk of clamp force decreasing as well as sensor malfunction. If there is no restriction on moldthickness, a mounting plate thickness of 40 mm or more is recommended.
● In the rare case of a 3-plate mold, Pascal recommends increasing the mold plate thickness because magnetic force
may aﬀect the operation of the stripper plate.

$BMDVMBUJPOPGSBUFEDMBNQJOHGPSDF● The clamping force of the Mag clamp（ the adhering force of magnetic clamp ）varies according to the areasize（ number of magnet cores ）where the mold plate and clamp plate are in contact. When loading a small
mold of which mold plate does not contact all the magnet cores, the rated clamping force is determined by

Caution in use

the calculation formula shown below. Refer to the following calculation example.

Magnet core
diameter 78mm

Movable side
Clamp platemodel MRA0100̲M

Mold plate

Example : Clamp plate model MGA0100（ movable side ）1.

Magnet cores that the mold plate contacts with its entire area ＝ 4 pcs

2.

Magnet cores that the mold plate contacts with 1/2 of its area ＝ 8 pcs

3.

Total magnet cores that the mold plate contacts＝ 4 pcs + 8 pcs × 1/2 ＝ 8 pcs

4.

Clamping force per magnet core ＝ 7.0 kN/pcs

5.

Rated clamping force ＝ 7.0 kN/pcs × 8 pcs ＝ 56 kN● If there is a hole or notch at the bottom of mold plate, deduct the respective area from the total contact area
（ number of magnet cores ）● The actual clamping force may be less than the rated force according to the conditions of mold plate.
（ Regarding to the decline of clamping force ）68

%FDMJOFPGDMBNQJOHGPSDF● According to the mold plate conditions for the mold, the actual clamping force may become lessthan the rating. Before using a mag clamp, be certain to calculate and acknowledge the decline ofclamping force referring to the tables and charts below. And be sure to use in the strict condition
that the actual clamping force is greater than the mold opening force of the injection molding
machine.
（Actual clamping force ）=（Rated clamping force - Reduced force ）≧（Mold opening force of the injection molding machine ）● Clamping force decreases according to the material of the mold plate. Also the mold plate that is made of
S45C-H, SUJ and FCD600 material tends to be difficult to detach when demagnetized. This is due to theresidual magnetic ﬂux in the mold. A small clearance between the magnetic plate and mold plate will makeit easiler to detach it.
