This product is used to overcome the friction force that occurs in the ejection process, cumulated with the weight of the mould, by magnetically clamping the backplate of the mould, which prevents the mould from falling out of the machine. The parameters that are considered are:
(1) The weight of the mould.
(2) The maximum opening force of the machine.
(3) The clamping force of the movable side is greater than the clamping force of the fixed side because of the acceleration.

No, this system is an electro permanent magnetic system and independent from the electric current. It only uses the electric power for a very short period (0.5 sec) to run the MAG and DEMAG cycle. Then the power drops down. The effective force is generated by powerful permanent Rare-Earth magnets.

No, harmless. After magnetization, the magnetic system forms a closed magnetic field on the surface of the magnetic plate. The effective distance range of the magnetic field lines is 20 mm.
Once above 20 mm, the magnetic field becomes very thin and comparable to the magnetic field strength in the air. So people with pacemakers, bank cards, watches, cell phones and other items should not get close to the magnetic field (20 mm)

No problem at all. By using a multi-layer, waterproof, anti-oil and corrosion-resistant structure, it is even possible to work in water, oil and gas environment.

Depending on the version, the maximum temperature is: T1: 120 ° C, T2: 150 ° C, T3: 180 ° C. At a temperature of> 180 ° C we do not recommend the use of magnetic clamping plates.

The magnetic plate must fit completely against the clamping surface of the mould. Remove any heights, clean the back plate, tighten additional screws, …

A. Branch and model of the machine
B. Closing force (TON)
C. Drawings of the machine clamping plates, dimensions of the centering ring (Only QMC for Moulds)
D. Minimum mold size
E. Maximum mold weight (fixed and movable side)
F. Maximum mold contact temperature.
G. Position and dimension of the scrap removal holes (Only QMC for Dies)

Moulds with the insulation plate on the backplate cannot be used. It is possible if the insulation plate is placed between the backplate and the moulding plate.

Due to the impact, it is possible that the mould is pushed off the magnetic plate. In any case, avoid that the injection nozzle head goes too deep. Use a safety chain during the start-up phase.

The magnetic system has been developed with a safety margin of 30%. So if, for example, the back plate of the mould consists of 20% holes, the system is still intrinsically safe. Keep in mind that other conditions, such as the flatness of the back plate of the mold, also influence the total attraction force of the magnetic plate.

If the temperature of the backplate of the mould exceeds the allowed temperature, an alarm is generated and the automatic production process stops immediately. The solution is to place an insulation plate between the backplate of the mould and the moulding plate.

Yes, when the machine opens too quickly, especially in the first phase, there is a vacuum effect in the mould that can pull it off the magnet plate.

If the mould does not open due to circumstances, the opening force is increased. The moment that the opening force becomes greater than the clamping force of the magnetic plate, the mould will relaese from the magnet plate, and the proximity switch will generate an alarm. The machine will immediately stop.
​When such a situation arises, every precaution must be taken to prevent the mould from falling. For example the use of a safety chain.
