FAQ – FREQUENTLY ASKED QUESTIONS ABOUT MAGNETIC CLAMPING SYSTEMS
What is the function of a Magnetic Clamping System?
The function of an MCS is mainly to clamp moulds on vertical or horizontal injection and compression presses.
They can also clamp workpieces on machine tools and be used for handling. In general, the function of an MCS is to clamp and release, through an intended command, any object that is made of ferromagnetic material.
The most well-known applications are for clamping workpieces on machine tools, clamping moulds on presses and forming machines, for lifting and handling.
How does a Magnetic Clamping system work?
The magnetic force, generated by permanent magnets, is independent from external electrical energy.
The force depends on external electrical energy only during MAG and DEMAG. During its usage, MCS requires no electrical energy.
Extremely high force generated by internal double magnet circuit
What is the added value of Magnetic Clamping Systems compared to other mould clamping products?
Absence of mechanical equipment (screw, brackets etc.)
Quick mould change independently, without the need of a second operator
More safety for operators
Clean and tidy work area for optimal operation
Quick and flexible mould change
Reduced service time
Utilisation of the entire surface area, optimising the maximum available worktable area
Collection and recording of functional data
Uniformity of the anchoring surface
Reduction of geometric constraints in the mould due to elimination of holes, threads, slots, auxiliaries
What are the typologies of a Magnetic Clamping System?
Field concentration effect
Force evenly distributed over large areas
Well-defined force per pole
High force in large areas
Well-defined force per pole combined with design flexibility High force in large areas
Maximisation of available area
47mm for plates below 12T up to 120°C
55mm for plates above 12T up to 230°C
85mm for heated magnetic plates up to 240°.
Which sectors are covered by Magnetic Clamping Systems?
- Plastic Stamping

- Mould Making
Are Magnetic Clamping Systems Customisable?
Magnetic Clamping Systems are customisable.
What are the working temperatures of Magnetic Clamping Systems?
20 to 240°C in operating conditions.
How much press 'light' is lost by setting up a Magnetic Clamping System?
It depends on the thickness of the magnetic plates.
94mm for 47mm plates
110mm for 55mm plates
170mm for 85mm plates
What is the 'delta T' of a Magnetic Clamping System?
+ – 5, + – 3, + – 2.
What is the Life Cycle of a Magnetic Clamping System?
The magnetic system is highly reliable and long-lasting. If the system is used with care in line with the requirements described in the user manual, the service life is in the order of a decade. Magnetic systems are fully reparable and regenerable, giving the system a long service life.
Partial damage to the systems’ components can occur, which is very sporadic, but they can still be repaired at low cost and sometimes, occasionally, at the place of use.
Also electrical control units are very reliable and long-lasting. Even in this case, any damaged electronic components can be easily replaced.
How do you calculate the ROI of a Magnetic Clamping System?
Number of years amortisation
Annual working days

Is it possible to regenerate a Magnetic Clamping System?
How long does it take to repair a Magnetic Clamping System in case of malfunction?
From 1 to 5 workshop days, plus the two deliveries, or in exceptional cases by the end user.
Are Magnetic Clamping Systems part of the 4.0 Industry?
Yes, through the supply of a dedicated kit.
What security does an Magnetic Clamping System provide compared to a traditional mould fixing?
Significantly a greater and tangible safety as all mould change operations are executed with the operator outside the press.
Can I move a Magnetic Clamping System from a press to another?
Yes, with prior verification and authorisation by RM.
May the mould fall off?
The mould can only fall if the requirements in design, procedures, maintenance and cleaning are not met.
How much maintenance do Magnetic Clamping Systems require?
Very minimal maintenance and surface cleaning.
Is it possible to monitor/control the force of a magnetic clamping system?
Yes, it is monitored through a dedicated kit.
How is the proper functioning of a Magnetic Clamping System monitored?
- Through command and control circuits
- EN280 – EN201
- Active participation in TC270 WG3 for MCS
Does a Magnetic Clamping System qualify for the Machinery Directive?
No, MCS complies with BT and EMC directives.
By how much is the distance between plates reduced for mould installation?
From a minimum of 94 mm to a maximum of 170 mm, depending on the type of MCS.
