Italian-based company Tecnomagnete with 40 years of experience in the field of industrial magnetism and its Russian distributor, Solan-D introduce innovation – permanent electro magnetic system HotMag
The new permanent electro magnetic system HotMag is the final answer to all the needs to make quick change operations on press machines working with high temperature moulds. The innovative magnetic circuit, made of special solenoids and high energy permanent magnets, allows to operate with temperature up to 250° C. The full metallic surface allows the perfect stability and uniformity of clamping all over the contact area granting high performances in the long run. The permanent electro technology is intrinsically safe. No electrical supply is required during operation thus the system in insensible to any power breakdown. As a consequence there is no consumption and no heat generation. The magnetic area, surrounded by the neutral crown, is composed of circular alternated North and South poles generates a powerful magnetic strength concentrated in the central parts of the modules thus allowing to achieve the maximum performances with any type of mould. The patented electro permanent technology allows to concentrate the magnetic flux only on the area in contact with the mould. Every circular pole generates a permanent and constant clamping force of 200 Kg each pole that translates into a clamping force of 2.8 Kg/cm2 on the magnetic area in contact with the mould. As an example a mould with a contact area having a diameter of 500 mm is clamped with a force of 5.500 Kg Uniformity of clamping is the main advantage of Technomagnete’s technologies. It ensures high repeatability of the moulding quality and extending the mould life. Equipment comes together with electronic controls. The ST 200R control unit can make quick magnetisation and demagnetisation cycles. The remote control permits to operate always at a distance from the hot working area. The special Nuflux system built inside allows to get rid of any residual magnetism on the mould surface even when highly alloy materials are involved. HotMag can be characterized by the following: Quick – few seconds only to activate and deactivate the system. Simply pushing a button! Ergonomic – the operator that can remain always at a distance from the mould, avoiding the risk of injuries. Easy and practical – no modification to the machine, no modification to the moulds and no special tools are required. Time saving – the mould can be preheated outside the machine magnets will hold the mould at indefinite period of time. Safe – only the high strength generated by the permanent magnets will hold the mould at indefinite period of time. Convenient – the low investment and the high efficiency grants a quick pay back. Quick and flexible – the mould-change time is dramatically reduced. The procedure consist of just several simple operations 1 Insert the mould 2 Close the press 3 Magnetize in the same time upper and lower module 4 The mould is clamped and aligned: the machine is ready
