  • Electromagnetic Hot Melt Guns

    STRAIN 121 electromagnetic guns are the most sophisticated, innovative, and technologically advanced on the world market today. They stand out from their competitors due to their speed, compactness, precision, repeatability in supply, ease and speed of installation, as well as being completely noise free. They are particularly suitable for applying and supplying micro-points of thermal adhesives even at very high speeds of up to 5,000 Cps. They can reach a cycle speed of less than 1 millisecond and an overall lifecycle of tens of millions of strokes.

    The electrical kit is easy, quick, and safe to extract.

    A precise micro-regulation system guarantees simple, perfect formation of micro-points of glue, even at very high speeds.

    This makes it possible to supply a glue point in less than 1 millisecond, with maximum repeatability.

    An innovative energy saving system makes it possible to recover up to 50% of the electricity used for the gun to operate.

    All the gun’s components are assembled inside the casing, which makes maintenance easier and reduces the quantity of spare parts required.

    The material used to make the gun casing is “Ergal”, which significantly improves performance in terms of strength to resist mechanical forces. A hard oxide coating makes cleaning and maintaining the gun quicker and simpler.

    Easy to access and replace, it ensures a better distribution of the adhesive preventing the nozzle clogging due to the presence of impurities in the adhesive. It is integrated and easy to change.

    The nozzle is made of special high strength material and guarantees maximum repeatability, exceptional reliability, and very high precision, as well as uniformity of the micro-points of glue deposited.

    The STRAIN DRIVER 121 digital control unit runs up to 2 guns fully independently for all functions and allows repeatability that far outstrips normal applications, thanks to its innovative electronics.

    A terminal board with a rapid coupling connector on the back of the unit is used to connect all the Input and/or Output signals and the photocells required for the system to operate properly.

    It displays graphically the sections and the programmable parameters allowing a very easy way to program the guns even by non-specialist personnel, eliminating problems generated by codes and foreign languages.

    An innovative selector with built-in button controls the programming method of all the operating parameters: every time the knob is pressed, another parameter appears, which is increased or decreased simply by turning the knob.

    4 leds show the system status and any alarms or faults that arise while the unit is operating.

    Once the control unit has been programmed, the data entered can be protected by using the safety key located on the front panel.

  • Preo module icon

    The modules of the AMX 45 Series (interchangeable with the previous series New Life), are the first and only in the world equipped with a double interchangeable gasket cartridge. They are the most innovative product actually present in the world market. Thanks to its technology deriving from the aerospace and aviation sectors, PREO developed this component of crucial importance for the whole system; its main aim, that cannot be detected in no other module of our competitor, is the high and innovative mechanical technology peculiar of its design and manufacture. In addition, its small size, high speed of work (up to 6,500 strokes per minute), precise application and easy maintenance make it reliable, cost-effective and long lasting. A wide range of models enables even the most demanding Customer to always find the best solution to any gluing problem.

    The innovative system of interchangeable double gasket cartridges (specifically designed and manufactured) ensures perfect tightness even under conditions of high pressures and at high temperatures, requiring minimum maintenance, at the same time being cost-effective, handy and durable. Actually, the cartridge holding the gaskets needs only to be unscrewed and replaced with a new one, which is already pre-assembled on its housing, to have a perfectly working module, without jeopardizing its reliability, quality and performances.

    The modules are currently supplied with nozzles provided with the Zero-Cavity locking system, whose main feature is that of being self-cleaning, as the lock acts directly on the hole of the nozzle, shattering possible impurities and ensuring that the nozzle is always clean for the proper working of the whole system.
    An extremely wide range of nozzles including different patterns and special performances based on the specific needs of the Customer both in relation to the size of the application area and the kind of material used during construction.

    The body of the module is manufactured of brass, a material significantly improving the performances in terms of thermal conductivity and mechanical stress resistance. An outer nonstick hard-oxide coating makes cleaning and maintaining the gun easier and faster and reinforces the casing itself. A complete model range allows the Customer to choose the most suitable module according to the requested application.

    The AMX-45 NL Series, interchangeable with the previous series NEW LIFE, is mainly used for applications with a maximum speed of work up to 6.500 cycles/minute.

    The AMX-45 LL Series, interchangeable with the previous series Long Life, is mainly used for applications with a maximum speed of work up to 4.000 cycles/minute.
