We have taken the standing seam machine to a whole new level. While being a fully automatic machine equipped with all features, it also stands out for its compact size and light weight. In this way, it does not take up unnecessary space in the workshop and there is no need for large vehicles to transport it to the job sites. Thanks to its light weight, it can be eaasily carried anywhere. Faster, more precise and easier to use... It produces 25 mm seam high standing seam metal from coils or sheets in a single pass. Eave and fascia claddings are also produced quite easily and quickly. Bledpfx Ahe Abbmiedjp Both Modes are on the same machine! Automatic Mode: The lenght of the panel to be produced and quantity are entered into the digital screen. Once the desired dimension is reached, the machine automatically performs the cut using a guillotine shear and continues production. There is no need to wait by the machine. It is sufficient to simply collect 25 mm seam-height metal panels as they emerge from the machine. The machine will stop operating once the specified quantity has been reached. Semi-Automatic Mode: The material inside the machine reaches the desired lenght and stops. Cutting is performed using a motorized guillotine shear by pressing a button. Afterward, the machine continues the production process with the press of a single button. Once the specified quantity is reached, the machine stops operating. It features roll-forming rollers made of high-quality steel with corrosion protection. It is a cost-effective, long-lasting and trouble-free machine that offers a sustainable solution and maintains its quality for many years without requiring additional expenses. A brand that stands ready to provide support at any moment - with an extensive and robust inventiory of spare parts and a team of expert sevice employee - guaranteeing that your operations never come to a halt: Wide spare parts inventiory, rapid service.
