★ OPTIMISED FOR SPECIAL GLASS ★ DEVELOPED WITH LEADING GLASSWORKS ★ HIGH QUALITY STANDARDS
The MB7501 butyl extruder was designed to ensure full compliance with the most stringent standards required for the primary seal. The injection capacity (grams of butyl rubber per linear metre) can be set directly using the touch screen control unit. The Butyl rubber is evenly dispensed by two independently controlled extruder nozzles, through two separate dispensers, which ensures an even distribution of the material around the whole perimeter. This independent control and dispensing system is a special feature unique to Forel. The touch screen control unit adjusts both the automatic opening (width adjustment) of the nozzles and the positioning of the pre-extrusion guides, all at the same time in a single operation, according to the selected spacer width value. The machine is able to apply butyl rubber on shaped (curved) profiles or Georgian bar frames, with exceptional accuracy and simplicity of operation. The machine also features a system to allow for vertical adjustment of the nozzles position, so that extrusion height can be varied for processing special profiles. The number and correct distribution of resistance heating elements inside the circuits allows for a fast restart after changing the butyl rubber. Preproduction heating can be pre-set to automatically turn on.
