ASTRO hot-wedge welding machine with high speed guarantee
Time is money. By no means a new discovery, especially in regard to welding geomembranes. That is why the factor of welding speed is the subject of such close scrutiny when it comes to procuring the right hot-wedge welding machine.
ASTRO’s user-friendly operation is apparent at first glance. Two functions may be performed at the same time with ease, namely pressure regulation together with the wedge advancement to the desired welding position. Both positions are immediately identifiable and enable economic operation.At welding speeds up to 5 meters per second with perfect welding quality, ASTRO is the top machine worldwide. Continuous regulation of the joining pressure setting comes as standard for LEISTER machines, as does joining pressure compensation of the feed rollers by means of the pendulum head. This in turn leads to simple and error-free welding of T-joints. The ASTRO hot wedge machine enables welding of geomembranes in foundation engineering work with 1.5 – 3.0 mm PE-HD materials. All these factors serve to persuade the user and thanks to the worldwide reputation for reliability enjoyed by Leister products; the result is economical welding of the volume of material to be processed on the construction site.
