This range of ultrasonic welders brings absolutely top quality welding within the reach of all blind manufacturers. Our ultrasonic welder does not require any additional substrate inserting between the plies. Virtually all of our fabric in the UK is polyester based and this is perfect for welding ultrasonically, this is not a heat welder. This particular machine has also been specifically designed so that you can do straight welding and three sided for sealed in bottom weights, they look superb. No needle holes. The weld time is only about 1 second and the handling has been made as simple as possible. It gives you an absolutely superb finished product. Comes as standard with guides and left hand stack clamp. Available in 90mm widths (but it is possible to produce 130mm slats on this machine too). Includes the Bambi silent compressor.
