Ultrasonic plastic welder is the professional machine for plastic welding. The work theory is adopting ultrasonic plastic welder's high frequency vibration, makes the two materials' surfaces to melt and weld together soon in 0.1-2 seconds under certain pressure, then finish the whole welding process. This machine has the advantages of not adding any additives, no pollution; high speed, high intensity; no trail leaves on welding surfaces, beautiful exterior and so on. This machine is widely used in electronic product, car, electrical appliance, toy, stationary, lighter, household articles, package, and weaving industries. Features 1) Germany chip energy transducer, high efficiency 2) Amplitude titanium alloy rod, infrangible and durable 3) Electric motor elevation and subsidence, labor-saving and convenient 4) Double-ended cylinder position, eliminate twisting moment 5) Adjustable parallelism of welding head, adjust mould fast and conveniently 6) Frequency demonstration, convenient detection
