20khz Easy Operation Ultrasound Pvc Film Sealer 2kw Ultrasonic Pet Sheet Welding Machine 220V Plastic Welder Principle of ultrasonic plastic welding machineThe ultrasonic energy is transmitted to the welding subject in the process the higher weldment. Due to the massive acoustic resistance at the interface between the 2 welding areas, local hot temperature would be generated. Due to the poor thermal conductivity of the plastic, it's going not to be disbursed in time and accrued within the welding area, resulting in the immediate melting of the touch floor of the two plastics. After adding a undeniable pressure, it's going to likely be integrated into one. When the ultrasonic stops, let the strain final for approximately a seconds to solidify and form, with the purpose to form a solid molecular chain to attain the point of welding, and the welding strength would be close to the power of uncooked materials. Application of ultrasonic plastic welderUltrasonic plastic welding machine is utilized in automobile industry, electronic industry, clinical industry, domestic equipment industry, non-woven clothing, workplace supplies, packaging industry, toy industry, etc. For example, body plastic parts, vehicle doors, automobile instruments, lights, mirrors, sun visors, within trim, filters, reflective materials, reflective spikes, bumpers, cables, plastic filters for motorcycles, radiators, brake fluid tanks, oil cups, water tanks, oil tanks, air ducts, exhaust purifiers, tray filters; Plastic electronics: pay as you go water meter, electricity meter, conversation equipment, cordless telephone, cellphone accessories, telephone case, battery case, charger, valve regulated sealed upkeep lead-acid battery, 3-inch floppy disk, U disk, SD card, CF card, USB connector; Toy stationery: folder, photograph album, folding box, PP hole board, pencil case, ink cartridge and toner drum; Medical every day use: watch, kitchenware, oral liquid bottle cap, drip bottle cap, cellphone accessories, golden comfortable brush, daily necessities, sanitary products, children&;s products, air mattress, clothes hanger, gardening products, kitchen ware, sanitary ware, golden comfortable brush, bathe head, anti-counterfeiting bottle cap, cosmetic bottle cap, coffee pot, washing machine, air dehumidifier, electric iron, electrical kettle, vacuum cleaner Welding of speaker metallic cover, etc commission doesn't include horn by way of sea or air.
