Import Auto Ultrasonic Plastic Welding Machine — Buy in Bulk from Supplier in China

The CN-2015, CN-2615 and CN-3215 models are auto ultrasonic plastic welding machines designed for high precision joining of thermoplastic components, delivering welds that meet waterproof and airtight requirements. Each unit operates at 15 kHz frequency with pneumatic drive, stroke of 70 mm and output time adjustable from 0.1 to 99 seconds. The machines support power outputs of 2000 W, 2600 W or 3200 W respectively, with max input power of 1.2 kW and air pressure demand of 0.6 MPa.

These welders handle a broad range of plastic materials including ABS, PS, PP, PE, PC, PVC, nylon, polyacetal and polysulfone, using interchangeable tooling to adapt to different workpiece shapes. The frame is constructed from alloy steel to maintain stable frequency, and the welding area measures approximately 200 mm diameter. Standard industry practice for ultrasonic welding includes verifying weld strength via tensile tests and ensuring consistent amplitude across the horn, which is typical for high volume production environments.

Applications span toy manufacturing for items like gun casings and doll parts, electronics for watch cases and mobile phone batteries, automotive lighting for rear and cornering lamps, packaging for cosmetic boxes and PVC containers, and commercial products such as typewriter ribbons. Buyers typically source these machines for small to medium batch production of single species plastic workpieces, with the option to adjust parameters for custom requirements.
