BT-28K Seamless Bonding Machine Ultrasonic Seamless Sealing Machine for Seamless Underwear, Sportswear, Outdoor Wear

The BITOP BT-28K ultrasonic seamless bonding machine joins and seals high-elasticity fabrics with 28 kHz ultrasonic energy instead of thread, giving a soft cut edge with no thread break and no damage to the fabric, so the material keeps its stretch. It runs continuously at 1-25 m/min at 1000 W, with jog and self-locking modes. A PLC touch screen with digital frequency tracking keeps output stable, and a double stepper motor drive allows differential speed adjustment, so parameters can be tuned per material. The 52 mm x 10 mm pattern roller is easy to replace, and custom patterns are available. Used for seamless underwear, sportswear, swimwear, outdoor wear and bulletproof vests. AC 220 V 50-60 Hz, air pressure 0.35-0.5 MPa. Supplied new from Zhejiang, China with a one year warranty on core components.
