30K Ultrasonic Lace Sewing Machine

Specially optimized for lightweight disposable textile processing, this 30K ultrasonic lace sewing vibration unit creates neat waterproof lace seams for mask packaging, isolation gown edges and cosmetic nonwoven pouches. Higher 30kHz frequency achieves finer sealing lines than 20K/28kHz models, protecting fragile thin nonwovens from damage. Modular split design allows fast disassembly and roller mold switching, supporting 8-hour non-stop daily mass production. Small footprint fits compact workshop automated lace welding assembly lines.   Working Principle   For delicate disposable fabric processing, the 30K Ultrasonic Cut and Seal Machine (ultrasonic lace sewing machine) adopts refined high-frequency vibration transmission logic. The built-in Ultrasonic Transducer outputs mild yet sufficient vibration energy to thin PP nonwoven, melt-blown cloth and polyester composite materials. Custom circular roller Ultrasonic Welding Mold distributes vibration force evenly across fabric surfaces, c…
