ZrinTech, part of Zhejiang Jinbo Machinery, was founded in 2008 in Henan Province, China. They focus on R&D and manufacture of ultrasonic equipment—such as welding, sewing, punching, and cloth-cutting machines—and control systems for mask production and textile automation.

Sewing/stitching machines – bond fabrics using high-frequency vibrations. Welding machines – for plastics, nonwoven, and electronic parts. Punching machines – cut precise holes/patterns in various materials. Cloth cutting machines – seal and cut synthetic fabrics simultaneously.

It uses high-frequency (20–40 kHz) vibrations to generate heat through friction, melting and bonding materials without thread, adhesives, or open flame. This enables clean, fast, and precise processes.
