About Hymson Novolas
Hymson Novolas AG specializes in laser plastic welding (LPW) and develops and manufactures systems for the precise, contact-free joining of thermoplastics. The company traces back to the LPW division of the Leister Group, founded in 1998, and was acquired by Hymson in 2025. The product portfolio includes standalone systems (Novolas TTS, Novolas WS-AT, Novolas WS-AT RTT, Novolas MAXI), modular integration systems (Novolas Basic S/M, Novolas Inline Welder) as well as optics such as LineBeam. Processes include mask welding, Globo-Welding for complex 3D components, 3D-Mask technology and 2µm laser technology. In addition to selling systems, the company offers consulting on material selection and weld seam design, welding tests in application centers, turnkey integration, commissioning, training as well as maintenance and spare parts service. Customers come from the automotive, medical technology, electronics, consumer goods, industrial equipment and packaging sectors. The headquarters is located in Sarnen, Switzerland.
