Hymson Novolas AG has nearly 25 years of technical heritage originating from the laser plastic welding (LPW) division of Leister AG. Acquired strategically by Hymson in 2025, it embodies Swiss craftsmanship and globally patented welding technologies. Backed by Hymson’s automation expertise and global network layout, it provides professional services for high-end sectors including automotive, medical devices and electronics.
Leister Group founded its dedicated laser plastic welding division.
Pioneered industrial mask welding technology enabling precision at hundred-micron level, winning the prestigious Swiss Technology Award 2000.
The innovative Globo-Welding technology was launched to overcome bottlenecks in complex 3D part welding, winning the Swiss Technology Award once more in 2004.

Launch of Novolas Basic Modular System
The first Novolas Basic modular system was put into application. The Basic series was iteratively developed and launched from 2008 to 2024.
The Novolas WS-AT was originally launched as a versatile modular laser welding system.
The desktop Novolas TTS laser plastic welding system was launched, featuring high efficiency and compact structure.
Initiated joint development of 3D Mask technology alongside customers for customized projects.
The development and practical application of 2-micron laser technology was initiated.
The MAXI dedicated welding system for large components was officially released.
Hymson took over Leister’s laser plastic welding business to inherit core technologies, drive continuous innovation and sustain consistent premium product quality.

Launch of Inline Welder Integrated System
The Inline Welder integrated system is launched for seamless integration into diverse production lines.
Our brand-new facility goes online to sustain premium service and reliable support for partners worldwide.
Laser Plastic Welding has established itself worldwide through its outstanding performance and application-specific solutions. Highly innovative markets such as the automotive industry and medical technology are increasingly opting for laser welding of plastics.
Laser energy is applied without physical contact with parts, preventing scratches and fixture wear during processing.
Flexible weld joint layout lowers pre-processing requirements and total machining expenses.
The weld bead is smooth and uniform, requiring little or no post grinding and polishing work.
Concentrated laser energy creates a narrow heat-affected zone to cut thermal deformation; no clamping pressure avoids mechanical residual stress.
No filler material or flux is needed in welding, leaving no impurities and satisfying high-cleanliness production requirements.
Micron-level positioning ensures ultra-precise welding, while tight metallurgical bonding delivers excellent joint tensile and shear strength.
