Suzhou Hengkuai Laser (ECO2 Laser) Co., Ltd., established in 2017, is a wholly-owned subsidiary of Suzhou Tianhong Laser Co., Ltd. It specializes in the research and development, production, sales, and service of carbon dioxide (CO₂) laser tubes. The brand was formerly known as JK LASERS, a division of the UK-based GSI. Its CO₂ glass tube business was first acquired by SPI, a subsidiary of the Trumpf Group, in April 2015, and subsequently sold to Suzhou Tianhong Laser Co., Ltd. in October 2015.
After two years of technical development, in 2017, Suzhou Hengkuai Laser Co., Ltd., as a new manufacturer, revived its CO₂ laser business—which had a 40-year brand history—and further developed the HLC and ELC series of laser tubes to meet market demand.
The company has retained the technical team from the former GSI CO₂ Division, as well as its advanced manufacturing processes—including gas filling and physical vapor deposition—commissioning technologies, and quality standards. As a result, the products deliver outstanding performance in terms of spot size, spot quality, and cutting speed, and are widely sold globally in industries such as advertising, apparel, footwear, automotive, aircraft manufacturing, electronics, and semiconductor manufacturing.
