Company History
Guangdong Hongze Intelligent Technology Co., Ltd. (formerly Dongguan Hongze Intelligent Technology Co., Ltd.) was founded by Wu Encai on May 3, 2017.
Wu Encai studied at Hunan Mechanical and Electrical School in 1994, where he taught himself CAD drafting. In 2000, he moved to Guangdong, accumulating technical and operational experience in a Hong Kong-funded enterprise and a small household appliance factory successively.
Through a casual conversation, he came into contact with the concept of "window openers" and Sensitively detected market opportunities. In 2006, he focused on the intelligent window opener track, devoting 16 years to it. He led his team to overcome technical difficulties and obtained more than 30 patents. At the end of 2009, the first set of window openers was mass-produced. The urgent order of over 2,000 units for Tianjin Convention and Exhibition Center was delivered within a month, laying a solid foundation in the market.
Nowadays, the factory sells 300,000 to 400,000 window openers annually, covering manual to fully automatic models. Since its establishment, the company has expanded its product range to include intelligent ventilation and smoke exhaust heat release window control systems, intelligent skylight control systems, and electric sunshade blinds, forming four categories, over ten series, and hundreds of products. These products serve large-scale places such as office buildings, airports, and stadiums. By introducing advanced technologies from Germany and Italy, adhering to the ISO9001:2015 quality management system, and having its products pass authoritative fire safety tests, the company has built an integrated capability of "design, production, and sales", establishing a solid reputation and a distinct brand image.
