About
our company
Guangdong Hongze Intelligent Technology Co., Ltd. (formerly Dongguan Hongze Intelligent Technology Co., Ltd.) was founded by Wu Encai on May 3, 2017.
Wu Encai began studying mechanical and electrical engineering in 1994 and taught himself CAD drafting. After moving to Guangdong in 2000, he built extensive technical and operational experience in Hong Kong-funded manufacturing and the small household appliance industry.
A chance conversation introduced him to the concept of window openers—and revealed a promising market opportunity. Since entering the intelligent window actuator industry in 2006, he and his team have remained focused on solving technical challenges and building reliable automation systems.
The first Hongze window openers entered mass production at the end of 2009. Soon afterward, an urgent order of more than 3,500 units for the Tianjin Convention and Exhibition Center was delivered within one month, establishing a strong foundation for the company’s growth.
