Eighteen Zhongshan enterprises have earned provincial-level "manufacturing single champion" titles for their specialized products, as announced in the list by the Department of Industry and Information Technology of Guangdong Province.

The selected companies span both traditional strengths and emerging sectors. Traditional leaders include Mingmen Lock and Horisun Group, while strategic innovators feature Belling Bio and Hongjing Optech. This mix highlights Zhongshan's dual thrust in upgrading competitive industries and nurturing high-growth sectors such as biomedicine, new materials, and optical electronics.

The certified products exemplify technological prowess: space-grade gallium arsenide solar cells, panoramic camera modules, wide temperature range precision sensors, and high-purity indium oxide/silver alloy targets for displays. 

Notably, Uniwatt, developer of the space-grade gallium arsenide solar cells, has over 10 years of deep expertise in aerospace vehicle propulsion and energy systems. Its products have powered China's Tianzhou-6 cargo spacecraft and Pakistan's scientific satellites.
