TO VIEW MORE OF OUR MICRO CELL SERIES
The parent company, Shenzhen Longood Intelligent Electrical Co., Ltd., was founded in 2001 and successfully listed on the ChiNext board of the Shenzhen Stock Exchange in September 2016. It primarily engages in the R&D, production, and sales of intelligent control systems, intelligent power supplies, brushless motor drives, and new energy products based on applied electronic technology.
Its products are widely used in smart appliances, power tools, lithium battery management, and plant lighting. The group owns four smart manufacturing industrial parks located in Vietnam (Binh Duong), Guangdong (Dongguan), Zhejiang (Haining), and Anhui (Hefei), with nearly 4,000 employees, including over 400 professional R&D personnel. The company has also established multiple professional testing centers, including an EMC laboratory, a lithium battery analysis laboratory, and an environmental laboratory. In the home appliance sector, Longood Intelligent has built solid partnerships with well-known companies such as Joyoung, Aishida, and Supor, giving it strong competitiveness in the small home appliance field.
The focus of this factory audit was Haibo Sensor’s independently developed star product – the MICRO LOAD CELL HB611N-3kg. This miniature weighing sensor utilizes high-precision resistance strain gauge technology, offering advantages such as compact size, high accuracy, fast response, and easy installation, making it highly popular in the market. The product is widely used in small home appliances, smart home devices, vending cabinets, automatic coffee machines, automatic ice makers, and smart rice cookers, providing core sensing support for precise material weighing management in various smart devices. With the continuous expansion of the smart home and automated vending equipment markets, the application scenarios for micro load cells are constantly growing, presenting broad market prospects.
During the audit, the visiting team conducted an in-depth tour of Haibo Sensor’s production lines, quality inspection center, and R&D laboratory. They gave high praise to the company’s comprehensive quality management system, advanced production processes, and strict product consistency control. The two sides held in-depth discussions on subsequent mass supply of the HB611N-3kg product, technical parameter adaptation, and collaborative development of new projects, reaching a preliminary cooperation intention.
This factory audit marks a substantial step forward in the cooperation between Haibo Sensor and a publicly listed A-share company.
Haibo Sensor will continue to be driven by technological innovation, continuously optimizing product performance to provide more reliable and cost-effective sensing solutions for the smart appliance, smart home, and new retail sectors. The company looks forward to establishing a long-term and stable strategic partnership with Longood Intelligent and its subsidiaries, jointly promoting the wider application of intelligent weighing management technology in more fields.
