System Qualification

The company first achieved ISO9000 quality system certification in 1993, becoming the second enterprise nationwide to earn this accreditation for its quality management system. In 2005, it successfully obtained the national military standard (GJB) quality management system certification for the first time. Since then, the company has consistently maintained and effectively operated both the GJB quality management system and the ISO9001 quality management system.


Quality Policy


Product Qualifications

Strive for excellence, customer satisfaction

During market development, the company identifies customer needs and incorporates them into the product design phase. Through rigorous control of the manufacturing process, the company ensures that product quality aligns with design specifications. Additionally, by carefully managing the service process, the company guarantees that the product fully meets customer expectations. Finally, leveraging insights gained from these processes, the company continuously refines its approach to ensure products consistently satisfy customer requirements.

Product Qualifications

The company obtained "Factory Approval" from China Classification Society in 1986 and has since successively earned factory approvals from leading global classification societies, including Lloyd's Register (LR) of the UK, Nippon Kaiji Kyokai (NK) of Japan, Bureau Veritas (BV) of France, American Bureau of Shipping (ABS) of the U.S., Korea Register (KR) of South Korea, RINA of Italy, and Russian Maritime Register of Shipping (RS). Our products have also been certified by multiple domestic and international classification societies such as CCS, ABS, BV, NK, KR, and RS. Notably, the WG180/181 hydraulic transmission units for construction machinery have been rigorously evaluated and approved by Germany’s ZF Group, meeting ZF’s stringent industry standards.

INSPECTION SERVICE

In 2010, the "Zhejiang Provincial Testing Center for Fishing Vessel Gearboxes" was established; in 2012, the nation’s first "National Testing Center for Fishing Vessel Gearboxes" settled in HAGG. The establishment of these testing centers has filled the gap in third-party testing for domestic fishing vessel gearboxes, providing scientific, accurate, impartial, and satisfactory testing services and technical support for the national fishing vessel gearbox industry.

The company founded the HAGG High-Precision Gear Testing Center in 2010, covering fields such as geometric measurement, chemical analysis, and mechanical and physical properties of metal materials. It obtained CNAS laboratory accreditation in 2011 (Registration No.: CNAS L5337). Adhering strictly to the ISO/IEC 17025 standard, the center has established a sound laboratory management system, which is continuously improved and maintained for effective operation through a series of management activities. The center maintains exchanges and has established good cooperative relations with multiple authoritative inspection institutions accredited by CNAS or qualified by CMA, including the National Institute of Metrology, Zhejiang Academy of Quality and Technical Supervision, and China NIL Research Center for Proficiency Testing.
