Ningbo Haoyuan Automotive Parts Co., Ltd. was established in 2003, initially focusing on plastic mold design and manufacturing as its core business.
Leveraging precision machining technology and rapid market responsiveness, the company quickly established a solid foothold in the industry.
As global manufacturing demand shifted toward lightweight and high-performance materials, the company underwent a strategic transformation in 2008, pivoting to aluminum die casting.
It gradually evolved into a comprehensive aluminum die-casting solutions provider integrating R&D, production, and sales.
Over its 22-year development journey, the company has consistently driven innovation, transitioning from traditional mold manufacturing to advanced aluminum die casting.
In 2010, Haoyuan formally concentrated on die casting, introducing L.K. die-casting machines and establishing integrated production lines for melting, die casting, and post-processing.
Emphasizing technological advancement and quality management, the company has obtained certifications including ISO 9001 (Quality Management System), IATF 16949 (Automotive Quality Management System),
and ISO 14001 (Environmental Management System). Its products are widely used in automotive, gear reducers, medical equipment, road lighting, and other fields.
