In the field of precision manufacturing, the mold base, as the "skeleton" of the mold, directly determines the precision, service life, and production efficiency of the final product. Huizhou Changhui Metal Products Co., Ltd., located in Huizhou, Guangdong, is a leading Chinese manufacturer that has been specializing in the mold base segment for over 40 years, with quench-treated, high-precision mold bases as its core competency.
Professional Heritage, Laying the Foundation for Manufacturing
The predecessor of Changhui can be traced back to Changhui Hardware Co., Ltd., established in 1986. After withstanding market challenges, it was restructured in 2009 into the present Huizhou Changhui Metal Products Co., Ltd. The company is located in Huiyang District, Huizhou City, operating from a modern facility covering an area of 45,000 square meters with a building area of 35,000 square meters. With total assets exceeding 200 million RMB, it is a large-scale mold base manufacturing enterprise integrating R&D, production, and sales.
Advanced Production Capacity, Ensuring Precision Manufacturing
The company possesses strong hardware capabilities and a talented team:
- Equipment Cluster: Equipped with over 120 production and processing machines, including more than 50 advanced CNC machining centers. The large machining centers have a maximum travel of X-axis 3500mm, Y-axis 2500mm, Z-axis 1500mm, with a machine load capacity of 30 tons, capable of meeting the processing needs for super-large mold bases such as automotive bumpers and LCD TV panels.
- Technical Team: Employs over 100 experienced engineers and a workforce of more than 300 people, including over 80 R&D technicians and more than 100 CNC technicians, providing solid technical support for high-precision manufacturing.
- Production Scale: Thanks to efficient manufacturing processes, the average monthly output value exceeds 15 million RMB, enabling quick response to large-volume, high-standard orders.
Core Process: Quench Treatment and High-Precision Machining
Changhui specializes in producing mold bases that possess the core characteristics of high precision, high strength, and excellent thermal stability, achieved through strict material selection and heat treatment processes:
- Material Selection: Maintains long-term stock of forged materials like P20 and S50C, and provides premium domestic and imported mold steels such as 2738, 718, NAK80, and H13, ensuring base material performance from the source.
- Quench Treatment: Through professional heat treatment processes (like quenching), the hardness, wear resistance, and overall strength of the mold base are significantly enhanced. This ensures resistance to deformation and wear under long-term, high-pressure, and high-temperature injection molding environments, greatly extending mold service life.
- Precision Machining: Utilizing numerous CNC machining centers, deep-hole drills (capable of processing deep holes up to 2000mm on one side), and newly added imported CMMs, horizontal machining centers, etc., the company achieves full-process precision manufacturing. From blanking to finish grinding, strict adherence to the ISO9001 quality management system ensures dimensional accuracy can meet high standards within ±0.01mm, satisfying the stringent requirements of industries like automotive, electronics, and home appliances for precision components.
Full-Process Quality Control, Delivering Trustworthy Quality
The company implements the principle of "Quality First, Continuous Improvement" and has established a comprehensive quality assurance system:
- Incoming Inspection: Strict control of raw material quality to prevent defective materials from entering production.
- In-Process Self-Check: Operators perform real-time inspections according to standard operating procedures, with records documented and archived.
- Final Quality Inspection: Comprehensive final inspection using high-precision measuring equipment before shipment, ensuring only qualified products are delivered.
Wide Applications and Market Recognition
The quench-treated mold bases produced by Changhui are widely used in:
- Industries: Automotive (bumpers, instrument panels, lamps, etc.), home appliances (TVs, air conditioners, washing machines), electronics, cosmetics, stationery, and more.
- Processes: Covering professional mold bases for large and high-precision plastic molds, die-casting molds, and cold stamping dies.
- Customers: Has successfully served renowned domestic and international enterprises such as Foxconn, BYD, Hisense, Haier, Huawei, and Yihe Mold, with products exported to Southeast Asia, Europe, the United States, and other markets.
Corporate Philosophy and Future Vision
