In the landscape of Chinese manufacturing, precision manufacturing has always been at the core of industrial upgrading and quality innovation. As an indispensable key foundational component for injection, die-casting, and stamping molds, the level of high-precision mold base processing directly affects mold lifespan, product accuracy, and production efficiency. Changhui Metal Products Co., Ltd. in Huizhou City, a Chinese enterprise rooted in the industry for over 40 years, has won market recognition with its deep technical expertise and large-scale production capacity. It is now leading the way in the global mold base sector as a "hidden champion."

Changhui's origins can be traced back to Changhui Hardware Co., Ltd., founded in 1986. After restructuring and upgrading in 2009, the company was officially renamed Huizhou Changhui Metal Products Co., Ltd. It is now located in Huiyang District, Huizhou City, covering an area of over 45,000 square meters, with total assets exceeding 200 million yuan. Over 40 years of deep industry involvement have not only allowed Changhui to accumulate extensive process experience but also to develop comprehensive capabilities spanning material reserves, processing, manufacturing, and quality control.

In the field of precision manufacturing, equipment and processes are the cornerstones of quality. Changhui operates over 120 production and processing equipment, including more than 50 advanced CNC machining centers. Its core equipment can achieve maximum travels of 3500mm on the X-axis, 2500mm on the Y-axis, and 1500mm on the Z-axis, with a load capacity of 30 tons, and is capable of deep-hole machining up to 2000mm on a single side. This enables Changhui to not only handle orders for medium-to-large standard mold bases but also flexibly meet the custom needs of various non-standard, large, and high-precision mold bases, such as those for automotive bumpers, instrument panels, LCD TVs, air conditioners, and washing machines.

During the machining process, Changhui strictly adheres to the ISO9001 international quality management system, implementing full-process control from material cutting, rough milling, fine milling, and deep-hole machining to fine grinding. Through a three-stage quality inspection system—"incoming material inspection, in-process self-inspection, and final quality inspection"—and the use of high-precision inspection equipment such as coordinate measuring machines, the company can control key dimensional tolerances within ±0.01mm, ensuring that every mold base achieves exceptional dimensional accuracy, surface finish, and structural stability.

The durability and precision of a mold base are closely tied to its material quality. Changhui maintains a large inventory of forged materials such as P20 and S50C and supplies a variety of high-quality domestic and imported mold steels, including 2738, 718, NAK80, and H13. Its in-house raw material warehouse not only guarantees material quality from the source but also significantly shortens order lead times, providing customers with efficient and reliable supply chain support.

Changhui's products cover various professional mold bases for plastic molds, die-casting molds, and cold stamping molds, widely used in industries such as automotive, home appliances, electronics, cosmetics, and stationery. With a monthly production capacity exceeding 15 million in scale, the company serves prominent domestic clients, including Foxconn, BYD, Hisense, Haier, Huawei, and Y.B.S., while also exporting products to Southeast Asia, Europe, and the United States, demonstrating its strength and credibility in international competition.

Changhui upholds "Quality First, Customer Respect, Service Excellence, and Continuous Improvement" as its core principles, integrating this philosophy into every production process and service system. The company employs over 300 staff, including more than 80 engineering R&D and technical personnel and over 100 CNC technicians, forming an experienced, responsive, and professional team capable of providing customers with end-to-end solutions—from drawing reviews and process design to processing and delivery.

As manufacturing advances toward higher-end and more precise standards, the importance of high-precision mold bases as the "skeleton" of industrial production is increasingly evident. With over 40 years of focus and dedication, advanced equipment, rigorous processes, consistent quality, and sincere service, Changhui has not only become a benchmark enterprise in China's mold base processing sector but also provides reliable precision manufacturing support to global customers. Moving forward, Changhui will continue to uphold its spirit of "continuous improvement and meticulous refinement," collaborating with partners worldwide to drive Chinese precision manufacturing to even greater heights.

Dedicated to providing high-precision, high-performance mold base solutions for the global mold industry.
