In the field of precision manufacturing, the mold base serves as the "skeleton" of the mold system, carrying core components such as cavities and cores. It directly determines the precision, quality, and production efficiency of the final product. Especially in the manufacturing of large-size, high-precision mold bases, the integration of technology, equipment, and experience becomes a key measure of a company’s core capabilities. In the wave of China’s transition from "made in China" to "quality made in China," a group of specialized manufacturers with decades of industry expertise are becoming indispensable forces in the global supply chain, thanks to their dedication to technology and quality. Among them, Huizhou Changhui Metal Products Co., Ltd. (hereinafter referred to as "Changhui") stands out as a leading representative in this field.
1. Four Decades of Focus on Mold Bases: From Foundation to Benchmark
Changhui’s history can be traced back to Changhui Hardware Co., Ltd., established in 1986. For over forty years, the company has remained dedicated to the research, development, and manufacturing of mold bases. In 2009, after restructuring and renaming to Huizhou Changhui Metal Products Co., Ltd., the company entered a new phase of scaled and systematic development with the support of Shenzhen Jishengchang Industrial Co., Ltd. Located in Huiyang District, Huizhou City, the company occupies an area of over 45,000 square meters, with modern factory buildings spanning 35,000 square meters. With total assets exceeding 200 million RMB, Changhui has become a mid-to-large-sized backbone enterprise in China’s mold base industry.
Over the years, guided by the principles of "customer first, quality foremost, service excellence, and continuous improvement," Changhui has continuously deepened its expertise in technology and craftsmanship. The company has established significant advantages in the manufacturing of mold bases—the foundational components of molds—making it the preferred partner for many well-known enterprises and earning the reputation of a "hidden champion" in this specialized niche.
2. Why Are Large-Size, High-Precision Mold Bases So Important?
In molding processes such as injection molding and die-casting, the mold base acts as the supporting framework for the entire mold. Its role is not only to secure components like cores, guide pillars, and ejector pins but also to ensure the mold remains stable, precise, and durable under high-temperature, high-pressure, and high-frequency production environments. This is particularly critical in industries such as automotive, home appliances, and large electronic devices, where products feature complex structures, large dimensions, and stringent precision requirements. Correspondingly, the mold bases must possess:
- High rigidity and large load-bearing capacity: To prevent deformation or cracking under long-term high-pressure injection.
- Exceptional dimensional and fitting precision: To ensure minimal dimensional deviations in the final molded parts (as tight as ±0.01mm).
- Excellent thermal stability and wear resistance: To withstand high-temperature materials and continuous production environments.
- Good machinability and adaptability: To support the design and implementation of complex mold structures.
Changhui has built comprehensive capabilities across the entire chain—from materials and equipment to processes and quality control—to meet these core requirements.
3. Changhui’s Core Manufacturing Strengths
1. Advanced Equipment Cluster for Large-Size Processing
The company operates over 120 precision machining equipment units, including more than 50 CNC machining centers. Among these are multiple large-scale gantry machining centers with maximum processing ranges of up to 3500mm on the X-axis, 2500mm on the Y-axis, and 1500mm on the Z-axis, with a load capacity of 30 tons. Deep-hole drilling equipment can achieve single-sided drilling depths of up to 2000mm. These capabilities enable the production of large automotive mold bases (e.g., for bumpers, instrument panels, and headlight/taillight housings), TV casings, and mold bases for washing machines and air conditioners.
2. Large-Scale Material Inventory to Shorten Lead Times
Changhui maintains substantial inventories of forged materials such as P20 and S50C, while also supplying high-quality domestic and imported mold steels, including 2738, 718, NAK80, and H13. This ensures the ability to meet diverse customer requirements for material performance and cost. The company’s in-house raw material warehouse not only ensures quality control but also significantly shortens mold manufacturing lead times, helping customers respond more swiftly to market demands.
3. High-Precision Processing and Full-Process Quality Control
The company strictly adheres to the ISO9001 quality management system, implementing end-to-end quality control from material cutting, rough machining, precision milling, deep-hole drilling, and fine grinding to final inspection. The addition of imported coordinate measuring machines, horizontal machining centers, and high-precision mold base production lines ensures that every mold base meets design standards for dimensional accuracy, flatness, parallelism, and surface finish. For high-precision applications, tolerances can be controlled within ±0.01mm.
4. Professional Team and Continuous Innovation
Changhui employs over 100 experienced engineers and technicians, with more than 100 CNC operators and an R&D team of over 80 professionals. With an average monthly production capacity exceeding 15 million RMB, the company not only manufactures standard products but also undertakes custom processing of non-standard, large-size, high-precision mold bases, supporting both drawing-based and sample-based processing to flexibly meet customers’ unique requirements.
4. Key Industries Served and Customer Base
Changhui’s mold base products are widely used in:
- Automotive Industry: Large plastic and die-cast mold bases for bumpers, instrument panels, headlights, and fenders.
- Home Appliances and Consumer Electronics: Mold bases for LCD TVs, air conditioners, washing machines, cosmetic packaging, and stationery.
- Industrial and Communication Equipment: Structural components, enclosures, and more.
The company has established stable partnerships with renowned domestic and international enterprises such as Foxconn, BYD, Hisense, Haier, Huawei, YBSX, and Yihe Mould. Its products are not only supplied to the domestic market but are also exported to Southeast Asia, Europe, and the United States.
5. Quality Philosophy and Service Commitment
Changhui consistently adheres to the quality principle of "refining every process, pursuing卓越 quality." The company implements a three-step inspection process: incoming material inspection, in-process self-inspection, and final quality inspection, ensuring every step from raw materials to finished products is under strict control. Changhui has been certified under the ISO9001 International Quality Management System and has been recognized as a "Vice President Unit of the Guangdong Die & Mould Industry Association" and a "Contract-Honoring and Trustworthy Enterprise."
