In the consumer electronics manufacturing industry, mobile phone housing molds place extremely stringent demands on precision, strength, and stability. As the "skeleton" of molds, the quality of the mold base directly determines the forming precision, surface finish, and production efficiency of mobile phone housings. With 40 years of industry experience, Changhui Metal Products Co., Ltd. has become a trusted mold base supplier for mobile phone housing mold manufacturers, thanks to its high-precision manufacturing technology, advanced processing equipment, and comprehensive quality control throughout the entire process.

Mobile phone housing molds typically require high-precision standards of up to ±0.01mm. Changhui is equipped with over 50 advanced CNC machining centers, including large-scale machining centers with a maximum travel of 3500mm × 2500mm × 1500mm, capable of meeting the processing needs of large or highly complex mold bases. From material cutting, rough milling, and precision milling to deep-hole processing, the entire process adopts digitalized operations. Combined with precision inspection equipment such as coordinate measuring machines, the company ensures that the dimensional accuracy, flatness, and structural stability of mold bases meet the requirements of high-end molds.

Mobile phone housing molds often need to withstand high-frequency, high-pressure injection molding processes. Changhui uses high-quality mold steels such as P20, 718, and S136 and maintains a large inventory of forged materials to ensure the strength and thermal stability of mold bases from the source. Even under high-pressure and high-temperature conditions, the mold bases exhibit minimal deformation, effectively extending the overall service life of molds and meeting the demands of mass production for mobile phone housings.

Changhui strictly adheres to the ISO9001 quality management system and implements a triple quality control process: "incoming material inspection, in-process self-inspection, and final quality inspection." Each mold base undergoes data recording and electronic archiving during processing, ensuring full traceability from materials, processing, to delivery, and preventing defective products from being shipped. This provides a stable and reliable mold base foundation for mobile phone housing molds.

With a technical R&D team of over 80 members and more than 120 processing equipment units, Changhui flexibly provides customized services such as processing based on drawings or samples, supporting the manufacturing of non-standard large mold bases. With a monthly production capacity exceeding 1,500 sets, the company can quickly respond to customer demands, helping mobile phone housing mold manufacturers shorten delivery times and enhance market adaptability.

Changhui is ISO9001 certified and supplies mold bases to industry-leading companies such as Foxconn, BYD, Huawei, and Hisense. Its products are exported to Southeast Asia, Europe, and the United States. In the field of mobile phone housing molds, Changhui is recognized for its "high precision, stable strength, and fast delivery," consistently providing customers with cost-effective mold base solutions.

As a "hidden champion" in the mold base industry, Changhui leverages its technological expertise and manufacturing capabilities to provide a sturdy and precise foundation for mobile phone housing molds, empowering the consumer electronics industry to achieve high-quality and high-efficiency production.
