In the realm of precision manufacturing for the automotive industry, the quality of molds directly determines the performance, appearance, and reliability of the final product. The mold base, serving as the "skeleton" and "foundation" of the mold, is paramount for its accuracy, strength, and stability. Changhui, a leading enterprise in China's mold industry, specializes in providing customized solutions for high-precision, high-performance automotive injection mold bases.

Changhui has consistently ranked at the forefront of the mold base industry for years, achieving sustained and rapid growth in scale through robust technological expertise and exceptional product quality. The company is not only ISO9001 certified, ensuring standardized and traceable processes, but has also been recognized as a Vice President Unit of the Guangdong Die & Mould Industry Association and a multi-year honoree of the "Contract-Honoring and Trustworthy Enterprise" title. We are a strategic partner to numerous renowned companies in the sector, with a solid reputation for reliability and capability.

We deeply understand the stringent requirements for precision and reliability in automotive parts. Changhui possesses strong capabilities in customizing non-standard and large mold bases, perfectly meeting the needs for molds producing large, complex injection-molded parts such as automotive bumpers, instrument panels, and fenders. Our technology is also widely applied in mold manufacturing for large home appliances like LCD TV panels, washing machines, and air conditioners. Whether your needs are for standard specifications or special customization, we offer a one-stop service from design support to finished product delivery.

The company operates over 60 production units, including 35 advanced CNC machining centers. Our large-scale machining centers boast a maximum working travel of X-axis 3500mm, Y-axis 2500mm, and Z-axis 1500mm, equipped with deep-hole drilling capable of machining water lines up to 1450mm deep. This ensures the integrated manufacturing capability for large, deep-cavity mold bases and efficient cooling channel processing.

Our pursuit of quality begins with raw materials. All custom mold steel is naturally aged for 90 days to thoroughly relieve internal stresses, then subjected to rigorous screening including spectroscopic analysis and flaw detection before being put into production. This guarantees the mold base's high hardness, superior surface finish, strong corrosion resistance, and long-term dimensional stability from the source.

Changhui is supported by a professional engineering R&D team of over 30 experts, working closely with more than 60 experienced CNC technicians. Our mature process planning workflow allows for rapid feasibility assessment based on customer-provided drawings and specifications, optimizing tool paths, cutter selection, and parameters to ensure top-tier quality while maximizing efficiency. The company currently maintains substantial monthly production capacity, enabling flexible response to orders of varying volumes with guaranteed on-time delivery.

Our products serve not only the domestic market but are also exported to Southeast Asia, Europe, and North America. Our cooperation process is clear and efficient:

Choosing Changhui means choosing a reliable partner for high-precision mold bases. We are committed to being the strongest link in your automotive injection mold supply chain through outstanding engineering, advanced manufacturing capabilities, and an unwavering commitment to quality.
