Kejia (Changxing) Mould Base Manufacturing Co., Ltd. (Kejia Mould Base) is a company specializing in the production of die casting mould bases and the sales of mould steel. Established in 1984, the company now employs over 420 people and owns more than 200 CNC machining centers and various processing equipment. Kejia Mould Base has integrated the upstream and downstream production chain, connecting forging, heat treatment, rough machining, and precision machining. It has become a leading large-scale mould base manufacturer in China.

Die casting mould development requires mould base support, as the structure and manufacturing precision of the mould base directly impact the mould’s structure and the precision of forgings. The quality innovation journey between Kejia Mould Base and Haitian Precision began in 2008, with the purchase of the first HTM-1000G, which is still in operation today for rough machining of steel parts.

Su Jian, the General Manager of Kejia Mould Base, has deep insights into Haitian Precision’s machines. Over the 16 years of cooperation, Haitian Precision has gained his trust with its strong technical advantages, reliable product quality, and efficient processing capabilities. A stable and reliable partner like Haitian Precision has enabled steady business growth. Currently, 20 Haitian Precision machines are hard at work in Kejia’s new Changxing facility, contributing to Kejia’s growing sales performance.

Amid the wave of large-scale die casting, Kejia Mould Base keenly anticipated market trends and was the first to collaborate with a renowned international automotive brand to co-develop the world’s first aluminum alloy die-cast chassis rear axle mould base. This innovation marked a historic breakthrough, reducing the number of components from over 300 parts needing stamping and welding to just three for assembly. Non-standard mould bases have higher commercial value, and this breakthrough also tested the precision and rigidity of Haitian Precision’s equipment.

Haitian Precision’s gantry-type five-face milling center excels in high-speed, high-precision machining of complex surfaces, making it ideal for moulds with large surfaces, multi-angle deep cavities, and automotive body panels. At Kejia Mould Base, Haitian Precision’s equipment is used to manufacture mould bases for new energy vehicle front and rear axles, battery boxes, and other components. The side milling head allows for the processing of five surfaces in one setup, and angled cuts can be completed with a single clamping, achieving excellent precision and high surface smoothness. Additionally, after implementing Haitian Precision’s equipment, processing times have been significantly shortened, delivering impressive efficiency.

“Haitian Precision’s gantry machines are highly rigidincreasing processing efficiency by 30-40% whenworking with materials with a hardness of HRC50-60. “

Kejia Mould Base’s Changxing facility now has the capacity to produce over 3,000 sets of mould bases annually, including over 300 sets of lightweight integrated structural mould bases for new energy vehicles. With rapid business growth, Kejia Mould Base has increased its investment in digitization by introducing ERP, MES, and OA systems to ensure a complete product supply chain, shorten production cycles, and ensure fast delivery. The company is optimizing its smart manufacturing capabilities and deepening cooperation with Haitian Precision to guarantee efficient and stable processing. Currently, Kejia Mould Base has established long-term partnerships with well-known brands such as XPeng and NIO, and plans to further expand into North American and European markets to enhance the global competitiveness and market share of its large-scale mould bases and integrated die-cast mould bases.

In the mould base industry, Kejia Mould Base has won customers over with its technology and quality. We firmly believe that innovation is the driving force behind industrial progress. Whether in traditional industries or new sectors, Haitian Precision continues to innovate and explore the realm of smart manufacturing, playing a key role in every transformation and upgrade in the manufacturing industry.
