Recently, Taishan Xinrong Metal Products Co., LTD. (hereinafter referred to as "Taishan Xinrong") located in Taishan, Guangdong Province, has continuously gained market favor thanks to its key technological breakthroughs in the field of high-performance wheel hub mold casting. By integrating multiple independent patented technologies, the company has successfully optimized the casting process of large wheel hub molds (especially ductile iron and 42CrMo chromium-molybdenum alloy molds). While ensuring high dimensional accuracy and internal quality, it has stabilized the monthly comprehensive production capacity of such products at over 280 tons, providing reliable supply chain support for the downstream automotive and high-end equipment manufacturing industries.

Innovation-driven: Patent technology solidifies the foundation of quality

As a key process equipment for manufacturing automotive wheels, wheel hub molds have extremely strict requirements for heat fatigue resistance, strength and toughness, as well as dimensional stability. The traditional casting method is prone to problems such as shrinkage porosity, cracks and deformation, which affect the service life of the mold and the quality of the finished wheel hub.

We realized very early on that to establish an advantage in the niche market, we must have our own core technology. The technical director of Taishan Xinrong introduced. Since its establishment, the company has set a development path centered on technological upgrading and officially launched special research and development in 2019. By improving the alloy smelting process, optimizing the resin sand molding and regeneration system, and introducing precise heat treatment control technology, the company has effectively overcome the forming and defect control challenges of large and complex mold castings.

At present, Taishan Xinrong has cumulatively obtained 16 utility model patents, and these patented technologies have been systematically applied to the entire production process from smelting, molding to heat treatment. For instance, the customized resin sand regeneration treatment system it adopts not only enhances the stability of molding sand quality but also realizes green production. The precisely temperature-controlled heat treatment process ensures that the mold material acquires the ideal metallographic structure and mechanical properties. In 2022, the company was recognized as a National High-tech Enterprise, and its technological strength was officially acknowledged.

Intelligent manufacturing support: Advanced equipment ensures efficient delivery

Stable production capacity and quality cannot be achieved without advanced hardware support. Taishan Xinrong currently has one set each of 1500KG and 750KG medium-frequency induction furnaces, which can meet the flexible smelting requirements of different grades of alloys. The box-type heat treatment furnace and the 10-ton-per-hour resin sand regeneration treatment equipment form a stable quality guarantee at the back end. What is particularly crucial is that the workshop is equipped with 3T and 5T cranes, combined with a 1,500-square-meter standardized casting workshop, enabling it to efficiently complete the production organization and circulation of large mold castings weighing up to 2 tons each.

From 5 kilograms to 2 tons, our product range is wide. However, relying on mature process packages and meticulous production management, we can ensure consistency from samples to bulk orders. The production manager said. The company has established a complete quality monitoring system that runs through every process, adhering to the principle of "quality first".

Market recognition: Deep cooperation empowers the industrial chain

With solid technological accumulation and reliable product quality, Taishan Xinrong has established long-term and stable cooperative relationships with many well-known mold manufacturing enterprises. The wheel hub molds it produces not only serve the domestic market demand, but also attract the attention of international customers for their quality. The company's customized capabilities supported by technology can quickly respond to customers' special requirements for mold materials, structures and performance, which has become an important market competitiveness for it.

"Being recognized as a high-tech enterprise is not only an affirmation of our past efforts but also a spur for our future development." " The general manager of the company stated, "We will continue to improve our intellectual property management system, increase R&D investment in wear-resistant materials and precision casting, and aim to become a trusted partner in the global high-end mold casting field."

With the continuous growth of new energy vehicles and the demand for lightweighting, the demand for high-performance wheel hub molds will further increase. Taishan Xinrong Metal, with innovation as its blade and intelligent manufacturing as its foundation, is steadily moving towards the goal of "becoming stronger and larger", and is committed to contributing Chinese casting solutions to the global high-end manufacturing industry.
