Recently, Taishan Xinrong Metal Products Co., LTD., which focuses on the high-end casting field, announced that it has made a major technological breakthrough in the research and development and manufacturing of ductile iron wheel hub molds. This progress is expected to significantly enhance the durability and production efficiency of wheel hub molds.

Technological innovation drives industry upgrading

Ductile iron has become a key material for the manufacturing of automotive wheel hub molds due to its excellent mechanical properties, good casting processability and high cost performance. However, traditional ductile iron molds are prone to problems such as thermal fatigue cracks and decreased dimensional accuracy when exposed to high-temperature and high-pressure casting environments for a long time, which affects the service life of the molds and the quality of the products.

Taishan Xinrong Metal Products Co., LTD., relying on its years of technological accumulation in the casting field, has successfully developed a new generation of ductile iron wheel hub mold manufacturing technology. The company's technical director stated: "By optimizing the chemical composition of ductile iron, improving heat treatment processes and adopting advanced surface treatment technologies, we have enhanced the thermal fatigue resistance of the molds by over 30% and extended their service life by 40%."

Dual breakthroughs in technology and craftsmanship

It is understood that the innovative technology route adopted by the company mainly includes three aspects:

Breakthroughs in materials science: By precisely controlling the content of magnesium, rare earths and other elements in ductile iron, improving the morphology and distribution of graphite, and enhancing the strength and toughness of the material.

Process innovation: By integrating computer simulation technology, optimize mold design and reduce stress concentration; Special heat treatment processes are adopted to enhance the heat resistance and wear resistance of the mold.

Surface treatment technology: By applying advanced surface strengthening technology, a high-temperature resistant and wear-resistant protective layer is formed on the working surface of the mold, further enhancing the performance of the mold.

Equipment upgrades ensure high-quality production

To support this technological breakthrough, Taishan Xinrong Metal has completed the upgrading and transformation of its production line this year, adding a set of precision machining centers and a five-axis CNC machine tool to ensure that the processing accuracy of the molds reaches the micron level.

"Our current production equipment is fully capable of meeting the manufacturing requirements of high-end wheel hub molds," the company's production manager introduced. "From casting to heat treatment and then to precision processing, we have achieved full-process quality control."

Intellectual property protection promotes continuous innovation

As a national high-tech enterprise recognized in 2022, Taishan Xinrong Metal attaches great importance to the protection of intellectual property rights. Up to now, the company has obtained 16 valid utility model patents, many of which are directly applied to the manufacturing of ductile iron wheel hub molds.

"We regard innovation as the lifeline of our enterprise development," said the company's general manager. "By establishing a complete intellectual property management system, we not only protect our core technologies but also provide institutional guarantees for continuous innovation."

The market response has been positive and the industry prospects are broad

With the rapid development of the new energy vehicle industry and the advancement of the trend towards automotive lightweighting, the demand for high-performance wheels continues to grow, putting forward higher requirements for the quality and performance of wheel hub molds.

The new generation of ductile iron wheel hub molds of Taishan Xinrong Metal has been successfully applied in many well-known wheel hub manufacturing enterprises. User feedback shows that the new molds not only improve the production efficiency of wheels but also significantly reduce the defect rate.

"Compared with traditional molds, after using the ductile iron molds of Xinrong Metal, our production efficiency has increased by about 15%, and the product consistency has also been significantly improved," said a representative of a cooperative enterprise. "This helps us maintain an advantage in the fierce market competition."

Industry impact and Future outlook

Industry experts believe that Taishan Xinrong Metal's technological breakthrough in ductile iron wheel hub molds not only enhances the company's own market competitiveness but also provides strong support for the technological progress of the entire wheel hub manufacturing industry.

"Molds are the mother of industry, and high-quality molds are the foundation for the high-quality development of manufacturing," an industry analyst pointed out. "This technological innovation will help promote China's transformation from a major wheel hub manufacturing country to a powerful one."

Looking ahead, Taishan Xinrong Metal stated that it will continue to increase investment in research and development, further optimize the performance of ductile iron wheel hub molds, and at the same time explore the application of related technologies in the manufacturing of high-end molds in other fields.

"We plan to increase the proportion of R&D investment to over 8% of annual sales revenue within the next three years," the company's technical director disclosed. "We are exploring the application of artificial intelligence technology in the mold design and manufacturing process to achieve a higher level of intelligence and automation."

With the continuous growth of global manufacturing demand for high-quality molds, Chinese foundry enterprises represented by Taishan Xinrong Metal are demonstrating increasingly strong international competitiveness in the high-end mold manufacturing field through continuous technological innovation, contributing to the high-quality development of China's manufacturing industry.
