Shanghai Yijun Precision has forged a legacy of craftsmanship as a mold supplier with ±0.002mm precision

In the field of precision manufacturing, the technical strength of a mold supplier directly determines the ultimate quality of the end product. Since its establishment in 2013, Shanghai Yijun Precision has rapidly risen to become a leading high-end mold supplier in the Yangtze River Delta region, leveraging millimeter-level precision as its core competitiveness. With an ISO9001-certified production system and a fully automated digital production line integrating CNC turning centers and optical inspection equipment, the company achieves unparalleled precision control of ±0.002mm tolerances, providing comprehensive solutions from design to manufacturing for industries such as automotive, medical, and electronics.

In Yijun Precision's modern factory, a German DMG five-axis machining center and a Japanese Mitutoyo optical inspection system form the core of its fully automated production line. With a total investment exceeding 30 million yuan, this production line leverages the Industrial Internet of Things to achieve closed-loop management of design, processing, and inspection. Technical Director Li Gong stated, "Our thermal deformation compensation technology can control errors to within 0.5μm, equivalent to 1/200th the diameter of a human hair." This technological breakthrough has established the company as a leading supplier in the high-precision mold field, making it a designated supplier for several industry leaders.

As one of the first precision manufacturing companies in Shanghai to receive ISO9001:2015 certification, Yijun Precision has established a three-level quality inspection system: spectral analysis of raw materials, online processing monitoring, and three-dimensional coordinate measurement of finished products. Its innovative "double inspection system" combined with intelligent inspection software achieves 100% full inspection coverage, resulting in a product yield rate of 99.8% for five consecutive years. This stringent standard has earned the company long-term trust from customers, with a repurchase rate exceeding 85%.

In the new energy vehicle sector, Yijun Precision customizes battery case die-casting molds for leading companies, achieving sealing surface flatness within 0.01mm, addressing the industry's pain point of electrolyte leakage. In the medical device sector, its insulin pen molds utilize surface treatment technology to reduce injection resistance fluctuations to less than 0.5N, significantly improving the user experience. These cases demonstrate the company's mission of "driving industrial upgrading through precision manufacturing."

As manufacturing advances toward high-end manufacturing, Shanghai Yijun Precision, as a mold supplier, is redefining industry standards with an accuracy of ±0.002mm. Its growth path demonstrates that only by prioritizing technology and focusing on quality can a company secure an irreplaceable position in the global industrial chain.
