The completion and commissioning of Lianxin Foundry Sand Group’s Chongqing Production Base means foundry enterprises in central and western China can obtain a full range of more professional and premium foundry sand products without long-distance procurement. Supported by the Group’s abundant technical reserves and sound supply chain system, the Chongqing Base can rapidly address the personalized demands of nearby manufacturers, drastically cut logistics and time costs, and help foundry enterprises improve production efficiency and maintain consistent product quality.

Backed by Solid Strength: Million-Ton Sales, 600-Million-Yuan Scale, Trusted by 2,000 Partners

By early 2026, Lianxin Foundry Sand Group has achieved remarkable operational results: its annual sales volume of all types of foundry sands exceeded 1.1 million tons, annual sales revenue topped 680 million yuan, and it has provided services to over 2,000 foundry enterprises. More notably, the Group boasts the highest repeat purchase rate for foundry sand products nationwide. These impressive figures stem from consistent customer recognition of the Group’s superior product quality and professional service capabilities. The high repeat purchase rate demonstrates that the Group’s foundry sands, in terms of stability and uniformity, alongside the effectiveness of its customized solutions, have withstood long-term and stringent market scrutiny.

Full Replication of Proven Successful Cases: Empowering Chongqing Base to Stand on the Shoulders of Giants

Lianxin Foundry Sand Group has accumulated abundant successful cases in the R&D of sand products and customized solution services. From optimizing sand formulas to eliminate specific casting defects to the overall design of sand systems for various casting processes, the Group has delivered targeted technical support to thousands of foundry manufacturers.

Now, all these field-proven successful experiences will be fully replicated at the Chongqing Production Base, enabling local foundry companies to rapidly access mature and reliable products and processes. Whether for auto parts, hydraulic components or 3D printed castings, the Chongqing Base can draw on the Group’s case library to deliver ready-to-use or quickly adaptable solutions.

Inspection & Early Warning: Prevent Casting Defects at the Source

Casting defects usually stem from performance fluctuations of sand products. To address this issue, Lianxin Foundry Sand Group has independently developed a full range of testing and analysis equipment for foundry sands, and fully rolled out this capability at its Chongqing Production Base.

The Chongqing Base can conduct rapid and precise testing on every batch of sand products for key indicators including particle size distribution, clay content, acid demand value and loss on ignition. More importantly, this testing system is not only applied to factory outgoing inspection, but also capable of early warning against potential defect risks arising during customers’ production processes. It helps foundry enterprises adjust process parameters before problems emerge, drastically cutting reject rates and rework costs.

Genetic Advantage of Zhangwu Aeolian Sand: Lock Quality at the Source

All sand products adopted by the Chongqing Production Base are sourced from the Group’s headquarters in Zhangwu, Liaoning. Famous for its naturally rounded grain shape, uniform particle size and high silicon dioxide content, Zhangwu aeolian sand is hailed as the "gold raw material" among all foundry sands. This inherent natural superiority lays a solid foundation for all sand products manufactured at the Chongqing Base. Coupled with Lianxin Foundry Sand Group’s technological strengths in sand product R&D, process optimization and customized formulations, the high-quality foundry sands supplied to central and western foundry enterprises integrate both natural merits and technological empowerment.

The grand opening of Lianxin Foundry Sand Group’s Chongqing Production Base marks not only a key milestone in the Group’s national strategic layout, but also tangible benefits for foundry manufacturers across central and western China. From this local base, foundry enterprises will enjoy shorter delivery cycles, professional technical support, consistent product quality and a more competitive cost structure. Going forward, adhering to its mission of "Empowering casting quality through technological R&D, from molding sand to finished castings", Lianxin Foundry Sand Group will stand side by side with foundry partners in central and western China to jointly forge a new future of high-performance castings.
