　　In early 2025, exciting news came from China's casting industry—Lianxin Casting Sand Group's "Lianxin 3D Printing Sand" exceeded 20,000 tons in annual sales, serving over 200 3D printing equipment units nationwide, and redefining the new standards of the casting industry with domestic strength. Behind this achievement is the consistent commitment of Lianxin people: to enable every Chinese casting enterprise to use 3D printing sand comparable to international quality.

　　 I. The Disruptor: From Technological Breakthrough to Standard Setting

　　When international brands had long monopolized the high-end 3D printing sand market, Lianxin Casting Sand Group embarked on an independent research and development path with the belief that

　　strong materials make strong castings. Facing industry skepticism that "Northern sand is not suitable for 3D printing," the Lianxin R&D team, in collaboration with the Shenyang Foundry Research Institute, overcame material constraints after years of technological research and development—not only achieving international advanced levels for domestic sand, but also participating as a core unit in the formulation of the industry standard for "Casting 3D Printing Silica Sand."

　　With the R&D philosophy of "practice is the sole criterion for testing truth," Lianxin 3D printing sand achieved a double breakthrough: becoming a synonym for high-end domestic 3D printing sand and creating a high-quality domestic product that can completely replace imported products. Authoritative verification shows that the overall project technology has reached internationally advanced levels, marking a crucial leap from follower to leader in China's 3D printing sand mold material field.

　　 II. Core Strength: Full-Scenario Adaptability for the Future of Casting

　　The market is the fairest judge. By the first half of 2025, Lianxin 3D printing sand has been successfully applied to various models of 3D printing equipment at home and abroad, demonstrating excellent compatibility: adaptable to 200+ 3D printing equipment units of different brands; perfectly matching the world's mainstream printing liquid material systems (resin, curing agent); and serving multiple fields including automotive, aerospace, and precision instruments.

　　Behind this "full-scenario adaptability" is Lianxin Casting Sand Group's deep understanding of the pain points in the casting industry. A technical director from a heavy machinery company commented: "After using Lianxin 3D printing sand, our equipment uptime has significantly improved, and we no longer need to stop for debugging due to material compatibility issues."

　　 III. Green Revolution: Regeneration Technology Reshapes Industry Costs

　　Under the guidance of the "dual carbon" strategy, Lianxin Casting Sand Group's independently developed 3D printing sand regeneration ecosystem is driving industry transformation. Through a unique regeneration process, it achieves: a restoration rate of used sand properties exceeding 95%—approaching "infinite cycle" use; a reduction in enterprise comprehensive sand costs by over 30%; and a 40% reduction in sand consumption while increasing casting yield by 30%.

　　More noteworthy is its environmental value: a 50% reduction in the overall carbon footprint and an 85% comprehensive recovery rate of used sand. This "economic + environmental" dual-advantage solution will enable casting enterprises to achieve tangible cost reduction and efficiency improvement, reconstructing the cost logic.

　　From the milestone of 20,000 tons of annual sales to the large-scale application serving over 200 equipment units, Lianxin Casting Sand Group's "Lianxin 3D Printing Sand" is writing a "materials revolution" in China's casting industry. In the future, with the implementation of the industry standard for "Casting 3D Printing Silica Sand," this domestic sand force will continue to unleash innovative potential, providing stronger "China sand" support for the era of intelligent manufacturing.
