2026-11-13

　　As the casting industry accelerates its shift toward intelligent manufacturing, 3D sand mold printing is breaking the physical constraints of traditional mold-making. However, purchasing a printer or a truckload of high-quality sand does not guarantee the consistent production of flawless molds. From raw sand selection and printing processes to pouring validation and used-sand recycling, any disconnect in these stages can significantly undermine the practical benefits of this cutting-edge technology.
　　Faced with these challenges, Lianxin Casting Sand Group’s response is clear: it will not merely be a supplier of 3D printing sand, but will instead become a pioneer in delivering end-to-end solutions for 3D sand mold printing. With the full-scale operation of the Shenyang 3D Sand Mold Printing Center, Lianxin officially announces: “ 3D sand mold printing has entered the era of comprehensive solutions. ”

　　 Strategic Pivot: From “Selling Sand” to “Technology-Driven Empowerment”
　　Lianxin doesn’t just sell 3D‑printed sand; it also helps customers truly “print” parts. The Shenyang 3D Sand Molding Printing Center serves as Lianxin’s strategic pivot, shifting its focus from materials to services and from product delivery to technology transfer.
　　What does choosing Lianxin mean for customers? In the market, suppliers that only sell toner often cannot solve your printing process issues; meanwhile, factories that only offer contract printing struggle to ensure optimal compatibility of consumables. Lianxin has bridged this gap. Materials R&D, Process Customization, Quality Inspection, and Used Sand Regeneration With our end-to-end approach, you receive not a single product or service, but a truly complete solution that requires no effort on your part.
　　 Cornerstone: Material self-sufficiency, defining sand specifically for 3D printing
　　Leveraging its proprietary sand-mining advantages, Lianxin has achieved independent R&D and large-scale production of sand specifically for 3D printing. Through meticulous particle-size control, the product perfectly meets the sand‑laying requirements of equipment from various domestic and international brands, while strictly limiting the content of 200-mesh and finer sand powder to below 5%, thereby addressing dust issues at the source. As a recipient of “The project’s overall technology has reached an internationally advanced level.” A highly regarded domestic premium product, Lianxin 3D Printing Sand offers the industry a high-performance, domestically produced alternative.

　　Core: Additive manufacturing, comprehensive technical consulting, and process customization.
　　Lianxin 3D Sand Molding Printing Center, backed by a strong technical team, provides customers with comprehensive, in-depth technical consulting across the entire process:
　　 1. Selection of aggregates and liquid materials: For different casting materials, we precisely recommend aggregate gradations and liquid (resin/hardener) systems to ensure mold strength and low gas evolution.
　　2. Parameter Design: Based on the complexity of the 3D model, parameters such as layer thickness and powder spreading speed are precisely set to balance efficiency and quality.
　　3. Customized Process: We offer customized printing and post-processing solutions for complex internal cavities, thin-walled parts, and various structural components, overcoming the limitations of conventional manufacturing processes.
　　 Guarantee: Inspection and support ensure sand molds stand up to the test.
　　Leveraging the Group’s robust R&D and testing capabilities, the Center ensures the quality of sand molds and castings. From tensile and flexural strength to gas evolution and permeability, product‑control standards that exceed industry norms are integrated into every stage. Through “pouring validation,” the high‑temperature performance of sand molds is tested in real conditions, enabling proactive mitigation of defect risks.

　　 Closed Loop: A Green Engine for Regenerative Recycling and Breaking Barriers
　　Recycling is an industry trend and a critical closed loop for comprehensive solutions. Lianxin has independently developed recycling equipment that outperforms industry standards, successfully overcoming technical barriers. Lianxin’s 3D printing sand regeneration system achieves a performance recovery rate of over 95% for used sand, with an overall used-sand recovery rate exceeding 85%. Waste sand molds undergo efficient regeneration, restoring their performance to meet specifications and returning them to the recycling loop. This not only significantly reduces customers’ overall sand‑use costs but also cuts solid waste emissions, helping companies cut costs, boost efficiency, and advance green casting.
　　From raw material extraction and sand production to aggregate and liquid selection, parameter optimization and print‑based shaping, finished‑product casting validation, and the efficient regeneration and recycling of used sand—Lianxin has woven these previously fragmented steps into a highly efficient closed loop. Powered by proprietary materials, precision processes, rigorous testing, and cutting‑edge regeneration technology, this loop is truly seamless. This is the essence of an “end‑to‑end solution”: not a piecemeal transaction, but full‑chain empowerment.
