In the foundry industry, every cost is related to competitiveness, and every innovation determines the market pattern. In the face of the dual challenges of casting yield and cost control, Lianxin Casting Sand Group has successfully developed the world's leading 3D printing sand regeneration ecosystem with hard-core technology, and the performance recovery rate of old sand has exceeded 95%, opening a new chapter of green and efficient for the industry!

Why do foundry companies urgently need sand recycling technology?

Traditional 3D printing sand consumes a lot of money and has high costs, and the disposal of waste sand has become an environmental protection problem. Lianxin Casting Sand Group has been deeply engaged in the pain points of the industry, and has developed and launched a 3D printing sand regeneration ecosystem for several years, which achieves a performance recovery rate of more than 95% through multi-stage purification, particle size control and performance reconstruction of old sand, which is almost "non-destructive regeneration". This means that the comprehensive cost of sand materials of the enterprise has dropped by more than 30%, the pressure of environmental protection has been sharply reduced, but the quality of castings is as stable as a rock!

From domestic substitution to technology leadership, the rise of Unicredit 3D printing sand

As an earlier enterprise in China to conquer high-end 3D printing sand technology, since its launch in 2021, Unicredit 3D printing sand has quickly replaced overseas imported sand with an annual sales volume of more than 20,000 tons (as of early 2025) with the advantages of comparable to the quality and price of international high-end 3D printing sand by 40%, serving more than 100 foundry enterprises across the country. Unicredit 3D printing sand products are the first 3D printing sand products recognized by the China Foundry Association as "the overall technology of the project has reached the international advanced level". Behind the certification of "international advanced level" by China Casting Association is Lianxin Casting Sand Group's dedication to technology iteration: from sand uniformity to high temperature stability, every grain of sand is defining industry standards.

Unitrust 3D printing sand regeneration ecosystem: not only to reduce costs, but also to revolutionize the sustainable development of the foundry industry

The core value of Unitrust Recycling System is to build a closed loop of "resource-production-regeneration" for foundry enterprises:

✅ Sand consumption reduced by 40% and casting yield increased by 30%

✅ The comprehensive recovery rate of old sand exceeded 85%

✅ 50% reduction in carbon footprint of the whole process

Lianxin Casting Sand Group: Empowering China's intelligent manufacturing with technological dividends

From "comprehensive substitution of domestic high-end sand for imports" to "successful R&D of the global 3D printing sand regeneration ecosystem", Lianxin Casting Sand Group has always been at the forefront of technological breakthroughs. Lianxin Casting Sand Group firmly believes that only by making 3D printing sand affordable and good for every enterprise can we truly promote the foundry industry to move towards intelligence and green. In the future, Unicredit 3D printing sand will continue to rely on the market foundation of 20,000 tons of annual sales, and work with industry partners to build an efficient, low-carbon and sustainable casting ecology!

Authoritative certification of China Foundry Association - 3D printing sand technology consulting area

The 3D printing sand technology consultation area, officially authorized by the China Foundry Association, was officially unveiled at the 23rd China International Foundry Expo at the National Convention and Exhibition Center in Tianjin (Booth B02 in Hall S2) from May 20 to 23, 2025. The zone is led and operated by Lianxin Casting Sand Group, based on its self-developed benchmark products in the 3D printing sand industry and mature market operation mechanism, which has attracted foundry industry enterprises and people from all over the world as soon as it was unveiled.
