"Light of Chinese Goods" Lianxin 3D Printing Special Sand Appears at 21st Casting Fair

Release time:


A few days ago, the "Lianxin 3D Printing Special Sand" with the reputation of "Light of Chinese Goods" was unveiled at the "21st China International Foundry Expo" in Tianjin ".

"Lianxin 3D Printing Special Sand" attracted a large number of industry experts and many well-known 3D printing equipment enterprises to visit and exchange at the Expo site because of its high-end quality market positioning and better cost-effective market reputation.

On May 9, 2023, guests gathered at the booth of Lianxin Casting Sand Group in Hall S14 of Tianjin National Convention and Exhibition Center. The guests attending the "Special Promotion Meeting of Lianxin 3D Printing Special Sand" included Gao Wei, Executive Vice President of China Foundry Association, Zhao Zhili, Expert Committee Member of China Foundry Association, Zhang Bo, Vice President of Liaoning Foundry Association, Liu Yue, Professor of Northeastern University, Yu Ruilong, Deputy Director of Shenyang Foundry Research Institute, etc. At the same time, well-known equipment manufacturers in 3D printing industry: luoyang Yipute Intelligent Technology Co., Ltd., Wuxi Huisite Rapid Manufacturing Technology Co., Ltd., Guangdong Fenghua Zhuoli Technology Co., Ltd., Ningxia Shared Equipment Co., Ltd., Crystal Porcelain (Beijing) New Material Technology Co., Ltd., Shaanxi Zhongchuang Special Jingzeng Technology Co., Ltd. and other companies also participated in the promotion meeting; Deng Yuhui, Chairman of Lianxin Casting Sand Group, and Li Jiabo, Deputy General Manager; intercontinental Media, Beijing Future Foundry Magazine and other foundry industry media also participated in this promotion.

Gao Wei, executive vice president of China Foundry Association, delivered a speech at the scene. President Gao mentioned that "compared with imported sand, the strength of the 3D printing special sand series products developed by Lianxin Foundry Sand Group can be increased by 30% under the same resin addition amount, which means that the same strength as imported sand can be obtained with a lower resin addition amount, and the price is less than 50% of the price of imported sand. This product has applied for a national patent, the evaluation of the results of the 3D printing special sand by the China Foundry Association is also in progress, and it is expected that Lianxin Casting Sand Group will continue to introduce more casting products with international market competitiveness.

At the same time, I hope that with the development of China's foundry industry, more companies like Lianxin Casting Sand Group will emerge, willing to invest in research and development, and through technological breakthroughs, help foundry companies achieve high efficiency, energy saving, green, and environmental protection, and truly achieve Sustainable development. Through the continuous upgrading of foundry upstream enterprises, the core competitiveness of Chinese foundry products in the international foundry market will be enhanced."

Since the launch of 3D printing special sand in 2021, Lianxin Casting Sand Group has continuously upgraded its products according to market demand. At present, there are four series of products that can meet the production needs of different 3D printing manufacturers.

  In particular, the -3 series of products launched in September 2022 have broken through a series of problems such as the difficulty of domestic 3D printing sand, large consumption of liquid materials, poor stability and low cost performance.

  The reason why "Lianxin 3D printing special sand" can win the reputation of "the light of domestic goods" is inseparable from the continuous investment in research and development. The continuous upgrading of technology, coupled with the unique high-quality raw sand as the foundation, makes the "Lianxin 3D printing special sand" continuously upgrade in quality, which also represents domestic high-end 3D printing sand, and continuously widens the gap with overseas 3D printing sand.

"United Letter3DPrinting special sand "advantage is very obvious, as follows:

1. surface pretreatment technology: remove harmful impurities on the surface of silica sand and use slurry to repair surface defects of silica sand, so that a strong chemical bond is formed between resin and silica sand to improve the utilization rate of liquid material and enhance the strength of sand mold.

The 2. uses natural wind-deposited sand as the main raw material, the material source is stable, the grain type is round, and the sand with low Senior high school and different grades of silicon content can be produced by blending, which can adapt to casting defects (such as veins, etc.) caused by unsuitable silicon content in castings of different materials.

The 3. adopts a self-developed 3D sand special production line, which is controlled by a fully automated production process to avoid manual influence on product stability. At the same time, the professional screening and distribution line can ensure accurate and stable product particle size control and extremely low dust content.

The 4. is cost-effective, and its current performance is comparable to that of imported sand. The price of Lianxin 3D printing sand products is less than 1/2 of that of imported sand.

At the beginning of research and development, "Lianxin 3D printing special sand" is committed to making more domestic foundry enterprises not only afford 3D printing equipment, but also afford 3D printing sand, and it is a high-end 3D printing sand that can be superior to overseas imports in performance. With the upgrading and development of China's foundry industry, it is hoped that there will be more "light of domestic products" such as "Lianxin 3D printing special sand", which can provide more foundry enterprises with better quality and more cost-effective products and services for the overseas foundry market and the high-end casting market.
