May 8, the 21st China International Foundry Expo in Tianjin - National Convention and Exhibition Center grand opening, attracting nearly 1,000 well-known enterprises from more than 30 countries and regions and tens of thousands of professional visitors to the event.

(hereinafter referred to as "SANDI"), a new generation of 3D printing equipment and rapid manufacturing service provider, comprehensively demonstrated 3D printing green rapid casting solutions such as 3DP/SLS sand rapid casting and SLS wax precision casting. (hereinafter referred to as "Longyuan Molding") won the "National Foundry Equipment Innovation Award" for its self-developed 3DP sand printing equipment AFS-J1600Pro.

AFS-J1600Pro equipment adopts international first-line high-precision, high-throughput nozzle, with high-performance molding process and intelligent algorithm technology, which can provide users with excellent molding accuracy, balanced and controllable casting performance and excellent reliability. The equipment is equipped with a new generation of high-speed vibration type powder spreading system, automatic feeding system and self-developed equipment control software, etc., sand size accuracy, high strength, low gas generation, excellent surface quality; equipment operation is simple, stable and reliable, with printing warning prompts, visual monitoring of the intelligent system can realize the whole process of processing of real-time monitoring and record traceability; open-source material process, can be adjusted for the user as needed; Matching high-performance resin binder, curing agent, cleaning agent, to ensure the molding quality and stability. The equipment can be widely used in aerospace and military, automotive, rail transportation, ship pumps and valves, construction machinery and other fields.

During the same period, the art sculpture "The Heroic Winds of the Han Dynasty" by Tongling Bronze Age Sculpture Co.

During the exhibition, SANDI Technology conducted an online live broadcast entitled "3DP Sand Printing Technology in Green Intelligent Casting Application Practice" through NJB Live Platform, which was jointly presented by Dr. Zhao Hao, Vice President of Product Technology of SANDI Technology, and Mr. Tan Dawei, General Manager of Xinxin Foundry, and attracted thousands of viewers to pay attention to the interaction.

In 2023, the Ministry of Industry and Information Technology, the National Development and Reform Commission, the Ministry of Ecology and Environment jointly issued the "Guidance on Promoting the High-Quality Development of the Foundry and Forging Industry" (Ministry of Industry and Information Technology Joint Communication and Installation 〔2023〕 No. 40), it is clearly pointed out that, by 2025, the focus of the field of high-end castings, forgings, breakthroughs in the core technology, mastering a number of core technologies with independent intellectual property rights, integrated die-casting molding, moldless casting, sand molding 3D printing, ultra-high-strength steel hot forming, precision cold temperature hot forging, lightweight high-strength alloys lightweight and other advanced process technologies to achieve industrialization and application, in the key tasks put forward to "develop advanced casting technology and equipment", focusing on the development of "short process casting, sand 3D printing and other advanced casting technology and equipment. ."

Dr. Zhao Hao analyzed and interpreted the role and business opportunities of 3DP sand printing technology in green rapid casting in his report, and shared the molding process, intelligent algorithm technology, and sand process solutions of the company's self-developed 3DP inkjet sand printing equipment.

He said that 3DP sand printing technology in green intelligent casting can be mainly used for complex, high-end product manufacturing, such as aerospace, military and other fields, improve product structure design, improve product performance; rapid R & D trial production, such as new energy automotive parts and components of the R & D trial production, to reduce the mold investment and waste, and improve the production environment; small batch multi-species manufacturing, such as ships, pumps and valves, equipment and instruments and other fields, data Data-driven, rapid flexibility, accelerate new product development. By joining hands with Xinxin Casting, SANDI can provide users with one-stop, full-process rapid casting delivery solutions.

Tan Dawei, General Manager of Xinxin Casting, further shared the process flow of 3DP sand green fast casting through several typical application cases of 3DP sand printing in actual casting production, and analyzed the positive impacts brought by 3DP technology in terms of delivery cycle, cost of small batch production, mold accuracy and economic benefits.

Through the deep cooperation with SANDI Technology, Xinxin Foundry became the first foundry in Shaanxi Province to introduce the advanced technology of 3DP sand printing fast casting, and successfully transformed into a green fast casting demonstration factory.

The exhibition will last until May 11th, China National Convention and Exhibition Center (Tianjin), SANDI Technology booth: Hall S13 - Booth D07, welcome to visit and communicate with us!
