From May 8th to 9th, the 21st China (Tianjin) International Foundry Expo was held. Shandong Huida Vermilion Equipment Co., Ltd., a subsidiary of Zhong'an United Investment Group, was awarded the "Gold Supplier" by Sino German Alliance. At the same time, the 7-meter coke oven protection plate produced by the enterprise won the Gold Award for High Quality Castings, and the exhibition won double gold medals in a row.

Chen Zhiyuan, member of the Standing Committee of Huantai County Party Committee, deputy county head, secretary of the Party Working Committee of Huantai Economic Development Zone, and relevant responsible comrades from Tangshan Town, Huantai County Bureau of Industry and Information Technology, and Shandong Huida Worm Ink Equipment Co., Ltd. attended the exhibition.

It is understood that the 7-meter coke oven protection plate displayed at the Casting Expo is one of the main accessories of coking equipment, mainly responsible for protecting the bricks of the coke oven body and changing with the temperature of the coke oven, thus protecting the normal production and operation of the coke oven equipment. Huida Vermilion uses the V-method casting process to produce coke oven protective iron parts. It is mainly based on the V-method casting process, where the sand does not contain adhesives. Plastic films are used to shape the sand mold. By vacuuming the sand box to harden the mold, the molding, sand drop, cleaning, and other processes are greatly simplified. Without the need for a sand mixer and adhesive supply equipment, the molding and sand treatment system can be simplified. Therefore, it has the advantages of high dimensional accuracy, clear contour, smooth surface, and small machining allowance in castings, and is highly favored by domestic and foreign customers.

The Foundry Expo was founded in 1987 and, after more than 30 years of development, has become one of the famous exhibitions in the global casting industry. It is the only casting exhibition organized by a national industry association in China, and has received active response and strong support from major casting enterprises and upstream and downstream industries. This year's tripartite exhibition covers a total area of 120000 square meters, attracting over 1300 well-known exhibitors from more than 30 countries and regions. With advantages such as high-end brands and first-class services, it attracts over 100000 professional visitors from more than 80 countries and regions around the world to negotiate online and offline procurement, becoming another annual event in the global casting industry. Relying on the exhibition platform, it effectively promotes the accelerated upgrading and leading development of Huida vermicular ink equipment.
