Puji Street, Zhangqiu District, has the reputation of "the hometown of blacksmiths" and a thousand-year history of forging. In recent years, the street has expanded and extended the industrial chain, expanded and strengthened the high-end forging industrial clusters, and created a "intelligent manufacturing industry uplift belt". As of the end of 2021, there were 69 enterprises above the designated size in the jurisdiction, and the total industrial output value in August this year reached 312 million yuan, an increase of 18.6% year-on-year.

In Puji Street, Zhangqiu Heavy Forging Co., Ltd. is well-known to everyone. The company is a large enterprise group integrating forging, heat treatment, finishing, nitriding, carburizing, etc. The main products are core components in the fields of engineering machinery, wind power generation, , rail transit, etc., with an annual output value of 800 million yuan. In recent years, it has obtained 6 national invention patents and more than 20 utility model patents. Among them, the independently developed multi-functional CNC lathe and automatic energy-saving normalized furnace have been rated as Shandong Province's science and technology innovation promotion projects.

It is worth mentioning that in February this year, the company's 3200-ton crawler crane hook produced by the company for Zoomlion made the world's first steel containment lower cylinder successfully in place. The company adopts the world's most advanced Japanese Dawei vertical lathe , German Kapp, Niels grinding machine and Austria's Aixin nitriding and carburizing production line to achieve the world's advanced level of product accuracy, surface strength and service life. At the same time, the company has also been identified as one of the 420 key development enterprises in Chapter 1.

Baohua Heavy Industry, also located in Puji Street, is an extension unit of the industrial chain of Zhangqiu Baohua Forging Co., Ltd., whose main products are precision processing accessories such as engineering machinery, oilfield equipment, mining equipment, etc., targeting well-known domestic and foreign companies such as Bosch Rexroth, ZF, GE, Cameroon , Nangaochi, Yantai Jerry , Sany Heavy Industry , XCMG Group and other well-known domestic and foreign companies.

The total investment of 150 million yuan is underway for infrastructure construction tomorrow.

Puji Street takes the lead in establishing the Joint Party Committee of the Forging Machinery Industry Cluster in Chengqiu District East Forging Machinery Industry Cluster, establishing a Party Building Alliance for Forging and Finishing Industry, and building the organizational system on the industrial cluster. Give full play to the advantages of industry connection and similar regions, turn park management into community governance, and explore new models of "industrial communities". Build a "1+5+X" industrial cluster organizational system, "1" is the Joint Party Committee of the Forging Machinery Industry Cluster in the eastern part of Zhangqiu District; "5" is the Party General Branch of the Industrial Community; "X" is the enterprise party organization. Each industrial community has a grid, each grid is divided according to 4-10 enterprises, with one agency cadre and one core enterprise employee serving as part-time grid members, effectively transforming the party’s political and organizational advantages into enterprise growth advantages and industrial development advantages.
