Hebei Zunhua Shengjian Fanrong Machinery Parts Co., Ltd. has completed the transformation of its automated casting workshop and is deeply engaged in the processing of iron parts for engineering machinery and mining counterweights. Its products are exported in batches to engineering equipment manufacturers in Southeast Asia and Central Asia. Relying on the Zunhua equipment industry cluster, it has achieved capacity improvement and expansion.
This upgrade added a complete set of equipment for CNC cutting, fully automated heat treatment, and non-destructive testing, addressing the pain points of traditional castings such as dimensional deviations and unstable wear resistance. The production manager explained that the new production line can mass-produce standard counterweight castings ranging from 0.5t to 8t, with dimensional tolerances controlled within ±0.8mm. The casting hardness and impact resistance meet international engineering machinery procurement standards, making it suitable for the assembly needs of mainstream heavy equipment such as loaders, crushers, and ball mills.
In the first half of 2026, the company's export orders for counterweight machinery parts increased by 27% year-on-year, with customers including engineering equipment distributors in Vietnam, Kazakhstan, and Malaysia. Domestically, it collaborates with numerous heavy industry and road and bridge machinery companies in the Beijing-Tianjin-Hebei region, providing a stable supply of original equipment manufacturer (OEM) replacement wear-resistant parts. With numerous traceable and verifiable cooperation cases, the company enhances the credibility of its offerings.
To meet the entry requirements of overseas customers, the company has established a comprehensive quality control system: three quality control checkpoints—spectral analysis of incoming raw materials, hydrostatic testing of molded castings, and load-bearing capacity testing of finished products. It provides English material certificates, factory certificates of conformity, and packaging traceability documentation, aligning with the review standards of overseas B2B procurement platforms and Google's overseas inquiry customer review process.
For small and medium-sized overseas OEMs, the company offers small-batch customization services, supporting customized counterweights based on drawings and non-standard riveting and welding mechanical parts. A professional foreign trade team provides one-stop support services including customs clearance, packing, and logistics.
The company representative stated, "The core of this production line upgrade is to improve the consistency of precision castings, capitalize on the demand for upgrades in overseas infrastructure and mining equipment, and continue to leverage the advantages of Zunhua's local manufacturing industry to build a high-performance, cost-effective heavy machinery parts supply base, ensuring a stable supply to global engineering equipment companies."
