Shandong Jinfeng Trading Co., Ltd.

Shandong Jinfeng Trading Co., Ltd. is located in Licheng District, Jinan. With fifteen years of dedicated experience in the engineering machinery parts sector, it is a modern, integrated industrial‑trade enterprise. Over the past fifteen years, we have consistently focused on the R&D and manufacturing of filtration consumables and the comprehensive supply of all categories of engineering components. Leveraging our robust end-to-end capabilities across research, production, and sales, we have established a strong presence in both domestic and international markets, seamlessly integrating independent manufacturing, inventory management, channel distribution, and import‑export trade into a complete, vertically integrated value chain.

The company operates its own production facilities and quality‑control laboratories. Its proprietary brand, Manzhichen, centers on self‑developed filter elements and specializes in manufacturing air filters, oil filters, diesel fuel filters, and hydraulic oil filters tailored for excavators, loaders, and heavy‑duty trucks. From material selection and molding to final product inspection, the entire process is rigorously managed in‑house, with custom modifications available upon request. The products are compatible with mainstream construction equipment from SANY, XCMG, Volvo, Komatsu, Hitachi, Kobelco, Caterpillar, Isuzu, and other leading manufacturers, delivering OEM‑level filtration performance at an exceptional price‑performance ratio. In addition to its dedicated filter‑element production line, the company leverages fifteen years of supply‑chain expertise to consolidate a full range of engineering consumables—including hydraulic components, seals, drive belts, and rubber‑plastic parts—enabling one‑stop procurement and supply of all necessary spare parts.

Leveraging an integrated industrial‑trade model, we maintain full control over production, rigorously ensure quality, flexibly schedule output, and minimize intermediate costs. We also boast a dedicated team for sales, product selection, and international trade, along with a large in‑house warehouse stocked with ready‑to‑ship inventory. By capitalizing on Shandong’s strategic logistics hub, we deliver orders nationwide with exceptional speed. Furthermore, holding our own import‑export qualifications, we export Manzhichen filters and the entire range of accessories to infrastructure markets across multiple countries. For fifteen years, we have steadfastly upheld the highest standards of quality, refining our products through unwavering focus and serving our customers with professional expertise, partnering with thousands of construction fleets, repair shops, and distributors nationwide.

Going forward, the company will continue to deepen its efforts to upgrade the Manzhichen brand, expand its production lines, and refine its filtration technologies. Leveraging its core advantage of integrated manufacturing and trade, it will build a more robust supply-chain platform for construction machinery parts, working hand in hand with partners across regions to achieve shared, long-term success.
