Import 200 Ductile Castings — Buy in wholesale FOB from Supplier in China

Vlwin Machinery Industry Co., Limited, based in Zhenjiang City, China, supplies ductile iron castings (also known as nodular cast iron or SG iron) engineered for demanding industrial use. These castings are available in unit weights from 2 kg to 500 kg and are manufactured to meet international standards such as ASTM A536 and EN 1563, which specify minimum tensile strength, yield strength, and elongation for various ductile iron grades. The material's graphite nodules give it significantly higher impact resistance and fatigue strength compared to conventional grey iron, making it suitable for parts that experience dynamic or shock loading.

Ductile iron grades commonly used for industrial castings include ASTM A536 Grade 65-45-12 (65 ksi tensile, 45 ksi yield, 12% elongation) and EN 1563 EN-GJS-400-18, both offering a balance of strength and ductility. Typical applications span pump and valve bodies, gearbox housings, brake calipers, hydraulic manifolds, pipe fittings, and heavy machinery structural components. Castings are produced via green sand or resin sand moulding, with tolerances generally held to ISO 8062 CT8-CT10 depending on geometry and size. Surface roughness after shot blasting typically falls in the Ra 12.5-25 µm range for as-cast parts.

Buyers in the automotive, oil and gas, water infrastructure, and general engineering sectors source these castings for OEM assembly lines and MRO supply chains. The listing states that reinforced wooden crates are used for export packing, which is standard for heavy iron castings shipped by sea. Vlwin Machinery Industry Co., Limited is listed on the platform as a harbour-tier supplier, and the listing does not provide a current response rate or average response time, so buyers should confirm MOQ, lead time, and any certifications (such as ISO 9001 or third-party inspection reports) directly with the supplier before placing an order.

Vlwin Machinery Industry Co., Limited operates from No. 6 Mengxi Road, Zhenjiang City, Jiangsu Province, China (postal code 212000). The supplier is listed on the platform with a harbour trust tier, which indicates basic verification but does not confirm specific certifications, production capacity, or export history. The listing does not disclose the company's year of establishment, number of employees, or annual output, so buyers should request these details along with factory audit reports or third-party inspection credentials before committing to a large order.

The product listing describes the company as a manufacturer of precision-engineered iron foundry products, covering ductile castings for automotive, pipeline, pump, and heavy machinery sectors. The supplier states that castings are available in weights from 2 kg to 500 kg per unit and are packed in reinforced wooden crates for international freight. No specific MOQ, pricing, lead time, or certification documents (such as ISO 9001 or material test certificates) are provided in the listing, so these should be confirmed directly with Vlwin Machinery Industry Co., Limited during the inquiry stage.
