The reduction box casting is a heavy‑duty industrial component used in gearbox and power‑transmission assemblies. It is produced from Ductile Iron GJS‑400‑15 or Gray Iron GGC 20‑25 in a resin‑sand casting process. The foundry can cast up to 20 ton single pieces and handles an annual volume of 30 000 metric tons. Each casting weighs between 300 kg and 2 800 kg and meets CT9 dimensional tolerance with a surface roughness of Ra 6.4‑12.5 µm.
Ductile Iron GJS‑400‑15 typically delivers a tensile strength around 400 MPa and a Brinell hardness of 180‑220, while Gray Iron provides good compressive resistance. Resin‑sand moulding offers excellent dimensional stability and reduces internal stresses. The casting conforms to ASTM, AISI, DIN, BS and JIS standards and is inspected with German Spectro spectrum analysis, ultrasonic and magnetic‑powder testing. Such specifications make the component suitable for mining equipment, heavy machinery, conveyors and other high‑load gear systems.
Buyers usually request OEM dimensions and surface‑finish tolerances to match their transmission designs. The supplier can provide mill‑test reports and certification copies on demand. Trade is typically conducted on FOB or CIF terms, with bulk shipments arranged after order confirmation. Prospective importers should verify the exact weight, tolerance and certification details before finalising the purchase.

Before placing an order, importers should request the latest material test report that confirms the GJS‑400‑15 or GGC 20‑25 grade, together with a mill‑test certificate showing compliance with ASTM, AISI, DIN, BS and JIS standards. It is advisable to obtain a dimensional drawing that details the CT‑9 tolerance and the expected surface roughness, and to confirm that the casting weight falls within the 300 kg‑2 800 kg range for the chosen part size.
The foundry ships from the Fengxian Economical Development Zone in Xuzhou; buyers should agree on Incoterms such as FOB Xuzhou or CIF a designated destination port. Given the annual capacity of 30 000 tons, a typical production lead time is two to four weeks after design approval, although larger 20‑ton pieces may require additional scheduling. Common payment methods include T/T in advance or an irrevocable L/C at sight, subject to supplier confirmation.
Third‑party inspection can be arranged through NATA‑accredited agencies to verify dimensional accuracy and surface finish prior to loading. The supplier’s ISO 9001 and AQA certifications support a systematic quality‑management system, and ultrasonic as well as magnetic‑powder examinations are performed on each casting. Importers should request the inspection report and the full set of certificates before shipment to ensure compliance with their own quality standards.
