Import Casting Parts — Buy in Bulk from Supplier in China

Ningbo Efforteam Machinery Co., Ltd. supplies precision steel casting parts designed for industrial machinery, with typical dimensions ranging from 50mm to 800mm in length and wall thicknesses between 3mm and 25mm. These parts are produced using sand casting and investment casting methods, achieving dimensional tolerances of ±0.3mm to ±1.0mm depending on geometry. The base material is typically ASTM A216 WCB or equivalent carbon steel, with options for ductile iron or stainless steel grades upon request.

The casting process follows standard foundry practices with controlled cooling rates to minimize porosity and shrinkage defects. Surface finish typically ranges from Ra 3.2 to Ra 6.3, suitable for machining prior to assembly. While the listing mentions ISO-certified processes, no certificate numbers or audit reports are provided, so buyers should request documented quality control procedures. Material traceability is implied through batch numbering, though not explicitly confirmed.

These casting parts serve applications in automotive transmission housings, aerospace brackets, and construction equipment components. Buyers include OEM manufacturers, aftermarket parts distributors, and engineering firms requiring custom-fabricated components. Trade terms offered include FOB Ningbo and CIF, with minimum order quantities likely starting at 100kg per part type. Packaging is standard wooden crates with rust-inhibiting film, though custom packaging can be arranged.

The company is categorized as an imported supplier with harbor trust tier, indicating verified export activity. No information is provided regarding years in operation, workforce size, or revenue. The listing confirms capability in precision machining and OEM casting services but does not state client names, certifications, or production capacity.

The supplier has no measurable response rate or average response time recorded, suggesting limited communication activity on the platform. Their operational strength appears to lie in production execution rather than sales responsiveness. Buyers should treat this as a factory-level source with documented export history but unverified internal quality systems unless confirmed directly.
