Import Auto Castings — Buy in wholesale FOB from Supplier in China

Dalian Etdz Xiupu Science Co, Ltd supplies auto castings in ductile iron, grey cast iron and aluminium alloy for powertrain and chassis applications including engine blocks, cylinder heads, transmission housings and brake components. The supplier states precision tolerance compliance with IATF 16949 automotive quality standards, with mechanical properties validated through tensile and hardness testing. Material options cover SG iron (ductile iron) for components requiring higher elongation and impact resistance, grey iron for vibration-damping applications, and aluminium alloy where weight reduction is priority. Buyers should confirm the specific grade designation for each alloy family, as ASTM or EN equivalents are not stated in the source data.

The casting process for ferrous grades typically involves green sand or chemically bonded sand moulding with automated pouring, followed by shake-out, shot blasting, heat treatment if required, and CNC machining to critical dimensions. Aluminium alloy castings may use gravity die, low-pressure die or high-pressure die casting depending on geometry and volume. Standard industry practice for automotive castings requires 100 percent dimensional inspection of datum features, with sampling plans for porosity verification by X-ray or ultrasonic testing. Surface finish and geometric tolerances must align with the customer's control plan under IATF 16949, including capability studies on critical characteristics before production approval.

These castings target OEM automotive supply chains, tier-one component manufacturers and aftermarket distributors serving vehicle production and service markets. Ductile iron grades suit steering knuckles, brake caliper housings and suspension brackets; grey iron dominates brake discs and engine blocks; aluminium alloys are specified for cylinder heads and transmission cases where thermal conductivity and mass savings justify material cost. Export packaging from Dalian typically employs wooden crates with rust preventive VCI coating for ferrous parts, though buyers should confirm specific packaging and sea freight arrangements with Xiupu Science directly. MOQ, price and lead time are not disclosed and require direct negotiation.

Dalian Etdz Xiupu Science Co, Ltd operates from Room 102, Gate 2, Building 21, No. 17 Shayue Street, Shahekou District, Dalian, Liaoning Province, China. Dalian is a major northern port city with established heavy industry and shipbuilding heritage, supported by container terminal capacity and rail connections to northeast China's industrial belt. The supplier holds an imported tier and harbor trust tier designation, with zero recorded response rate and no average response hour data, indicating limited trackable engagement through the platform.

The company profile does not disclose founding year, employee headcount, factory floor area, annual turnover, named OEM clients or specific certification document numbers. What is stated is a focus on IATF 16949-aligned production for automotive castings in multiple ferrous and non-ferrous alloys, with mechanical testing capability. Buyers should conduct due diligence including factory audit, quality system certificate verification and production process review before committing to volume orders, given the absence of detailed verification signals in the available data.
