Import Aluminum Alloy Die Castings — Buy in Bulk from Supplier in China

Kunshan JST Industry Co. Ltd. manufactures aluminum alloy die castings from its in-house die casting plant established in 2009. The parts receive sand blasting followed by clear anodizing as standard finish treatment, with dimensional tolerance held to plus or minus 0.02 mm. The supplier also maintains internal machining and heat treatment capabilities, enabling vertical integration from raw casting to finished component. Material options extend to stainless steel, carbon steel, alloy steel, and zinc alloy in addition to aluminum alloys, though this listing focuses specifically on aluminum alloy die castings for automotive parts applications.

The die casting process typically employs cold chamber high pressure die casting for aluminum alloys, with common alloy grades including ADC12 (Japanese standard), A380 or A383 (ASTM), and EN AC-46000 series. Typical as-cast tolerances of plus or minus 0.02 mm indicate precision tooling and process control, suitable for mating surfaces and features requiring minimal secondary machining. Sand blasting provides uniform surface preparation for anodizing, while clear anodizing generates a protective aluminium oxide layer 5-25 micrometres thick, typical for decorative and mild corrosion-resistant applications. The supplier states inspection equipment for material verification and dimensional control is in-house, though specific instrument types and calibration status are not detailed.

Primary buyers are tier-two automotive suppliers and food equipment manufacturers requiring medium-to-high volume cast components. The stated supply capacity is 5,000 pieces per month, with mass production lead time of 30-45 days after tooling approval. Sample delivery including tooling build is approximately 30 days. Packaging places individual pieces in foam bags, with 500 kg per wooden case. The FOB port is Shanghai. Buyers should confirm specific alloy designation, mechanical property requirements, and any PPAP or IATF 16949 quality system requirements directly with Kunshan JST Industry Co. Ltd., as these are not specified in the source data.

Kunshan JST Industry Co. Ltd. operates from No. 567 Middle Xinnan Road, Kunshan, Jiangsu Province, 215301, China. The supplier holds a harbor trust tier, with zero percent response rate and no recorded average response hours on the platform. The company established its investment casting and die casting plant in 2009, indicating over fifteen years of operational history in metal forming. The in-house capability spans casting, machining, and heat treatment, suggesting reduced subcontractor dependency for standard product routes.

The listing explicitly targets auto parts and food equipment sectors, with inspection equipment maintained internally. No quality system certifications (ISO 9001, IATF 16949), revenue figures, employee counts, or named clients are provided. Buyers should independently verify registration details, request factory audit access, and confirm whether the automotive division operates under automotive-specific quality protocols. The Kunshan location places the supplier within the Suzhou-Kunshan manufacturing cluster, with strong logistics access to Shanghai port approximately 50 km east.
