Import A380 Lock Transmission Rod, Die Casting — Buy in wholesale FOB from Supplier in China

The A380 Lock Transmission Rod from Junying Die Casting Co., Ltd. is an aluminum alloy die casting component manufactured at its facility in Dongguan, Guangdong, China. The part uses A380 aluminum alloy, a widely adopted die casting grade containing 7.5-9.5% silicon, 3.5-4.5% copper, and 2.5-3.5% zinc, balanced with aluminum, which delivers a good combination of castability, mechanical strength, and corrosion resistance. The rod is produced by high-pressure die casting, a process suitable for complex geometries and thin-walled sections in lock hardware, and receives a nickel plating surface treatment to enhance wear resistance and provide a uniform metallic finish for assembly with other lock components.

A380 alloy is the most common die casting aluminum in North American and Asian manufacturing, valued for its excellent fluidity, reduced shrinkage tendency, and acceptable ductility for functional hardware parts. The nickel plating layer, typically applied via electroplating with a thickness of 5-25 micrometres, provides barrier protection against atmospheric corrosion and galling during lock operation. The die casting process for this type of rod typically employs steel dies (H13 or equivalent tool steel) with cavity tolerances around ±0.05 mm for dimensions under 25 mm, though achievable precision depends on die wear, gate design, and process control. Standard material grades for comparable lock transmission rods in the industry include ADC12 (Japanese standard) and EN AC-AlSi9Cu3(Fe) (European standard), but A380 remains the predominant specification for export-oriented Chinese die casters serving hardware markets.

This transmission rod functions as an internal linkage component within mechanical and electromechanical locking systems, translating rotational or linear motion from the cylinder or actuator to the bolt or latch mechanism. Buyers include lock manufacturers, security equipment assemblers, and building hardware distributors in Europe, North America, and Southeast Asia. The supplier lists FOB, CFR, CIF, DAP, and DAT as available Incoterms, with payment options spanning L/C, T/T, M/T, D/D, D/P, and D/A. Packaging is specified as blister tray, carton, tray, or container, suggesting flexibility from individual piece protection through full container load shipment. The supplier's trust tier is harbour, with a 0.00% response rate and zero average response hours recorded, meaning buyers should expect to initiate contact and confirm current capacity, quoting, and engineering review timelines directly.

Junying Die Casting Co., Ltd. operates from No.3 Hongxing Road, Shajiao, Humen, Dongguan, Guangdong, China, 523936. Dongguan is a major manufacturing cluster for metalworking, mould making, and die casting in the Pearl River Delta, with extensive supplier networks for tooling, raw materials, and surface finishing. The company's trust tier is harbour, which represents a baseline verification level on the platform. The response rate is recorded at 0.00% with zero average response hours, indicating no tracked enquiry responses; prospective buyers should contact the supplier directly to assess current operational status, production capacity, and engineering support availability.

The listing identifies Junying as a lock transmission rod manufacturer with die casting as its core process, and A380 aluminum alloy as its specified material. The product range implied by this listing focuses on lock hardware components, though the exact scope of the company's output, annual capacity, number of die casting cells, in-house tooling capability, and secondary machining operations are not stated in the source data. Buyers should request facility audit information, quality management system certification (such as ISO 9001), and reference customers in the lock or security hardware sector to validate manufacturing competence. The supplier accepts multiple payment and delivery terms, suggesting experience with international trade, but buyers should verify current terms, minimum order quantities, and sample lead times directly.
