Import Aluminum Die Cast Parts For Home Appliance — Buy in wholesale FOB from Supplier in China

Dongguan Zhonghui Precision Die Casting Technology Co., Ltd. manufactures aluminum die cast parts for home appliance applications using ADC12 and A383 aluminum alloys, corresponding to the AlSi11Cu3 composition family. These alloys provide excellent castability, thermal conductivity, and machinability for components including housings, brackets, and functional parts. High-pressure die casting is the stated manufacturing process, enabling thin-wall geometries and complex internal features with dimensional accuracy typically held to IT11-IT13 grade. The supplier indicates OEM and custom manufacturing capabilities, suggesting toolmaking and secondary machining operations are available in-house or through controlled partnerships.

ADC12 alloy contains approximately 9.6-12.0% silicon, 1.5-3.5% copper, with maximum 1.3% iron and 0.3% magnesium, balancing fluidity, strength, and corrosion resistance for non-structural appliance components. A383 offers slightly better corrosion resistance than ADC12 with comparable castability, making it suitable for humid-environment applications such as washing machine internals and refrigerator compressor housings. Standard die casting tolerances for critical dimensions typically achieve ±0.05mm for small features up to 75mm, with linear dimensional tolerance of ±0.2% for larger castings depending on part geometry and die temperature control. Surface finish as-cast typically reaches Ra 3.2-6.3 micrometres, sufficient for most painted or powder-coated appliance exteriors without additional finishing.

Primary applications span washing machines, refrigerators, air conditioners, and kitchen appliances where aluminum's light weight and heat transfer properties reduce energy consumption and assembly cost. Buyers typically include original equipment manufacturers, tier-one appliance brand suppliers, and aftermarket replacement part distributors. The supplier's location in Dongguan City, Guangdong Province, places it within China's most concentrated die casting manufacturing region, with established supply chains for tooling steel, aluminum ingot, and surface treatment chemicals. Buyers should confirm with Dongguan Zhonghui the exact alloy specification per part number, die life commitments, secondary operation capabilities including CNC machining and surface finishing, and any existing appliance industry customer approvals or certifications held.

Dongguan Zhonghui Precision Die Casting Technology Co., Ltd. operates from No. 66, Weijian Road, Chashan Town, Dongguan City, 523380, Guangdong, China. The supplier holds a harbor trust tier classification with no recorded response rate or average response hours in the available platform data. The company name indicates specialization in precision die casting, suggesting investment in high-pressure die casting equipment and associated quality control infrastructure, though specific machine tonnages, cell count, and annual casting capacity are not disclosed.

The listing presents the company as serving global buyers with competitive pricing for aluminum die cast appliance components. No quality management certifications such as ISO 9001 or IATF 16949 are mentioned, nor are specific customer names, export volume data, or years in operation provided. The supplier's product range appears focused on home appliance applications rather than automotive or aerospace, which may indicate equipment and expertise calibrated to shorter production runs and faster tooling turnaround. Buyers should request facility audit reports, equipment lists, and sample parts with dimensional inspection reports before committing to production orders.
