Import Aluminum Die Casting Part — Buy in Bulk from Supplier in China

Rongzheng (HK) Mold Co., Ltd. produces aluminum die casting parts at its facility in Shenzhen, Guangdong, leveraging proximity to China's dense manufacturing corridor. The die casting process employed yields components with thin-wall capability and repeatability suited to high-volume production runs. Exact alloy designation and as-cast tolerances are not stated in the listing, so buyers should request material certification and dimensional inspection reports before confirming orders. The supplier's address at No.53 Xifang Villa Area, Songgang Town, Bao'an District, places it within the Pearl River Delta logistics network with established port access via Shenzhen or Hong Kong.

The parts are formed from aluminum alloys typically selected for castability and structural efficiency in automotive and electronics housings. ADC12 and A380 represent standard die casting grades in this region, though Rongzheng's specific alloy procurement should be verified directly. Die casting permits complex geometry with reduced secondary machining, a cost driver that separates gravity casting from high-pressure die casting. Surface finish requirements, porosity levels, and heat treatment status are common specification gaps that buyers must close with the supplier. The listing mentions precision and durability without quantifying tensile strength, elongation, or hardness values, all of which require definition for engineering acceptance.

Target buyers include tier-two automotive suppliers, consumer electronics manufacturers, and industrial equipment makers seeking near-net-shape metal components. Applications span engine brackets, transmission housings, heat sinks, and structural enclosures where weight reduction matters. Trade terms referenced in the source include FOB and CIF shipping, with L/C and T/T payment options, though current availability should be confirmed given the supplier's 0.00 percent response rate and zero recorded average response hours. Buyers should treat this supplier as unresponsive until direct contact is established, and consider alternative sourcing channels within the same region.

Rongzheng (HK) Mold Co., Ltd. operates from No.53 Xifang Villa Area, Hongxing, Songgang Town, Bao'an District, Shenzhen 518105, Guangdong, China. The company name references Hong Kong but the manufacturing address is mainland Shenzhen, a common corporate structure for export-oriented Chinese mold and die casting firms. The supplier carries an imported tier classification and harbor trust tier, with no response data available, average response hours recorded as zero, and response rate at 0.00 percent. These signals indicate either a dormant listing, a data collection gap, or a supplier that does not engage through platform messaging. The listing provides no information about facility size, equipment inventory, quality system registration, or client references.

What the source description does state is limited to process claims and application sectors, without verifiable production capacity figures, certification body names, or inspection protocol detail. The address places the supplier in Bao'an District, a mature industrial zone with extensive die casting and mould-making supply chains, but proximity to clusters does not confer capability. Buyers should conduct independent verification through factory audit, sample order with dimensional report, or third-party inspection before committing to volume. The lack of response history suggests direct outreach by alternative channels may be necessary.
