Import Aluminum Die Casting — Buy in wholesale FOB from Supplier in China

Hebei Rongxing Driving Equipment Technology Co., Ltd. manufactures precision aluminum die cast components from their facility on the north side of Planning 4th Road in the Southern Industrial New Town of Jizhou District, Hengshui City, Hebei Province. Their stated specialisation is the ZL type elastic pin tooth coupling, a mechanical power transmission component designed for coaxial drive shaft systems. The coupling uses aluminum alloy ADC12 (A383) as its primary material, with torque transfer capacity ranging from 0.112 to 2800 kilonewton-metres depending on size selection. Working temperature spans -20 degrees Celsius to 70 degrees Celsius, with stated compensation for axial offset of 0.5 to 5 millimetres, radial misalignment of 0.3 to 1.5 millimetres, and angular deviation up to 0.5 degrees.

The ZL series employs nylon rod elements in longitudinal shear to transmit torque and provide damping, while the ZLD variant accommodates conical bores rather than cylindrical shafts. ADC12 (equivalent to A383 under ANSI/AA standards) is an aluminum-silicon-copper alloy with approximately 9.6 to 12.0 percent silicon and 2.0 to 3.0 percent copper, valued in die casting for excellent fluidity, moderate strength, and good machinability. The high-pressure die casting process achieves typical as-cast tolerances of CT5-CT7 for complex geometries, with parting line flash requiring trim press removal. Surface finish typically ranges 6.3 to 12.5 micrometres Ra in as-cast condition. Post-cast operations may include CNC machining of bores and keyways, balancing for high-speed service, and corrosion protective treatment where specified by the buyer.

These couplings serve industrial automation, automotive drivetrain testing, general machinery, and power transmission equipment manufacturers seeking compact torque transfer with some misalignment accommodation. The large torque range suggests applicability from small servo systems to heavy industrial drives. Buyers should note that the supplier's response rate shows 0.00 percent with zero average response hours recorded, so direct communication channels and alternate contact methods should be established early. The listing does not state MOQ, price, lead time, or specific packaging configurations. Payment terms, Incoterms, and certification status must be confirmed directly with Hebei Rongxing. The Hebei location offers inland manufacturing with potential port access via Tianjin for export shipments, though buyers should verify the supplier's export experience and customs documentation capability.

Hebei Rongxing Driving Equipment Technology Co., Ltd. is located on the north side of Planning 4th Road within the Southern Industrial New Town, Jizhou District, Hengshui City, Hebei Province, postal code 050000. The supplier holds harbor trust tier status. Their response rate is recorded at 0.00 percent with zero average response hours, indicating no platform-mediated inquiry history or non-responsive status. No founding date, registered capital, employee count, annual revenue, factory size, or named clientele appears in the available profile. The company is not described as holding ISO, IATF, or other quality system certifications in the provided data.

The supplier's product focus centres on mechanical power transmission components, specifically the ZL type elastic pin tooth coupling series manufactured by aluminum die casting. Their technical description shows engineering awareness of torque capacity, misalignment compensation, and temperature limits, suggesting some in-house design or application engineering capability. However, buyers should independently verify production equipment (die casting machine tonnage, CNC machining centres, balancing machines), quality control instrumentation, and any OEM customer references. The profile does not indicate export volume, international trade experience, or language capabilities for technical correspondence. Due diligence should include verification of business registration with the Hengshui municipal administration and confirmation that the stated address corresponds to an active manufacturing facility rather than a trading office.
