BQ-L Aluminum Wheel Hub Low-Pressure Die Casting Machine

Overview
    Designed for automotive and commercial vehicle applications, this machine integrates gravity-assisted filling technology to ensure defect-free castings with superior surface finish and structural integrity. Its advanced automation and energy-efficient design cater to the demands of mass production while minimizing operational costs.

Core Technical Features

1. 1.Gravity-Assisted Filling
   The gravity-assisted filling system positions molds vertically at 90°, leveraging natural gravitational force to optimize molten aluminum flow. This reduces turbulence and porosity in critical areas like wheel spokes , achieving a first-pass yield rate. The gravity-assisted filling process is particularly effective for large-diameter wheels (18–24 inches), ensuring consistent wall thickness.

2. 2.High-Precision Pressure Control
   A multi-stage digital pressure valve system maintains deviations ≤1 mbar during filling and solidification. Combined with gravity-assisted filling, this guarantees uniform metal distribution, even for ultra-thin sections (3–5 mm thickness), meeting stringent automotive quality standards.

4. 3.Automated Workflow Optimization
   Robotic arms extract castings within 10 seconds post-solidification, while integrated mold spraying and slag removal systems eliminate manual intervention. 

5. 4.Energy-Saving Hydraulic System
   Variable frequency drives (VFD) reduce energy consumption compared to conventional systems. The gravity-assisted filling technology further minimizes material waste, with closed-loop scrap recycling achieving aluminum reuse.

6. 5.Durable Thermal Management
   Insulation furnaces feature a monolithic refractory lining, ensuring a service life of 5+ years. PID temperature control (±2°C) maintains molten aluminum oxidation below 0.5%, critical for high-gloss wheel surfaces.
