Aluminum Alloy Five-Star Foot Die Casting

Aluminum Alloy Five-Star Foot Die Casting, a core support component for office chairs, gaming chairs, and more, utilizes a one-piece die-casting process to deliver exceptional stability in a lightweight design. Its smooth five-star radial structure evenly distributes load, accommodates a variety of chair post diameters, and supports customized surface treatments, providing rock-solid support and a refined design expression for office and gaming chairs.

Product Features:

1. Material Empowerment: Lightweight, High Strength, Weather Resistance
Selected from high-quality aluminum alloys (such as ADC12 and A380), the density is only one-third that of steel, significantly reducing the overall weight of the chair.
With a tensile strength of 210–350 MPa, the chair boasts a strength-to-weight ratio superior to cast iron, ensuring long-term load-bearing (such as that experienced by high-frequency office chair use) without deformation or cracking.


2. Die-Casting Process: One-Piece Molding, Precision First
Die-casting in one step eliminates joint gaps, resulting in a denser internal structure (porosity ≤1%) and a 30% improvement in fatigue resistance.
Dimensional tolerances are strictly controlled to ±0.1mm, and the center hole and chair stem fit together with ≥99% accuracy, ensuring zero lag during installation.

 

3. Optimized Structure: Five-Star Mechanical Stability
A symmetrical five-star layout evenly distributes force, with a static load capacity of 250–500 kg (customizable), making it suitable for office chairs, gaming chairs, and more.
The curved chamfered footrests protect against bumps and enhance floor compatibility (compatible with wood floors, carpets, and tiles).


4. Diverse Surfaces: Enhanced Aesthetics and Durability
The original metal texture offers a matte or frosted finish (depending on the mold process), complementing the modern, minimalist design.
Optional Finishes:

  • Anodizing: Salt spray resistant for ≥480 hours, suitable for humid environments (such as medical chairs);
  • Electrostatic Powder Coating: Customizable colors (RAL color palette available), wear- and scratch-resistant;
  • Polishing: Creates a high-gloss metallic finish, enhancing the product's quality. 5. Flexible Customization: Adapts to all needs.
  • Center Hole Specifications: Supports mainstream chair stem diameters such as φ16/φ20/φ22mm, compatible with over 95% of chair accessories.
  • Tripod Parameters: Adjustable leg length, angle, and end shape (e.g., rounded or flat) to meet custom design requirements.

 

6. Transforming Applications: Versatile from Office to Gaming

  • Office: Conference chair and staff chair bases, balancing stability and lightweight.
  • Esports: Gaming chair bases, adapted for high-frequency rotation and heavy loads.
  • Medical: Mobile bases for nursing beds and testing equipment, meeting sterility and corrosion resistance requirements.
