Product Specifications & Design Features

• Product Name: Electric Vehicle (EV) Armrest Box / Center Console Hinge
• Material: High-Carbon Steel or Powder Metallurgy Steel for superior strength and fatigue resistance.
• Primary Process: Precision Stamping, CNC Machining, followed by robotic welding for consistency.
• Surface Finish:Black Electrocoating (E-Coat) or Black Oxide. Provides corrosion resistance, a uniform matte appearance, and a slight lubricity for smooth movement.
• Key Design Features:
  • Reinforced Mounting Flanges: With precision pilot holes for secure, rattle-free installation.
  • Integrated Rotation Axles: Paired with locknuts to maintain precise torque and prevent loosening over time.
  • Optimized Geometry: Designed for a specific opening angle (e.g., 60-90°) and dampened motion, preventing abrupt drops.
• Durability Testing: Rated for a minimum of 20,000-30,000 cycles without loss of function or excessive play.
• Application: Primarily for EV center console armrest lids, also suitable for glove boxes, storage tray covers, and foldable tables.
