• Multi-ply Composite Inner Pot: Multi-layer composite structure (e.g., steel-Al-steel) for even heating and high thermal efficiency.
• Precision Deep Drawing: Spherical thick inner pots providing larger heating surface area.
• Automated Spraying: High-quality non-stick coatings, non-toxic and durable.

1. Safety Performance Testing: Includes pressure testing (safety valves/relief devices), leak tests for air tightness, and dry-firing tests for thermostats.

2. Materials Laboratory: Coating durability testing (salt spray chambers) and physical performance testing of metal hardness and thickness.

3. Electronics & Lifespan Lab: Automatic PCB function tests, button lifespan simulation (tens of thousands of presses), and continuous cooking cycle tests.
