Industrial Aluminum Heating Plate
The rice cooker's heating plate is made by casting the heating tube inside, using an aluminum casting process with a centrifuge machine. It utilizes direct contact conduction and the high thermal conductivity of aluminum to achieve efficient and uniform heating of the inner pot. Combined with a magnetic temperature limiter, it provides precise temperature control for cooking rice and automatic keep-warm functionality.
Products Advantages
Complete In-House Production Line
Unlike many suppliers who outsource key manufacturing steps, we own and operate a complete heating plate production line. Our factory in Lianjiang, Guangdong Province, handles everything from raw material processing to finished product assembly. This vertical integration gives us:
Full quality control at every stage of production
Large production capacity to handle bulk orders
Fast delivery times without compromising quality
Cost advantages passed directly to our customers
High-Quality Materials
Heating Wire: We use premium branded heating wire from Midea's designated supplier, ensuring reliable quality with a power tolerance of ±5%. The resistance wire is typically made of nickel-chromium or iron-chromium-aluminum alloy, selected for its excellent oxidation resistance and stable electrical properties at high temperatures.
Magnesium Oxide Powder: We utilize 50-mesh medium-temperature magnesium oxide powder, which offers rapid heat conduction and excellent electrical insulation. The high-purity MgO powder ensures efficient heat transfer from the resistance wire to the outer tube while maintaining safe electrical isolation.
Aluminum Ingot: Our heating plates are cast using high-quality aluminum alloys such as ADC12, selected for their excellent thermal conductivity, lightweight properties, and corrosion resistance.
Rigorous Quality Testing
Every heating plate undergoes four rigorous inspections during the manufacturing process-significantly more than the two inspections typically performed by other manufacturers. This commitment to quality ensures our products consistently exceed industry standards.
Global Export Experience
Our products are exported to over 20 countries and regions worldwide, gaining recognition and trust in the international market. This global footprint reflects our ability to meet diverse quality standards and customer requirements across different markets.
Testing Standards
1. Process Inspection – Three Rigorous Tests
To ensure that the power of each heating plate meets the standard, we perform three key tests during the production process, strictly controlling the power error within ±5%:
* After powder filling: High-voltage resistance test to ensure the integrity and reliability of the heating element insulation layer.
* After tube shrinking: Resistance test to verify process stability.
* After casting: Finished product testing: Resistance and voltage tests to finally confirm that the power meets the standard.
2. Finished Product Inspection – Three Comprehensive Tests
Before each batch of heating plates leaves the factory, it must pass the following inspection items:
* Power measurement: Ensure that the actual power is within ±5% of the nominal value.
* High-voltage resistance test: Ensure electrical safety and eliminate the risk of leakage.
* Surface appearance inspection: No pores, scratches, deformation, or coating defects.
