3500W Rice Cooker Heating Plate Production Line
The production steps for the 3500W Rice Cooker Heating Plate are as follows:
1. First, the aluminum ingot is melted in the aluminum melting furnace into molten aluminum. The heating plate is then formed using a centrifugal casting machine.
2. The center hole of the hot plate is punched out using a punch press.
3. The heating plate is drilled and tapped using a drilling and tapping machine.
4. The heating plate is lathe-turned using a lathe.
5. The resistance and voltage are tested using a comprehensive tester to ensure they meet the requirements.
6. Ceramic beads are applied with glue for insulation.
7. A spot welder is used to weld the iron plates for installation and fixing.

What is the key point of heating plate
As experts with 20 years of experience in manufacturing heating element production equipment, Davinci understands that the production of a 3500W Rice Cooker Heating Plate hinges on four key factors:
1: Heating Wire Selection and Winding Precision
The high power density of 3500W places a significant strain on the heating wire. Nickel-chromium alloy wire must be used for its stable resistance, strong high-temperature oxidation resistance, and far superior lifespan to iron-chromium-aluminum wire.
Automatic Coil Winding Machine: This is our core area. High-precision winding machines ensure absolutely uniform spacing and consistent tension during the winding process.
2: Magnesium Oxide Powder: Magnesium oxide powder is a heat-conducting medium, and its quality directly determines thermal efficiency and insulation. Heating elements primarily use medium-temperature electrical-grade magnesium oxide powder, which offers excellent insulation properties.
Cartridge Heater MGO Filling Machine: Filling density is the most critical process. Our powder filling machine uses multiple vibrations and precise control to ensure a dense and uniform filling of magnesium powder within the tube. High packing density maximizes contact area, allowing heat to be quickly and evenly transferred to the entire tube wall, preventing local overheating and ensuring good electrical insulation strength.
3: Tube Shrinking Process
Tube shrinking is the process of compacting a loose structure into a solid, integrated whole. The shrinking machine must ensure highly consistent tube diameters after shrinking. Uneven shrinking can lead to varying densities of magnesium powder inside, creating weak points in thermal conductivity.
18-Stations Tubular Heater Shrinking Machine: After shrinking, the tube must be completely sealed to prevent moisture from entering the air. Wet magnesium powder can significantly reduce its insulation properties, leading to leakage or even short circuits.
4:Surface lathing process
The shape of the heating plate determines its fit with the pot base, directly impacting thermal efficiency.
Lathe Machine: A lathing machine can precisely align the curved surface of the heating plate to the curvature of the pot base. A loose fit creates air gaps, resulting in significant heat waste and uneven heating of the pot.
