Large electric heating plates and heating platforms adopt tubular electric heating elements as heat sources. The heating tubes are precisely bent and shaped, then cast into large flat plates with molten aluminum inside molds. After precision machining, the cast aluminum heater features a smooth surface free of casting defects, enabling tight contact with heated workpieces. The surface load of high-power cast aluminum heating plates can reach 1–3 W/cm², with an operating temperature range from ambient up to 300℃, delivering evenly distributed heat output.

High thermal conductivity aluminum alloy material ensures uniform temperature across the heating surface and minimizes temperature difference over the equipment surface. It boasts long service life, excellent thermal insulation, high mechanical strength and anti-electromagnetic interference performance. Adding thermal insulation covers to heat dissipation surfaces can effectively reduce power consumption.

1. Heater body made of special molded aluminum alloy for even and flat temperature rise.
2. LED digital display for working surface temperature with accurate readings.
3. Fast, uniform heating speed, simple operation and safe usage.

Digital constant temperature sample platforms and heating plates are widely used for sample baking, drying and various thermal testing, serving as essential equipment for biology, genetics, biochemistry labs, analytical rooms and educational scientific research. They are also extensively installed on extruders, injection molding machines, vulcanizers, hydraulic presses, ultrasonic cleaning machines, semiconductor manufacturing equipment, cable machinery, petroleum processing equipment and more.

Bangqi Chuangyuan Technology provides customized heating platforms: Available materials include stainless steel, cast aluminum, cast copper, cast iron and 6061 aluminum alloy. Custom large-size platforms up to 3m × 2m are supported, with all custom dimensions acceptable.

1. Wipe the working surface thoroughly before use; no water droplets, dust, sediment or foreign residues are allowed on the surface.
2. Place sample bottles or other lab containers on the heating surface.
3. Switch on power supply, flip the power switch. Press the SET key to enter temperature setting mode when digital tubes flash. Press the △ key to increase set value and the ▽ key to decrease it; hold the keys for fast value adjustment. Press SET again to confirm and return to normal operating mode.
4. The heating plate must be supervised by dedicated personnel during operation.
5. Turn off the power switch and cut off power supply after finishing work.

1. Operating voltage shall not exceed 110% of rated voltage.
2. Wiring terminals must be arranged outside heating and insulation layers, and the equipment housing shall be reliably grounded.
3. Store cast aluminum heaters in dry environments. If insulation resistance drops below 1 MΩ after long-term storage, bake the heater in an oven at around 200℃ for 5–6 hours to restore insulation performance.
4. Secure the heater with proper positioning fixtures to ensure full tight contact between effective heating zone and workpiece; dry firing without load is strictly prohibited. Immediately remove surface dust and contaminants before reuse to avoid poor heat dissipation and shortened service life.
5. Prevent pollutants and moisture from penetrating magnesium oxide powder inside heating element terminals at the usage site to avoid electric leakage hazards.
