metal heating plate

Product Application

Home appliances: electric kettle, coffee machine, health pot, electric pressure cooker, air fryer.
Industrial equipment: commercial oven hot air module, laboratory constant temperature reactor, food processing drying equipment, heater heating module.

Product parameters

Material and structure:

Stainless steel (304/316): corrosion-resistant, high temperature resistant (800°C), polished or matte surface, suitable for food and medical equipment.

Aluminum substrate (anodized): thermal conductivity 237 W/(m·K), lightweight, surface anti-oxidation coating, suitable for small household appliances.

Nickel-chromium alloy (NiCr): temperature resistance 1200°C, strong oxidation resistance, high resistivity, suitable for industrial high temperature scenes.

Composite metal plate: stainless steel + aluminum layer (composite thermal conductivity), taking into account strength and thermal efficiency.

Power range:

Household model: 500W–2000W (electric kettle, air fryer, coffee machine, etc.).

Commercial/industrial model: 2000W–10,000W (industrial oven, metal heat treatment equipment).
​​Working voltage:
​​Standard voltage: 110V/220V AC (error ±5%), compatible with global power supply.
​​Low voltage adaptation: 12V–48V DC (vehicle/portable device).
​​Temperature control:
​​PID algorithm: temperature control accuracy ±1°C, supports program heating (such as gradient heating).
​​Sensor type: K-type thermocouple (wide temperature range -50°C–1300°C) or PT100 platinum resistance (high precision).
​​Temperature range: room temperature +10°C to 1000°C (depending on the material).
​​Dimensions:
​​Shape: flat, curved, customized (suitable for pot bottom, oven cavity, etc.).
​​Thickness: 1mm–10mm (ultra-thin design suitable for compact space, thick plate for industrial equipment).
​​​​Safety protection​​:
​​Anti-dry burning​​: Automatically cut off the power when the temperature is greater than the set value by 10°C (such as setting 300°C, the actual 310°C triggers protection).
​​Overload protection​​: Automatically reduce the power when the current exceeds the limit, adapting to short circuit or external device abnormality.
​​Explosion-proof design​​(industrial grade): Passed CE/ATEX certification, suitable for flammable and explosive environments.
​​Life and reliability​​:
​​Conventional models​​: 5,000–15,000 hours (calculated based on 8 hours of continuous use per day).
​​Industrial-grade models​​: 10,000–20,000 hours (enhanced heat dissipation and anti-oxidation coating).
​​Core advantages
​​Durability and broad-spectrum adaptability​​:
​​Stainless steel material​​: acid and alkali resistant, wear resistant, suitable for food processing and medical sterilization equipment.
​​Nickel-chromium alloy​​: high temperature resistant (1200°C), anti-oxidation, suitable for extreme environments such as metallurgy and glass sintering.
​​​​High-efficiency thermal conductivity and uniform temperature:

Aluminum-based composite board: Surface temperature uniformity ≤±5°C, thermal efficiency of more than 90%.

Stainless steel heat sink: Reduce the risk of local overheating through heat conduction optimization design.

Precise temperature control and intelligence:

Supports multi-segment programming (such as heating → constant temperature → cooling), suitable for laboratory gradient reaction or industrial annealing process.

PID dynamic adjustment: Suitable for high-frequency temperature change scenarios (such as PCR amplification, material heat treatment).

Safety and easy maintenance:

Anti-corrosion coating (such as Teflon): Suitable for strong acid/alkali environment (laboratory/chemical industry).

Modular design: Convenient replacement of heating elements, reducing maintenance costs.

Lightweight and structural strength:

Aluminum substrate: Low density (2.7g/cm³), 40% lighter than stainless steel, suitable for portable devices.

Stainless steel frame: Shock-resistant, suitable for industrial vibration environment (such as heating of automotive parts).

​​Environmental protection and energy saving​​:
High heat recovery efficiency (metal has fast heat conduction) and complies with EU RoHS/REACH environmental protection standards.
