Metal Heating Plate——High-performance heating solutions
Metal heating plates are widely used in industrial, medical, laboratory and consumer fields. Their core performance depends on material selection, surface treatment and temperature control technology.
MOQ：1000PCS
Lead time：25days
Factory location: Zhongshan, Guangdong, China
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.
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.
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.
