Heating plate stainless steel mica injection molding machine heating coil 380V electric heating sheet 220V electric heating ring heating plate
Based on the keywords you provided, you are looking for stainless steel mica electric heating coils/heating plates used in plastic molding machinery such as injection molding machines and extruders. These products support non-standard customization and can meet different voltage (such as 220V, 380V, etc.) and power requirements. Combined with your location in Jiangsu Yangzhou and the surrounding industrial belt, we have compiled the following core product information and purchasing suggestions for you:
1. Core structure and performance of the product
Stainless steel mica heaters typically use a 0.3~0.5mm stainless steel plate as the shell, with a high-insulation, high-temperature-resistant mica plate as the core inside, and evenly wound nickel-chromium alloy resistance wire as the heating element.
Temperature resistance and power: The maximum working temperature is usually between 600°C and 800°C, and the maximum power load is generally 2.5W-3.5W per square centimeter.
Main advantages: reasonable structure, uniform heating, fast heat dissipation, good insulation performance, high voltage resistance, and long service life.
Various shapes: Can be processed into ring, plate, sheet, cylindrical, and other special shapes according to requirements.
2. Recommended high-quality suppliers nearby

3. Customization and purchasing notes
When contacting manufacturers for quotes or placing orders, it is recommended to confirm and provide the following parameters in advance so that manufacturers can quote accurately:
Dimensions: Inner diameter/outer diameter (mm), width/length (mm), thickness, etc.
Electrical parameters: Working voltage (such as 220V or 380V) and required power (W).
Installation details: Wiring method (terminal posts, high-temperature wires, ceramic connectors, etc.), lead wire length and position.
Special requirements: Whether holes need to be opened (square holes/round holes), thermocouple hole position, whether insulation devices or sintered infrared (can save about 35% electricity) need to be added, etc.
4. Installation and safety precautions
Tight fit: During installation, ensure that the heating coil/plate fits tightly against the heated body (such as the barrel). The heated surface must be flat and complete, without unevenness, to prevent local overheating and burn-through.
Waterproof and moisture-proof: This product is non-waterproof in structure. During storage and use, it is strictly prohibited to contact oil, water, or plastic pellets to prevent electric leakage.
Standard wiring: The wiring part should be placed outside the heating layer and insulation layer, and the shell must be effectively grounded; the working voltage must not exceed 10% of the rated value.
Avoid frequent disassembly: After heating use, repeated disassembly should be avoided as much as possible to prevent breakage of the internal alloy resistance wire, which affects service life.
