We offer mica band heaters for plastic injection moulding machines. They both have their specific uses and careful selection should be made to ensure long life and premature failure.
Mica band heaters are widely used in industrial applications for heating cylindrical or flat surfaces.
-
What are Mica Band Heaters?
- Mica band heaters consist of a mica insulation plate wrapped around a metal sheath. The metal sheath provides structural support and electrical insulation.
- These heaters are commonly used to heat extruder barrels, injection molding nozzles, and other cylindrical or flat surfaces.
- Mica has excellent dielectric properties, making it suitable for high-temperature applications.
-
Construction and Features:
- The mica insulation plate is wound with a resistance wire (usually nickel-chrome) to create a heating element.
- The outer metal sheath can be made of stainless steel, brass, or other materials.
- Mica band heaters often have clamping mechanisms for easy installation and removal.
- They come with various termination options, such as leads, armoured cables, or terminal boxes.
-
Applications:
- Plastic processing machinery: Mica band heaters are commonly used in extruders, injection molding machines, and blow molding equipment.
- Packaging machinery: They provide uniform heat for sealing bars, cutting blades, and other components.
- Food processing equipment: Used for heating pipes, nozzles, and hoppers.
- Laboratory equipment: Mica band heaters are employed in analytical instruments and scientific devices.
-
Advantages:
- Fast and efficient heat transfer due to direct contact with the surface.
- Uniform temperature distribution.
- Easy installation and maintenance.
- Customizable to fit specific dimensions and wattage requirements.
-
Considerations:
- Proper clamping and insulation are essential to prevent heat loss.
- Choose the right wattage and voltage for your application.
- Regular inspection and cleaning are necessary to maintain performance.
Remember that specific details may vary based on the manufacturer and the intended application. If you need further information or have specific questions, feel free to ask! ?
We can supply both options with thermocouple holes, split designs and with different types of clamping styles.
We can offer sizes up to 2 metres diameter and 2 metres in length, please send us your enquiry, we would be pleased to quote. Delivery time for band heaters is typically 4 weeks.
