Mica Band Heater

Mica band heater is a reliable electric heating element for injection molding machines, plastic extruders, and other cylindrical industrial equipment. It uses high-temperature mica insulation and a metal outer sheath to provide stable heat transfer and dependable barrel heating.

EaseWise provides three main designs for different installation requirements: Standard Split, One-Piece, and Nozzle. Customers can choose the suitable structure according to barrel size, heating area, installation method, and application.

Mica Band Heater Types

The three designs cover general barrel heating, small-diameter barrel heating, and injection machine nozzle heating.

Type	Main Features	Typical Application	Temperature
Standard Split	Open-end split structure, easy installation	General injection machines and extruders	Up to 450°C
One-Piece	Closed-loop structure, close barrel fitting	Small-diameter barrels and short heating zones	420–450°C
Nozzle	Compact closed-loop design for narrow spaces	Injection machine nozzle heating	Up to 420°C

Standard Split Mica Band Heater

The Standard Split Mica Band Heater uses an open-end structure that allows convenient installation and removal. It is suitable for general injection molding machines, plastic extruders, and applications where the heater needs to be installed without removing the barrel.

Common stock sizes are available, while non-standard inside diameter, width, voltage, power, and terminal configurations can be customized.

One-Piece Mica Band Heater

The One-Piece Mica Band Heater features an integral closed-loop structure without a side opening. It provides close contact with the barrel surface and is designed for small-diameter barrels and short heating zones.

This design must be installed from the end of the barrel. Custom sizes, voltage, power, terminals, insulation layers, and thermocouple holes are available according to application requirements.

Nozzle Mica Band Heater

The Nozzle Mica Band Heater is a compact heating element designed specifically for injection molding machine nozzles. Its small size and closed-loop structure allow it to fit narrow heating areas around the nozzle.

Stock sizes are limited, so most nozzle heaters are manufactured according to the required nozzle diameter, heating width, voltage, and power.

How to Choose the Right Heater

First, determine whether the heater is required for a general barrel, a small-diameter barrel, or an injection machine nozzle. Then confirm the required inside diameter, heating width, voltage, and power.

For general applications where easy installation is important, the split design is a practical choice. For small-diameter barrels and short heating zones, the one-piece design provides close fitting. For injection machine nozzles, the compact nozzle design is intended for smaller heating areas.

Frequently Asked Questions

What is this type of heater used for?

It is mainly used to heat cylindrical surfaces such as injection molding machine barrels, plastic extruders, and injection machine nozzles.

What is the difference between split and one-piece types?

The split type has an open-end structure for easier installation, while the one-piece type has a closed-loop structure and must be installed from the barrel end.

Can the heaters be customized?

Yes. Inside diameter, width, voltage, power, terminals, and thermocouple holes can be customized according to the application.

What information is needed for a quotation?

The most important information includes inside diameter, heater width, voltage, power, quantity, and application. A drawing or sample can also be provided for OEM production.
