Silicone spiral heating belts offer distinct advantages for plastic and rubber extrusion processes, making them a superior choice for extruder barrel and die heating:
1. Perfect Conformity to Cylindrical Surfaces
Seamlessly wraps around extruder barrels without gaps
Eliminates hot spots common with rigid mica heaters
Ensures uniform temperature distribution for consistent melt quality
2. Vibration and Impact Resistance
Withstands constant extruder vibration without failure
Spring-like structure absorbs mechanical shock
Maintains performance in high-vibration production environments
3. Easy Installation and Maintenance
Flexible design simplifies installation on long barrel sections
Allows quick removal for screw maintenance or cleaning
No need to disconnect entire heating system for barrel access
4. Superior Temperature Control
Excellent heat transfer to barrel surface
Compatible with PID controllers for precise temperature management
Rapid response to temperature adjustments
5. Durable in Demanding Conditions
Resists oil, chemicals and plastic residues
Withstands typical extruder ambient temperatures
Long service life even in 24/7 operation
6. Customizable Solutions
Available in various diameters for different extruder sizes
Can be manufactured with multiple heating zones
Optional integrated temperature sensors
Applications Include:
- Single and twin-screw extruders
- Plastic pipe and profile extrusion lines
- Rubber extrusion systems
- Blown film extrusion equipment
- Compound mixing extruders
By providing reliable, efficient heating with minimal maintenance requirements, silicone spiral heating belts help extruder operators achieve better product quality while reducing downtime and operating costs.
