Technical summary
Zone-controlled heating to regulate thickness, dimensional stability and optical quality of film.
Typical applications
- Film orientation and stretching.
- Transverse and longitudinal zone control.
- Processes sensitive to surface temperature.
Key points
Non-contact heating
Infrared radiation transfers energy directly to the product surface.
Zone response
Power can be adjusted by zone according to geometry and process speed.
Application-based selection
The emitter model is defined by temperature, distance, surface and material.
Recommended inquiry data
- Material or product to heat.
- Heated-area dimensions.
- Distance between emitter and product.
- Target temperature and process speed.
- Number of control zones and available space.

Selection criteria
To select infrared emitters, total power is not enough: geometry, distance, material absorption and required uniformity must be reviewed.
