Infrared Heat in Industrial Production
IR Provides Efficient Best-in-Class Performance
WECO’s infrared ceramic product offering delivers long-wave infrared radiation for a wide range of industrial heating and engineering applications. These applications include plastics thermoforming, paint curing, printing, and drying. In addition, the product line includes ceramic trough elements, ceramic hollow elements, ceramic flat elements, and ceramic infrared bulbs.
Industrial heating with infrared systems operates in a mobile, rapid, and flexible manner. As a result, manufacturers can easily adapt it to intermediate steps in composite manufacturing or curing processes. Furthermore, it can deliver significant savings in energy use and curing time. A key advantage of infrared technology is its ability to function as a radiative source that requires no transmission medium.
Moreover, infrared energy does not function as traditional heat alone; instead, it behaves as an electromagnetic wave similar to light. Therefore, it can travel through a vacuum without restriction. Because the system uses a non-contact heating method, it eliminates contamination risks such as dust that often occur in convective heating processes. In most cases, industrial heating with infrared systems does not require complex or onerous safety measures. However, very short wavelengths can produce high light intensity, so operators may require goggles or protective screening.
When selecting an infrared emitter, engineers should match the spectral absorption of the target material to the emitter’s output characteristics. For example, many polymers absorb energy effectively in the mid- to long-wave infrared range. Shortwave infrared heaters provide the fastest heat-up times. However, their higher power density can cause surface overheating or burning. Alternatively, lower power ceramic or quartz heaters deliver gentler long-wave industrial heating. Consequently, this allows deeper energy penetration and supports a more complete curing process over time.
