Consumers of coated metals, wood, paper, glass, plastic and textile products are demanding more attractive, long-lasting, wear-resistant surfaces. Meanwhile, stricter safety and environmental standards are forcing manufacturers to look at new types of finishes and different technologies: technologies well-suited to both drying and curing the new finishes. These market forces are increasing the use of electric and gas infrared process heating.
There are numerous advantages in using infrared technology including:
Most of the energy in properly designed systems is directed to the surface, acting directly on the coating, resulting in faster product curing or drying and lower energy costs. Processing time can be 50-85% faster than convection ovens.
Time & Space Savings
Faster heating means shorter ovens, so Infrared equipment occupies less floor space than convection ovens. Infrared ovens can often be added to an existing convection oven and production line with little difficulty, and, since they are modular they can be enlarged or reconfigured as needs change.
Cleaner & Finer Product Finishes
Since Infrared heats the coating directly, there is no need to blow hot air. This often translates into superior surface finish and fewer parts rejects due to surface blemishes.
Electric Infrared emitters respond very quickly and can be controlled by microprocessors that quickly follow process changes. This is very important where the coating characteristics change from product to product.
Low Initial Cost & Maintenance
Electric Infrared ovens usually cost less than convection ovens. Emitters can be designed for long life, easy periodic cleaning, and minimal maintenance.
