INFRARED TYPE OVEN (infrared curing oven SYSTEM)
infrared curing oven designed to cure or dry water based or high solid stains, sealers, and top-coats. High velocity flash off sections enhances the curing process. Engineered to fit over your existing conveyor or built as an integral part of your new finishing system, drying tunnels are economical, reliable, easy to install.
ADVANTAGES OF infrared curing oven system:
ELECTRIC INFRARED TYPE OVENS:
Electric ovens use electric infrared elements, or sources. Electric infrared sources are heated by current flowing through a resistance heating element. The element and the material surrounding the element are heated to an incandescent temperature.
All well designed electric ovens exhibit the following characteristics:
infrared curing ovens SYSTEM FOR DRYING:
Drying Ovens, also referred to as Dryers, are typically used for the removal of moisture from water-based coatings and adhesives. Drying Ovens are also used for removing water from the surface or interior of certain products or substrates. Infrared Drying Ovens System are designed and built to your specific requirements for part size, production rate and thermal characteristics.INFRARED TYPE OVEN FOR WATER-DRYOFF:
Water Dry-Off oven completely removes the residue water, film the parts after they leave the cleaning machine. This is especially important for applications where powder paints or solvent based paints are applied shortly after the parts leave the dry off. The dry off can be constructed as a convection oven or dehumidification dryer.
Autocoat Engineering is the most experienced infrared curing oven, infrared powder curing ovens, infrared paint curing oven in India since last 40 years. We have wide experience of manufacturing infrared curing oven IN INDIA with different material handling and different product size, and different production volume.
FAQ
Frequently Asked Questions
What is an infrared curing oven?
An infrared (IR) curing oven uses IR emitters — gas-fired or electric — to directly heat the paint film via electromagnetic radiation rather than heating the surrounding air first. The paint cures from inside out, dramatically faster than convection ovens, with major energy savings and a much smaller floor footprint.
How does IR curing differ from convection curing?
Convection ovens heat the air inside the oven, which in turn heats the part — slow and energy-hungry. Infrared transfers energy directly to the paint film and substrate. IR is typically 3–5 times faster, uses 30–50% less energy and works extremely well for thin coatings on flat or simple-shaped parts.
What paints can be cured with IR ovens?
IR ovens cure solvent-based paints, water-based paints, powder coatings, UV-curable inks and many speciality coatings. Some thick paint films or complex 3D parts may require an IR-plus-convection hybrid oven configuration to ensure uniform cure in recessed or shadowed areas.
Are IR ovens faster than conventional ovens?
Yes. Infrared ovens cure most coatings in 3–10 minutes compared to 20–40 minutes in convection ovens. The dramatic speed-up is useful for high-throughput production lines, small floor-footprint paint shops, JIT manufacturing setups and inline component painting in automotive part plants.
What types of IR emitters are used?
Short-wave (quartz tungsten), medium-wave (quartz halogen) and long-wave (ceramic plate, gas catalytic). Short-wave is fastest but harshest. Medium-wave balances speed and gentleness. Long-wave is best for plastics and heat-sensitive substrates. Autocoat selects the right emitter for your paint and substrate.
Can IR ovens be used for powder coating?
Yes. IR is widely used for powder coating cure — especially in pre-gel zones (to flow the powder before full cure) and full-cure stages. IR is significantly faster than convection for powder and reduces the powder-coating line floor space considerably, making it popular in modern automated lines.
Are IR curing ovens suitable for plastic substrates?
Yes, with careful emitter selection. Long-wave (ceramic) IR works well on plastics, MDF and wood without damaging the substrate. Short-wave IR can cause distortion or surface damage if not properly matched to the substrate's temperature limits. Autocoat handles this matching during design.
How energy-efficient are IR ovens?
Infrared ovens are typically 30–50% more energy-efficient than convection because energy goes directly into the paint film and substrate, not wasted heating large volumes of air. Faster start-up and shut-down further reduces idle losses, giving lower running cost per painted part.
What is the cost of an infrared curing oven?
The cost of an infrared curing oven varies depending on size, type, and automation. Key factors include oven length and width, emitter type (short, medium, long wave), conveyor speed, zone count, control system sophistication and any conveyor or robot integration. Contact us or send enquiry for exact cost.
Does Autocoat manufacture custom IR ovens?
Yes. Autocoat builds custom infrared curing ovens — flat-bed, tunnel, overhead-hood and combination IR-plus-convection types. Each oven is engineered around your paint chemistry, throughput target, floor layout, electrical supply and any integration requirements with paint booths or conveyor lines.
