Infrared Curing Oven & Infrared
Type Oven System – Autocoat Engineering
Autocoat Engineering manufactures Infrared Curing Ovens — electric infrared type oven systems designed to cure or dry water-based or high-solid stains, sealers and top-coats. Fast, energy-efficient, eco-friendly and easy to integrate with existing conveyor lines. India’s most experienced IR oven manufacturer since 1985, based in Thane, Maharashtra.
About Infrared Curing Ovens
Infrared Curing Ovens are designed to cure or dry water-based or high-solid stains, sealers and top-coats using electric infrared elements. High velocity flash-off sections enhance the curing process, making the system faster and more effective than conventional hot-air ovens for many applications.
Engineered to fit over your existing conveyor or built as an integral part of your new finishing system, Autocoat infrared drying tunnels are economical, reliable and easy to install. They emit no regulated pollutant gases — making them one of the most environmentally friendly curing solutions available for industrial paint finishing.
Autocoat Engineering is the most experienced Infrared Curing Oven, Infrared Powder Curing Oven and Infrared Paint Curing Oven manufacturer in India since 35 years — with wide experience across different material handling configurations, product sizes and production volumes.
Advantages of Infrared Curing Oven System
The Infrared Curing Oven system delivers six distinct advantages over conventional heating methods:
Higher Production Speed
Infrared energy penetrates the paint film directly — enabling significantly faster cure times compared to conventional hot-air convection ovens, boosting throughput and line speed.
Space Considerations
Compact infrared drying tunnels occupy a much smaller footprint than conventional ovens for equivalent throughput — ideal for facilities where floor space is limited or at a premium.
Presentation of Parts
Infrared elements can be precisely positioned around complex part shapes — ensuring uniform cure across all surfaces without the airflow turbulence of convection systems.
Precise Control
Non-contact temperature sensors and vertical/horizontal zoning provide the optimum in process temperature control — adapting easily to different part types and paint systems on the same line.
Lower Capital Cost & Maintenance
Infrared ovens have lower capital costs than equivalent large conventional ovens, and their simple resistance element design means fewer moving parts and significantly lower maintenance requirements.
Environmentally Friendly
Infrared Curing Ovens emit no regulated pollutant gases — making them one of the most environmentally responsible choices for industrial paint curing and drying operations.
Electric Infrared Type Ovens
Electric ovens use electric infrared elements — or sources — as the heat generator. 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, emitting infrared radiation that is directly absorbed by the paint film.
All well-designed electric infrared ovens exhibit the following six key characteristics:
- Vertical & Horizontal Zoning To provide an effective, flexible and efficient application of electric infrared heating to the specific process — adapting output to the exact requirements of each zone.
- Precise Element Layout & Distribution To incorporate shape factors, overcome edge effects and provide greater flexibility in heating different component geometries on the same line.
- Insulated Element Wiring To provide additional life — significantly extending the service life of the infrared elements and reducing the frequency and cost of element replacement.
- Non-Contact Temperature Sensors For control — to provide the optimum in temperature regulation without contact with the painted surface, ensuring accuracy and repeatability.
- Rigid, Non-Vibrating Structure To extend the life of the elements — a robust, stable oven frame prevents vibration-induced element damage and ensures consistent emitter positioning over the system’s lifetime.
- Custom Control To meet the specific needs of the process and the operators — including programmable zones, speed-linked power adjustment and integration with conveyor control systems.
Autocoat Infrared Drying Oven Systems are designed and built to your specific requirements for part size, production rate and thermal characteristics. Each system is AutoCAD engineered with full consideration of the component shape, coating type, conveyor speed and available space — ensuring the most efficient and economical infrared curing solution for your exact application.
