Flatbed Short-Wave Infrared Curing Oven for Water-Based Coatings – Batch & Sheet Processing

Flatbed Short-Wave Infrared Curing Oven for Water-Based Coatings – Batch & Sheet Processing

Composition of Production Line

• Fixed or sliding flatbed table (stainless steel or ceramic plate)

• Overhead movable IR lamp array (short-wave or medium-wave, customizable)

• Manual or motorized height adjustment mechanism (0–300 mm stroke)

• Digital timer with programmable intermittent pulsing

• Exhaust hood with variable-speed fan and carbon filter

• Touchscreen controller (store up to 50 recipes)

• Optional vacuum hold-down table for flat sheets

• Optional automatic lamp scanning carriage for uniform exposure

Product Description

This flatbed short-wave infrared drying oven is designed for batch processing and laboratory-to-production scale drying of water-based coatings on flat or slightly curved substrates, especially molded pulp sheets, paperboard, wood panels, and composite boards. Short-wave IR penetrates deeper into water-based coatings, driving out moisture rapidly without overheating the core of heat-sensitive pulp materials. The adjustable lamp height and programmable pulsing allow fine-tuning of drying intensity to prevent blistering or cracking. Built with a compact footprint and plug-and-play operation, it is ideal for R&D labs, small-batch coating lines, or as a stand-alone unit for quality control.

Technical Parameters

Application

• Drying water-based primer and topcoat on flat molded pulp sheets before thermoforming

• Post-printing drying for water-based digital prints on pulp sheets and paperboard

• Batch curing of water-borne varnish on wooden panels and furniture parts

• Laboratory testing and process development for new water-based coating formulations

• Small-lot production for custom printed pulp packaging or promotional items

Customization

Fully customizable table size (up to 3000×1500 mm), number and arrangement of IR lamps (2–12 tubes), lamp height stroke (up to 500 mm), programmable pulse sequences (up to 10 steps), and exhaust duct connection. Customizable vacuum hold-down grid for thin paper or pulp sheets. Also customizable safety enclosure with interlock switch for automated production. Optional customizable data logging (temperature vs. time) for ISO compliance.

Feature

• Short-wave IR deep penetration – dries thick water-based coatings without surface crusting

• Digital pulse-width modulation (PWM) for precise energy control

• Rapid response – full power in <1 second, cool-down in 5 seconds

• Ceramic reflector plates for uniform energy distribution (customizable)

• Removable lamp cassettes for quick maintenance

• Built-in over-temperature safety cut-off

• Quiet operation (<65 dB) with low air movement – no powder blow-off

• Optional scanning carriage for heating larger sheets beyond lamp array

FAQ

Q: Can this flatbed IR dryer handle molded pulp products with curved edges?
A: Yes – products up to 30 mm height can be dried effectively. For taller 3D products, we offer a customizable extended lamp clearance and optional side lamps.

Q: How do I avoid over-drying and scorching my pulp sheet?
A: The PWM control with short pulse duration (millisecond range) allows gentle heating. We provide customizable pre-set recipes for common pulp densities and coating weights. Also, a built-in infrared pyrometer option can control lamp power based on real-time surface temperature.

Q: Can I retrofit this unit to my existing coating line?
A: Yes – the flatbed can be integrated as a stand-alone manual station or with customizable conveyor adapters. We also offer a customizable pass-through tunnel extension for semi-continuous operation.
