Automatic UV Curing Machines & IR Drying Tunnels

Automatic IR Heating Tunnel for Paint Leveling & Solvent Flash-off

The secret to a glass-like surface. This Automatic Infrared (IR) Leveling Tunnel uses medium-wave infrared radiation to gently heat the coating from the inside out. It accelerates solvent evaporation and improves paint flow, ensuring a perfectly smooth, bubble-free surface before UV curing.

Product Description

The Taisan IR Heating Tunnel for Leveling is a mandatory thermal step in any high-quality finishing line. Working as a highly efficient Flash-off IR Dryer Tunnel, it gently heats the wet coating from the inside out, accelerating solvent and water evaporation while allowing the paint to flow out perfectly.

The TAISAN IR Leveling and Drying Machine is an essential intermediate step in high-quality finishing lines. While hot air dries the surface, Infrared (IR) Heating penetrates deep into the coating layer to heat the substrate and the paint simultaneously.

Why is IR Leveling critical?

  1. Deep Degassing: It forces solvents and air bubbles trapped deep in the paint to rise and escape before the surface hardens.

  2. Perfect Flow: The gentle heat lowers the viscosity of the paint, allowing it to ‘flow out’ and self-level, eliminating roller marks and orange peel. This machine is indispensable for producing High Gloss Mirror Finishes and is typically installed immediately after the coating machine and before the UV dryer.

Eliminate Surface Defects: This Paint Leveling IR Dryer is crucial for preventing bubbles, pinholes, and orange peel, ensuring a mirror-smooth high-gloss finish. Additionally, it can function as a Pre-heating IR Dryer to warm up substrates before coating, significantly improving paint adhesion.

Ideal For:

  • High Gloss Finishing: Ensuring a flat, mirror-like reflection.

  • Solvent Evaporation: Removing thinners from PU/PE/UV paints to prevent popping.

  • Pre-heating: Warming the board to speed up the final cure.

  • Bubble Removal: Allowing trapped air to escape from thick coatings.

Frequently Asked Questions (FAQ)

Q1:Why use IR instead of just Hot Air?

Hot Air dries the “skin” of the paint first, which can trap bubbles inside. IR heats from the inside, pushing bubbles out. For the best result, we often combine them (Hot Air Jet + IR Tunnel).

No. The temperature is carefully controlled. IR energy is absorbed mostly by the liquid coating and water molecules, effectively drying the paint without overheating the wood core.

It is strictly placed AFTER the Roller/Curtain Coater and BEFORE the UV Curing Machine. It is the “preparation zone” for the final cure.
