Product Description

Automatic Infrared (IR) Leveling & Drying Tunnel 01

The Infrared Drying Tunnel is an essential piece of equipment in modern coating processes, designed for the critical post‑application phase following roll coating, spray coating, or curtain coating. This machine specialises in efficiently volatilising diluents and eliminating bubbles from the surface coating, ensuring a smooth and even finish before proceeding to the final drying and curing stage.

As a precision‑engineered finishing system, it serves as the vital intermediate process between coating application and final curing (e.g., UV curing). Utilising medium‑wave infrared radiation, it provides gentle, penetrating heat that simultaneously levels the coating and accelerates drying from the inside out. This process is essential for achieving flawless, high‑gloss surfaces free of imperfections before the final cure.

Whether used as a standalone unit or integrated into a fully automated production line with spray coaters and UV curing machines, this tunnel delivers consistent, high‑quality results across a wide range of substrates and coating types.

Product Features

  • Integrated IR Leveling & Drying Process – Utilises advanced medium‑wave infrared heating technology to combine paint leveling and pre‑drying into a single, continuous operation. The heat rapidly penetrates the workpiece surface, allowing the paint to flow, level, and partially dry in a very short time.

  • Precise and Adjustable Control – Offers fully adjustable infrared lamp temperature (0‑250°C) and variable conveyor speed (5‑20 m/min) for tailored process parameters to suit different coatings and substrates.

  • Efficient Airflow System – Adopts axial flow fans that strengthen internal air circulation, making temperature distribution more uniform. This effectively removes paint bubbles and surface irregularities, significantly improving coating quality – resulting in a smooth, plump, and flawless finish.

  • Modular and Durable Construction – Features a robust, thermally insulated housing and a detachable leveling unit for efficient shipping, installation, and maintenance. The design ensures long‑term reliability and easy access for servicing.

  • Broad Material and Coating Compatibility – Designed for finishing coated surfaces of furniture panels, metal, glass, and PVC. Compatible with water‑based, UV, NC, PE, PU, and various solvent‑based paints, making it a versatile solution for diverse production environments.

  • Flexible Integration – Suitable for concave and convex curved surfaces as well as flat workpieces. Can be used alone or seamlessly integrated with automatic spray coaters and UV surface lacquer machines for a complete automated finishing line.

Advantages of Automatic Infrared Heating Tunnel

  • Superior Surface Finish Quality – Ensures a perfectly smooth, bubble‑free surface by enabling deep degassing and optimal paint flow, essential for high‑gloss mirror finishes.

  • Significant Increase in Production Speed – Dramatically reduces drying and leveling time compared to conventional methods, accelerating overall production line throughput.

  • Reduction in Operational Costs – Lowers energy consumption through efficient infrared heating and excellent insulation, while minimising labour and space costs via faster processing.

  • Flexible and Customisable Solution – Provides adaptable process settings (temperature 0‑250°C, speed 5‑20 m/min) and a modular design to meet specific production line requirements, ensuring consistent, high‑quality results.

Main Applications

  • Furniture & Woodworking: Cabinets, office furniture, solid wood, engineered wood products – final topcoat leveling and drying

  • Building Materials: Coated PVC panels, doors, decorative wall panels

  • Metal Fabrication: Metal sheets and components – leveling and drying paints

  • Specialty Surfaces: Coated glass, composite materials, and other demanding substrates

ZZCHRYSO Automatic Infrared Heating Tunnel – FAQ

A: It levels and dries coated surfaces – water‑based paints, UV, PU, PE, NC – on flat panels before final curing. Our ZZCHRYSO IR tunnel uses medium‑wave infrared radiation to gently heat from the inside out, eliminating bubbles, orange peel, and brush marks. It’s the critical step between coating application and final cure for high‑gloss finishes.

A: Hot air heats the surface from the outside in, which can trap solvents and cause bubbles. IR radiation penetrates the coating, heating it from within. This allows deep degassing, leveling, and faster drying without skinning over. For water‑based paints, IR is especially effective because it drives moisture out evenly.

A: Furniture panels (MDF, particleboard, solid wood), metal sheets, glass, PVC panels, and engineered wood. Working width: up to 1320 mm. Thickness: 2–80 mm. Minimum length: 300 mm. It handles a wide range of substrates used in furniture, building materials, and specialty finishing.

A: IR lamp temperature is adjustable from 0 to 250°C. You set the temperature based on the coating type (water‑based, UV, PU/PE) and substrate. The control system maintains precise, uniform heat across the tunnel.

A: Feeding speed is adjustable from 5 to 20 m/min. Conveyor power is 1.5 kW. You can match the speed to your coating line’s output – slower for thicker coatings or water‑based paints, faster for thin UV primers.

A: Yes. It’s designed as a modular unit. Place it after a roller coater, spray line, or curtain coater, and before a UV curing machine or cooling section. The 6000 mm tunnel length (approx.) fits into most line layouts. A detachable leveling unit simplifies shipping and installation.

A: Superior surface finish – deep degassing eliminates bubbles and orange peel, essential for mirror‑gloss finishes. Faster production – much shorter leveling and drying times than air drying. Lower operational costs – energy‑efficient IR heating and good insulation reduce power consumption, and you save floor space because drying happens inline. Flexible – adjustable temperature and speed work with water‑based, UV, solvent, and PU/PE paints.

A: Daily: clean IR lamps and reflectors (dust blocks radiation), check conveyor belt tracking. Weekly: inspect lamp condition (replace any that are dim or burned out), clean ventilation filters. Monthly: calibrate temperature sensors, lubricate conveyor bearings, test emergency stops. The thermally insulated housing and heat‑resistant conveyor are built for long life. We provide a full manual and spare parts support.

A: Absolutely. Water‑based paints require gentle, penetrating heat to drive out moisture without blistering. Our ZZCHRYSO IR tunnel is specifically designed for water‑based coatings, as well as UV, PU, PE, and NC. The adjustable temperature and speed let you fine‑tune for each formula.

A: Furniture and woodworking (cabinets, office furniture, doors), building materials (PVC panels, decorative wall panels), metal fabrication (coated metal sheets), and specialty surfaces like glass. Anywhere that needs fast, defect‑free leveling and drying before final curing.
