The Glue Curing Tunnel Oven is a high-efficiency, continuous thermal curing or radiation curing equipment specially designed for industrial production lines. It uses transmission systems such as belts, chains, or mesh conveyors to smoothly transport products coated, dispensed, or sprayed with adhesive through a narrow tunnel-shaped heating chamber. Under precisely controlled temperature and processing time, the adhesive is rapidly dried, hardened, and formed.

Application

Electronics and Semiconductor Industry

Used for conformal coating drying on PCB circuit boards, adhesive fixing of electronic components, and glue encapsulation of LED modules.

Automotive Electronics Industry

Used for adhesive curing of electronic control systems, vehicle displays, sensors, and critical automotive components.

New Energy Industry

Used for adhesive dispensing and curing in lithium battery pack assembly, as well as heating and curing of sealing adhesives for photovoltaic module frames.

Optical and Medical Industry

Used for rapid curing and shaping of UV adhesives or heat-curable adhesives in lens assembly, medical syringes, and precision instruments.

Hardware and Packaging Industry

Used for continuous high-efficiency curing of printing inks after screen printing and adhesive coatings after packaging processes.

Standards

Although tunnel ovens are usually highly customized (non-standard designs) according to specific product requirements, their manufacturing and operation must comply with relevant national and industry standards.

Safety and Electrical Standards

GB 5226.1 — Electrical safety of machinery standards

GB 19517 — National technical safety specifications for electrical equipment

Explosion Protection and Heating Standards

Since adhesive volatile compounds may be flammable, the equipment should comply with:

GB 20115 — Safety requirements for industrial heating equipment

Relevant explosion-proof design specifications

Temperature Control Standards

The temperature uniformity inside the oven is generally required to reach high-level or Class A uniformity. Industry requirements typically control temperature variation within ±2°C to ±3°C.

Environmental Protection Standards

The equipment should comply with industrial exhaust emission requirements and is usually equipped with dedicated exhaust systems, waste gas collection ports, or recovery interfaces.

Features

Continuous and Efficient Operation

Overcomes the limitations of traditional batch-type ovens. Materials continuously pass through the equipment, enabling seamless integration with fully automated dispensing production lines.

Multi-Zone Independent Temperature Control

The internal chamber is divided into multiple independent heating sections, such as preheating zones, high-temperature curing zones, and cooling zones. Different temperature profiles can be configured according to adhesive requirements.

Various Heating Mechanisms

According to different adhesive types, the equipment can be equipped with:

Hot air circulation heating

Far-infrared radiation heating

UV-LED ultraviolet curing system

Energy-Saving and Safety Design

Uses high-quality aluminum silicate insulation cotton to reduce heat loss. The equipment is equipped with electric lifting mechanisms for convenient maintenance, over-temperature alarms, and forced exhaust systems for volatile gases.
