Plastic Parts Drying Tunnel Furnace

The Plastic Parts Drying Tunnel Furnace is an industrial-scale continuous drying system. It uses a conveyor belt to continuously transport plastic components through a constant-temperature heating tunnel, enabling rapid and uniform drying of moisture or curing of surface coatings within a short period of time.The equipment integrates an intelligent temperature control system and hot air circulation technology, making it a core drying unit in automated plastic processing production lines.

Product Applications

Moisture Drying:

Commonly used for rapidly removing residual surface moisture from plastic parts after cleaning, electroplating, or screen printing processes.

Coating Curing:

Used for heating, drying, and hardening surface coatings after plastic parts undergo spray painting, oil spraying, or UV coating processes.

Stress Relief:

Used for heat treatment of precision plastic products to reduce internal stress caused by injection molding and prevent deformation.

Adhesive Curing:

Accelerates thermal curing of adhesives used in plastic assembly parts, improving assembly efficiency.

Product Parameters

Product Features

High Efficiency and Energy Saving:

The equipment adopts an internal hot air circulation system, minimizing heat loss and consuming less energy compared with traditional drying ovens.

Uniform Drying:

The optimized heat distribution inside the tunnel combined with constant-speed conveying ensures consistent heating for every plastic component.

Intelligent Temperature Control:

Equipped with a PID digital microcomputer temperature controller, providing precise temperature regulation and over-temperature alarm protection.

Easy Operation:

Both conveyor speed and drying temperature can be adjusted steplessly, allowing easy integration with upstream production lines.

FAQ

Q1: What is the maximum temperature of this tunnel furnace? Will it damage plastic parts?

A1:The maximum design temperature is generally 200℃. During actual production, the temperature is accurately adjusted according to the heat resistance of different plastic materials, such as ABS, PP, and PC. The normal operating temperature is usually controlled between 60℃ and 120℃ to avoid damaging the workpieces.

Q2: Can the conveyor speed be adjusted?

A2:Yes. The equipment adopts a variable frequency speed control system, allowing operators to freely adjust conveyor speed according to the drying process requirements of different plastic parts.

Q3: How does the equipment ensure uniform temperature inside the tunnel?

A3:The furnace chamber is equipped with high-performance circulation fans and optimized air duct designs, creating continuous hot air circulation inside the tunnel and maintaining temperature differences within ±2℃ in different areas.

Q4: Is the tunnel furnace size fixed?

A4:No. The tunnel furnace is a customized product. The furnace length, width, and tunnel height can be designed according to the size of plastic parts, production capacity, and available factory space.

Q5: What safety protection measures does the equipment provide?

A5:The equipment is equipped with over-temperature alarm and power-off protection, leakage protection, conveyor overload protection, and emergency stop buttons to ensure operator safety and stable production.
