The Rubber Foaming Softening Tunnel Oven is an industrial tunnel-type heating system designed for the continuous foaming, vulcanization, drying, and softening treatment of rubber materials. It is widely used in continuous production processes requiring precise temperature control, uniform heating, and stable material properties.

Main Applications

1. Automotive Sealing Strips

Used for manufacturing rubber foamed sealing strips for vehicle doors, windows, and engine compartments.

2. Thermal Insulation Building Materials

Used for producing NBR/PVC foamed insulation pipes, insulation boards, and other thermal insulation products.

3. Footwear and Luggage Materials

Used for continuous curing and shaping of EVA or natural rubber foamed soles and luggage lining materials.

4. Sports Equipment

Used for manufacturing high-elasticity foamed products such as handle grips, yoga mats, and protective cushioning materials.

5. Industrial Cushioning Materials

Used for producing various vibration-damping, noise-reduction, and sealing foam pads for mechanical equipment.

Equipment Features

1. Precise Temperature Control

The equipment adopts multi-zone independent microcomputer PID temperature control, with temperature differences controlled within ±1°C, ensuring stable processing conditions.

2. High Uniformity of Rubber Foaming

The scientifically designed hot air circulation system ensures that both the rubber surface and internal core are heated evenly and simultaneously, achieving consistent foaming performance.

3. Multiple Conveyor Options

According to different production processes, the oven can be equipped with:

PTFE (Teflon) mesh belt

Stainless steel mesh belt

Slat-type conveyor chain

to meet different rubber processing requirements.

4. High Efficiency, Energy Saving, and Environmental Protection

The oven body adopts high-density thermal insulation materials and is equipped with interfaces for:

Secondary combustion treatment of exhaust gases

Exhaust purification and collection systems

to improve energy efficiency and environmental performance.

5. Variable Frequency Stepless Speed Control

The conveyor speed can be precisely adjusted according to the foaming time requirements of different rubber formulations, ensuring optimal curing and foaming results.
