The water-cooled vulcanizing press is engineered for speed, portability, and high-performance splicing. Constructed from lightweight aluminum alloy, it features a compact design and quick assembly, making it the ideal solution for rubber conveyor belt jointing on-site.

This is a heavy-duty sectional vulcanizer widely recognized in the industry for its durability, lightweight build, and suitability for use in harsh mining environments. Designed for full splicing coverage, whether fabric belts or steel cord belts, it supports both single-unit and multi-unit configurations based on belt length. Compatible with a variety of splice shapes, including skive, rectangular, and chevron joints, the vulcanizer offers a major advantage with its rapid cooling system.

Unlike traditional vulcanizers that take 4-5 hours to cool naturally, this vulcanizing press cools to below 70°C within just 15-20 minutes, significantly reducing repair time and allowing faster return to operation. This makes it especially valuable for field repairs or projects involving dozens or even hundreds of splices, where every minute saved is a major production gain.

Important Notes

Models can be customized upon request to meet specific requirements, including custom dimensions, rectangular configurations, various platen arrangements, or higher working pressure ratings. For more information, please contact us or your local EPNUO representative.

Vulcanization heating time should be adjusted based on the thickness of the conveyor belt.
Splice length must comply with relevant industry standards.
When placing an order, please specify the product model, specifications, belt width, belt type, and required vulcanizing pressure.
Optional electric pressure pumps are available upon request.
Key Components Spare Parts
Platens: Designed with a flexible, innovative structure combining an extruded plate, silicone heating elements, and durable composite insulation materials. Each plate conforms to belt irregularities, ensuring uniform pressure and splice quality. Maximum operating temperature is 200°C.
Frame: Ergonomically designed with optional handles for easier handling and setup.
Pressure & cooling system: The pressure bag delivers even surface pressure across the joint. Integrated cooling channels within the pressure plate allow for rapid water-cooled heat dissipation, minimizing downtime.

Yes, but it’s essential to ensure the vulcanizer matches the belt material, whether fabric, steel cord, or rubber, as well as the required temperature, pressure, and platen size for effective splicing.

Conveyor belt vulcanizers are widely used in mining, metallurgy, coal, cement, chemical processing, and other bulk material handling industries.

For example, in coal mines, vulcanizers are used to repair and join belts transporting coal. In cement plants, they help maintain conveyor systems critical to the production line.

Vulcanizing temperature and duration depend primarily on the belt material and thickness. For standard rubber conveyor belts, the typical vulcanizing temperature ranges between 140°C and 150°C. As a general rule, allow approximately 4 minutes per millimeter of belt thickness to ensure proper curing.
