Why Choose Kerone Microwave/Infrared Rubber Vulcanization Line

Kerone is known for delivering highly efficient, reliable and fully customized Microwave/Infrared Rubber Vulcanization Line solutions engineered after a detailed analysis of material characteristics, process goals and expected output requirements.
Rubber vulcanization has been a vastly popular application of Microwave Heating. While there are also types of cold vulcanization, microwave systems are always used for hot vulcanization. The continuous vulcanization of rubber profiles is the main application of microwave vulcanization systems. As the heat transfer in other heating systems only takes place through the surface of the product, the heating process is time consuming and can lead to negative effects like over-curing etc. In order to shorten down the vulcanization time and to avoid possible problems, these parts can be pre-heated using microwave ovens, as the radiation penetrates the rubber and heat the material from core to surface simultaneously and hence microwave curing is very fast.

Types and Features of Microwave/Infrared Rubber Vulcanization Line

Vulcanization is the process of converting natural rubber and similar elastic polymers into durable by cross-linking the polymer molecules, i.e. building additional bridges between them through the addition of sulfur or other equivalent “curatives.” Uncured natural rubber is sticky, deforms easily when warm, and is brittle when cold and hence is very poor in elasticity. Vulcanized materials are less sticky and have superior mechanical properties. The process is named after Vulcan, the Roman God of Fire. A vast array of products are made with vulcanized rubber including tires, sealings, shoe soles, hoses etc.

The process of rubber vulcanization can be carried out using the following two heating systems:

Infrared Heating System in Rubber Curing

Infrared rubber curing systems are highly efficient for the pre-vulcanization of rubber profiles and hoses. Positioned between the rubber extruder and the continuous vulcanization line, high-power infrared radiation pre-cures the surface of rubber products. This surface pre-curing improves dimensional stability and enhances surface finish quality.

Typically, infrared curing systems are approximately one meter in length and offer a heating capacity of around 30 kW. However, since rubber is a poor conductor of thermal energy, infrared systems mainly heat from the surface inward. This limitation has led to increased demand for microwave heating systems, which provide volumetric heating and ensure more uniform curing throughout the material.
