Rubber vulcanisation

The microwave technology has already been for a long time implemented in the plants for extrusion and vulcanization processes of rubber, for the production of pipes, gaskets, air tubes and other items that do not require molding vulcanization. The consequent advantages, in terms of heating, include higher speed and bigger depth, mainly for thicker profiles, thus ensuring higher productivity and energy saving (Watt/kg of processed rubber).

The mix is directly heated up, without thermic inertia of the curing tunnel walls or the steam, allowing an energy saving and reduction of the floor to cycle time, and smaller wastes connected to the heating time of the plants, thanks to the immediate microwave turning on.

Consequently, this technology helps to reduce installations and management costs, especially when compared with autoclave processes, and also environmental impact with regard to the salt-bath systems. Moreover, thanks to the advanced shielding and attenuation systems, also in line systems provide higher security at work, avoiding chemical risks of the salt-bath plants or risks of over-heating and high pressures of autoclaves.

Both prototypes and genuine production lines were constructed, having different power (8-12kW) and dimensions (6-20 meters) according to the desired productivity.
