Thermoregulation and energy saving in vulcanization of latex

A new interesting application in Tempco for latex vulcanization plants, employed for the production of pillows and mattresses, for which we have supplied a small thermoregulation unit of ours.

These plants have usually a steam vulcanization section, inside a dedicated chamber, that however entails a significant loss of both energy and steam.

Aiming at increasing the efficiency of the vulcanization process, we have therefore developed a direct heating and thermoregulating system of the mould using pressurized water, also allowing a more effective and accurate control of the temperature and a more efficient use of the energy. The process requires in particular to heat the mould (weight of 1.000 kg in aluminium) and its content (35 kg of rubber and 25 kg of water) using pressurized water from a temperature of 50° C up to 100° C, in a cycle time of 30 minutes.

In this particular installation, heating is achieved using a steam heat exchanger, but it can be also obtained using electrical heating.

The project has been developed by Giovanni Caschetto, an engineer with a strong know-how and expertise in the field of latex products (mattresses and pillows), developed first in Italy and then in China. Overall, the system allows an energy saving of 50% in the production of the heat required by the vulcanization process. Thus this is a kind of solution that allows also small enterprises to implement an internally owned production line, with limited investments both in terms of installation and energy consumption.

  1. Dear Jacob, here the answer from Giovanni Caschetto, expertise in this field of process applicartion:
    Dear Jacob
    first few key information on how the heating equipment works
    It use pressurized water as heating fluid
    it is able to heat and cool molds
    it replaces the traditional steam Dunlop process
    it doesn’t need steam as heating source, it use only electric power
    compared with traditional Dunlop process it saves at least 50% of energy, up to 75%
    Of course, traditional Dunlop mold cannot be used with this equipment. It needs new aluminium molds properly designed
    It works both with pillow and mattress molds
    There is no limitation on the number of connected molds
    The size of this heating machine will be designed according the number and the size of the molds

  2. Small enterprises engaged in latex foam making using many size and shaped moulds at a time either by batch manual processing or continuous processing using a conveyor system also. With your type fixed heating how they can use your heating systems. With a 1000kg aluminium mould of King size mattress how they can run one mould of batch processing or with many number of different sizes of moulds.Do you have any modified heating setup for running such a factory setup.
