The machinery for the processing of rubber which is nowadays available on the market has no devices to save energy; so far, all effort has been made to improve production and lower the price of the device.
So the energy efficiency of these machines is quite low. We have developed a radical change of our presses internally, using special insulating materials, which, moreover, are resistant to high pressure. Such changes have been made on 60% of our presses.
This kind of work is rather difficult, because it is very expensive and, moreover, it is also very difficult to operate on machines already built by others. 5
5) Nowadays rubber machine makers don't consider energy saving. Worthwhile material research and machinery modifications have been done without any help from machinery makers.
