Anew heat recovery system has been developed for plastic molding machines to reduce heat loss from the surface of heating cylinder.In this system, a cover is attached to the outside of the cylinder so that a cylindrical annulus-gap is formed between the cover and the cylinder. Using a blower, air is sucked into the gap from an opening at one end of the cover, heated while it is flowing through the annulus and sent to a dryer to preheat air for the dryer. From measurements with heater temperature from 160 to 250℃, it has been revealed that electricity for heaters of molding machine and dryer decreased by 20 to 35% and the temperature above the cylinder was up to 80℃ lower than the conventional cover, indicating this system is useful both for energy saving and impovement of working environment.
