Oil Heating And Cooling Machines For The Rotational Moulding Of Plastics
Michael Wright, Roy Crawford
Forced air convection is the most common method for heating and cooling the mould in the rotational moulding process. However, it is generally accepted that this is a very inefficient method of heat transfer and so interest has grown in the use of more direct methods of heating and cooling the mould. This paper reports on an experimental study where oil was used to heat and cool the mould. This method is used commercially in a very small sector of the market, but there has never been a detailed study of its effectiveness. The results to be presented in this paper show that oil heating and cooling of the mould offers much higher thermal efficiency and reduced cycle times.
