7.1 INTRODUCTION
Rotational moulding is a currently the fastest growing sector of plastic processing industry. In rotational moulding process, preweighted quantity of plastic powder is loaded in to the mould. The mould is then bolted in to the oven where it undergoes a biaxial rotation along with the heating of mould. After certain temperature the thermoplastic powder sticks to the
wall of the mould. The process is continued till the required thickness of the plastic part is obtained. After getting the required thickness, mould is cooled and demoulded (Antonio and Alfonso, 2004; Bharat et al., 2001; Crawford, 2002; Brent strong, 2006). The process is economical as several components can be produced in one piece, thereby eliminating the need of expensive fabrication. As the products are inherently stress free, components with good mechanical and service properties can be obtained. The products obtained from rotational moulding find extensive applications in various fields like agriculture, storage tanks, industrial equipment, medical devices, material handling, road/highways, automobiles, etc.
