About Rotational Moulding
INTRODUCTION TO ROTATIONAL MOULDING Rotational moulding, also known as roto casting or roto moulding, is a low pressure, high temperature manufacturing method for producing hollow, one-piece plastic parts. As with most manufacturing methods for plastic parts, rotational moulding evolved from other technologies. Currently rotational moulding is a very competitive alternative to Fiberglass, thermoforming and injection moulding for the manufacture of hollow plastic products. This is because it offers designers the opportunity to achieve the economic production of stress-free articles, with uniform wall thickness and potentially complex shapes OVERVIEW OF ROTATIONAL MOULDING Modern rotational moulding is characterized as being an atmospheric pressure process that begins with fine powder and produces nearly stress-free parts. It is an essential requirement that the plastic withstands elevated temperatures for relatively long times. As no pressure is used in forming the plastic, rotational m
