Roto Moulding
Rotational Moulding, or roto moulding as it is commonly known is an extremely versatile plastic moulding which is a relatively cost-effective method of producing hollow plastic components. The process is ideal for the manufacture of simple or complex shapes and because wall thicknesses can be accurately controlled the process lends itself very well to a wide variety of applications ranging from simple products such as safety steps and grit bins to more complex products such as children’s slides, hairdressing furniture and even missile cases.
