What is Rotomoulding
Rotational moulding, or rotomoulding, is a highly versatile manufacturing process used to create seamless, hollow plastic products. It involves placing a powdered polymer into a hollow mould, which is then heated and rotated biaxially (on two axes) inside an oven. As the mould rotates, the plastic melts and evenly coats the interior walls, forming the desired shape. The mould is then cooled, and the finished product is removed.
​
Unlike other plastic processing methods, rotomoulding does not use pressure. This makes the process ideal for producing large, durable, and lightweight parts with uniform wall thickness and excellent strength. The slow rotation and absence of high pressure also allow for lower tooling costs and greater design flexibility, making it suitable for short production runs, prototyping, and customized designs.
​
Rotomoulding is widely used across industries. Common products include water storage tanks, road safety barriers, containers, playground equipment, furniture, and automotive parts. The ability to mould complex shapes, insert metal reinforcements, and create multi-layered products adds to its appeal.
​
Environmentally, rotomoulding is increasingly aligned with sustainability goals. Many products are recyclable, and the process generates minimal material waste. New innovations in bioplastics and energy-efficient ovens are further enhancing its eco-friendly credentials.
