Like several other forms of plastic manufacturing, rotomoulded products are created using thermoplastics, which can be melted and reformed multiple times without losing any strength and integrity. This allows expert plastic manufacturers like us to create an almost limitless range of shapes from thermoplastics, providing almost endless possibilities for your product. In short, if you can imagine it, we can create it for you.

Rotomoulding in the plastic manufacturing process

Rotomoulding is a form of plastic manufacturing that involves solid thermoplastic pellets being placed inside a hollow mould, which is rotated steadily while being gradually heated. The centrifugal force causes the pellets to melt, disperse and stick to the inside walls of the mould. Once it’s cooled, the result is a hollow, virtually seam-free shape with a consistently even wall thickness. Roto moulding is perfect for creating containers such as grit bins, materials handling products and safety steps, all of which are in our standard range of products.

Benefits of rotational moulding for plastic manufacturing

Unlike products manufactured using blow moulded or injection moulded processes, with rotomoulding there are no ‘stress points’ that is, parts of the product which are especially liable to break under physical pressure. Rotomoulding also allows for particularly distinctive shapes and other complex geometries to be made in a single, seamless piece, rather than built from several individually manufactured components. The roto-moulding process also means that different surface textures are possible, which opens up even further design potential for your plastic product ideas.
