Rotational moulding is the process of creating hollow plastic parts/products, for example, water and fluid tanks, grit bins, road barriers and so on. If you have any questions about what we do e-mail at:

Rotational Moulding: The Process

We can use a range of popular industry materials such as Standard Polyethylene, Cross-linked Polyethylene, Polypropylene, Polyvinyl Chloride, Nylon/Polyamides and Foamed Polymers.

We remove the plastic products from the moulds by releasing the clamps that separate the two tool pieces.

Next the product is taken out and is rigorously inspected for any imperfections, if it passes this quality assurance test it is trimmed and shaped while warm to allow an easier overall process & a smoother more refined finish to the final product.

This is time when Captive nuts, studs and other fittings can be fitted/extracted from the plastic products while they are still warm.

Depending on the size of the product being moulded we can decide which machine would be the most efficient to use. We have two different machines that both have particular pro’s and con’s depending on the type of work we have for them.

Rotational Moulding

Our History

Jobec group have several subsidiaries, We offer services ranging from the manufacturing of products via rotational moulding, a welfare and toilet hire division and a sales division of commercial automotive products & components. Operational since 1997, We try to exceed expectations with our customers wherever possible.

Jobec UK Ltd can rotationally mould items up to 3 metres long by 1.5m wide by 1.5m deep, and process most commercially available materials in a vast range of colours and finishes.


Rotational Moulding – The Process:

Rotational moulding is the process of creating hollow plastic parts/products, for example, water and fluid tanks, grit bins, road barriers, canoes, boats, floating pontoons, etc. Rotational moulding produces strong durable products that are weather and chemical resistant and can last many years in harsh environments. The moulding process involves melting plastic powder to a semi-liquid state that is then spread evenly over the inside of a hollow tool during the rotation period. After cooling, the product reverts back to a strong rigid hollow structure.

The benefits of the rotational moulding process is a relatively uniform wall thickness throughout the product and secondly, the hollow moulding that can have design and structural advantages which are difficult or even impossible to achieve by other methods such as blow-moulding or vacuum forming.

The technology, tooling and finishing that we use makes rotational moulding an ideal choice for hollow products – such as rotationally moulded plastic tanks – with advanced benefits. Low cost, short lead times, intricate design features and little or no post mould finishing are all within the advantages of rotational moulding.

Extra strength, sound deadening and insulation properties are increased with foam filling, either as an inner skin or whole cavity. Threaded studs, nuts, handles, hinges, labels, locks and many other items can also be moulded in during process.
