Rotational Moulding Process

Plastic Mouldings’ rotational moulding process is fairly simple and can produce a variety of complex product shapes in any colour using materials such as polymers, polypropylene, PVC and low/medium/high density polyethylene.

Rotational moulding is used in conjunction with construction, offshore work, water treatment, agricultural services, street furniture, tanks, spray tanks, water bottles, marine use, mussel floats, pontoon floats, road safety and waste products to name but a few.

The manufacturing consists of loading the charge weight of the chosen material into the rotational oven which has a temperature of around 300c. The mould then rotates around the machine which evenly distributes the power and finally cooling to form the product.

These days the processes have more economic tooling costs, with the tools used in rotational moulding being made from steel or aluminium. This assists in creating stronger, lighter mouldings leading to an even wall thickness which is proven to be very durable.

To finalise the process we have our own environmental police and green processes to re-encompass any rejected product and end of line materials or returns, where we granulate and re-use them again with our aim being to dramatically reduce the volume of waste materials.

The remainder of the by-products are either re-used in the manufacturing process or sold on to third party companies, who then in turn recycle the same to produce a wide range of products.

Any remaining waste is removed using the IBC Shipping Method with industrial containers designed to transport and store granulated substances.
