Design & Product development
Rotational Moulding has many advantages over other methods of manufacture.
With our design and development capabilities we can ensure that your Product is brought to market economically, faster and is of the highest quality.
From a rough sketch we can take the Product through drawing, Cad design and modelling, prototyping onto full scale production often in a matter of weeks.
Add our tool making capabilities with our sister Company Turnell & Odell Ltd. www.toengineering.co.uk and electronic control solutions Crompton Components Ltd. www.cromptoncontrols.co.uk for a truly integrated manufacturer.
Greater design flexibility
Rotationally moulded pieces can be designed and manufactured to fit just about any space available. Often parts that are assembled from multiple pieces can be consolidated into one rotationally moulded part. This improves the design possibilities. The fewer the parts, the fewer chances for part failure.
Dramatic cost savings
Because there is no interior core to manufacture, tooling for rotationally moulded parts is less expensive than tooling for other types of moulding.
Consistent wall thickness
Traditionally, metal components are weakest at the corners - the exact areas where the parts endure the most stress. With injection moulding or blow moulding, it's difficult to achieve total consistency in wall thickness. With rotational moulding, the constant rotation allows the resin to coat every surface evenly.
A number of factors contribute to the superior strength of rotationally moulded parts: durable new plastics, consistent wall thicknesses, one-part construction and corrosion-resistance.
Shorter production times
We can usually design the piece, tool it and begin production in fewer than 3 months. Compare that to the minimum lead time of 6 months for injection moulding, and it's easy to see that rotational moulding brings your finished product to market dramatically quicker.
Easier to modify
Because of the relative simplicity of the tooling, minor alterations can be made to an existing mould to accommodate your changing production needs.
Ability to do small runs
With less expensive tooling, rotational moulding makes it possible to do smaller runs on products. In fact, many of our customers find it economical to do runs as small as 10 pieces.
Moulds can be machined, cast or fabricated from materials such as stainless steel or aluminium. Cast and machined moulds are best when exacting tolerances or cosmetic finishes are important to the finished product. Cast moulds offer a wide range of finishes from wood grain to a mirror finish. Fabricated moulds are more economical than cast or machined moulds, but offer less options for finish.
Stress Free / Low Pressure Process
Rotational moulding is a low-pressure process, and the strength required from the moulds is minimal. This results in its ability to produce large or complex parts on short notice, using low cost moulds.
The low processing pressure involved in rotational moulding has the added advantage of producing parts which are relatively stress free, as compared to other high pressure processes. This advantage of the process is especially important when considering large, load bearing parts in applications which must provide corrosion or stress-crack resistance.
Shorter Production Times
Products can be designed, tools made and production started in as little as 2 months. Injection and blow moulding can take 6 months or more. Rotational moulding can get a product to market faster and more economically than any other process.
