The history of rotational moulding can be traced back to the 19th century, when a British arms supplier, R. Peters successfully secured a patent for the manufacture of artillery shells using a combination of biaxial rotation and the application of heat. In the early 20th century, American FA Voelke pioneered the manufacture of wax objects using the process and over the next decade or so, rotational moulding was to become adopted by other manufacturers too. By the 1930s, rotomoulding was even being used to produce hollow chocolate characters and Easter eggs.
But, it was not until the early 1950s that plastics were introduced to rotational moulding. In the early days, products were limited to dolls heads, road traffic cones, planters and marine buoys. However, during subsequent years, a wide variety of products, applications and materials have been introduced to the rotational moulding process. Globally, manufacturers within the USA and China account for a substantial proportion of rotationally moulded products. However, within Europe – Irish manufacturers are significant players within the industry. Today, Carbery Plastics' plant in Clonakilty, West Cork is recognised as a European leader in the design, development and manufacture of rotationally moulded products.
Process
Rotomoulding is superficially the simplest plastic manufacturing process. It consists of 4 separate stages:
Applications
Rotational moulding is ideal for a wide range of product applications, including storage tanks, environmental, containers, children's toys, construction products, product cases and equipment enclosures. In fact, the only limit to suitable rotomoulding applications is the imagination!
Benefits
Rotationally moulded products, typically exhibit a number of significant performance advantages over products manufactured using alternative processes:
Furthermore, the availability of both specialist and commodity polymers makes rotomoulding the ideal production process for an ever-growing number of product applications.
