Rotational molding for large-scale production of design items

Versatility of shapes and sizes

One of the main advantages of rotational molding is the possibility to produce in a fairly easy way, even rather complex geometric shapes.

Other moulding systems, to achieve the same results, would require much more complicated and expensive procedures in terms of time and personnel employed. 

In addition, the rotational allows you to create design items of any size, such as small decorative items, or furnishing accessories of great aesthetic impact.

Variety of surface finishes

Rotational molding of thermoplastic materials such as polyethylene allows a wide variety of solutions to customize the surface appearance of the product.

For example, thanks to the pigmentation process during the processing of the raw material, it is possible to give the article an intense and durable color.

Or, thanks to a quick surface treatment, you can easily apply extraordinary finishes with high gloss for a galvanized, nickel-plated, chrome-plated effect and others.

In addition to the treatment of smooth surfaces, rotational molding is easily suitable for the realization of textures in relief of the traditional type such as grooving, knurling and others, or designed from scratch by the designer.

Light and resistant articles 

With the same size, round-molded polyethylene design objects have a substantial advantage over their metal counterparts or other non-plastic materials: they are much lighter.

In fact, polyethylene has a specific gravity of about 0.94 g/cm3, which corresponds to about one-third of aluminium (2.7 g/cm3) and one-eighth of stainless steel (about 8 g/cm3)

This means that they can be easily transported, placed or stored elsewhere when not in use.

Low production and maintenance costs

The use of rotational moulding for the production of design items is economically advantageous throughout the whole life cycle of the product.

This is because the industrial process to obtain the finished product requires fewer phases (for example, it doesn't need painting and other surface processing) than traditional materials such as metal, wood or stone.

In addition, the low weight of the raw material makes storage, transport and logistics operations much less demanding, even for large objects.

Finally, the maintenance of rotomolded polyethylene design items is particularly easy, as the surfaces are resistant to UV rays, atmospheric agents, shocks and scratches.

Attention to the environment

Another aspect that greatly influences the choice of rotational molding of polyethylene for large-scale production of design creations, is its green nature.

In fact, today, an increasing number of designers devotes increasing attention to ecological issues and the impact of industry on ecosystems.

From this point of view, recyclable plastics such as polyethylene are often the first choice because they are characterized by production, use and regeneration cycles with a high environmental sustainability.
