The team at Global Roto-Moulding began back in farming and agriculture. However over the years, we’ve worked with industrial designers from the widest range of industries. Whatever the project, we push design (and where necessary, innovation) to manufacture to our customers specification and requirements.

How Rotational Moulding Works

The process of rotational moulding (roto-moulding) is quite straightforward. First, you need a hollow mould which is filled with granulated plastic that is then heated. The mould is then slowly rotated around two axes until the softened plastic has stuck to the walls of the mould. The mould rotates throughout the heating and cooling phase to avoid sagging or deformation. At Global, we use low-density polyethene plastic as it’s stress crack resistant, UV resistant, strong and durable.

Rotational moulding, or rotomoulding for short, is a plastics manufacturing method with many design advantages. In fact, the method has become so popular in the last decade, that it’s now one of the fastest growing sectors in the plastics industry.

“Rotomolding offers tremendous design flexibility, the ability to do short runs economically and in multiple custom colours, and it makes complicated shapes easily … the tooling costs are low, which means moulds are inexpensive … it’s ideal for low-volume production and product testing.”

Dave Carter, President of RotoMould Inc.


Rotomoulding has a long reputation as the best method for manufacturing polyethylene water tanks. However, recently, many manufacturers have started using the process to create plastic products for a wide range of other industries. From medical products to furniture, automotive and marine parts, agricultural tools, playgrounds, industrial garbage bins and more – the opportunities are endless!
Here are just a few of the design advantages of using rotomoulding for your next manufacturing project:

Greater durability

Rotomoulded products are made from one piece of hollow plastic, rather than welding or bolting together several parts. This means that your products are less likely to fall apart due to weak joints or corroded weld lines.

Consistent wall thickness

The application of molten plastic is very precise, which means you can create a consistent wall thickness around your products. This reinforces the product’s strength and hardiness, even at corners and defined angles.

Wide range of shapes

Plastic is a very versatile and flexible material. You can make virtually any type of custom shape or design with it. Additionally, the rotomoulding process allows for complex shapes that are very difficult to make with other materials.

Lighter weight

Plastic products are lighter than other materials such as metal, wood or concrete. This results in cheaper transportation costs, easier and less expensive installation because not as many people are required, and products that are easier to lift for the end user.

Lower production costs

Rotomoulding is a very cost efficient manufacturing method because the moulds are inexpensive to make and the process is highly scalable. Products are made using a single mould, which can be reused multiple times. Plastic is also a very cheap material to source.

Resistant to rust, corrosion and UV rays

One of the biggest design advantages of plastic is that it doesn’t rust or corrode like steel. Global’s products are also boosted by UV stabilisers, which help to protect them from harmful UV rays and degradation by the sun.

Variety of finishes, textures and colours

With rotomoulding, you can achieve a number of different finishing textures that add depth and dimension to your product. From smooth and shiny to rough and textured. You can also add logos and graphics and even add speckles and metallics to your poly mix.

Safer for humans

Our poly mix complies with the Australian standards AS 2070 (plastics for food contact use) and AS/NZS 4020 (products for use in contact with drinking water), which means your end users can rest assured that their loved ones are safe when they use your products.
