Manufacturing
With over 40 years’ manufacturing experience, you can expect reliable service and consistent product quality from Trifibre.
Storage & Drop Shipping
We take the hard work away from the logistics of shipping your rotational moulded products.
Rotational Moulded Products
We design and manufacture a wide range of rotational moulded products, including custom items made to your unique specifications.
Custom Plastic Products
Using Computer Aided Design (CAD) software, we work with your OEMs to produce rotomoulded products designs and prototypes to ensure your requirements are met prior to production. Once designs are finalised, we use polyethylene, polypropylene, polyvinyl chloride (PVC), nylon or polycarbonate in our rotational moulding process.
As the tooling used in rotomoulding makes it a cost-effective manufacturing technique, we offer competitive pricing for high-quality bespoke products.

The Rotomoulding Process
1. Charging
Also known as loading, the first step in the rotomoulding process involves raw material such as polyethylene (LDPE, HDPE, LLDPE, MDPE) being placed into the mould. This comes in a vast array of colours, and additives can be added for different requirements, such as UV protection and colour consistency.
2. Heating
The mould is then heated in an oven and rotated, causing the polymer to coat the mould walls. Rotation occurs on two or more axes rotating at different speeds and frequencies. This allows for an even wall thickness and clean finish for all rotational moulded products.
3. Cooling
The mould is then cooled while rotating to ensure even wall thickness. The product will experience a small amount of shrinkage, but this is catered for in the design of the mould. The shrinkage aids the removal of the product from the tool.
4. Removal
The product is then removed from the tool, and the finishing process begins. The parts are trimmed and allowed to cool further, with jigs sometimes used to prevent further shrinkage and achieve an accurate final product.
Rotomoulding FAQs
- What is rotational moulding?
-
Rotational moulding, also known as rotomoulding, is used to manufacture a diverse range of both simple and complex products. Rotomoulding uses sophisticated plastics moulding technology and is most often used to make hollow goods and components, such as hard plastic cases for storing electronic equipment, bins and containers, and children’s toys.
Rotomoulding is a popular method of manufacturing plastic products due to its affordability, and is used by a wide range of industries, as it delivers a precise and robust finish on every item. Computer controlled machines are used to ensure consistent quality for every unit produced.
- What is rotational moulding used for?
-
Rotational moulding is used to make a wide range of everyday items, including:
- Wheelie bins
- Litter bins
- Car dashboards
- Cup holders
- Aerospace components
- Traffic cones
- Road barriers
- Storage containers
- Pallets
- Planters
- Kayaks
- Buoys
- Children’s toys
- Lightweight exhibition cases
Take a look at some of the components used to make the Trifibre Pegasus exhibition case via rotomoulding.
- What materials are used in rotomoulding?
-
At the start of the rotomoulding process, metal moulds are created using aluminium, and the final product is made from polyethylene, polypropylene, polyvinyl chloride (PVC), nylon or polycarbonate. Steel is also used for creating some larger, simple products.
At Trifibre, we use a powdered polymer, usually polyethylene and virgin or recyclable materials, to make products using rotational moulding. Polyethylene is an ideal material for the rotomoulding process, as it does not deteriorate when exposed to extreme heat, allowing it to be easily melted and manipulated into a range of shapes and items.
- How does rotational moulding work?
-
Rotomoulding involves four key processes: charging, heating, cooling, and unloading. It’s a largely automated process, which means it can improve manufacturing times, while producing high-quality items.
Computer Aided Design (CAD) software is used during the development process to create accurate product designs and complex shapes. It can also predict how a rotomoulded product may react to external factors, such as extreme temperatures. CAD software also enables us to calculate weight and volume for accurate material usage and quotes.
The Benefits of Rotomoulding
- Affordable compared to the tooling used for other processes
- Extremely versatile
- Highly precise, thanks to CAD software
- Manufacture stress-free parts with uniform wall thickness and complex shapes
- Creates products that are stronger and more resilient under extreme conditions than those made using fabricating, fibre glass, injection, vacuum, or blow moulding
- Make lightweight yet durable and reliable products
- Design freedom with unlimited possibilities
- Create highly complex shapes
- Incorporate a range of details, including textured finishes, brand logos, symbols, and other lettering, as individual moulds are custom made for each project
