Rotomoulding also known as Rotational Moulding.

Established in 1981, the Trifibre Ltd group have over 32 years of experience and have gained an outstanding reputation for delivering bespoke and innovative, design led products. Tifibre provide a client focussed consultation service and are able to work with you to produce designs and prototypes, using state of the art CAD (Computer Aided Design) software, to ensure the individual requirements and needs of our clients are being met. Rotational Moulding machinery allows the highest quality products to be produced quickly, consistently and at the most competitive price. Rotational Moulding can be applied to a number of different markets and applications. We are UK Manufacturers and supply bespoke rotational moulding products to a wide range of industries.

With over 32 years of experience, the Trifibre team are able to provide an in-house design team, who work with you to develop your design ideas into product concepts. As a result, 3D CAD designs and prototypes are also provided to ensure that your requirements are being achieved. Once these designs have been finalised, we ensure that the manufacturing of your project is completed efficiently and successfully. As the tooling used in Rotational Moulding makes it a relatively cost effective manufacturing technique, we provide competitive pricing for quality products.

Why Rotational Moulding?

Durable and Reliable

Rotational Mouldings are inherently reliable, internal stresses are minimal and joints are eliminated. The materials are tough and resilient even under extreme conditions when compared to fabricating, fibre glass, injection, vacuum or blow moulding.

Unlimited Design Possibilities

Offering the opportunity to manufacture stress-free parts with uniform wall thickness and complex shapes. The process is extremely versatile. Parts can be manufactured with inserts moulded in and surface textures and effects reproduced with relative ease.

Low Cost

The tooling used in rotational moulding is produced from either steel or aluminium and is relatively low in cost when compared to tooling used for other processes, such as blow or injection moulding.

The UK’s Leading Manufacturer

Trifibre Ltd has over 30 years of manufacturing experience and provide a client focussed consultation and advice service from our professional and experienced customer service and sales team, to ensure individual client requirements and project briefs are met.

How it Works

Rotational Moulding machines are computer controlled, ensuring consistent quality for every unit produced. The Rotational Moulding process is split into 4 operations:
1

1. Charging

The process begins by loading a hollow, aluminium mould with a pre-determined amount of powdered polymer, typically polyethylene and virgin or recyclable material. The mould is then closed, locked and loaded into an oven chamber.
stage-2-heating

2. Heating

Once inside the oven, the mould is rotated biaxially (ie. around 2 axes). The temperature of the oven, typically between 260°C - 370°C depending on the material used, causes the polymer to melt. As the mould rotates, the molten polymer is dispersed evenly and coats the inside walls of the mould.
stage-3-cooling

3. Cooling

After the mould has been rotated sufficiently to spread the molten polymer evenly, it is then removed from the oven and cooled, causing the polymer to solidify.
stag-4-unloading

4. Unloading

When the mould has cooled sufficiently to retain its shape, the mould is opened and the product removed. The mould can then be reloaded and the process repeated.

Benefits of Rotational Moulding

  • Variety of surface finishes and colours
  • Flexible designs
  • Even wall thickness
  • Extremely durable
  • Stronger, lighter mouldings
  • Minimum wastage
