Production details
Rotational moulding is a simple process. The first step is to produce a hollow metal mould called a tool, the tooling cost and complexity required for this process is significantly lower than that of injection moulding or blow moulding. The tools can be made from cast aluminium, fabricated steel, CNC block aluminium or CNC steel, depending on the requirements of the product. The tool is filled with a measured amount of plastic powder or pellets, called the shot weight. We use a wide range of materials, such as thermoplastics, polythethylene, polypropylene, polyvinyl chloride, nylon / polyamides and foamed polymers / plastimers.
The two sections of the tool are closed up and it is moved on a mechanical arm into one of our ovens, which can be heated as high as 360º Celsius. The arm is continuously rotated in the oven, about 10 times per minutes, around both the horizontal and vertical axis. When complete the piece will be cooled and de-moulded. This innovative process allows for a multitude of solutions to be created, with finishes which can make plastic products waterproof, weatherproof and increase durability.
