Rotational moulding is a simple process, composed of four basic phases
Rotational moulding is a simple process, composed of four basic phases:
- A pre-weighed amount of powdered or liquid plastic is placed in one half of a thin-walled, hollow aluminum mould, which is mounted on the arm of a rotomoulding machine. The mould is then closed with clamps or bolts.
- The mould is then biaxially rotated on perpendicular axes and moved into an oven where heat is applied. The aluminum mould becomes hot and the powder/liquid tumbling inside rises in temperature. Hot material sticks to the mould in successive layers to form the part.
- When the material has melted and has been consolidated, the mould is moved to a cooling station, where forced air, water mist or a combination of both is used to bring the part temperature down to a point below the crystallization or solidification point of the material. The biaxial rotation continues to prevent the material from sagging.
- Once the part is cool, the mould is moved to an unloading station, where the part is removed. The mould is then ready to begin the process again.
Rotomoulding technology can be applied to numerous sectors:
Lighting, Vases, Furniture, Art, Medical, Kids&More, Sport, Agriculture, Cleaning, Conteiners, Transport, Construction, Urban Design.
