Moulding Process
Rotational moulding is a three-stage, no-pressure, plastic moulding process.
During the heating stage, the mould slowly rotates in two planes (bi-axial rotation). Heat transfer causes the plastic charge inside the mould to melt and uniformly coat the interior of the mould.
During the second stage, the mould moves to the cooling station where it is cooled by air and/or water spray.
In the final load/unload stage, the part is removed from the mould and a new charge of material is loaded into the mould.
