Rotation moulded low density polyethylene (LDPE) surface. The embossed logo is cut into the surface of the mould and so reproduced directly into the part. The texture is created by shot blasting (steel bead) on the surface of the aluminium tool. The texture is adjusted by changing the size of steel bead and air pressure used in the process. The glossiness (and subsequently the colour saturation) is determined by the flaming process, which is carried out on the moulded part. Each one is processed separately by heating the surface with an exposed flame. It is often a manual process and so open to variation.
