Rotational Moulding Heat Cycle
The arm holding the rotational moulds moves in to the oven. The moulds are slowly rotated around three axes this ensures that all surfaces are evenly exposed to the heat source. Gradually the plastic material adheres to the surface of the mould and, over time, builds up a uniform wall thickness. As the mould is slowly rotated the powder is distributed evenly around the inside of the mould. (note: No centrifugal force is used.)
Amber's calculations and experience determines the optimum times and temperatures neccessary for specific materials, wall thicknesses and temperatures. The result is a fully fused shell within the mould with no powders wasted, no voids and no degradation of the material due to over heating.
The arm with it's mould then passes in to the rotational moulding COOLING CYCLE
