1.A predetermined amount of polymer powder is loaded into the cavity of a split mold
2.The mold is then heated and simultaneously rotated on two perpendicular axes, so that the powder impinges on all internal surfaces of the mold, gradually forming a fused layer of uniform thickness.
3.While still rotating, the mold is cooled so that the plastic skin solidifies.
4.The mold is opened, and the part is
unloaded Rotational speeds used in the process are relatively slow It is gravity,not centrifugal force, that causes uniform coating of the mold surfaces
