The invention discloses a rotational moulding preparation process of an air mover shell. The rotational moulding preparation process comprises the following steps: S1,
raw material particles are ground, and
raw material powder is obtained; S2, the
raw material powder, color
powder and waste with the same color are all stirred, and mixed powder is obtained; S3, the mixed powder is weighed and poured into a designated lower mould; S4, the mould is placed on a rotating frame, and the rotating frame is conveyed into an oven; S5, the mould is heated, meanwhile, the rotating frame drives the mould to rotate, and the mould also rotates along the axis of the mould; S6, after the mould is baked in the oven for 1300 s, the rotating frame is conveyed out from the oven; S7, the outer surface of the mould is rapidly cooled through a
coolant; and S8, the mould is opened, and a product is taken out from the mould. After baking in the oven is completed, the mould is rapidly cooled through the
coolant,thus the mould is shrunk, but the product is still in an expansion state, thus the mould and the product generate
relative displacement and then are easy to separate, and burrs are not prone to beinggenerated.
