Aluminum rotational molding spiral slide mold
The biggest advantage of the rotational molding method is that the mold is simple and the cost is low. It is used most to produce large hollow products, but correspondingly requires larger production equipment and well-designed molds.
Plastic raw material (typically in powder form) is placed inside a mold (cast aluminum, CNC machined aluminum)
The mold is attached to an arm of a rotational molding machine, and enters the oven where it rotates (rotational molding) on two axes.
As the plastic material melts, it begins to adhere to the inside mold walls, building wall thickness and taking on the shape and texture of the interior mold surface.
After rotating in the oven, the mold enters the cooling phase, where the molten material eventually solidifies into the finished, hollow plastic part.
The part is then removed from the mold, where it undergoes a variety of secondary operations (trimming, foam-filling, assembly, etc.) prior to shipment.
Advantage of Rotational molding mould
The cost of rotational mould is relatively low which is only about 1/3-1/4 of blow mold tools or injection mould at the same specification and dimension.
The shape of rotational mould could be much more complex. The edge strength of rotational mould is much better. Rotational moulding products can be produced fully closed.
Compared with injection mould, the advantage of rotational mould product is hollow, weldless, higher strength and with complex surface configuration.
