First, fix the rotomolding mold to the appropriate position on the mold base and adjust the balance of the mold base.
Second, the rotation speeds of the primary and secondary shafts are kept balanced and the speed is uniform.
Third, the furnace ensures uniform heating of the mold in all directions.
Fourth, the heating and cooling processes are all reversed once, and the commutation should be rapid. Generally, the forward and reverse times are the same.
Fifth, in the part where the thickness of the product is required to be increased, the corresponding part of the mold is required to be preheated or to reduce the influence of the heat insulating factor.
Finally, in the part where the thickness of the product is required to be reduced, the corresponding part of the mold is insulated with a tetrafluoroethylene sheet or an asbestos pad, so that the molten material is not easily attached to the mold or continuously stacked to reduce the thickness of the portion. This method is also used to lining the insulating layer on the mold so that the inner surface of the mold cannot adhere to the resin to obtain the opening portion, but the opening made by this method is generally not regular.
