The basic processing process of rotational molding is quite simple; it involves placing powdered or liquid polymer into a mold, heating it while rotating around two perpendicular axes (spinning and orbiting).

Applying Release Agents: Applying release agents to molds facilitates the removal of products from the molds and effectively prevents damage to the products during demolding due to strong adhesion between the product and the mold.

Install inserts and related forming accessories: Inserts primarily serve to reinforce specific areas of the workpiece, while forming accessories mainly refer to modules used for forming grooves or special sections; they must be properly installed in the designated positions before material is added to the mold.

Before adding materials, strict measurement should be taken. When additives are needed, the relevant components should be pre-mixed. Accurately weigh the required amount of powder resin and place it at the bottom of the split mold. Then, securely fasten the two halves of the mold together and mount it onto the bearing shaft.

Ensure that any leftover material at the clamping area is removed before closing the mold to ensure the two halves fit perfectly, preventing material leakage during the processing.

Heating: Place the mold filled with materials into a heating furnace (or heat with gas flames or other heat sources), setting the furnace temperature above the resin melting point. The frame rotates simultaneously around the main and auxiliary axes, which are perpendicular to each other, performing both clockwise and counterclockwise rotations. During rotation, the mold is heated to the specified temperature and then held at that temperature. The material gradually melts under rotation and heat, settling on the entire inner wall of the mold cavity and gradually expelling the gases trapped within the material until a well-formed product is formed.

Cooling and Setting: Once the resin is fully melted, transfer the mold to the cooling chamber, where it is cooled while continuously rotating and being cooled through forced ventilation or water spray.

Demolding and mold cleaning: The former must prevent damage to the product during demolding, while the latter involves thoroughly removing any residual material and debris from the mold to prepare for the next molding cycle.
