Rotomolding, also known as rotational molding or rotational casting, is a hollow molding method for thermoplastic plastics.
It involves injecting powder or paste materials into the mold. With the heating of the mold and its longitudinal and transverse rolling rotation, the materials are evenly distributed throughout the inner cavity of the mold under the action of gravity and centrifugal force and melt.
Finally, after cooling and demolding, hollow products are obtained. This process has occupied an important position in the plastic processing industry due to its unique advantages and broad application prospects.
