Rotational Molding, also called rotomolding or rotocast, is a thermoplastic process for producing hollow parts by placing powder or liquid resin into a hollow mold and then rotating that tool bi-axially in an oven until the resin melts and coats the inside of the mold cavity. Next the tool is cooled and the part is removed from the mold.

     Four steps in manufacturing a rotational molded part
    
    
    1. Fill the mold with a polymer material
    
    
    2. Heat tool in oven to melt material
    
    
    3. Cool tool to solidifies the part
    
    
    4. Remove part from the tools
    
    
    
    Design & Manufacturing
    Rotational molded parts can be made out several different kinds of materials and have multi-layered walls. Unusual shapes can be produced as one part, that normally would have to be assembled from several parts.
    Rotomolding was actually invented in the 20th century, but didn't gain traction as a production process until the 1960s. Today, it continues to advance as a viable process for plastic part creation.
