Rotational molding (commonly referred to as roto molding) is a productive process that allows for the manufacturing of many different shapes of large, hollow, seamless products (especially plastic). Unlike injection or blow molding - both of which use resin feedstock in the form of pellets (along with heat) - rotational molding uses powdered plastic resin and involves heating the resin while the part is rotated slowly in more than one axis to produce strong, stress-free parts. These parts can be durable, light, and made for individual specifications depending on the needs of partners in each industry.
