Thermoplastic molding process
WebbThe plastic is blown into a mold and as it expands, it presses against the walls of the mold taking its shape. After the plastic “balloon” fills the mold, it is cooled and hardened, and … WebbRotational molding (also called rotomolding) is a process that involves heating a hollow mold filled with powdered thermoplastic and rotated around two axes to produce mainly large hollow objects. Processes for rotomolding thermoset plastics are available as well, however less common.
