Rotational Molding is a manufacturing process that creates low stress, hollow parts. This process is ideal for plastic parts with low to medium run quantities (50 to 5,000+ depending on size) due to the relatively low tooling costs when compared to other methods. Rotational molded parts are noted for their strength and consistent wall thickness.
Rotational Molding is a plastic forming method that converts plastic resin into a hollow mass through high temperature rotation which coats the interior of a mold (tool) to the desired exterior form. This is why the process is called “rotational molding” – the mold (tool) rotates on all axes throughout the entire heating process and continues through the rotation until cooled.
Unlike other plastic molding processes (such as Thermal, Injection or Blow Molding), Roto-Molding results in a much more durable and flexible product with seamless and consistent wall thickness. This molding process also distributes more material to corners and edges than other molding methods to help absorb shock and stress where they occur most. Since the material isn’t stressed during the roto-molding process, the finished product is stronger, more flexible and less susceptible to cracking.
Rotational Mold Tooling is much more cost effective for low to medium run parts, as well as large format parts, than other molding methods.
