Rotational Molding (Roto Molding)
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.

Mold Design and Manufacturing (Tooling)
Speed Up Your Product Development Process by Eliminating Non-Value Added Steps:
Sister company to Rhino and located on the same premise, American Roto Tool (ART) prides itself on turning around projects quickly while getting it right the first time. By eliminating the model and casting phase (Cast Molding) , ART can move directly into Milling your tool utilizing one of five state-of-the-art CNC Milling Machines. This means acceleratiion of your project from CAD designs directly to production molds within days or weeks (dependant on the size and complexity of the mold). The CNC Milling process also allows for far better detail on the interior finish, laser accurate parting lines and superior part tolerances. Bottom line, a much better mold in far less time.
Extended Mold Life and Competitive Pricing:
We begin with virgin aluminum and shape the mold directly into the block. In other processes (Cast Molding), the metal is melted down (again) leaving the aluminum (and ultimately the mold) far more susceptible to material contamination, voids and porosity. These three issues directly affect the quality of the part and longevity of the tool. With American Roto Tool’s CNC Milling and Tool Fabrication processes, you maximize your investment by extending the life of the mold while minimizing costly re-builds and repairs that go hand in hand with other processes.
With our process of eliminating unneeded and labor intensive steps from your project, American Roto Tool remains competitive and ultimately more affordable than other tooling methods.
