What is Rotomolding?
Rotomolding, or rotational molding, is a manufacturing process to create hollow plastic products. It involves heating a mold and adding powdered plastic resin, typically polyethylene, which melts and coats the inner surface as the mold rotates in multiple axes. After solidification through cooling, the mold is opened, and the finished product is trimmed and removed.
This technique produces small to large, seamless, intricate plastic items with consistent wall thickness. Rotomolded products find applications in various industries.
What is Thermoforming?
Thermoforming is a manufacturing process that involves heating a thermoplastic sheet until it is pliable and then forming it over a mold to make a small part or a large product that can accommodate secondary finishes like inserts, handles, holes, etc. The resulting part can be of varying sizes, shapes, and thicknesses, making it ideal for a wide range of applications.

How long does it take to make a mold for rotomolding? For thermoforming?
The timeline for mold making is completely dependent on the simplicity or complexity of your part. Sometimes, molds for either process can be built in as little as four weeks. Be aware, though, that the larger the size and more complex the shape, the longer it will take. Our team will be your partner at every step of the mold-making process, learn more here.
How can I tell if rotational molding or thermoforming would be best for my product?
- Rotomolding can be the best solution when the part needs uniform thickness or strong corners.
- Thermoforming might be best for longer runs and crisp details on both sides of the part.
As our engineers develop increasingly sophisticated processes for both roto and thermo, it’s often hard to say which process will be best until they review your specs. Let us find the best method to make your part or product efficiently, quickly, perfectly, more durable, more attractive, more lightweight, at a lower cost; you name it.
