Or rotomoulding

is a plastic manufacturing process in which polymer powder is evenly distributed along the walls of a mold as it rotates at high temperatures. This process enables the production of hollow, seamless, and durable components such as tanks, crates, containers, agricultural machinery parts, kayaks, enclosures, and more.

How Does It Work?

1. Adding the Raw Material – A precise amount of polymer powder (e.g., HDPE) is placed into a closed mould.
2. Heating and Rotation – The mold rotates around two axes simultaneously, similar to the motion of a swing carousel combined with the rotation of a washing machine drum. This ensures that the molten plastic evenly coats the mold’s interior.
3. Cooling – Once the desired wall thickness is achieved, the mould is cooled, solidifying the material.
4. Removing the Finished Product – After cooling, the final part is removed from the mold and may undergo further processing.

This manufacturing technique produces highly durable products with uniform wall thickness and no internal stresses, making them ideal for applications requiring strength and resistance to damage. 

The success of rotomoulding depends on the design of the product. A well-designed product allows for optimized manufacturing and assembly processes, which in turn ensures the overall success of the product.

At ILLION, we offer rotomoulding of plastics based on the design entrusted to us or made by us to the customer’s order. Upon request, we also develop castings (milling, drilling, cutting) and assemble products composed of multiple elements. 

From product design to mouldmaking, our high-performance moulding processes and multi-axis and CNC machines allow us to tightly control all stages of fulfillment costs.

Our team leaders, responsible for quoting, production scheduling, moulding, and finalization, work together to ensure smooth communication and delivery of the project according to set goals and expectations.

Rotational moulding tools are more cost-effective to produce than other methods and generate very little material waste, making it an inherently economical process.

Furthermore, the raw material utilized in the manufacturing process is rigorously controlled and waste is minimized, with recycling as a standard practice. This makes rotomolding an environmentally responsible process.

Thanks to the use of the latest production techniques, professional software, and 30 years of experience, our production costs are unquestionably competitive and the process is highly cost-effective.
