What is Rotomoulding?
Rotomoulding is a process applied to plastics, usually polyethylene, by means of which it is possible to manufacture hollow objects in a wide array of sizes, shapes, and textures.
In this first stage, the mould is opened, filled with powder plastic material, and closed.
This causes the plastic material to become attached to the internal walls of the mould, obtaining a hollow or semi-hollow part.
This stage is what causes the plastic to maintain the desired shape while it solidifies, to enable its demoulding.
On the other hand, the wall thickness can be uniform. However, rotomoulding offers the option of modifying this characteristic in certain areas, so it would be possible to make this change without modifying the mould.
This technique is perfect for short runs as the process enables a short run of parts to be produced. In addition, the material is added at the beginning of each cycle, so different colours can be serially produced without stopping production.
They are integrated into the mould, prior to the heating stage, and they are fully embedded in the part at the end of the process. Wheels, watches, plugs, gauges, etc.
It is also worth noting that the parts manufactured are hollow or semi-hollow. Thus, no welding is required and there is no material waste.
Finally, with the latest improvements in technology, it is possible to mould high-quality graphics into the part. They remain unaltered as they are moulded within the part and have great resistance to impact, scratches, and wear.
