Rotomolders are not as common as some other forms of plastic fabricating such as thermoforming, injection molding or blow molding. This is due to the complexity of the process, not the cost as the over cost is often lower than these other forms of plastic manufacturing.

A rotomolder is used to fabricate a number of different plastic products as we mentioned, which means that they are used by a wide range of industries such as the medical, pharmaceutical, marine, sporting goods, packaging, automotive, construction, and so many other industries where near flawless plastic products are coveted.

A rotomolder is made up of a number of components such as cooling chambers, a number of molds, an oven, and the mold spindles which are mounted onto a rotating axis. The process is similar to a number of other plastic manufacturing processes where the plastic resin is inserted into the mold in powder form and then heated in the oven while the mold is rotating.

This allows for an even coat of the mold and then the plastic is hardened within the cooling chamber. Rotomolders are available in a number of different styles and types from the rock and roll to vertical rotational molders, each offers a certain advantage for different applications. Each design has their pros and cons, which is why it is important to find the right rotomolder for your application.

In order to receive the perfect rotomolder for your process and application, it all starts with finding the right rotomolder manufacturer. Relaying your specifications and needs to your manufacturer is the next step, from there the manufacturer should be able to recommend the right style of rotomolder for your specific application.
