Plastic powder is packed into a mold which is then placed into a high-temperature oven which turns on two axes. The powder melts, leaving a layer of plastic on the inside surface of the mould. The mould is then cooled to allow the plastic to solidify. Finally, the mould is opened to free the perfectly formed piece that has just been produced.

During the manufacture of the piece, a multitude of elements can be included such as: metal threaded inserts, molded threads, openings, graphics, etc.

In addition, almost all finishes can be created with the help of various textures and/or paints. The process also permits the production of complex forms in a variety of material, all the while controlling the thickness of the walls.

The rotational molding process therefore represents an excellent choice because it is flexible and permits the production of plastic pieces without welding, stress and warping. And to top things off, it is very reasonably priced.

See for yourself how the rotational molding process works.
