Benefits of Rotational Molding

Rotational molding services have several advantages over other forming services. First, molders are able to change colored plastics without extensive line cleanings or die purgings, which saves on time and added costs. Second, rotational molding does not require pressure, which helps to limit tooling costs as well as energy-related costs. Equipment costs are also low because the cast or welded molds they use are significantly less expensive than other kinds. Plus, most of the excess material created during this process can be recycled; this is not only economical, but environmentally friendly too.

In addition, rotomolding’s even and seamless coating of style produces strong outside corners with virtually no stresses. This seamless coating is especially advantageous to those making pressure vessels and tanks, as any little seam or crack can lead to pressure vessels bursting. Finally, using this method, a product or prefinished mold part can be assembled inside a single mold. Unlike alternative methods, which involve tooling of a new die even for small changes, rotomolding provides great flexibility. Due to this flexibility, the design time can once again be cut down significantly.
