What is rotational molding, and why is it an advantage for hot tubs? It is the process where powdered plastic is heated, gelled, and ultimately "spun" on two axis to assume the shape of whatever you wish.
This high tech process affords incredible functionality and flexibility. Virtually any shape can be created in conformance with required tolerances and specifications. The natural G forces of rotational molding ensure that the plastic spreads uniformly throughout the mold until it is allowed to cool and harden thus guaranteeing structural consistency and integrity.
At the same time, the performance characteristics of the plastic compound(s) used in this process inherently maintain incredible beauty and durability against impact abrasion, and elements. As applied under the rigorous demands of playground equipment to medical waste disposal containers, these plastic products look and perform well for years.
Besides being functional, this process provides the benefit of being flexible. Shapes and colors are limited only by the creativity and interests of the people who design and ultimately use the products. This is a new possibility within the hot tub industry, where current vacuum forming processes have inherent color, shape, and response time limitations.
