143. What is rotational plastic molding?

Latest plastic molding technology to make their incredible very affordable portable spas that go from the truck to use in mere minutes.

It's called rotational plastic molding and it is the means by which extremely large items can be molded from molten plastic. Up until this technology was developed, larger items had to be made from other types of plastic such as vinyl that had innate shortcomings.

You have seen small durable plastic items such as toys before. These are made by an injection molding process and they are almost indestructible. However; molten plastic is difficult to form, so up until recent years only smaller items could be made with it. That is until rotational custom molds technology was developed.

With this new technology that's used by Roto Spas to create incredibly light and durable, high grade plastic spas, granular plastic is places into the large mold.
