How a Hot Tub is Made
A new rotationally molded hot tub's construction is
a skilled process, that is carefully monitored at every stage by experienced
hot tub engineers. The next few pages will give you an insight into how
a rotationally molded hot tub is made.
The Polymer Plastic
A new hot tub will start life as a small heap of polyethylene plastic
granules which will eventually be turned into a fully functional hot
tub. Polyethylene granules are used so that the new hot tub will not
rot, rust or crack this give it an advantage over traditionally constructed
Hot tubs. The polyethylene granules are a chemically complex material
which has been carefully produced by chemical engineers to ensure the
new hot tub is as strong and resistant to the elements as physically
possible. They are both UV and Chemically resistant.
The first stage of the production process for the plastics
engineer is to mix the polymer compounds to just the right colour for
the new hot tub. This will be a carefully measured process using a
number of different compounds as to produce an attractive and uniform
finish. Once the mix of the Polyethylene compound is complete a measured
amount will be poured into a cast aluminum mold and sealed using clamps
around the rim of the mould.
