The rotational Molding process lends itself best to hollow containers
and has stages. First a metered amount of powdered resin is
introduced into the bottom half of the mold.The halves are
then sealed together and the mold is placed into a oven to
be rotated on a dual 90 degrees opposed axis. The resin pool
remains in the bottom of the mold and as the mold reaches
a predetermined temperature particles of resin begin to adhere
to the walls. Each time the mold passes under the resin pool
additional resin is added until there is no more resin pool
and the desired wall thickness has been achieved. Run time
depends on temperature and the required wall thickness. After
the mold is removed from the oven and cooled it is opened
and the part extracted. New resin is then introduced and the
process is repeated.
We stock most standard colors for dry blending
and color matches are available. Unlike most processes, ours
also make colors combinations, such as the commonly used granite.
Other special looks are also achievable including your own
unique color compositions. Our colors are consistent throughout
the product. |
