 OUR
ROTO MOLDING PLANTS MAKE THE SHOPPING KARTS THAT YOU SEE
IN THE STORES THAT LOOK LIKE LITTLE CARS THE KIDS RIDE
IN. THE MATERIAL IS THE SAME AS THE TRAILER BODY. |

 THE
PULMOR, PICTURED AT THE LEFT, AND EZ TOW AND The
Yuppie Wagon shell is roto-molded and then sent
to one of MANY OF THE TRAILER FRAME
manufacturers in the lower 48 states. They
manufacture the trailer, put the PULMOR, EZ TOW
OR Yuppie shell on
it, and then seND it to their distribution
network. since 1996, the company has been one of
the few companies in the world to house a Roto-Molding
machine. Rotational molding produces plastic
parts in a variety of shapes, sizes, and colors
that other processes do not have the flexibility
to produce. |

 The
ROTO molding
process
WATCH 2 MINUTE MOVIE CLICK HEREThe rotational molding process starts with a mold that is placed in a molding machine that has a loading, heating, and cooling area. Pre-measured plastic resin is loaded into each mold, and then the molds go into the oven, where they are slowly rotated on both the vertical and horizontal axis. The melting resin sticks to the hot mold and coats every surface evenly. The mold continues to rotate during the cooling cycle, ensuring an even-wall thickness. Once the parts are cooled, they are released from the mold. The rotational speed, heating, and cooling times are all controlled throughout the molding process. the Association of Rotational Molders International, says that rotational molding offers design advantages over other molding processes because parts that are assembled from several pieces can be molded as one part, eliminating expensive fabrication costs. There is consistent wall thickness and strong outside corners that are virtually stress free, and if additional strength is required, reinforcing ribs can be designed into the part.
Compared to injection and blow molding,
rotational molding can easily produce large and
small parts in a cost-effective manner. Tooling
is less expensive because there's no internal
core to manufacture, which also means minor
changes can easily be made to an existing mold.
And because parts are formed with heat and
rotation, rather than pressure, molds don't need
to be engineered to withstand the high pressure
of injection molding.
