also known as rotomolding, is a process most
commonly recognized for its ability to easily
manufacture large hollow parts. A hollow mold is loaded
with a predetermined weight of material, then slowly
rotated while being heated, causing the melting material
to evenly coat the inside surface of the mold. The mold
continues to rotate throughout the heating phase, as
well as the subsequent cooling phase. Finally, a solid
and hollow part is removed from the mold and the process
is repeated again.
We are easily able to mold very strong and durable
parts, in a variety of shapes, sizes, and colors.
Seljan Company can seamlessly take you from an idea to a
finished part. We start with a 3D Solidworks™ model.
After we meet your design expectations our
in-house mold department takes
over. In most cases we are able to get your new tool
ready for production in 4-5 weeks. We have 9 rotomolding
work cells running 24 hours a day. Our largest machine
can mold a part the size of a Smart Car.
Below are just a sample of the over 1200 parts we currently mold for our
