Polyurethane floormats
are an integral part of a Class
8 truck, construction, agricultural
and industrial vehicles cab
environment. These floormats
can be easily color matched
to the vehicles interior and
molded into almost any 3 dimensional
shape.
The material is injected to
the mold as a liquid so the
part thickness can be varied
through out the part. Some of
the benefits of a polyurethane
floormat over a conventional
rubber mat are increased acoustic
and vibration performance for
the operator, part colored to
match other cab interior parts
and improved mechanical properties.
Closed cell foam can be integrally
molded in process into the floormat
to reduce vibration translated
through the mat and act as acoustic
decoupler. The foam is fully
encapsulated on the bottom of
the floormat. |

A Reaction Injection
Molding (RIM) process is used
to manufacture polyurethane
floormats. A filled polyether
Polyol and a MDI are dynamically
mixed together at a specific
ratio. This ratio is PLC controlled
which control flow meters to
precisely dispense the raw materials.
A closed cell foam is placed
on the top (rear) half of the
mold.
The polyurethane is injected
in to the molds under low pressure
and left to cure. Once the parts
are fully cured they are manually
trimmed and left to cure at
room temperature for 24 hours
before packaging. Due to the
low pressure nature of the process
tooling can be manufactured
from polyester resin and wood
making this tooling very economical
for lower volume runs. Typically
this process is used for quantities
between 100 – 10,000 parts
per year. |
