Machine Covers of Structural Foam
Machine covers for data processing equipment can be made from a plasti
material, such as polycarbonate structural foam.
Machine covers are designed with appearance in mind. However, other
points should also be considered. By changing the covers from sheet metal to
polycarbonate structural foam, several technical advantages are accomplished.
First, the aesthetic appearance is improved because flowing lines are possible in
a mold, and a great deal of detail can be included at a low cost. The mold also
gives a textured finish without further operations. Secondly, a lighter frame
construction is practical because less weight is required for the same rigidity in
the covers. This results in lower frame and transportation costs. Third, a better
sound deadening characteristic is achieved from the cellular construction of the
foam. Fourth, a safety quality above sheet metal results since the chance of
electrical shock is reduced.
Polycarbonate structural foam parts are made by injecting polycarbonate with
a foaming agent through an injection press into a mold. The average cycle time
for this process is approximately two minutes, considerably less than the time
required to make the same part from sheet metal.
