Vacuumformed parts are made by heating pre-extruded rigid plastic sheets
and forming over or into a mold, applying vacuum to suck the hot sheet to the
contour of the mold.
The first step is to setup the machine; mounting the mold, adjusting the rails
for the sheets, setting the computer parameters, pre-heating the oven.
The operator than loads the pre-extruded plastic sheet and starts the machine
cycle. The machine heats up the sheet for a few seconds up to several minutes,
depending on material and thickness. Than the machine pulls the hot sheet
over or into the mold, and sucks it to the mold surface by means of vacuum.
Now the cooling process starts which takes several minutes. After cooling the
operator takes the formed part out, reloads the machine, and inspects the part.
Secondary operations include trimming off excess material, deburring,
cleaning and packing. Drilling, milling, riveting, glueing may be added as
needed.
Finally the product goes through final inspection, packing and shipping.
