ABSTRAK :
One of the goals of the technology creation is to make easier for
humans to fulfill various life needs. It can be felt and proven by the increasingly
demanding of all human needs that are all easy, modern and practice. Making
objects, equipment and equipment for human life needs with plastic raw materials
is one example of the application of science and technology. The plastic process
uses using a vacuum forming method, the results of the vacuum forming method
itself will be used as a replacement for airfoils in the aerodynamics laboratory of
STT Adisutjipto because the airfoil cannot be reused.
The method used in this discussion is the vacuum forming method. Vacuum
forming is the process of forming plastic sheets by first heating the plastic sheet and
then forming a plastic sheet by vacuuming into the mold according to the product
you want to produce. Therefore it is necessary to do a test by varying the
temperature at heating the material to know the good soft point. So that the shape
produced is in accordance with the mold.
The results obtained are the formability of plastic material when heating
with temperatures of 150ºC and 175ºC. The plastic does not experience sufficient
expansion because the plastic is still rigid or not yet flexible as seen from the length
of the widening of the mold which is 14 mm for temperatures of 150 ℃ and 10 mm
for 175 ℃. Whereas formability at a temperature of 200 ºC plastic has a good
expansion, the plastic can follow the mold well, but there are still cavities on the
sides of the mold length of the mold that is 7 mm.
