1.	Thermoforming process involves injecting of molten plastic into a mould cavity by application of compressed air.(a) True(b) FalseThis question was posed to me in unit test.This interesting question is from Blow Moulding and Thermoforming in division Moulding with Polymers of Casting-Forming-Welding II
Answer» Correct choice is (B) False The best explanation: In thermoforming process, a sheet of plastic is used which covers the shape of any DIE by HEATING it to the desired temperature and then it is stretched over the die using vacuum, thus it is also CALLED as vacuum forming. Then the pressure is applied to the plastic sheet by using pressurized air.
