What is the maximum thickness that can be allowed for a plastics sheet

1.	What is the maximum thickness that can be allowed for a plastics sheet in a vacuum forming process?(a) 3 mm(b) 3.1 mm(c) 3.2 mm(d) 3.3 mmThis question was posed to me by my college director while I was bunking the class.The question is from Blow Moulding and Thermoforming in section Moulding with Polymers of Casting-Forming-Welding II
Answer» Right choice is (c) 3.2 mm The best explanation: Vacuum forming process is ONE of the important PROCESSES that are employed in thermoforming processes. The maximum thickness of the PLASTIC sheet has to be NOTED, as a clamp is to be fitted around the plastic sheet. The maximum allowable thickness of this plastic sheet is 3.2mm.
