Question

Extruder die is a machine part that gives final shape to the polymer material used in the extrusion process.

(a) True

(b) False

I had been asked this question by my college director while I was bunking the class.

My question is based upon Extrusion in Polymers topic in division Moulding with Polymers of Casting-Forming-Welding II

Answer 1

Right answer is (a) True

To explain: Extruder die is a machine part that gives final shape to the polymer material in the extrusion process. It produces a channel through which liquid polymer exit the extruder by applying pressure that increases in the barrel during the process. The liquid polymer comes out from the die with a constant speed, that’s why the design of die is very important for specification and accuracy.
