Question 3

A heated press uses a metal die to stamp a pattern into plastic. During use, the die reaches 250 °C.

The die is suitable only if:

  • it remains solid at 250 °C
  • the permanent indentation made in a test is no more than 0.50 mm deep.

Two samples are tested at room temperature using the same force. One sample is a transition metal and the other is a Group 1 metal.
