Question 1

Give the name of the machine that performs the stamping operation.

Accepted Answer

The answer of Give the name of the machine that...

Question 2

Name the common fabrication process for thermosets that uses a specific amount of material that is heated and placed in a closed mold where additional heat and pressure are ap- plied until the material takes the desired shape. The mate- rial is then cured and removed from the mold.

Accepted Answer

The answer of Name the common fabrication process for thermosets...

Question 3

Name the manufacturing process that is the most commonly used process for creating thermoplastic products. The pro- cess involves injecting molten plastic material into a mold that is in the form of the desired part or product. The mold is in two parts that are pressed together during the molding process. The mold is then allowed to cool so the plastic can solidify. When the plastic has cooled and solidified, the press is opened and the part is removed from the mold.
