Tool Maker Trainee Interview Questions and Answers

Standard methods for inspecting and testing plastic parts include visual inspection, dimensional measurement, and mechanical testing.

• Visual inspection involves checking for defects such as cracks, warping, or discoloration.

• Dimensional measurement ensures that the part meets specified tolerances using tools like calipers or micrometers.

• Mechanical testing assesses the strength, flexibility, and durability of the plastic part through methods like tensile testing or impact testin...read more

Injection molding, blow molding, and compression molding are three different manufacturing processes used to create plastic parts.

• Injection molding involves injecting molten material into a mold cavity, which then cools and solidifies to form the desired shape.

• Blow molding is used to create hollow objects by inflating a heated plastic tube inside a mold.

• Compression molding involves placing a pre-measured amount of material into a heated mold cavity and then compressing it to ...read more

The material used in die depends on the type of die and the material being worked on.

• Common materials for die include steel, aluminum, and tungsten carbide.

• The material chosen must be able to withstand the pressure and heat of the manufacturing process.

• The material must also be able to resist wear and tear from repeated use.

• Different types of dies may require different materials, such as forging dies made from high-strength steel.

• The material used in die can also affect the q...read more
