Understanding Compression Moulding

What type of plastic is used in compression moulding?

• PVC

• Thermoset plastic

• Polyethylene

• Polypropylene

How is the plastic shaped in compression moulding?

• By forcing it into a mold shape

• By extrusion

• By layering

• By spinning

What happens to the material in the mold in compression moulding?

• It expands

• It dissolves

• It cools down

• It sets hard

Which of the following items is NOT typically made using compression moulding?

• Toilet seats

• Computer chips

• Saucepan handles

• Wall sockets

What is a limitation of compression moulding?

• Long production time

• Simple moulds only

• Complex designs

• High cost

How can you identify a product made by compression moulding?

• It is very complex

• It has no split lines

• It is simple and heat resistant

• It is made of metal

What is a characteristic of the compression moulding process?

• Highly accurate process

• High material wastage

• Use of multiple materials

• Inaccurate material calculation

What might still be visible on a product made by compression moulding?

• Color variations

• Split lines

• Stickers

• Holes

Why are the moulds in compression moulding kept simple?

• To reduce cost

• To allow for complex designs

• Due to the limitations of the process

• To speed up production

What is not a feature of compression moulding?

• Mass production capability

• Complexity of processes

• Excess material

• Simple product designs
