What is the main material used in screen-printing?
Papers and Textiles
Common products include posters, signs, and t-shirts.
What products are made using offset lithography?
Posters, newspapers, plastic bags
This process uses rollers and a plate cylinder.
How does screen-printing apply paint?
Places paint on top of a screen with a stencil
The paint creates the desired shape underneath.
What is a key advantage of screen-printing?
Good for one-off and batch production
Often done by hand.
What materials are used in lathe turning?
Wood and metal
Common products include chair legs and baseball bats.
What is the primary process in lathe turning?
Material is spun at high speed and cut to shape
Can be done by hand or automated machinery.
What is die casting primarily used for?
Car parts, engine components
Involves pouring molten metal into a reusable mould.
What is a defining characteristic of die casting?
The mould is reusable
Unlike sand casting.
What is the primary material used in injection moulding?
Plastics
This process produces items like chairs and toys.
Describe the injection moulding process.
Plastic granules are heated and forced into a mould
Produces hundreds of identical products at once.
What is the main product of blow moulding?
Plastic bottles
The process involves heating a plastic parison.
How does blow moulding shape the plastic?
A parison is filled with air to fit the mould
The shaped plastic is then cooled and released.
What is a key advantage of injection moulding?
Great for mass production
Makes hundreds of products at once.
What are the materials used in offset lithography?
Papers and card (thin, flexible plastics)
Utilizes rollers containing colours and water.
Fill in the blank: In die casting, molten metal is forced through a _______ into the mould.
nozzle
This allows for precise shaping of components.
True or False: Blow moulding is suitable for producing items other than plastic bottles.
False
It is specifically designed for bottles.
What is the primary advantage of using offset lithography for production?
Can be used at batch and mass production
Effective for large print runs.
What is the function of the water in the offset lithography process?
Stops colours from sticking to certain places
This helps create the desired shape.
