What is a sectional view and how does it help. What it is: How it works: Why it works: When it is used:
What it is: It is a 3D CAD or physical model that can be cut int sections to allow the designer and manufacturer to see the interior.
How it works: It enables the designer or the manufacturer to see the interior of a product with joining methods and support areas.
Why it works: It simplifies how the manufacturer can produce a product and how the designer can see inside a product.
When it is used: It is used in manufacturing and the design process, it is used when the interior of a product is extremity complex as it allows them to see the inside.
What is the definition of CAD and what is it used for
CAD (Computer-aide design) a piece of software that is used to assist designers with designing products from phones to houses, roads, and packaging. It allows them to make more accurate designs with more accurate information and can be used to assist in the manufacturing process. Some machines can use the designs to make the product automatically which makes it more accurate, low cost and time saving
How is steel galvanised and why
it is cleaned and then dipped in a zinc bath that coats all the steel and then it is left to harden.
It is galvanised to protect it from weathering and corrosion so it does not rust or break.
What is injection moulding
Injection moulding is when liquid plastic is injected into a mould and then set in a shape.
What is blow moulding
blow moulding is when liquid plastic is blown into a mould like a bubble.
what is rotational moulding
rotation moulding is when liquid plastic is injected into a mould and then the mould rotates until the entire interior is covered in plastic and it rapidly cooled so it sets covering the mould.
How are products powder coated
2 electrodes are attached to the product and a charge is put on the product, this creates an electrostatic field that attracts certain materials and this allows a powder form of metallic paint to be sprayed onto the product and once bakes it stays on the product creating a new finish with a nice colour and texture.
Name 3 welding processes
MIG (Metal Inert Gas) Welding
Arc Welding
TIG (Tungsten Inert Gas)
FCAW (Flux-Cored Arc Welding)
What is MIG welding
MIG welding is combining two pieces of metal together with a wire that is connected to an electrode current.
What is TIG welding
TIG welding uses an electrode that heats the base metal to create a molten weld puddle. By melting two pieces of metal together, this uses fewer materials and creates a strong joint.
What is ARC welding
ARC welding uses an electric current to form an electric arc between the stick and the metals to be joined.
What is FCAW Welding
FCAW Is a slightly easier form of MIG welding except it uses a special type of wire to join materials together and it does not require an arc joint and can be used to create a stronger joint.
What is a composite metal
A metal composite is at least two components, one being a metal, the other material may be a different metal or another material, such as a ceramic or organic compound.
What is a hybrid composite?
It is the same as a composite material but it has at least three materials are present.
List three different types of smart materials
shape memory alloy Thermochromic materials Photochromic materials Piezoelectric materials Quantum-tunnelling composite Electroluminescent materials
What is a shape memory alloy
metals that remember previous shapes
What is a Thermochromic material
changes shape or colour in different temperatures
What is a Photochromic material
changes colour in different lights
What is a Piezoelectric material
produces a small electrical charge
What is a Quantum-tunnelling composite
a flexible composite that contains metal particles
What is an Electroluminescent material
produces light when an electrical charge is produced
