p2-methods of manufacture

Question 1

electrohydraulic forming

Answer 1

sheet metal is forced against a former by a shockwave from an electrical spark in a water tank

ADV- uses one-sided former
-fast, great detail is possible
- material is evenly disrupted

electrical appliance cases, car parts

Question 2

Advanced 3D printing of metals using direct metal laser sintering

Answer 2

a laser fuses metal particles, layer by layer

ADV-complex, strong and lightweight parts can be made
-undercuts and internal voids are possible

-one-off prototypes test parts

Question 3

Fibre injection moulding

Answer 3

injection moulding using pellets of glass or carbon fibre filled polymers

ADV- parts produced are very strong, stiff, lightweight
- facilitates sustainability by reusing carbon-fibre waste

-lightweight parts for aerospace, automotive, sports equipment

Question 4

laser beam welding

Answer 4

intense heat of laser beam is used to join multiple pieces of metal

ADV- narrower, deep welds possible, no finishing needed, welds thin sheets

shipbuilding, construction, railway equipment

Question 5

Physical vapour deposition

Answer 5

base material is vaporised and deposits a thin layer

-abrasion resistance
-durability
-large range of materials
-uniform deposition

-semi-conductor components
- food packaging
