manufacturing techniques.
forging
bending
moulding
casting
sheet metals
can be done with a sheet metal folder
can be done with a bending jig
iron and steel are forged,
the metal is heated up until it is malleable.
the metal is then hammered into shape.
wood
lamination
thin pieces of material are glued together.
after wood is laminated it is put in a jig until it dries in the correct shape.
plastic
plastic is bent using heat
can be done with a strip heater.
can be done with an oven
pressure die casting
pressure is applied to the the liquid to be forced into the die.
gravity die casting.
liquid is pored in under the pressure of gravity
more intricate/detailed parts.
poring a liquid into a mould and waiting until the liquid sets and becomes a solid.
injection moulding
uses pressure to mould plastics
blow moulding
uses air to blow plastic into a the shape of a mould
