Question 1

steam bending

Answer 1

hardwoods

The wood is heated in the steam chamber to become more pliable and formed in specific shapes

Question 2

Lamination

Answer 2

Hardwoods

Thin layers of wood are glued together and pressed into a former to form a specific shape

Question 3

press forming

Answer 3

All materials(must be in sheets)

A sheet is pressed between a saddle and a yolk until they harden and this shaped them

Question 8

sand casting

Answer 8

Metals

The metal is melted and poured into a mould made of sand

Question 9

die casting

Answer 9

Non ferrous metals

The metal is melted and poured into a mould made of hardened steel

Question 10

work hardining

Answer 10

Working a non ferrous metal to the point it hardens by hitting and bending it

Question 11
