| Same old stuff. In
injection moulding for complicated solid shapes. Injection blow moulding
for complicated hollow shapes. Extrusion for rope and stuff (shapes
which are the same all the way down their length). Good stuff is plastic
in many ways. Easily cleaned, resists weather well. Does not need a
coating of anything (like paint). Comes in all colours. Can be recycled.
Look at the links above to see plastic moulding processes. This one
looks like it is fixed together with joints which slot into each other
(look at the corner nearest to you). |
