Type relocating to hamlet (3,5)
I believe the answer is:
hot metal
'type' is the definition.
(hot metal is type used in printing)
'relocating to hamlet' is the wordplay.
'relocating' indicates anagramming the letters (I've seen 'relocated' mean this).
'to'+'hamlet'='tohamlet'
'tohamlet' with letters rearranged gives 'HOT METAL'.
(Other definitions for hot metal that I've seen before include "stolen gold?" , "Typesetting technique" , "Type that got bashed about" .)
