Make sheets of metal in a cast (8)
I believe the answer is:
laminate
'make sheets' is the definition.
'laminate' can be an answer for 'make' (laminating is a kind of making). I'm unsure of the 'sheets' bit.
'metal in a cast' is the wordplay.
'cast' is an anagram indicator (letters are dispersed or cast around).
'metal'+'in'+'a'='metalina'
'metalina' anagrammed gives 'LAMINATE'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for laminate that I've seen before include "Split into layers; cover with protective material" , "Material constructed in layers" , "Manufacture by layering" , "Anti-male (anag.)" , "Sheet of material made by bonding two or more sheets" .)
