Semi-Fabrication/Semi-Fabricators
Sometimes shortened to ‘semis’,
is the production by rolling or drawing
of gold into alloys
of sheet, tube, wire and other specialist articles for the jewellery or watch-making
trade. This is undertaken by many of the large refiners
whose bars are acceptable good
delivery but in most countries there are also firms which specialize in semi-fabrication.
In Germany, for example, they include Hafner
and Wieland; in Switzerland, Cendres
et Métaux and Précinox;
and in Spain, Sempsa.
