INVESTMENT POWDER
GOLD STAR BRASSCAST
BrassCast is an exceptionally competitive
Gold Star BrassCast plaster-bonded investment powder, specifically formulated by optimizing the particle-size distribution and thermal expansion to help casters to compete in the most demanding of environments.
The casting of brass for the costume jewellery market accounts for a large percentage of worldwide jewellery production, and is an area where costs must be minimized. Gold Star BrassCast helps achieve this but at the same time produces castings with excellent surfaces, therefore reducing metal loss and keeping finishing work, prior to plating, to an absolute minimum.
Gold Star BrassCast can also, under strictly adhered to conditions, successfully cast silver, producing good quality castings with smooth surface finish.
