Gold Star Powders

Gold Star Powders (GSP), a division of Goodwin Refractory Services Ltd, is part of the Goodwin PLC Group, who have over 125 years of history in moulding and casting metal dating back to 1883.

GSP, with its sister companies, is now the largest manufacturer of Investment Casting Powder in the world, producing over 30,000 tonnes worldwide per year; this equates to 1.5 million sacks (22.7 kg) of investment powders.

Our ability to compete is aided by our economies of scale and the fact that, within our group of companies, we have our own silica deposits, and state-of-the-art calcining facility, to manufacture our own Cristobalite. This vertical integration ensures a secure and competitive supply of the most important and expensive component of investment powder.
