Brass investment casting parts

The steps are repeated until the investment reaches its required thickness-usually 5 to 15 mm (0.2 to 0.6 in). Investment moulds are left to dry completely, which can take 16 to 48 hours. Drying can be accelerated by applying a vacuum or minimizing environmental humidity. Investment moulds can also be created by placing the pattern clusters into a flask and then pouring liquid investment material from above. The flask is then vibrated to allow entrapped air to escape and help the investment material fill any small voids.Common refractory materials used to create the investments are: silica, zircon, various aluminium silicates, and alumina.
