Gemcast™

SPECIAL APPLICATION POWDER FOR STONE-IN-PLACE CASTING OR WAX SETTING

Gemcast can be relied on for highly effective solutions for stone-in-place castings because it is Whipmix who pioneered the inclusion of special additives into investment powder for this kind of application.

Whipmix Gemcast is simple to use and is mixed in the normal way for standard Gold and silver investments. All that needs to be adjusted is the burnout cycle temperature which must not exceed 630°C.

Today, Whipmix Gemcast is the industry leader for wax setting investment powders. It works by ensuring that the correct de-oxidising additives are present, thereby minimising the risk of damage to diamonds or other precious stones. These include problems with burnt diamonds, accelerated set times, incomplete filling, spalling and flashing over or under stones.

Prima-Cast is packed and available as follows:

• 45 kilo Fibre Drum, 24 per pallet;
• 45 kilo Polypropylene Sack, 25 per pallet;
• 22.5 kilo Polypropylene Sack, 50 per pallet.
