Bego Wirofine Investment is an investment material used in dental laboratories for casting procedures. It forms a mold around wax patterns, which is then heated to eliminate the wax, creating a cavity for molten metal or ceramic to be cast into, fabricating dental prostheses.
This investment material is supplied in a bulk format of 45 individual 400g units. This packaging is suitable for dental laboratories with consistent casting volume, ensuring a ready supply of material for various prosthetic fabrication requirements.

About chrome investment
Chrome investment is the investment sold for cobalt-chromium partial denture frameworks. The use of higher melting alloys has increased the use of phosphate-bonded investment.
A dental casting investment is a material consisting principally of an allotrope of silica and a bonding agent. The bonding substance may be gypsum, for lower casting temperatures, or phosphates and silica, for higher casting temperatures. In the lost-wax technique a wax pattern is surrounded with a refractory slurry that sets, the pattern is removed by heat, and metal or ceramic is cast into the mold that is left.
ISO 15912 covers casting investment, brazing investment, pressable-ceramic investment and refractory die materials, and classifies them by intended use and by the burn-out procedure the manufacturer recommends.
How the investments and duplicating materials on this shelf differ
- Universal Investment — Phosphate-bonded powder and its mixing liquid, sold for more than one kind of casting.
- Chrome Investment — For partial denture frameworks cast in a higher melting alloy.
- Pressable Ceramic Investment — The mold material for pressed ceramics, not for cast metal.
- Refractory Investment — Material for casts, dies and pegs that must go through the furnace.
- Duplicating Materials & Flasks — Gels, silicones and flasks for copying the master model in investment.
- Duplicating & Die Silicone — A silicone that makes the flexible mould of the master model.
What to look at when choosing an investment
Binder and temperature: gypsum is not chemically stable above 650 °C, so gypsum-bonded investments are typically restricted to castings of conventional gold alloys.
Expansion: high setting expansion has been reported for phosphate-bonded materials, more when they are mixed with a silica sol, the special liquid, than with water. Setting expansion was found to be sensitive to mixing speed and to the liquid to powder ratio.
Strength: investments are brittle and may fracture at clamping points.
Burn-out: ISO 15912 classifies investments by intended use and by the burn-out procedure the manufacturer recommends.
