Investering gjutning i rostfritt stål

Investeringsgjutning av rostfritt stål är en industriell process baserad på gjutning av förlorat vax, en av de äldsta kända metallformningsteknikerna. Termen "gjutning av förlorat vax" kan också hänvisa till moderna investeringsgjutningsprocesser.

Water glass and silica sol investment casting are the two primary stainless steel investment casting methods nowadays. The main differences are the surface roughness and cost of casting. Water glass method dewaxes into the high-temperature water, and the ceramic mold is made of water glass quartz sand. Silica sol method dewaxes into the flash fire, and silica sol zircon sand makes the ceramic mold. Silica sol method costs more but has the better surface than the water glass method.

The process of stainless steel investment casting can be used for both small castings of a few ounces and large castings weighing several hundred pounds. It can be more expensive than die casting or sand casting, but per-unit costs decrease with large volumes. Investment casting can produce complicated shapes that would be difficult or impossible with other casting methods. It can also produce products with exceptional surface qualities and low tolerances with minimal surface finishing or machining required.
