Investeringstøbning i rustfrit stål

Stainless Steel Investment Casting is an industrial process based on lost-wax casting, one of the oldest known metal-forming techniques. The term "lost-wax casting" can also refer to modern investment casting processes.

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.

Auwell stainless investment casting, the normal material is 304, 304L, 316, 316L and DSS (Duplex Stainless Steel). Recently, we developed 1.4581 stainless steel investment casting parts for a German client for paper industry. Auwell stainless steel investment casting, the size limits are 3 g (0.1 oz) to several hundred kilograms. The cross-sectional limits are 0.6 mm (0.024 in) to 75 mm (3.0 in).

- Comprehensive Solution Provider

Auwell leverer omfattende tjenester til investeringstøbeprojekter i rustfrit stål, der starter fra design gennem prototyping, værktøjs- / inventarudvikling, prøveudtagning, masseproduktion og til logistisk og post-salg support.

- Rigid QC Policies

Den strengeste kvalitetspolitik starter fra materialekontrol og følges op til den afsluttende inspektion før forsendelse. Til kvalitetskontrol af støbedele leverer vi setof testrapporter inklusive kemiske komponenter, mekanisk egenskab, røntgenprøve, metallografisk analyserapport osv. Til dimensionsinspektion tilbyder vi 3Dscanning rapport, også CMM er tilgængelig til inspektion. Vi strukturerer vores processer, skaber flowdiagrammer og kontrolplaner inden produktion, idet alle QC-processer er i overensstemmelse med ISO9001-2015-krav og tegningsspecifikationer.

- Flexible Payment Term

Værktøjsbetalinger skal forudbetales. Til masseproduktion tilbyder vi fleksible betalingsbetingelser, der gives rimelige kreditbetingelser, kunden betaler kun, når de er tilfredse med det produkt, de har modtaget. For langsigtede projekter tilbyder vi afbrydelsestjenestetjenester for hurtige leveringskrav.
