China Silica Sol Investment Casting Factory

Silica Sol Investment Castingis a form of investment casting. The process is very similar except that the investment mould is made from silica sol zircon sand mixed with refractory powder. Silica sol zircon sand is exceptionally fine-grained (10-20 Microns) and can be mixed to a slurry with very low viscosity when creating the mould. The result is a casting method that delivers dimensionally accurate castings with excellent as-cast surface finishes. Crucially, the silica sol zircon mould can withstand temperatures up to 2000°C, making them very useful when casting high temperature alloy steels and stainless steels.
Why useSilica Sol Investment Casting?
Benefits ofsilica sol investment casting:
● Great versatility; suitable for casting most metals.
● Will allow very intricate castings to be produced with thin walls.
● Smooth surface finishes are possible with no parting line so machining and finishing are reduced or eliminated.
● Allows un-machinable parts to be cast accurately instead.
● Excellent dimensional accuracy Silica Sol Process 1.A metal die is made, the impression being the same as required in the final mould.
2.Molten wax is injected into the metal die to create a pattern, allowed to solidify and then removed. Some complex wax patterns are fabricated by joining several separate patterns together using an adhesive.
3.The waxes are then assembled on a wax tree, many parts can be put on the tree depending on size, it is common for components to be in the weight range 0.1kg up to 50kg.
4.The tree is then immersed in silica sol zircon slurry to coat the wax, the slurry is exceptionally fine with low viscosity resulting in an excellent as-cast surface finish. The slurry is coated with a refractory material and the process is repeated several times until a shell is created around the wax pattern.
5.The drying process is critical. The shells must be allowed to dry naturally in a constant temperature to allow the silica sol gels and refractory particles to bond, the result is a strong, high quality shell mould. The trees of wax are put into ovens of about 200 degrees to melt out the wax.
6.When all wax is removed the trees are heated up to over 1000 degrees to complete preparation for casting.
7.The metal is then poured into the hot mould, which allows the alloy to reach the thinnest sections of the mould before it solidifies.

Stainless Steel Silica Sol Investment Casting for Tubular Joint

Stainless Steel Silica Sol Investment Casting for Tubular Joint

You can rest assured to buy Stainless Steel Silica Sol Investment Casting for Tubular Joint from Zhiye Mechanical factory and we will offer you the best after-sale service and timely delivery. Stainless Steel tubular structures were prepared using metal nanowires/nanotubes, either Ag or Te, as templates. The Stainless Steel are formed by electron beam-induced carbon deposition on the nanowires/nanotubes and the subsequent removal of the core material by direct heating or Joule heating. We call this process ‘‘investment casting’’ of Stainless Steel. The length of the fabricated Stainless Steel varies from sub-micron to tens of microns, while the diameter and wall-thickness may vary from less than ten nanometers to over a hundred nanometers and few nanometers to tens of nanometers, respectiv......

Silica Sol Investment Casting Stainless Steel Mould

Silica Sol Investment Casting Stainless Steel Mould

Silica Sol Investment Casting Stainless Steel Mould for the casting process consist of two halves. Casting molds are usually formed from gray cast iron because it has about the best thermal fatigue resistance, but other materials include steel, bronze, and graphite. These metals are chosen because of their resistance to erosion and thermal fatigue. They are usually not very complex because the mold offers no collapsibility to compensate for shrinkage. Instead the mold is opened as soon as the casting is solidified, which prevents hot tears. Cores can be used and are usually made from sand or metal.

Stainless Steel Mold Silica Sol Investment Casting

Stainless Steel Mold Silica Sol Investment Casting , as its name implies, is a casting technique that adopts silica sol investment molds for casting manufacturing. Silica sol investment mold is a kind of casting mold that takes silica sol zircon sand as molding materials. First, make wax molds (fired molds) with fusible paraffin and stearic acid. And then coat the wax molds with silica sol zircon sands and refractory powder to make mud molds. Dry the mud molds out and put them into hot water to melt the wax molds inside. When the wax molds inside are completely melted, take them out, fire them into ceramic molds and silica sol investment molds are manufactured. When the ceramic molds are fired, a sprue gate must be reserved to allow molten metal flow in. Cool the molten metal down and cast......
