The production process of silica sol investment casting is various, from wax pattern, shell, pouring to cleaning, which is a tight chain. Colloidal silica is a stable dispersion of millimicron size SiO2 particles in water. It's also a challenge for sand casting to make parts with internal voids or cavities. Difference of water glass investment casting and silica sol investment casting. Therefore, it is necessary to find a new precision molding process. Application of precision investment casting process. • Spectrographic and manual quantitative analysis. Machining Method: CNC Machining. The geometric tolerances that are required for the function should be specified in the drawing. Cost of solica sol casting is almost twice than the cost of water glass casting. WELD2CAST's Investment Silica Sol Casting Benefits Include: - Suitable for size castings ranging from 0, 05 kg to 30 kg. Please keep the source and address of this article for reprinting: Stainless Steel Silica Sol And Precision Casting Process. Application: Fastener, Auto and Motorcycle Accessory, Hardware Tool, Machinery Accessory.
Investment Casting Binders. Stability of Silica Sols: The discrete silica particles in a sol begin to form agglomerates when destabilized. Stainless steel and duplex grades (such as 304 (L) or 316 (L)). Process: Precision Casting. Stainless Steel Silica Sol Investment Casting Foundry with OEM Customized Service.
There are many kinds of raw and auxiliary materials, such as silica sol, wax, zircon sand, molybdenum powder, defoamer, wetting agent, steel, rare metal, etc. Range of each part weight is from 2 gram to 70 kilogram. Cast Dream has developed many components, which are often cast into particular alloys. OEM Chinese Manufacture Factory Stainless Steel/ Alloy Steel/Carbon Steel Silica Sol Investment Casting/Lost Wax Casting/CNC Machining Spare Parts Casting. Product Introduction. 5 millimeter, Hole diameter can meet as smaller as 5 millimeter. Meanwhile adhesive of water glass investment casting is water glass. Stainless Steel Alloy Steel Carbon Steel Investment Casting Parts Lost Wax Silica Sol Precision Casting with CNC Machining.
Thin walls are possible. • Machining: Turning, Milling, Lathing, Drilling, Honing, Grinding. A metal die is made, the impression being the same as required in the final mould. Most common alloys for the Silica Sol process is stainless steel, like SS 201, 301, 304, 304L / 316L, 316, 410, 416, 17-4, 329. Wetting agents are anionic, cationic or nonionic.
The most commonly used binder in investment casting is silica gel solution (abbreviated as silica sol), such as ethyl silicate hydrolysate, water glass and silica sol. The particle size distribution of the fused silica powder was analyzed as given in Fig. As most investment foundries use wax as the pattern material, steam autoclaving is the most common method used to remove the wax pattern to leave the hollow shell. Dispersed in silica sol is plotted as a function of pH values in Fig. Selecting the right casting process for your project. 01% The following greatly affect the stability of silica sols: • Ph modifiers • Soluble salts • Alcohol • Temperature Ph modifiers Silica sols are most stable in a ph range of 8. These systems are used for the casting of many types of metals. Standard: ASTM, GB, ANSI. Surface Processing: Natural Color.
Before pouring, the pattern is melted to form the cavity of the casting mold. Surface Treatment: Electroplating. But it is still weight better than sand casting process. More importantly, as the direct cavity of casting forming, the performance of the shell will ultimately affect the forming quality of liquid metal. Silica Sol Precision Casting/Alloy Steel Precision Casting/Low Carbon Investment Casting/OEM Water Glass Casting Parts/Nodular Iron Casting. The shell and core packing exposed to steam at a high pressure and a relatively high temperature within a sealed vessel will expand during autoclaving.
However, the influence of residue gas in ceramic mold on interface reaction remains…. When all wax is removed the trees are heated up to over 1000 degrees to complete preparation for casting. However, the mechanism of interface reaction in the related system remains unclear. Our efficient processes insure energy expenditure is optimized during action. Due to its good plasticity and low deformation resistance, it is not easy to produce cracks after pressure processing. What kind of file format can you open?
