Stainless Steel Casting of Glass Spigots

Glass spigots are the stainless steel hardwares that are fitted with glasses to creat fenced areas around entrances, walkways, decking or swimming pools, etc.

With these spigots, you can construct pool fencing with more security measurement, and you can avail better longevity also. These spigots are rust resistant and water, air pollution and humidity level cannot affect these spigots.

Material: 316 or 2205 Duplex Stainless Steel

According to its special working environment, the common stainless steel grades of glass spogits are 316 or 2205 duplex stainless steel. Both grade 316 and 2205 stainless steels are suitable for the casting of glass spigots. By comparison, 2205 duplex stainless steel contains higher contents of chromium, nickel, molybdenum and nitrogen elements. This results in a stronger glass spigot, moreover, 2205 glass spigots are more corrosion resistant and durable than 316 ones.

But it does not mean 316 stainless steel is not ideal, at least it is cheaper while can still meet the basic requirement of glass spigots. 316 stainless steel is always regarded as marine grade stainless steel, so it is actually enough to produce glass spigots. But if you want to longer the serving life of glass spigots, 2205 duplex stainless steel can be considered.

Stainless Steel Casting Process

Stainless Steel Casting of Glass Spigots

Stainless steel casting of glass spigots is an OEM lost wax investment casting process. In the market, there are different shapes and dimensions of glass spigots, including round spogits, square spogits, etc.

The stainless steel casting process is simple and straightforward, yet capable of producing highly detailed glass spigots with tight tolerances. To start the manufacturing process, a precise mold is created from either CAD drawing or 3d file. Once completing the mold, wax is injected and fully filled into the mold to create a wax pattern, which have the same shape of the glass spigot.

Finished wax patterns are then assembled onto a sprue like a tree, which includes several wax patterns. Then, repeatedly dipping the assembly in ceramic slurry and coating with sand several times to form a ceramic shell mold. Afterwards, dry the shell under room temperature.

Next, heating the hardened ceramic molds in the oven to remove the wax, thus to achieve the empty mold cavities. Molten stainless steel is then poured into the ceramic shell for solidification. After cooling, remove the surface shell and cut the individual glass spigot from the assembly. Finally, grind and shot blast the cast glass spigots to obtain clean surface.

The whole casting process of stainless steel glass spigots is almost the same as other stainless steel castings, just adjust the process slightly according to the structure of the part. Due to the large volume, CFS Foundry can ship glass spigots every month.

Benefits of stainless steel casting of glass spigots include: Great dimensional accuracy, little to no material waste, lower per-part cost and short lead time.
