Tips for Ordering Turbine Housings from a Stainless Steel Casting Company
1) Such steam turbine casings are customized according to customer drawings or samples. Therefore, before sending the RFQ, the purchasing company should prepare the pdf drawings and ensure that all critical dimensions and tolerances are clearly marked in the drawings. And because of its complex shape, it is better to send the 3d file in stp or igs file so that the stainless steel casting manufacturer can check each dimension clearly.
2) Since there are many choices of stainless steel grades, it is necessary to inform the manufacturer of the stainless steel grades to be cast. In general, the nickel content of stainless steel affects the price of castings.
3) For the stainless steel turbine casing to be cast, ensure that the casting method used by the potential supplier is stainless steel investment casting, not sand casting. Only investment casting can provide higher dimensional accuracy and surface finish.
4) If you want to buy a finished turbine casing, it is best to provide both the casting and finished drawings to the supplier. At the same time, it is clear that stainless steel casting suppliers can provide in-house or outsourced machining services.
As a leading stainless steel investment casting manufacturer and exporter in China, JCCASTING Foundry has developed many types of cast or finished turbine casings for customers from the US, UK, Canada, France and more. By working closely with our customers, they are always satisfied with our qualified products. Find a competitive supplier for your turbine housing project, feel free to contact us!
Brass Investment Casting Process
Almost any castable metal can be investment cast. The brass investment casting process is suitable for parts ranging from a few grams to several hundred pounds; however, most parts weigh 15 pounds or less. The first step in investment casting is to create a master mold from wax. This wax pattern can be engraved by hand or machine, and can also be produced by injection molding. A mold is an exact replica of the part to be produced. It is attached to a wax stick called a gate. Hundreds of wax molds can be attached to the same runner, or it can be a single mold. When the master mold is firmly attached, the assembly is turned upside down and dipped into a ceramic slurry called an investment mold. Multiple dips are possible to obtain a uniform coating and desired thickness.
Another method is to mount the assembly in a flask and pour the embedding material. Then let the investment dry, which takes a few hours unless the process is assisted by a fan or vacuum. Once completely dry, the components are turned upside down and baked in an oven or furnace to melt or evaporate the wax. The mold is heated more than necessary to ensure there is no moisture or residual wax inside that would interfere with the liquid brass, then poured into the space left by the wax. To completely fill the mold, the molten metal can be drawn in by vacuum, positive air pressure or centrifugal casting methods. Sometimes gravity is enough. The brass cools, and once hardened to a solid, the investment is removed to release the brass casting inside.
The bonnet is the cover of the opening in the valve body and is the second most important valve component in the pressure valve. Like the valve body, the bonnet is designed in different shapes and sizes.
The valve cover is of the same casting material as the valve body and serves as the cover on the valve body. It is usually attached to the body by threaded, bolted or welded joints. During valve manufacturing, internal components such as the stem, disc, etc. are loaded into the valve body, and then the bonnet is installed to hold everything inside.
In all cases, the connection of the valve cover to the body is considered a pressure boundary. This means that the welded joints or bolts connecting the bonnet to the body are the pressure-bearing parts. Bonnets, while a necessity for most valves, are also a concern. Bonnets complicate valve manufacturing, increase valve size, account for a significant portion of valve cost, and are a source of potential leaks.
Bonnet stainless steel investment casting
Stainless steel casting is an investment casting process that offers many benefits when used to produce precision components such as valve covers. A stainless steel investment casting process can help save costs while bonnets are available through OEM service. Here are some of the benefits you can get when using the stainless steel casting method to make valve covers.
Durability
One of the biggest advantages of stainless steel bonnets over other types of metal bonnets is that they are very durable and strong. Cast stainless steel bonnets can be used in any type of temperature without any problems when used in extreme hot or cold temperatures. When a company chooses to buy high-quality cast stainless steel valve covers, they can count on them to hold up well for a long time. Given the durability and longevity of stainless steel bonnets, they are a very good investment and affordable in the long run.
No corrosion
Cast stainless steel bonnets are not prone to rust or corrosion. This makes the use of cast stainless steel bonnets the preferred choice for industrial applications where conditions can cause the metal to rust or corrode quickly. While cast iron bonnets are also less prone to rust or corrosion, they do not have the strength, durability or high pressure resistance of cast stainless steel bonnets.
Design flexibility
At JCCASTING, we have an unlimited selection of stainless steel grades, giving you the flexibility to configure your castings according to your needs. This includes even very complex shaped or hollow section parts, helping to configure them in a robust and repeatable way. This flexibility also brings the ability to make changes faster and in less time from design to seeing the finished product. Additionally, stainless steel investment casting is a repetitive process that can efficiently produce valve covers. This is because a mold is created, making the process more repeatable and efficient when creating multiple castings.

Stainless steel casting is a well-known method because it can produce complex shapes. Metals that are difficult to manufacture or form use this method. In this way, it is also possible to manufacture products and parts with complex shapes that cannot be manufactured by ordinary processes. In addition, parts that need to withstand harsh temperatures are manufactured in the process.
The core alloying elements of stainless steel investment casting include molybdenum, nickel and chromium. These elements will perfect the mechanical properties and grain structure of the casting. They also contribute to the heat and corrosion resistance of the casting. Other elements used to make stainless steel castings include silicon, nitrogen, manganese and iron ore.
Making stainless steel castings will first involve melting the steel and then casting it into solid form. After forming, it is heat treated, cleaned and polished. After that, it will be sent to the manufacturer, who will weld and combine it into the desired form.
