Excellent corrosion resistance
Stainless steel is highly resistant to corrosion and rust, making it an ideal material for use in harsh environments of high temperature and pressure. Unlike carbon and alloy steels, stainless steel investment castings do not require much additional surface preparation, making them a popular choice for industrial components that must resist corrosion, such as valves and pumps.

 

Tight tolerances
The stainless steel investment casting process can meet tighter tolerances (CT5-CT6) than other manufacturing methods. This can be achieved by casting with minimal machining allowances, reducing the amount of machining work required later. As a result, stainless steel investment casting can produce net or near-net-shape products that are often not possible with other casting processes.

 

Excellent form finish
Stainless steel investment casting offers a surface finish of 3.2μm Ra, enabling the creation of intricate details such as embossed text and logos. This not only expands design options but also eliminates the need for time-consuming and costly identification processes.

 

High yield and better quality
Stainless steel investment casting produces metal parts of a higher quality. Compared with sand casting, stainless steel investment casting has a lower scrap rate, casting parts with fewer defects and higher product quality. This is unmatched by other casting processes.

 

Cut costs
The ability to achieve a high-grade surface finish through stainless steel investment casting can eliminate the need for further machining, thereby reducing secondary costs. This can result in cost savings as compared to fully finished components, as the need for a lengthy and costly process is either reduced or eliminated.

 

Mass production available, no MOQ
Stainless steel investment casting can efficiently produce a high volume of metal parts with precise consistency. However, while it can also accommodate small-batch production, the cost of tooling may make it more economical for larger production runs. The process may not be cost-effective for very small batch production.

 

Complex shapes can be cast
When the design of your components involves complex shapes and complex internal features, stainless steel investment casting not only enables the design, but also ensures that the part can be manufactured to the necessary specifications without compromising the plan for design.

Application of Stainless Steel Investment Casting

Food processing: With their corrosion-resistant capabilities, stainless steel investment castings are widely used in the food processing industry. Typical components might include food storage, coffee machine components and metal grinder components.

 

Marine applications: Stainless steel is highly resistant to corrosion, heat and abrasion, making it highly suitable for marine applications.

 

Medical Equipment: Medical equipment often requires tight tolerances and high levels of dimensional precision. Stainless steel investment casting components include dental and surgical tools, operating room equipment, implantable components, MRI machinery, X-ray equipment, stretchers, and wheelchairs.

 

Pipe Fittings: Typical stainless steel investment casting applications for pipe fittings include elbow, nipple, tee, and bushing.

Automotive Industry

Components like engine parts and exhaust systems benefit from the durability and performance of stainless steel investment castings.

Aerospace and Defense

Structural components for aircraft and defense applications often utilize stainless steel investment castings due to their strength and lightweight properties.

Fluid equipment Components

Stainless steel casting is the most widely used technique for valve & pump components. For its complicated design, stainless steel casting is able to produce any complex shape. Valve and pump components from stainless steel casting are durable enough for severe service applications.

 

Stainless Steel Investment casting process
 

Lost wax Investment casting is the most precise casting method to manufacture stainless steel casting. Especially those irregular or complex structures products. So stainless steel investment casting is almost equal to stainless steel precision casting. The stainless steel casting process contains several steps as below: mold making, wax model making, tree assembly, dipping and dewaxing, pouring, etc.

Stainless Steel Distributor

Product Design and Mold Design: This is the first step of stainless steel investment casting. Based on the product needed, we design it or get design drawings from clients.

Wax Model Making and inspection: After the mold is ready, inject wax into the mold cavity. Then take out the wax model from the mold after cooling. Inspect and Repair some appearance defects of wax models, such as slot, wax injection nozzle, flow pattern, etc. tree.

Assembly: After inspection of wax models, weld them to the casting system one by one to form an assembly. It looks like a tree, So this step is also called Tree Assembly

Shell Building: The shell building is a whole silica sol process. It will repeat and dry and harden. Firstly, dip the assembly into a good colloidal silica coating. Then sprinkle with fire-resistant sand. Until to dry and harden. To form dense refractory coating surface outside the surface of wax models. Then repeat the step 5-6 times. Finally to get a certain strength and refractoriness of silica sol shell.

Dewaxing: Put the shelling into the high-temperature oven. The wax inside the shell is melted by heating. Then drain out. Finally, we get a cavity that can be poured into the mold. This process is called Dewaxing.

Pouring: The stainless steel ingots melt into liquid status under high temperatures. Then pour the liquid into the shell and cool at room temperature.

Cutting, Grinding: Cut the stainless steel casting blanks. Remove the sprue gate by grinding machine

Surface Finishing: Smooth the surface by various surface finishes, such as shot blasting, sandblasting, electropolishing, mirror polishing, etc.

Machining: If the product needs further processing, we need machining again.

Inspection: After finishing production, Do an inspection.

 

Stainless Steel Investment Casting Surface Finishes

 

Stainless steel investment casting often uses various surface finishes to enhance appearance, durability, and functionality. Common surface finishes include:


Polished Finish: Creates a smooth, reflective surface ideal for aesthetics.

 

Electropolishing: Removes surface contaminants, achieving a mirror-like finish.

 

Sandblasting: Adds a matte texture, commonly used for non-reflective surfaces.

 

Pickling and Passivation: Removes oxidation and enhances corrosion resistance.

 

Mechanical Brushing: Provides a uniform, brushed appearance.

 

Shot Peening: Increases surface hardness, improving fatigue resistance.

 

Powder Coating: Adds color and further corrosion protection.

 

Chrome Plating: Offers a glossy, durable, corrosion-resistant coating.

 

These options allow for tailored finishes based on specific applications and environments.
