Stainless Steel Investment Casting

Stainless steel investment casting, also referred to as hot stamping, is a complex precision casting process utilizing high pressure to melt the molten steel, aluminum oxide, and iron powder into a smooth mold. The resulting metal, cast in a variety of forms such as bar; rod; and plate is often used for various purposes. Some of the most common stainless steel products made out of this process include gas tanks, electric circuit boards, precision mechanical components, and precision surface finishes. Although stainless steel investment casting has been in existence for many decades, it has gained increased attention in recent years due to its usefulness in applications such as high-tech electronics and aerospace engineering. This article covers a few important facts about stainless steel investment casting and how it can be used for precision machining.


The basic model for the stainless steel investment casting process involves three separate stages. During the initial stage, the product is shaped from a billet of cold rolled steel by means of an electric press or hydraulic press. This phase is known as 'rolling steel' since it is rolled onto a die and is pressed down until it becomes thin enough to form the desired shape. This operation is crucial, since it enables the manufacturer to precisely control the thickness of the alloy in order to achieve the right diameter, length, and weight for the finished product. Once the product is successfully rolled, it is further processed by a hot gas torch to achieve the second stage of the casting process.


During the third and final stage of the stainless steel investment casting process known as post machining operation, the product is further manipulated by means of a plasma torch and hot air blasting to achieve the right finish on the cast surface. This stage also ensures that the product is free from internal stresses due to the pressure that is placed upon it during the casting process. It is important that post-machining operations are flawless and controlled to ensure consistent results each time. These operations include the removal of the waste oil, the reaming of the alloy ingots, the buffing of the surface, the final smoothing of the surface using a rotary tool and the coating of the metal with an electroplating agent.


This process is necessary in order to ensure that the welds between the stainless steel components are strong and are free from defects. During the hot gas atmosphere of the plasma blast furnace, high temperatures are reached and this causes corrosion to take place if there are exposed parts. However, this process is also necessary in order to create the forging of the metal component which is done by means of high temperature gas welding. During pouring of the molten alloy into the parts that require casting, care is needed to prevent the alloy from coming in contact with any surface, particularly those that will come into contact with the welding torches.


One more important stage in the manufacture of stainless steel investment casting is the surface finish. The surface finish is used as an impenetrable barrier to prohibit the escape of any molten substance that might result from the process. This prevents the escape of any harmful particles that could otherwise prove harmful when they come into contact with the welded surfaces. It also ensures that once the shot blasting process is complete, the surface finish is free of flaws. This is because the stainless steel sand cast or poured products must have a perfect surface finish in order to meet the required standards.


There are different types of materials that can be used for the purpose of stainless steel investment casting. The most popular material used for this casting is molten zinc. In the zinc method, the zinc is forced to pour onto the desired surface. The advantage of this type of cast is that it does not contain any loss of wax during the process and it tends to be very hard. It is mostly used in shot blasting to create components and parts that are strong and durable.
