Machined Investment Castings

The company is supplying a beverage industry equipment manufacturer with two versions of these investment cast components.  The 3 pound and 4 pound versions of the 316L investment castings were originally produced as  fabrications  from plate and bar stock.  The components were welded together and then machined.  By utilizing the investment casting process, the subassembly was able to be produced in one-piece and then finished machined.  This process change resulted in a cost reduction to the customer as well as becoming a more aesthetically pleasing component.

Machined Investment Casting | The Machining Process

To obtain many specific metal components there are certain processes that the metal undergoes. For products like a machined investment casting components, it needs to undergo a process after the part is casted called machining. We have already discussed what machining is, but there are several different tools and processes within machining that are specific to the component and its purpose. Depending on what the machined investment casting components will ultimately be used for, the type of machining it undergoes could vary. Curious to find out what types of machining are available for your metal components? Keep reading to find out more!

Machined investment casting is a specialty of Ferralloy.

Types of Machining 

The technology involved in the process of machining varies between different tools used for cutting. There are times where a machined investment casting needs a certain texture or a very specific measurement, and in each case a different tool is utilized. A few of the different types of machining operations include turning, drilling, boring, reaming and milling. In turning a single edge cutting tool is used to remove excess material from a rotating component and create a cylindrical shape. In drilling a round hole is being created and in boring, which is similar, a single bent tip is used to improve the accuracy of an already roughly made hole. Reaming removes a small amount of excess metal from an already drilled hole and milling is a rotating tool with several cutting edges that is utilized to create a straight surface.

Machined Investment Casting Applications

Investment casting is used in aerospace and power generation industries to create a variety of components. Machined investment casting includes the process of machining the component after it has been manufactured in order to have it delivered to the company’s exact specifications. In these types of industries, it is important to ensure that any exact measurements are achieved in machined investment casting, and Ferralloy Inc has the experience and authority to provide this service and product to you. As an industry leader, Ferralloy, Inc is equipped and experienced in delivering high quality metal components at competitive prices. Contact our metal component manufacturing company today!

From Sand Casting to Investment Casting

A large manufacturer of industrial motors requested Ferralloy, Inc. to redesign an internal motor component, so as to eliminate a large portion of the machining required to finish it.

By utilizing the investment casting process, the company was able to reduce the weight of the casting and actually ‘cast in’ a few features that were machined into the former design.

The reduction of weight, the near net shape of the redesigned casting and the reduced machining time, all contributed to a significant cost reduction for the customer.

Heat Resistant Castings | Steel Mill Application

There are a variety of applications where heat resistant castings are needed. Especially when temperatures reach extremely high levels, making sure that components in the equipment being used will withstand the circumstances is important in order to ensure the manufacturing process is successfully accomplished. What kind of applications benefit from heat resistant castings? The focus of this article will be on steel mills and how they accomplish what they aim to produce with heat resistant castings.

High quality heat resistant castings are available from Ferralloy Inc.

What are Steel Mills?

Simply put, a steel mill is an industrial plant used to manufacture steel. There are several processes that can take place in a steel mill; sometimes the iron ore is being processed in to steel and sometimes there are casting parts that are being manufactured from pig iron or scraps. In an integrated mill, the primary functions include iron making, steel making, casting, roughing rolling and product rolling.

For all of these processes to take place, different types of furnaces are employed, including a blast furnace where raw materials are integrated and liquefied. Heat resistant castings in this case are needed within the furnaces that can reach 2000oC. Furnace rolls and heat resistant castings are employed within the furnace being used to liquefy the raw ores into molten iron.

Heat Resistant Castings

For all different types of applications, it is important to have high quality metal parts that will withstand the strains of whatever processes you intend to do with them. High quality heat resistant castings can be produced and delivered for your project from Ferralloy, Inc. We have the technical authority to produce high temperature alloy components for your manufacturing needs. Our goal is to provide you with high quality parts are the most competitive cost. The range of products that we have the capability of producing is wide, so contact Ferralloy, Inc about your heat resistant casting needs today!
