When Should We Choose Investment Casting

Metal casting is one of the oldest but also the most basic industrial processes known to mankind. Casting began in ancient times and is used to make jewelry and weapons. Casting is a process of pouring liquid metal into certain molds to quickly produce complex shapes. In modern times, standard procedures have been developed to create highly complex parts, especially using a process called investment casting. Precision casting uses wax, slurry, and molds to produce low-tolerance, high-resolution parts without the hassle of more traditional methods. This article will introduce the process of precision investment casting, its working methods, advantages, and applications so that designers can potentially implement this technology into their projects.

Choosing the right precision casting and machining company to manufacture parts depends on the understanding of application requirements, budget, and time to market. Another important factor depends on the type of production process required. You can choose investment casting, sand casting, CNC precision machining, and other processes.


Prototype, from small batch to mass production. Investment casting involves creating a waxy pattern of parts and constructing a ceramic shell around the wax pattern to make a mold. Then the wax is melted from the mold, and then the molten metal is poured into the mold to make the part. Investment casting is repeatable because the process is designed to run consistently to produce a certain number of parts. Regardless of the quantity, precision casting is ideal for production operations. Although it can be used to make prototypes, if you want to make only one component at a time, you can choose other cost-effective measures.

High Precision

If you need high precision, precision casting (also known as precision casting) is the best choice. The parts created through this process have high dimensional accuracy and complex shapes, and we can easily add details such as holes, text, threads, and serrations according to customer requirements. With this type of casting, you can also get perfect tight tolerances that can meet the needs of the project.


Different industries have different requirements for the parts used. Investment casting can enable you to get the right part in the right size, no matter its weight is 3g or 23kg. Of course, since the wax pattern needs to be fixed to be repeatedly immersed in the ceramic, there are some limitations on the size that can be cast. However, regardless of the size of the casting, the process always maintains the ability to provide complexity, precision, and tight tolerances.


With this type of casting, your parts or components can be cast with many different metals (ferrous metals and non-ferrous metals). Compared with other methods, this method provides more material choices, such as die-casting, which tends to pay more attention to non-ferrous metals such as lead, copper, or zinc. Through investment casting, we can cast your parts from metals such as aluminum, stainless steel, nickel-based, copper-based, vacuum alloy, and bronze. In addition, precision casting makes it easier for us to cast alloys, otherwise, it may cause challenges to processing.


Although precision casting is often more expensive than die casting due to its superior size and extremely high precision, the final cost makes it excellent value for money. The process can achieve the required complexity in parts and assemblies without wasting material, and most investment castings require minimal machining, thus saving time and money.

The excellent surface finish provided by this process can also reduce costs, thereby eliminating the need for secondary processing and processing. Therefore, although the initial cost may be more expensive than other methods, the final product can offset this cost.
