When to Use Precision Casting?

When to use precision casting

When you need a metal casting process to produce your metal project, you may not know what to do. Precision casting is an ancient metal casting process, so when is the best choice? Below, let's take a look at when this process should be used.

Here is some key information, when you come across, you may consider using precision casting.


When You Need Bulk Orders

If you need the same parts over and over again, precision casting is a good choice. It's best for situations where components are needed again and again. You can choose to order in small or large quantities. After all, the process provides consistency and repeatability as there is virtually no tool wear. In addition, it is often the process of choice for projects requiring bulk orders - which saves time and labor costs as it eliminates the need for secondary machining.


When You Need High Precision Parts

If you are looking for extreme precision, investment casting (also known as investment casting) is the way to go. Parts manufactured by this process are of high dimensional accuracy and complex shapes, and we can easily add details such as holes, lettering, threads and serrations according to customer requirements. With this type of casting, you can also obtain tight tolerances that fully meet your project's needs and requirements. besser follows the international CT standard ISO 8062-3: 2007, with linear dimension casting tolerances (DCT) ranging from DCTG 4 to DCTG 12.


When You Need Multiple Sizes

Different industries have different requirements for the parts used. Precision casting allows you to get the right part in the right size, whether it weighs 0.5 lbs or 120 lbs. Of course, there are some limitations to the size that can be cast, as the wax pattern needs to be fixed for repeated dipping into the ceramic. However, whether small castings or large castings, the process remains capable of delivering complexity, precision and tight tolerances.


When Using Multiple Materials

With this type of casting, your part or assembly can be cast in several different metals, including ferrous and non-ferrous metals. The process offers more material options than other methods such as die casting, which tends to focus more on non-ferrous metals such as lead, copper or zinc. With precision casting, we can cast your parts in metals such as aluminum, stainless steel, nickel-based, copper-based, vacuum alloys, and bronze. Additionally, precision casting makes it easier for us to cast alloys that might otherwise be difficult to machine. You can learn more about the metals we use at Dean Group on our Materials page.


When You Want a Smooth Surface Finish

There are several reasons why precision casting is a very popular casting method. One of them is its ability to obtain a higher quality finish than other methods, a requirement for a wide selection of industries and markets. For example, the aerospace sector uses high-precision parts in engines that, due to the nature of their application, need to be as smooth as possible. Die casting can also achieve a good surface finish, but usually requires secondary machining to achieve the desired results, which is often not the case with precision casting. This method can achieve near net shape with very little or no machining.


When You Need Overall Low Cost

While precision casting tends to be a more expensive process than die casting due to the superior size and high precision it produces, the final cost makes it well worth it. The process can achieve the required complexity in your parts and assemblies without wasting material, and most precision castings require minimal machining, which will save time and money.

The excellent surface finish provided by the process also reduces costs, eliminating the need for secondary machining and tooling. So while the initial cost may be a little more expensive than other methods, this is offset by the final product.

For tight tolerances beyond the capabilities of precision casting, we only need to leave a small machining allowance, and even if machining is unavoidable, the cost is relatively much lower than other processes.
