Machined Casting is a great way to produce parts with high precision. This method is specially adapted for the post-processing of die-cast parts. Sunrise Metal has both die casting and CNC machining facilities available that allow us to produce high-precision parts.

You will find most of the common queries regarding Machined Casting in this guide. If you have any further queries feel free to contact our customer support.

What is Machined Casting?

Machined Casting refers to the machining of already cast or forged parts. It is basically a compilation of Casting and Machining. This is commonly a commonly practiced technique for producing die-cast parts with better quality and precision.

It can be used for getting rid of excess material after die casting of parts. It is also used for providing geometric features that are too complex or not possible during the casting process.

Sunrise Metal is a leading Aluminum Die Casting Manufacturer who also has advanced CNC Machining facilities. So, we are capable of Machined Casting your parts ensuring top-notch quality and precision.

What is the process of Machined Casting?

There are some fundamental steps to be followed for the Machined Casting parts.

  • To get started you will need a 3d model of your desired part.
  • Prepare a die casting die according to your parts design.
  • Produce Castings using the dies.
  • Prepare DFM for the casting.
  • Machine the raw castings to remove excess material from the body.

This is actually a lengthy process. But only the major key steps were listed for your easier understanding.  Here’s a video showing the machining process of casting.

What are the advantages of Machined Casting?

Machined Casting has multitudes of benefits that make it a preferable choice for the manufacturers. Let’s have a look at the advantages it has to offer.

High Tolerances

Parts with very tight tolerances can be produced by Machined Casting. Parts produced by direct casting methods can’t yield parts that are close to CNC Machined parts.

The results obtained will be almost similar to parts produced entirely by CNC Machining. But the cost will be much lower compared to CNC Machining from scratch.

Complex Geometry

Machined Casting can produce complex parts that are hard to produce by a regular casting method. Some special geometric features are often impossible to implement by casting.

It also enables manufacturers to mass-produce complex parts. Firstly, a basic shape can be formed by die-casting then it can be machined to provide the special features.


Production of high-precision parts can take a great deal of time. But, Machined Casting can get similar results with less time.

The required parts can be manufactured using a fast casting method such as Die Casting. Then the parts can be machined to achieve a greater level of precision.


Machined Casting is a cost-effective alternative to CNC Machining. High-precision parts can be manufactured without having to worry about the high machining costs.

How much precision is achievable by Machining on Castings?

The Machined Casting process involves using CNC Machines. Sunrise Metal has a wide range of CNC Machines including high precision and high-speed CNC Machines. We have the latest 7-Axis CNC Machine and 5-Axis CNC Machines as well.

Our advanced machining facility can achieve a precision of about ± 0.005 inches for Machined Cast parts. We can achieve more precision, but that is often not preferred by the manufacturers as it will significantly increase the cost.

Machined Casting is popular for its ability to produce parts with high repeatability. It will yield parts with a high level of accuracy with constant quality. That’s why manufacturers prefer it for the production of high precision parts.

What are the machining processes involved in Machined Casting?

The final step of Machined Casting is done by CNC Machining. There are many types of CNC machining processes. The usage of a particular machining process usually depends on the geometry of the product being manufactured.

The most common CNC Machining Processes are:

  • Milling
  • Drilling
  • Turning

These are all different processes and require a different type of cutting tools. The similarity among them is that in each case, either the tool is rotated against the workpiece or the workpiece is rotated against the tool.

There are other miscellaneous processes such as,

  • Boring
  • Grinding
  • Sawing
  • Reaming etc.

The parts may need multiple machining processes for attaining the desired shape depending on its geometry.

What materials are suitable for Machined Casting?

Machined Casting can be done on a wide range of materials. But, the suitability of the materials depends on the scope of usage of the parts. There may be difficulty in the usage of a certain material due to the type and size of a part being produced.

The commonly used materials are:

  • Aluminum
  • Steel
  • Brass
  • Zinc
  • Copper
  • Plastic etc.

There are different variants and alloys for each type of material. The material you will be choosing should be suitable for both Casting/Forging and Machining.

When do I need Machined Casting for my parts?

Machined Casting involves both machining and casting. You must be wondering when it is a better choice.

It is adopted by manufacturers as a means of mass-producing high precision parts. You can also improve the accuracy of your die-cast parts and fix flash defects that may result after die casting.

It has been a good method for achieving similar results of CNC Machining a part. But CNC Machining is a bit expensive and not suitable for mass-production.

Machined Casting overcomes these issues and combines the benefits of both casting and machining for producing high-precision parts cost-effectively.

What industries are using Machined Casting?

Machined Casting is preferred by industries that have a need for high-precision parts. The big industries need large volumes of parts. CNC Machining all the parts would simply be too costly. Machined Casting can help in this case.

Here are some of the major industries that rely on Machined Casting,

  • Automotive
  • Aerospace
  • Medical
  • Electronics
  • Marine
  • Telecommunication
  • Military

These are just to give you a rough idea. Of course, any industry that has a need for precision parts can choose Machined Casting. It offers a good balance between the cost and quality of production.

Can Machining correct flash defects in die-cast parts?

Flash defects are a type of casting defect that commonly occurs during die casting of parts. It is an excess portion of metal attached to the castings. They are usually trimmed using a trim die or removed by the Machined Casting process.

Flash defects usually happen when the injection pressure in high-pressure die casting is too high. It causes the molten metal to leak through the joint of the dies. But, that is often unavoidable if there are a higher precision and strength requirement.

It can also happen because of a lack of clamping force. That can be fixed by higher tonnage equipment but that would also cause the cost of production to go up.

Machined Casting can be used to machine parts with flash defects cost-effectively. It will ensure both the quality and precision of the parts.

What is your production capacity for Machined Casting?

Machined Casting production capacity depends on the Die Casting and CNC Machining capacity. The overall lead time is somewhat longer than simply die casting but takes less time than CNC machining all of the parts.

Machined Casting doesn’t require machining a part from scratch. So, A large number of parts can be produced in a shorter period.

But, an estimate of an exact figure is not possible. It depends on a lot of parameters. You can Request for Quote of your parts to get a better estimation of the production capacity.
