Difference Between Machining and Die Casting


Machining, especially when it involves Computer Numerical Control (CNC), simplifies the operation by sculpting the object out of metal using robotics. Its processes include straight turning, taper turning, form turning, contour turning, boring, drilling, and milling. Machining also uses exotic and precious metals such as:

  • Tantalum
  • Superalloys
  • Platinum
  • Palladium
  • Niobium
  • Monel
  • Molybdenum
  • Kovars
  • Iridium


Melting metal and inserting it into a steel mold is the process of die casting (the die). The metal is then cooled until it solidifies into the desired shape. The common materials used in forging are titanium, carbon steels, tantalum, superalloys, cobalt alloys, stainless steels, Rene, Inconel, Haynes, and alloy steels.

To get cheaper treatment costs, you have to determine which is appropriate for your business.

It is prudent to exercise caution while making an early investment in a project, especially if your budget is limited. If you’re not sure which strategy is best for you, talk to our Ferralloy professionals about it.

Which One to Choose: CNC Machining or Die Casting?

Computer Numerical Control (CNC) machining is more costly than die casting, but this varies depending on the production volume and kind of parts. It is frequently used to make the die and/or to add more advanced functionality to a die-cast product. Here are some of the factors to consider when comparing the various procedures to boost castings investment.

Factors to Consider


Die casting leaves only a few scraps steel behind, making it more economical. When slicing away sections of a metal block, CNC machining can end up leaving a lot more waste. If you want to reduce waste but prefer CNC machining, you’ll need to set up a recycling system so that scrap metal may be reused.


Die casting can produce complex geometrical shapes with precision, but it can also produce surface defects such as flashes or burrs, which require machining to remove. CNC machining, especially for highly customized small parts, may produce final products with a high level of tolerance and precision. Die casting is still a fantastic alternative for making identical parts when the surface detail can be carved into the master mold.


Die casting is simpler, faster, and more reliable than CNC machining. Even if post-casting machining is needed, it will take much less time than machining a complicated object from a solid piece of steel. Die casting is more reliable for creating large quantities because of its faster production cycle. However, CNC machining might generate a shorter lead time when producing lower numbers if you have the digital model ready. When developing prototypes, it can also be quicker.

Reasons to Use Sand Castings

Flexible Mold

The mold boxes made up of sand casting are extremely reliable and easy to make.  The sand mold can hold the metal’s shape as the metal cools down to reveal the desired cast design. The use of sand casting allows you to create highly complex shapes in almost any size and form from nearly every type of engineering alloy.   

Cost-Effective and Relatively Cheap

One reason why most metal castings around the world are manufactured using sand casting is that it is relatively cheap and cost-effective. Sand casting is one of the few available processes for metals that can be recycled because of its reusability. Its ability to mold sand to be reused is a great asset in manufacturing operations.  

Strong and Resilient

Sand casting molds provide the best outcome possible because it can withstand the high temperatures of liquid metal it holds when creating designs. It can also manage thermal contraction, metal flow, and gas venting to prevent defects and impurities during the process. By using high-quality sand in creating the mold, your project will not melt, burn, or crack as molten metal is poured into it.

How Exactly Is Machining Done?      

Three Primary Tools of Machining    

Machining is divided into the following sorts of machining tools, which are described in detail:     


Turning is a lathe operation that involves removing metal from a workpiece outside its diameter with a cutting tool. This process is carried out on a lathe, which is a machine that allows the workpiece to be adjusted while the tool remains fixed and rotates the workpiece.   

Lathes are intended explicitly for turning operations and aid in the most exact cutting of metal. The workpiece is inserted into the chuck, and the machine spins the fixed tool to remove the undesired bits.     


Drilling is a method of making holes in metal using circular cylinders. This task is completed with a twist drill. The drilling procedure removes 75 percent of the metal cutting material.   

The drill is inserted into the workpiece and makes a hole the same diameter as the instrument used to cut the whole. The pointed end of a drill allows it to carve a hole in the workpiece readily.    


Milling is one of the most basic machining procedures. Because the degree of freedom is excellent, this manufacturing technique is less precise than turning procedures. Milling is used to create objects that are not axially symmetric. For this, you’ll need a milling machine, as well as a fixture, cutter, and, of course, the workpiece.     

The workpiece, in this case, is a pre-shaped material that requires milling. It’s clamped to the fixture and ready to be milled. The workpiece is passed through the cutter, which eliminates the undesired metal.

How were Investment Castings Used in the Past?

Investment casting, otherwise known as a lost wax casting, is one of the oldest metal-forming processes that is still used as of this date. Approximately 5,000 years ago, investment castings started with a basic beeswax-formed pattern. Today, it involves highly complicated processes and technologies using refractory materials and specialized alloys.

what should i know about investment castings?

The History of Investment Castings

Original Use

The use of investment castings in ancient civilization was a bit different from the current method applied today. In the olden times, the craftsman designed the casting from beeswax by using basic tools such as shaving tools, melted wax, and other hot tools. To create the desired form, the craftsman will forge a pattern on the wax shape.

They will then fill the mold with a thin layer of melted wax. As soon as the wax mold is coated in ceramic, a perfect mold of the wax shape can be created. It will then be left to dry out before the craftsman can use it to forge a metal object. Such a process is generally used to create jewelry, decorative objects, and religious objects.

Modern Use

Investment casting is a complex metal-forming development that allows metal workers to create products with intricate and remarkable surfaces. The process starts by creating a mold and producing accurate patterns through the latest technological advancements. The good thing about the modern application of investment castings is that when the workers use wax to make patterns, it can still be reused.

The flexible patterns allow for easy reproduction and stress-free production of wax materials that underwent a series of coating and hardening. Once the materials are invested – jargon for poured – into the mold decorated with unique patterns, it will go through a lot of processes such as dewaxing, heating, pouring, removal, and cleaning.
