What Is Die Casting, Its Types, and Applications?

The time period “die forged” refers to forming a metallic object after you pour molten metallic on a reusable mildew. Die casting is utilized in quite a few industries and helps create healthcare tools, equipment parts, automotive housings, and plenty of extra. Fortunately these days, any firm can simply discover a good contractor, whether or not it’s in search of die casting in Singapore or in the US.

Supplies used for die casting are nonferrous metals like lead, magnesium, copper, zinc, and aluminum. These are most popular as a result of they find yourself forming parts which can be high-quality and strong. In most situations, as the method goes on, you possibly can add completely different chemical components to the molten metallic to assist attain a number of the metallic composition. The ultimate materials might be a number of or single casts. That is depending on the fabric, measurement, and complexity. This course of makes many metallic components helpful within the manufacturing business.

Forms of Die Casting

There are a number of kinds of die casting, however the two main ones embody sizzling die casting and chilly chamber course of. Different die-casting processes embody vacuum die casting, semi-solid metallic forming, and squeeze casting course of.   

1. Sizzling Chamber Die Casting

The primary kind of die casting is the recent chamber. That is the most well-liked kind and likewise goes by the identify of gooseneck casting. The liquid alloy comes into contact with the casting chamber throughout the course of. 

The molten metallic goes by the valve to get to the casting chamber. Because it wants to do that at excessive velocity, that’s the place the piston comes into play. 

The piston presses the molten metallic within the chamber on the acceptable price. After it goes into the die cavity, it’s below stress for full solidification. Due to the excessive stress, the recent chamber offers off the next manufacturing price in comparison with the chilly chamber course of.  

This course of is superb and handy for casting metals with low fluidity and low melting factors. These embody metals like zinc and tin.


  • Provide extra prolonged life courtesy of the low melting factors
  • There’s a quicker manufacturing price
  • Minimal wastage 
  • The top product has little or no porosity
  • Melted metallic contained in the die-casting machine


  • Warmth therapy points normally accompany the method
  • You solely save on prices if you’re doing high-volume manufacturing
  • Metals with high-melting factors are usually not relevant

2. Chilly chamber course of

For such a die casting, the molten metallic goes into a chilly chamber, particularly by an injection system. The casting chamber is stuffed with alloy after which pressed to move by the channels to the die-cast mildew. 

In contrast to the Sizzling Chamber technique, the metals used for this course of have increased melting factors like copper and aluminum. As a result of corrosive nature of those metals, they don’t seem to be appropriate for decent chamber die casting.  

Throughout the course of, the stress ranges from round 30Mpa to 150Mpa when the hydraulic plunger closes the chilly chamber port, forcing the metallic into the mildew cavity.


  • Upkeep value is low
  • The method is comparatively easy to hold out
  • There may be distinctive dimensional accuracy
  • Excessive-speed manufacturing
  • Steel casting is dense


  • The ultimate result’s more likely to be affected courtesy of pollution
  • Cycle time is slower in comparison with sizzling chamber die-casting
  • Excessive degree of contamination and oxidation

3. Vacuum die casting

The sort of casting is related to chilly chamber-type die casting. Right here gasoline and air are faraway from the die cavity courtesy of a vacuum supply earlier than introducing molten metallic. The explanation behind that is to cut back gasoline inclusion and minimize down on turbulence. Among the benefits of such a casting embody a shorter time cycle, a greater floor end, and dimensional stability.

4. Semi-solid metallic forming

The sort of casting entails the usage of semi-molten supplies. It’s well-liked in making aluminum alloy components for constructing airplanes, oil pump filter housings, engine mounts, and stress containment. One draw back to this course of is that the supplies listed here are inclined to break by environmental components like temperature. This, in flip, makes it dearer.

5. Squeeze casting course of

This liquid metallic forging technique entails each the forged and forge to make mortar our bodies and automotive parts. Dense merchandise are a results of this course of. The molten metallic is squeezed into the mildew whereas being stuffed with recessed areas of the mildew.  

Purposes of Die Casting

Most medium-sized parts with complicated components are comprised of die-casting. The method works exceptionally on aluminum, magnesium, and different nonferrous metals. 

Die casting is the main technique for producing and manufacturing industrial, industrial, and client merchandise. These embody issues like gears, connector housing, and sink taps. 

The method might be utilized in nearly all industries, like lighting know-how, equipment, electronics, energy instruments, furnishings, and home home equipment.


Die casting has been round for a very long time and has confirmed useful within the manufacturing and industrial business. We hope this text has helped you do familiarize your self with the fundamentals of the operation, together with what it entails, the benefits and drawbacks, and its purposes.
