Die casting is a manufacturing process used to produce metal parts with high precision, smooth surfaces, and intricate shapes. It involves forcing molten metal, typically non-ferrous alloys like aluminum, zinc, magnesium, lead, or copper into a reusable mold called a die. The die is custom-made to match the desired shape of the final product. 
Die casting reduces or eliminates the need for additional steps in making metal parts, but post-machining is often used for precise tolerances. Die casting parts can have the same finishes as CNC machined parts. 
Similar to injection molding, Die casting requires a mold tool called a die with one or multiple cavities. It is suitable for softer alloys like aluminum and zinc because they have lower melting temperatures. 
During the process, molten metal is injected into the die cavity, taking the shape of the part and then solidifying. Depending on the project, die casting can be low or high-pressure using a ladle or plunger to deposit metal. 
Die casting can efficiently produce complex and precise parts at high volumes. Modern methods like squeeze casting and semi-solid metal casting are used to create high-quality parts for various industries. 
Die casting companies often specialize in casting aluminum or zinc, with aluminum accounting for about 80% of die-cast parts.


Die casting process is producing metal parts by forcing molten metal under high pressure into a mold cavity. The molten metal solidifies rapidly to create the desired shape. The die casting process works fast: the hot chamber die casting process can reach 4-8 injections per minute; the cold chamber die casting process is 1-3 injections per minute for small parts.

7 Steps Of The Die Casting Process

1. Mold Preparation:

A two-part steel mold, called a die, is created. The die consists of a fixed half (the "cover die") and a movable half (the "ejector die"). These halves are precisely machined to form the desired part shape.

2. Clamping:

Clamping in die casting refers to the process of securely holding the two halves of the mold together during the injection of molten metal.

3. Melting and Injection:

The selected metal, typically an alloy with desirable properties such as aluminum, zinc, or magnesium, is melted in a furnace at high temperatures. Once molten, the metal is injected under high pressure into the die cavity through a system of runners and gates using a hydraulic or mechanical press.

4. Cooling and Solidification:

After the molten metal fills the die cavity, it quickly cools and solidifies due to contact with the cooler die surfaces. Proper cooling time is crucial to ensure the part achieves the desired strength and dimensional accuracy.

5. Ejection:

Once the part has solidified, the movable ejector die opens, and ejector pins push the part out of the die cavity. Sometimes, additional features like cores are incorporated into the die to create internal shapes or holes in the part.

6. Trimming and Finishing:

The ejected part may have excess material, called flash, which needs to be removed. Trimming or machining processes are employed to remove this excess material and achieve the final dimensions and surface finish required for the part.

7. Post-Treatment:

Depending on the specific requirements of the part, additional processes may be applied. These can include heat treatment, shot blasting, surface coating, or other finishing operations to improve the part's mechanical properties and appearance.

Die Casting Zinc Alloy adds elements: aluminum, copper, magnesium, etc. With high density and high ductility, good impact strength, and very good surface smoothness, zinc can form very thin or fine parts, and its low melting point (380°C) means that the cast die will be in use for far longer than dies used for some other metals. Because of zinc's susceptibility to corrosion, it often requires additional coating or plating before use.

    Die Casting Zinc alloys types:
    Zamak-2, Zamak-3, Zamak-5, Zamak-7, ZA-8, ZA-12, ZA-27
    We offers the most popular types of Zamak and ZA die casting zinc alloys: Zamak-2 (ZA-2), Zamak-3 (ZA-3), Zamak-5, Zamak-7, ZA-8, ZA-27.

    Magnesium features: extremely low density, high strength, good fluidity, great corrosion resistance, and easy filling of complex cavities. Its melting point is 520°C. The main alloying elements of magnesium die casting alloy are aluminum, zinc, manganese, cerium, thorium, and a small amount of zirconium or cadmium.

    Die Casting Magnesium Alloys Types:
    AZ91D, AZ31B, AM60B, AZ63A, AM50A, AZ92A, AS41B
    The most common Die Casting Magnesium Alloys is the AZ91D.

    Magnesium Alloy Die Casting Characteristics and Advantages:

    1. Toughness
    2. Durability
    3. Lightweight
    4. Good castability
    Magnesium alloy is 75% lighter than steel and 33% lighter than aluminum without losing strength. It is better for complex die-casting parts with tight tolerance and has good corrosion resistance. So, it is widely used in the Electron electricity Products, Rail Transit, Automotive, and Military industries.



  • Copper Alloys

    Copper and copper alloys are incredibly stable, conductive, durable, corrosion and wear resistant. As copper alloys have a greatly high melting point, that cause dies and casting chambers used to treat this particular metal tend to have a significantly shorter lifespan than those used to treat aluminum or zinc metals.

    Commonly used Die Casting Copper alloys:
    YT40-1 (YZCuZn40Pb), YT16-4 (YZCuZn16Si4), YT30-3 (YZCuZn30Al3), YT35-2-2-1 (YZCuZn35Al2Mn2Fe)


    (Die-casting copper alloy Grade, chemical composition, mechanical properties, and application)

  • Lead Alloys

    Lead alloy is a kind of metal that is high density, soft, and malleable with a low melting point. Die Casting Lead alloy is added 3~5% Sb. alloy to Lead. Antimony alloy makes the soft Lead harder and easier to eject from the mold cavities during the die casting process.
    Usage of Die Casting Lead Alloy:
    1. Lead acid battery terminals, Lead acid battery bushings, Lead acid battery connectors, Lead acid battery spare parts.
    2. Finishing sinker, Lure bait, Weight parts
  • Tin Alloys

    Tin alloys provide high density and extreme accuracy. Its main property is corrosion resistance. Same to Lead alloy, Tin also is the first metal used in the die-casting process. To ensure public health, the use of lead and tin is prohibited in any food service applications. they are typically used in combination with aluminum, zinc, and copper alloys to prevent corrosion.

Die casting finishes refer to the surface treatments or coatings applied to die-cast components or parts after the casting process. These finishes serve various purposes, such as improving the appearance, enhancing corrosion resistance, providing additional protection, or adding specific functionalities to the die casting parts. Some common die casting finishes include:
  • Standard (As-cast)

    "As cast" is a die casting finish that refers to leaving the die-cast part in its natural state after the casting process is complete, without any additional surface treatments or coatings. In other words, the part is used as it comes out of the die-casting mold, with no further finishing operations applied to its surface. Zinc and Aluminum alloys parts can be left as -cast and retain reasonable corrosion resistance.
  • Shot Blasting

    Shot blasting is a surface treatment process used to clean, polish, or prepare the surface of a material, typically metals, by propelling small, abrasive particles at high velocity.
  • Vibration grinding / Media Tumbled

    Vibration grinding is a surface finishing process used to deburr, polish, and improve the surface quality of die casting parts.
    Media Tumbling is a specific type of vibratory finishing that uses tumbling media, such as ceramic, stone, stainless steel balls, etc, to achieve the desired surface finish. The tumbling media act as both abrasive agents and assist in separating the workpieces to avoid excessive contact, preventing part-on-part damage.
    The magnetic grinding machine uses magnetic field force to transmit to the stainless steel grinding needle to make the workpiece rotate at high frequency, thereby polishing and grinding the inner holes, dead corners, and gaps of the hardware workpiece to remove burrs, ultimately achieving the effect of rapid removal of burrs and dirt from precision workpieces.
  • Anodizing

    Aluminum anodizing is an electrochemical process that enhances the surface of aluminum by forming a durable oxide layer. This oxide layer, called an anodic coating, not only increases the aluminum's resistance to corrosion but also provides a base for various decorative and functional finishes. The surface of an aluminum die casting part does not facilitate a cosmetic finish with anodizing.
  • Powder Coating

    Powder coating is a popular method of applying a protective and decorative finish to various materials, including metals, plastics, and ceramics. So, all die cast parts can be powder coated. It is an alternative to traditional liquid paint and offers several advantages, such as increased durability, environmental friendliness, and a wide range of color options.
  • Painting

    Electroplating is a common finish used to apply a thin layer of metal (e.g., nickel, chrome, zinc) onto the die-cast part's surface. Plating enhances the appearance, provides corrosion resistance, and may offer improved conductivity.
  • Plating

    Electroplating is a common finish used to apply a thin layer of metal (e.g., nickel, chrome, zinc) onto the die-cast part's surface. Plating enhances the appearance, provides corrosion resistance, and may offer improved conductivity.
  • Chromate Conversion Coating

    Also known as chemical conversion coating or chromating, this process creates a thin, protective layer on the surface of the die-cast part. It improves corrosion resistance and can serve as a base for subsequent painting or bonding.
  • Polishing and Buffing

    Mechanical processes like polishing and buffing can be used to enhance the surface appearance and provide a smooth, reflective finish to the die-cast parts.
  • E-Coating

    Also known as electrophoretic coating or electrocoating, this process involves immersing the die-cast part in a bath of paint suspended in water and applying an electric charge to deposit the coating evenly. E-coating provides excellent corrosion protection and covers complex shapes evenly.
  • Passivation

    For certain metal alloys, passivation is used to remove surface contaminants and create a passive oxide layer, which improves corrosion resistance.
