What is Die Casting Technology?
Die casting technology
Die-casting is a process of creating metal components by forcing molten material into a reusable mold (called a die), where it fills the cavity and takes the shape upon solidification. The mold cavity shape defines the outer geometry, and the core section forms internal geometry, such as interior walls, holes, slots, ribs, and other details. Die casting technology is typically used for non-ferrous metals and alloys, such as aluminum, magnesium, and zinc.
Pressure die casting, vacuum die casting, gravity die casting, and squeeze die casting are the major types. However, each of these types follows the same basic steps: die creation, molten metal filling, die cooling, ejection, and post-processing.
The evolution of the die casting industry started in 1849 with the development of a manual pressure casting machine, which was initially used to create movable printing type. Primarily, it was for tin and lead, until zinc and aluminum were introduced in die-casting in 1914 and magnesium and copper alloys in the 1930s [2].
In the late 20th century, modernization started in die-casting equipment with automated cold & hot chamber machines, which can process several metals and alloys to produce thin-walled, complex parts/products. The current status in 2026 is the use of giga-presses, machines with ultra-high clamping forces, industrial automation, and consolidated components casting.
Currently, the Asia-Pacific region dominates the die-cast industry market with a share of ~56 % in 2025 [1]. This is mainly due to the expansion of EV, electronics, and automotive manufacturing markets in China. Chinese die-cast manufacturers also lead in supplying precise high-end die-cast parts for industries worldwide, while being cost-competitive. Consequently, other major regions in the global die-cast market are North America, South America, and Europe.
The Demand for Finished Die-casting Parts
Die-cast demand
Automotive (IC), EV, electronics, aerospace, and industrial machinery industries have an extensive demand for finished die-casting parts. For complex, lightweight, thin-walled, and integrated components, die casting delivers near-net-shape production. The high tooling expense is justified and economical for large-volume production.
Depending on the design, die casting can be more precise and cost-effective than CNC machining & multi-step stamping. However, it does not replace them completely. You must make a decision by analyzing the part geometry and production volume. For parts with ribs, bosses, deep 3D features, internal channels, mounting points, curved surfaces, and multiple integrated functions, die-casting can be a better option than stamping.

Major Processes in the Die Casting Industry: Pressure, Vacuum, Squeeze, and Gravity Die Casting
Pressure die casting is a major contributor to the die casting market revenue, with a share of ~ 55 % in 2025 [1], followed by vacuum casting, squeeze casting, and gravity die casting. High-pressure injection of molten material allows faster cycle times, complex and thin-walled geometry, excellent repeatability, and lower per-part cost.
Pressure Die Casting
The pressure in low-pressure die casting (LPDC) ranges between 0.1 and 1 MPa, whereas it can be as high as 175 MPa for high-pressure die casting (HPDC). HPDC is best for complex and repetitive parts, requiring tight tolerances, such as engine blocks and electronic housings. On the other hand, LPDC is suitable for structural and relatively large-sized components, such as wheels and suspension parts.
Vacuum Die Casting
It is a subtype of HPDC, where the die cavity is vacuumed using a vacuum pump, so air entrainment can be removed. So, the porosity can be reduced. Tooling cost is slightly higher for vacuum die casting, but it enhances the quality of load-bearing and thin-wall components.
Squeeze Die Casting
In squeeze die casting, the molten metal is poured into a pre-heated die, followed by pressure application through a punch press. It covers ~ 25 % of the industry share [3], and it is suitable for casting high-stress components, such as automotive wheels and knuckles.
Gravity Die Casting
As the name suggests, gravity is the driving force for pouring molten metal into the die, where it flows and fills the cavity without any external pressure. It reduces the turbulence and eases the subsequent heat treatment. Gravity die casting is suitable for casting parts with lower complexity in medium volumes.

Analyzing the total revenue of the die-cast industry, aluminum materials dominate the market in 2026 with a 65.10% share, followed by 21.8 % of magnesium, and 13.1 % of zinc [3]. However, the projected growth rate is higher for magnesium alloys in the 2026-3031 period.
Why Aluminum Alloys Dominate the Die Casting Industry?
Aluminum alloys offer low density, corrosion resistance, good structural performance, thermal & electrical conductivity, and are highly compatible with high-pressure die casting processes. For instance, automotive die casting components heavily use A380, A383, and A360 alloys. Demand for aluminum die casting is increasing in both IC vehicles and EVs to improve the overall efficiency.
Why are Magnesium Die Casting Applications Growing Faster?
The growth of magnesium die casting applications is driven by several factors, including the need for extremely lightweight components across the industry, the rise of EVs, weight reduction for longer battery backup time, complex thin-wall casting needs, automotive lightweighting regulations, and electronics miniaturization.
