Automotive

In the manufacturing of core automotive components such as engine cylinder blocks and body structures, die casting has become the industry's preferred solution.

A die casting mold is the essential tool in the pressure casting process. Its function is to inject molten metal—typically aluminum alloy, zinc alloy, or other materials—into the mold cavity under high pressure (15–100 MPa) and at high speed (10–80 m/s). The molten metal rapidly solidifies, producing high-precision castings. The entire process takes only a few tens of seconds to two minutes.

In recent years, with the rapid advancement of new energy vehicles and mega-casting technology, the importance of die casting has been elevated to an unprecedented level. 

Haina Mold continues to deepen its expertise in this field, and the automotive manufacturing segment has developed into the company's leading business sector.

Core Technology Advantages

👉Lightweight design, empowering battery life

By replacing traditional steel structures with aluminum alloy die-cast parts—which have a density only one-third that of steel—a weight reduction of 10% to 15% can be achieved, effectively extending the driving range of new energy vehicles. The die-casting mold is the key tool enabling this efficient production.

👉Mega-Casting: Revolutionizing Traditional Manufacturing

Mega-casting technology utilizes ultra-large molds to form in a single shot structures that previously required welding together over a hundred individual parts. This dramatically simplifies the production process, improves manufacturing efficiency, and enhances product performance.

The most important thing is, the benefits brought by Integrated die-casting are substantial:

(i)   Significantly reduced part count: Structures that previously required welding together over 100 individual parts can now be formed in a single shot.

(ii)  Improved structural strength: Body torsional rigidity is increased by 10%–20%, resulting in better safety performance.

(iii) Shortened production cycle: Cycle times are reduced from several hours to just a few minutes.

(iv) Lower manufacturing costs: Following Tesla's pioneering application, manufacturing costs have been reduced by approximately 30%.
