The automotive industry relies on die casting in various applications. Most cars have many metal parts that must be cast into specific shapes. Die casting is an ideal method for manufacturing these parts. When choosing a metal during the casting process, aluminum or magnesium are usually the obvious choice. These metals are very lightweight and therefore very suitable for the automotive industry.

At the same time, zinc is one of the easiest metals to cast, and zinc die castings for automotive parts have many advantages. Zinc die castings have a high level of production efficiency, excellent quality and cost efficiency. This is our guide to using zinc die castings on automotive parts, including advantages in the industry, applications and casting processes.

Benefits of zinc die casting
The benefits of using zinc for die casting include:

1. Faster die casting process: The two main die casting processes are hot chamber die casting and cold chamber die casting. Aluminum die casting requires a cold chamber method and can only perform two or three injection molds per minute. On the other hand, zinc die castings use hot chamber die castings, which can be played four to five times per minute, thereby saving time and money.

2. Maximum strength and hardness: Zinc parts are naturally stronger than aluminum or magnesium parts without any special treatment. In fact, some zinc alloys are twice as strong as the A380 aluminum alloy and 15 times as hard as the A380 aluminum alloy.

3. Greater flexibility: Zinc is a very fluid metal. It is easier to machine than aluminum, and gives you more choices when casting parts. With zinc, you can shape complex parts with thin walls. This ability compensates for the fact that aluminum is lighter than zinc.

4. Excellent thermal conductivity and electrical conductivity: Zinc has good electrical conductivity. As more and more automotive systems rely more and more on electronic devices, zinc becomes more and more important.
High corrosion resistance: Zinc parts exposed to the environment can remain beautiful for a long time. As a result, you can extend the life of the mold without continuous maintenance.

5. Environmental protection and sustainability: Using sustainable resources to produce products is more important than ever. Zinc die casting is an environmentally friendly process, and it is easy to recycle zinc parts into new zinc alloys.
Better stability and finish: Zinc has higher dimensional stability than other metal alloys, and has excellent finish characteristics, making the product attractive and attractive.

Application of zinc die casting in automobile industry
Zinc die castings have many applications in the automotive industry. One of the most important is the manufacture of parts designed to improve vehicle safety, such as seat belt assemblies. The ability to make zinc into very special parts without sacrificing the stability and strength of the metal makes zinc an ideal choice for automotive safety components.

Due to its excellent corrosion resistance, zinc is also often used to manufacture parts on the exterior of vehicles, including parts for windshield wipers, skylights and chassis. In addition, zinc often appears in door lock housings, camshaft components, brake components, components under the hood, fuel system components, etc.

Many car manufacturers prefer to make as many zinc parts as possible, because zinc casting products can usually go directly into the assembly process. They already have attractive surface treatments, so no special treatment is required. In addition, zinc parts are already very strong, so no need to add reinforcement alloys.


Zinc die castings used in the automotive industry involve a process called hot chamber die casting. Heat the zinc until it reaches the molten state, and then press it into the mold of the desired car part shape. After the metal cools and hardens, remove it from the mold. In this method, the furnace and the mold are connected as a single machine. The pressure comes from the hydraulic piston, which pushes the molten zinc out of the furnace and into the mold.
