The automotive industry relies on die casting for a variety of applications. Most automobiles have many metal parts that must be cast into specific shapes. Automotive Casting is the perfect method for making these parts. When choosing a metal for the casting process, aluminum or magnesium are often obvious choices. These metals are very lightweight, making them ideal in the automotive industry.

At the same time, zinc is one of the easiest metals to cast, and zinc die casting for automotive parts offers numerous benefits. Zinc die casting combines a high level of production efficiency, superior quality and cost-effectiveness. Here is our guide to using zinc die casting for automobile parts, including benefits, applications and the casting process in the industry.

Benefits of Zinc Die Casting

The benefits of using zinc for die casting include:

• Faster die casting process: The two main die casting processes are hot chamber die casting and cold chamber die casting. Aluminum die casting requires the cold chamber method, which only allows for two or three shots a minute. On the other hand, zinc die casting uses hot chamber die casting, which can allow four or five shots a minute, saving you both time and money.

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

• Greater flexibility: Zinc is an extremely fluid metal. It is easier to work with than aluminum and gives you more options when casting parts. With zinc, you can make parts in complex shapes with thinner walls. This capability makes up for the fact that aluminum is lighter in weight than zinc.

Applications of Zinc Die Casting in the Automotive Industry
Due to its excellent corrosion resistance, zinc is also often used to make parts on the exterior of the vehicle, including parts of the windshield wiper, sunroof and chassis. In addition, zinc is often found in door lock housings, camshaft components, brake parts, components under the hood, parts of the fuel system and more.

Many automotive manufacturers prefer to make as many zinc parts as possible, since zinc-casted products can often go directly into the assembly process. They already have an attractive finish, so they do not need to undergo any special finishing. Plus, zinc parts are already strong, so there’s no need to add a reinforcing alloy.
