Benefits of Zinc Die Casting in the Automotive Industry

High-pressure zinc alloy die casting is one of the most efficient and versatile high-production methods used for manufacturing strong, accurate, and complex metal components. When it comes to zinc die casting, there are two basic types. The conventional, or ZAMAK alloys, are commonly named based on their sequential development. These include Alloy 3, Alloy 5, and Alloy 7. Then there are the zinc alloys with higher amounts of aluminum than the conventional alloys, ZA. These include ZA-8, ZA-12 and ZA-27. ZA alloys offer higher strength and useful bearing properties.

The zinc die casting process is widely used for making components in industrial and building sectors, but the most common application is in the automotive industry. In fact, automobiles have different components that can be made by means of zinc die casting.

With zinc die casting, there is usually no need for machining after the process. Its accuracy is almost 100%, and cast parts can also be used because they have a smooth finish. The use of zinc die casting is just about 28% in the automotive sector, followed by hardware and building segments.

Advantages of Zinc Die Casting

When talking about the advantages of gravity zinc die casting, other casting processes can’t compare to zinc in terms of production time. A variety of casting processes are available to economically manufacture cast parts of whatever size and quantity required. However, die casting production rates for zinc are much faster than for aluminum or magnesium. Also, zinc alloys are castable to closer tolerances than any other metal or molded plastic. “Net Shape” or “Zero Machining” manufacturing is a major advantage of zinc casting. Zinc alloy die casting can produce repeatability of less than ± 0.001” for smaller components. Only a few other processes, like aluminum die casting, can achieve the same net shape performance and eliminate machining.

Another huge advantage of using zinc die casting is that zinc’s superior casting fluidity, strength, and stiffness permits the design of thin wall sections for reduced weight and material cost savings. With zinc’s excellent bearing and wear properties that allow greater design flexibility and reduce fabrication costs, we can take the most complex design specifications and turn them into a finished product quickly and efficiently.

Applications of Zinc Die Casting in the Automotive Industry

The process of zinc alloy die casting is highly popular for making parts in building and industrial fields, but its most common application is in the automotive industry. In fact, cars have different parts that can be crafted through die casting. Zinc’s high strength and hardness entitle itself to many solutions and it’s the ideal alternative to machined, pressed, stamped, and fabricated components, including:

-Interior automotive aesthetic parts

-Engine and other under-the-hood components

-Power steering systems

-Brake parts and systems

-Air-conditioning components and systems

-Fuel systems

-Complex net-shaped housings

-Electronic devices
