What are zinc alloy die casting parts?

Zinc alloy die casting parts is a kind of pressure casting part. Zinc alloy die casting parts uses a pressure casting mechanical die casting machine equipped with a casting mold, which pours liquid zinc or zinc alloy into the inlet of the die casting machine. Then die casting parts by the die casting machine to produce zinc alloy die casting parts that are restricted by the shape and size of the mold.

What are the characteristics of zinc alloy die casting parts?

The zinc alloy die casting parts is carried out in an automatic machine suitable to withstand high pressure. The molten metal is pushed into a two-piece steel die containing one or more cavities, each an exact inverse replica of the part or parts. The mechanical properties of zinc alloy die casting parts are generally superior to other casting processes because of the quick chill and rapid solidification that takes place when the molten metal comes into contact with the relatively cool steel side.

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

Another huge advantage of using zinc alloy die casting parts 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 excellent bearing and wear properties of zinc alloy die casting parts, it can allow greater design flexibility and reduce fabrication costs.

 

What are the types of zinc alloy die casting parts?

When it comes to zinc die casting parts, there are two basic families. The conventional, ZAMAK alloys are commonly named based on their sequential development. These include Alloy 3, Alloy 5, and Alloy 7. Then there are the zinc alloy die casting parts 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.

Alloy 2 offers the highest strength and hardness of the conventional zinc alloy die casting parts. Alloy 2 of zinc alloy die casting parts exhibits excellent castability and maintains higher strength and hardness levels after long term aging. This type of zinc alloy die casting parts is a good bearing material, and may eliminate bushings and wear inserts in die cast designs.

Alloy 3 is the most widely used zinc alloy die casting parts due to an excellent balance of desirable physical and mechanical properties, superb castability and long-term dimensional stability.

Alloy 5 is the most widely used zinc alloy die casting parts, which has excellent castability characteristics and improved creep performance over No. 3. However, these improvements are accompanied by a reduction in ductility that can affect formability during secondary bending, riveting, swaging or crimping operations.

Alloy 7 is a modification of No 3 with a lower magnesium content and tighter impurities specification, resulting in improved casting fluidity, ductility and surface finish.

As a good gravity casting alloy, ZA-8 can also be hot chamber die cast and is readily plated and finished using standard procedures for conventional zinc alloy die casting parts.

ZA-12 is the best gravity zinc alloy die casting parts for sand, permanent mold and the graphite mold casting process. As an excellent bearing alloy, plating adhesion of ZA-12 is reduced compared to the conventional zinc alloy die casting parts.

ZA-27 is an exceptionally strong zinc alloy die casting parts, which is light and has excellent bearing and wear performance.

 

What can zinc alloy die casting parts be used for?

Zinc alloy die casting parts is one of the most efficient and versatile high-production methods used for manufacturing strong, accurate, and complex metal components.

The process of zinc alloy die casting parts 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 zinc alloy die casting parts, so much so that the modern process of zinc alloy die casting parts originally started for the automotive industry. Zinc’s high strength and hardness lend itself to many solutions and it’s the ideal alternative to machined, pressed, stamped, and fabricated components. Many applications can be zinc alloy die casting parts manufactured, 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, and electronic devices.
