OEM Welding Zinc Die Casting Parts

Welded zinc die casting

Our zinc die castings are welded. The surface is sprayed with powder coating. Zinc die castings have various excellent physical and mechanical properties, castability and finishing characteristics. Compared with any commonly used die-casting alloy, the section that can be die-cast with zinc alloy is thinner. Zinc die-casting parts can usually make the design changes of the profile larger and keep smaller dimensional tolerances. Except for brass, the impact strength of zinc die castings is higher than that of other die casting alloys. Due to the low pressure and high temperature of die-cast zinc alloy, it can significantly extend the life of the mold and minimize mold maintenance. Has a great advantage.

What is die casting?

Die casting is a method of injecting pressurized molten metal into a mold. The liquid metal enters the cavity through the holes in the preset mold half. The melt is guided into the cavity through channels called runners (called half of the top mold) (the complementary part of the mold). The two pieces are clamped together by a series of pins fixed in place. The metal is then cooled to just above its melting temperature, quickly forming it into a die-cast part. Another set of pins ejects the die casting to eject the assembly.

The die casting itself is composed of steel alloy. They consist of two parts to allow the casting to be removed from the mold: the fixed mold half and the ejection mold half. Other molds have additional movable parts that can be inserted or extracted to create specific shapes in the casting. The mold is cooled by air or water. Holes in the die-cast parts allow air to enter or inject the coolant, thereby facilitating the process. The rapid cooling of the mold allows for rapid cycling, thus beating another round of clockwork-like molds in a considerable period of time: such a die-casting mold can promote more than 5 million castings in a lifetime.

Compared with other manufacturing processes, die casting has some stable advantages. It is fast, competent, and easy to use, and it is available in a variety of shapes and fragments, not to mention durable. After that, since the process can maintain a consistent endurance even for the most complex part shapes, the possibility of editing by machining is very low. Most importantly, castings can be easily modified by plating and/or finishing. These lightweight parts are individual parts that can maintain the strength of the alloy, thereby increasing its stability and heat resistance.

Why zinc?

1,Zinc has a variety of properties and has unique advantages in many die casting applications. These include a combination of strength, ductility, resistance to catastrophic damage, impact strength and finishing characteristics

.
2,Miniature zinc parts can meet and exceed the standard linear dimensional tolerance of +/- .002" and the precision linear tolerance of +/- .0015". The substantial economic benefit of this progress is the development of economical die-casting molds, which in many cases can extend project life and reduce the cost of zinc parts.

3,Miniature zinc parts circulate at a faster speed and are produced in a multi-slider hot-compartment_zinc_die_casting machine. These micro parts die casting machines have established this technology as the preferred process for complex micro zinc precision parts. Although high-precision miniature zinc die castings can be comparable to hot chamber zinc die castings for larger zinc parts, it can maintain tighter tolerances (usually zero draft) for "net shape" or "such as -cast" Fast cycle time.

4,Such miniature zinc parts are usually die cast with walls as thin as 0.020 inches (0.50 mm) and maintain tolerances of +/- 0.001 inches (0.03 mm).

The quality of zinc or ZA8 parts is improved by reducing metal shrinkage and eliminating post-die casting processing operations. Automated production of zinc parts can reduce the unit cost of miniature zinc parts to a few cents per penny with extremely low mold investment. And your miniature zinc and ZA-8 die-casting mold (tool) will last for the life of your project.

Benefits of zinc alloy

The zinc alloy used in die casting makes it possible to develop products and simplify production, thus providing durable products. The strength, stability and ductility of zinc allow experts to obtain a better and more durable final product. The high ductility of zinc makes it an ideal choice for die-casting processes. In the die-casting process, maintaining pressure and expanding without breaking is essential. Other benefits of zinc alloy are as follows.

Thermally and electrically conductive.

Strong stability, so that the final product has the highest quality finishing performance.

Zinc alloy helps improve corrosion resistance, especially in harsh environments, can improve its durability.

Zinc's low melting point means that it requires less energy to manufacture.

By using zinc in production, complex thin-walled and technically demanding components can also be manufactured with high precision.

Die castings are suitable for electroplating.
