CNC milling of zinc alloy zinc die castings​

Introduction of Zinc Die Casting​

1. Compared with aluminum and magnesium alloys, zinc die castings are considered to be the easiest alloy to cast, which can generally extend the service life of tools.

2. Our zinc die-casting equipment includes hot chamber machines with lock-in pressure ranging from 250 tons to 500 tons. This manufacturing process allows us to produce high-quality parts in the final shape or close to the final shape specifications.

3. Zinc die castings are easy to process and can meet high precision requirements.

4. The characteristics of zinc alloy also make it an excellent choice for various surface treatments such as electroplating, conventional coating and powder coating.

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?

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

.
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.

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.

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.

Advantages of zinc die casting

Zinc alloys in die casting can develop products and simplify production to provide durable end products. The strength, ductility and stability of zinc allow experts to obtain better and more durable products. It is this high ductility that makes zinc ideal for die casting processes, in which pressure and expansion must be maintained without cracking. Other advantages of zinc alloy can also be used for die casting, such as:

Electrical conductivity and thermal conductivity

Low raw material cost

Strong stability, so that the lasting final product has high-quality finishing performance

Thin wall: They help improve the corrosion resistance of the final product and increase its durability in harsh environments

Small parts economy

Low melting point, which means less energy required for production

Longer mold life

Complex geometry and high-quality finishing: By using zinc, complex, thin-walled and technically demanding parts can be cast with high precision
High-quality coating and chrome plating: zinc die castings are suitable for electroplating
