High Strength Corrosion Resistant Polished Zinc Die Casting

Corrosion Resistant Polished Zinc Die Casting

Zinc die casting

Zinc Die Casting Zinc is one of the most widely used parts in die casting alloys. It has high accuracy and low mold cost. Zinc die casting has a wide range of interests and can be used in different places due to its amazing display and quality.

Zinc die casting parameters

Advantage:

1. The relative weight of zinc die castings is more significant.

2. Zinc die-cast precision parts have complex shapes, more slender dividing lines and smooth surfaces.

3. Zinc die casting parts have high precision, high mechanical quality, reflectivity and conservative surface. Little or no chipping occurs during processing.

4. There are some surface treatment agents for zinc die castings: electroplating, spraying, painting, cleaning, beating, etc.

5. Zinc alloy has no iron assimilation, no contour corrosion, and no shape adhesion during softening and casting.

6. Zinc die-casting parts have excellent mechanical properties and scraping area execution ability.The low melting point of about 385°C makes the forming of zinc alloy die castings simple.

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.
