Zinc Die Casting

Zinc Alloy Die Casting

What Is Zinc Alloy Die Casting – Define Of Zamak Die Casting

Zinc alloy die casting is a kind of pressure die casting parts. It is a mechanical die-casting machine equipped with a casting mold. The zinc or zinc alloy heated to a liquid state is poured into the feeding port of the die-casting machine. Zinc parts or zinc alloy parts that limit the shape and size of the mold, such parts are often called zinc alloy die castings.

The material of zinc alloy is zinc-aluminum alloy, which are active amphoteric metals. Commonly used zinc alloy materials in industry contain about 4% of Al, 0.75% to 1.25% of Cu, 0.03% to 0.08% of Mg, and the rest are the main components. Zn, Zn is an amphoteric metal. The electrode potential is relatively negative, and it is sensitive to acid and alkali, and is prone to chemical reactions leading to corrosion. Moreover, during the die-casting process of zinc alloy materials, component segregation often occurs due to the temperature difference on the surface of the workpiece, and zinc-rich or aluminum-rich phases appear locally on the surface. The aluminum phase or zinc-rich phase dissolves preferentially, and the uneven corrosion of the surface leads to the generation of pore pitting and even bubbles, which affects the surface quality. The organizational structure of zinc alloy die-casting materials has its particularity, that is, its die-casting surface is dense and smooth, with low porosity, low hardness and a thin surface dense layer, generally only 0.05~0.2mm. The inner layer is porous and loose structure.

Why Often Using Zinc For Die Casting Material?

Zinc alloy is an alloy composed of other elements based on zinc. The alloying elements that are often added are aluminum, copper, magnesium, cadmium, lead, and titanium. Zinc alloy has low melting point, good fluidity, easy fusion welding, brazing and plastic processing, corrosion resistance in the atmosphere, easy recycling and remelting of residual waste, but low creep strength, prone to dimensional changes caused by natural aging. Prepared by melting, die casting or pressure machining.Die Cast Zinc Alloy has good fluidity and corrosion resistance, and is suitable for die-casting instruments, automobile parts shells, accessories, etc. His advantages are as follows:

  1. Specific Gravity
  2. Good Casting Performance, It can die-cast precision parts with complex shapes and thin walls, and the surface of the castings is smooth.
  3. Surface Treatment Is Available: Electroplating, spraying, painting, polishing, grinding, etc.
  4. It Does Not Absorb Iron During Melting And Die Casting, Does not corrode the molding, and does not stick to the mold.
  5. It Has Good Mechanical Properties And Wear Resistance at room temperature.
  6. Low Melting Point, Melting at 385℃, Easy to die-cast.

What Are Often Using Grades Of Zinc Die Casting?

Pintejin expert engineers are experienced in working with different grades of zinc alloy material to cater to zinc die casting needs. The traditional die-casting zinc alloys are No. 2, 3, 4, 5, and 7 alloys, and the most widely used is No. 3 zinc alloy. In the 1970s, high-aluminum zinc-based alloys ZA-8, ZA-12, and ZA-27 were developed.

  • Zamak 3: Good flow and mechanical properties. It is used in castings that do not require high mechanical strength, such as toys, lamps, decorations, and some electrical devices.
  • Zamak 5: Good flow and good mechanical properties. It is used in castings that have certain requirements on mechanical strength, such as auto parts, electromechanical parts, mechanical parts, and electrical components.
  • Zamak 2: Used for mechanical parts that have special requirements for mechanical properties, high hardness, good wear resistance and general dimensional accuracy.
  • ZA8: Good impact strength and dimensional stability, but poor flow. It is used for workpieces with small size, high precision and mechanical strength, such as electrical components.
  • Superloy: The best fluidity, suitable for die-casting thin-walled, large-sized, high-precision, complex-shaped workpieces, such as electrical components and their boxes.
