Zinc Plating in High-Pressure Die Casting Treatments

Zinc Plating in High-Pressure Die Casting Treatments

The world of pressure casting, known in English as "High-Pressure Die Casting" or HPDC, is an industry that is constantly evolving, always seeking the best practices and treatments to improve the quality and durability of the parts produced. Zinc plating is one of this sector's most influential and widely adopted techniques. The Jegan company uses Zamak, an alloy of zinc with aluminium, magnesium, and copper, and applies this practice to its pieces.

Does HPDC stand for Zinc Plated?

Yes, HPDC stands for "High-Pressure Die Casting. In the High-Pressure Die Casting (HPDC) process for zamak, manufacturers inject molten zamak (a zinc alloy) into a mould under high pressure. This high pressure ensures that the material fills every intricate mould detail, producing detailed and precise castings. Many industries favour the HPDC method for zamak components due to its high production rates, outstanding dimensional accuracy, and smooth cast surfaces.

Zinc plating, sometimes called galvanising, is a process in which a protective layer of zinc is applied to metal parts to prevent rust and corrosion. Due to its more significant electrochemical activity than iron, Zinc acts as a sacrificial metal, offering cathodic protection to the underlying part.

Zinc-plated Zamak Pieces

The zinc plating process protects zamak parts, especially those used in aggressive environments or constant contact with corrosive agents. This additional layer can also improve the aesthetic appearance of the part, providing a shiny, uniform finish.

Benefits of Zinc Plating in HPDC

  • Protection against corrosion: Zinc plating offers a significant advantage in protecting against erosion. Zinc-plated Zamak parts last much longer in corrosive environments than untreated ones.
  • Improved Aesthetics: The zinc-plated finish gives the pieces a shiny and smooth appearance, which can be beneficial from an aesthetic and commercial point of view.
  • Wear resistance: The zinc plating process also improves the wear resistance of parts, which is crucial in components that experience friction or constant contact with other features.
  • Versatility: Different galvanising methods, such as electrolytic and hot-dip galvanising, allow companies to select the process that best suits their needs.

Sustainability-friendly technique or process

In the modern era, sustainability and environmental impact are critical considerations in any industry. Fortunately, zinc plating is a process that can be environmentally friendly. Contemporary zinc plating processes are designed for efficiency and produce minimal waste, as zinc is a natural element.

The zinc plating process for the parts of your industry

The zinc plating process in the context of High-Pressure Die Casting for zamak parts combines the strength and durability of zamak with the protective properties of zinc, offering high-quality parts that resist corrosion and wear. In a world where durability and longevity are essential, especially in industries such as automotive and construction, zinc plating is presented as an effective and sustainable solution. Companies that adopt and perfect this process invest in their products' quality and future in the market.
