Surface Treatment Methods of Automotive Forging Parts

Automotive forging parts often need surface treatment to improve their corrosion resistance, decorative properties, and mechanical properties. Here are several commonly used surface treatment methods for automotive forging parts, along with actual production examples.

  1. Coating treatment Coating treatment involves coating the surface of a forging part with a layer of metal or non-metallic material to prevent oxidation or improve its appearance. Electroplating, hot-dip plating, and spraying can all be used to achieve coating treatment on forging parts. Electroplating is one of the most common methods, which adds chrome, nickel, zinc, cadmium, and other metals to the whole surface of the forging part, increasing its corrosion resistance and aesthetics. For example, in car manufacturing, stainless steel electroplating is often used to make dashboard panels, which are beautiful, durable, and easy to clean.
  2. Coating treatment Coating treatment involves applying special chemical coatings to the surface of forging parts to change their surface state. For instance, epoxy resin coating can strengthen the mechanical strength, hardness, and corrosion resistance of forging parts. A certain car company introduced a hydraulic toy car wheel hub production line with independent intellectual property rights, which uses an efficient spraying production automatic line to provide surface coating for the wheels to make them more durable and beautiful.
  3. Sandblasting treatment Sandblasting changes the surface state of forging parts by blasting aluminum silica sand dust, etc. abrasives onto them. This method can enhance the surface hardness of forging parts and provide better anti-corrosion properties, such as reducing surface roughness and initial crack numbers. For example, in a certain automobile engine cylinder body manufacturing production line, sandblasting is frequently used before casting to increase its density and mechanical strength.
  4. Polishing treatment Polishing gradually makes the surface of forging parts glossy and bright by applying different grades of abrasive materials. This method can remove scratches, dirt, etc. on the surface of forging parts and enhance their corrosion resistance. For example, after polishing automotive brand body shells, they exhibit a perfect detailed appearance and vibrant colors.

In conclusion, surface treatment for automotive forging parts can improve their aesthetics, corrosion resistance, and mechanical strength. Different treatment methods can maintain good detailed appearance and stable performance of forging parts to give consumers peace of mind when using them.
