Which is better between hardware electrophoretic processing technology and electroplating technology

Which is better between hardware electrophoresis processing technology and electroplating technology? Introduce and compare their corrosion resistance, wear resistance, appearance, and other aspects. Let's take a look together!

In terms of corrosion resistance: Whether it is metal electrophoretic processing or electroplated products, their corrosion resistance mainly depends on what is "electroplated"? The corrosion resistance of epoxy electrophoresis products can be tested for over 1000 hours in neutral salt spray test, but acrylic acid and polyurethane electrophoresis may only last for a few tens of hours. Similarly, the salt spray test time for galvanized nickel alloy products can reach thousands of hours, but during galvanizing, it may only take a few tens of hours.

In terms of wear resistance, as mentioned above, hardware electrophoretic processing is an organic coating, and the coating is a metal or alloy. As we can understand from simple common sense, at least the coating is just a metal that directly appears in terms of abrasion resistance. So, electroplated coatings are often superior to electrophoretic coatings! The products with high wear resistance that we see in daily life are electroplated products such as bearings.

In terms of appearance: This cannot be concluded. However, in terms of color, hardware electrophoretic processing products are much more diverse than electroplating. In theory, electrophoresis can be any color. Therefore, most of the jewelry nowadays undergoes electrophoresis after electroplating to present rich colors and increase its ranking. However, in terms of metallic texture and luster, electrophoresis is difficult to achieve the metallic appearance of coatings.

Regarding the integrity of the coating, due to the excellent electrophoretic transparency of hardware electrophoretic processing, especially epoxy electrophoresis, good coatings can also be obtained in the concave parts, gaps, inner cavities, and other areas of the workpiece; Electroplating is directly affected by high and low potentials, and it is difficult to compare the integrity and uniformity of electroplating with electrophoresis for workpieces with complex shapes and deep hole structures.

In terms of cost: Metal electrophoretic processing is generally lower than electroplating, especially for products with high corrosion resistance.

In terms of environmental protection, this is an issue that cannot be ignored in the field of surface treatment today. Metal electrophoretic processing paint uses water as the solvent, does not contain heavy metals, and has a low organic solvent content (generally around 2%). The effective recovery rate of the paint can reach over 95%, with low emissions and light environmental pollution. Electroplating solutions often contain various heavy metal ions such as chromium, cadmium, nickel, silver, etc., which can easily cause pollution. If accidentally leaked, it can seriously affect the environment!

The above introduction is about which is better between hardware electrophoresis processing technology and electroplating technology. Both hardware electrophoresis processing technology and electroplating technology have their own strengths, and they cannot completely replace each other! It is important to consider the usage requirements of the product. If the performance electrophoresis of the product is satisfactory, it is recommended to prioritize electrophoresis. For example, the guide rail used to be galvanized, but now it is generally replaced by electrophoresis.
