metal electrical parts coatings services

Electroplating is a process that applies a thin metallic coating onto a conductive material using an electric current. It enhances properties such as corrosion resistance, conductivity, and wear resistance. The metal component is submerged in an electrolyte solution containing dissolved metal ions, and an electrical current is used to deposit the coating onto the surface.

At Electris, we specialize in electroplating copper and aluminum components, but electroplating procesess involves applying coatings to various metals, with the specific coating type selected based on the desired characteristics of the final component.

The duration of electroplating depends on several factors, including the size of the component, type of coating, and required thickness. Generally, the process can take anywhere from a few minutes to several hours.

The most frequently used coatings include:

• Tin plating – Offers excellent corrosion resistance, good conductivity, and solderability.

• Nickel plating – Enhances hardness, oxidation resistance, and wear protection, improves thermal conductivity and increases the component's resistance to high temperatures .

• Silver plating – Provides superior conductivity and corrosion resistance, commonly used in electrical applications.

• Corrosion resistance – Protects metal surfaces from oxidation and environmental damage.
• Enhanced conductivity – Important for electrical and energy applications, for exemple: silvering process
• Improved wear resistance – Increases durability and lifespan of components.
• Solderability – Essential for electrical connectors and PCB components.
• Aesthetic and functional coatings – Provides a smooth, uniform finish.

Yes, electroplating significantly improves corrosion resistance by creating a protective barrier between the base metal and external elements. This prevents oxidation, extending the component's service life.

• Surface preparation – Cleaning and degreasing to remove impurities.
• Degreasing – the elimination of fats and oils, which could weaken the coating's adhesion.
• Etching and pickling – removing the oxide layer to ensure good adhesion of the coating metal.
• Electroplating – Immersing the component in a solution and applying an electric current.
• Post-treatment – Rinsing, drying, and quality control.

Electroplating does not weaken the base material. Instead, it enhances durability by providing a wear-resistant and corrosion-resistant layer. Nickel and silver coatings, for example, improve hardness and lifespan.

Yes, surface preparation is crucial for a high-quality coating. The metal must be cleaned, degreased, and sometimes etched to ensure proper adhesion of the electroplated layer.

At Electris, we focus on sustainable electroplating by utilizing a closed-loop wastewater treatment system, heat recovery technology, and environmentally friendly coatings. Our processes comply with EcoVadis certification standards.

Electroplating is widely used in industries such as:

• Energy & power – conductive,corrosion-resistant, and  improve metal hardness and wear resistancecoatings for bus bars, connectors, and electrical components.
• Electronics – PCB coatings, connectors, and switch components.
• Industrial machinery – Wear-resistant coatings for metal parts.
• Automotive – Protective and decorative coatings for metal parts.
• Aerospace – Lightweight, durable coatings for aircraft components.

The cost of electroplating depends on:

• Type of base metal
• Coating material (tin, nickel, silver, etc.)
• Component size and complexity
• Required coating thickness
• Batch size and production volume
