Plating Functions
Why We Plate
The primary purpose of plating is to improve the surface characteristics of a material to meet specific performance requirements. Functional plating plays a critical role in many industries by providing enhanced durability, reliability, and environmental resistance.
Corrosion Resistance
Plating helps prevent rust, oxidation, and chemical degradation of base materials. Mitsuya’s electroless nickel plating with high phosphorus content and nickel-iron (Ni-Fe) plating offer excellent corrosion protection in harsh chemical and marine environments.
Electrical Conductivity
In the electronics industry, plating improves electrical conductivity of components such as connectors, lead frames, and semiconductor parts. Mitsuya’s silver and electrolytic gold platings provide superior conductivity and low contact resistance, ensuring stable signal transmission in high-performance electronics.
Wear and Abrasion Resistance
Functional plating enhances the durability of parts subject to repeated friction, contact, or mechanical stress. Mitsuya’s electroless nickel plating with controlled phosphorus content offers outstanding wear resistance and hardness suitable for automotive and mechanical components.
Solderability and Adhesion
Certain plating finishes promote strong bonding with solder or adhesives. Mitsuya’s palladium-nickel (Pd-Ni) alloy and gold-tin (AuSn) alloy platings improve solderability for reliable connections in printed circuit boards and electronic assemblies.
Heat and Chemical Resistance
Plating provides a protective barrier against extreme temperatures and aggressive chemicals. Mitsuya’s chrome and specialized heat-resistant silver platings are used in demanding environments such as aerospace and industrial machinery.
Light Absorption and Reflection Control
Functional coatings can be tailored to either absorb or reflect light as needed. Mitsuya’s proprietary Black Arrow plating delivers low reflectivity for aerospace components requiring minimal glare. In contrast, highly reflective gold plating is applied for specialized uses such as interior plating of pipes and reflective surfaces in laser and optical devices, where maximum reflectivity is critical.
While Mitsuya does not engage in decorative plating, our focus on high-performance, functional surface treatments tailored to industrial needs helps customers achieve consistent quality, improved product performance, and higher reliability in demanding applications.
