Process Overview
Tin Plating
Tin plating provides a reliable, solderable coating with good corrosion resistance. It is widely used in electrical, automotive, and general engineering applications. We offer rack (bath) tin for larger or precision components and barrel tin for high-volume small parts, ensuring consistent coverage and functional performance as per application needs.
Coating Thickness
Electrical / connectors
2 – 5 µm

Available Types
Types of Tin Plating
Bath Tin
Rack-plated tin suitable for larger components and parts requiring better thickness control and surface finish. Commonly used for electrical components, connectors, and fabricated parts.
Barrel Tin
Tin plating done in a rotating barrel, ideal for small, high-volume parts such as fasteners, terminals, and stampings. Provides uniform coating and cost-effective processing.
Why It Works
Key Advantages
- Good corrosion resistance in mild environments
- Improved solderability for electrical applications
