Plating Methods Matched to Every Component Requirement

From complex and fragile parts to high-volume batches and selective surfaces, we apply the right plating method based on component geometry, production volume and finish requirements.

The Right Plating Method for Every Component

Different components require different approaches to achieve the required coverage and finish. At Smart Microns, we provide Rack Plating, Barrel Plating and Selective Plating for varying component sizes, geometries, volumes and functional requirements.

Our experienced team evaluates the component and required finish to determine the appropriate method, from custom racks for complex parts to rotating barrels for high-volume production and selective techniques for coating only specific areas.

Rack Plating

Precision Plating for Complex and Fragile Components

Rack plating is used for components that are large, fragile or geometrically complex and cannot be effectively processed through other methods. Each component is secured to a rack using metal hooks or bands before being immersed in the plating solution and exposed to an electrical current.

The fixed positioning of each part allows better control over the plated surface. Rack plating can also support selective or partial coating requirements. For components with complex geometries, auxiliary anodes or robbers may be used to help achieve the required coverage.

Our experienced team can engineer custom racks based on the component geometry and the finish required to meet demanding specifications.

  • Complex Components
  • Fragile Components
  • Large Components
  • Components Requiring Controlled Positioning
  • Selective or Partial Coating Requirements
  • Components with Demanding Finish Specifications
  • Aluminium
  • Steel
  • Stainless Steel
  • Nickel-Silver
  • Copper Alloys
  • Gold Plating
  • Silver Plating
  • Copper Plating
  • Bright Nickel Plating

Barrel Plating

Consistent Plating for High-Volume Components

In barrel plating, components are placed inside a barrel that rotates slowly while immersed in the plating solution. The rotation allows the parts to move continuously within the barrel, helping them receive consistent and uniform coating.

Electrical contact is established using danglers or centre bars positioned inside the barrel. This method is recommended for high-volume requirements and can accommodate a variety of component shapes, sizes and metals.

For larger or more fragile components, rack plating may be the more suitable option.

  • High-Volume Production
  • Small Components
  • Components with Similar Shapes and Sizes
  • Batch Plating Requirements
  • Components Requiring Consistent Coverage
  • Steel
  • Brass
  • Copper Alloys
  • Gold Plating
  • Silver Plating
  • Copper Plating
  • Bright Nickel Plating
  • Semi-Automatic Barrel Plating Line
  • Manual Barrel Plating Line

Selective Plating

Plating Only Where Performance Is Required

Selective plating deposits metal only on specific areas of a component while allowing the remaining surface to stay unplated. It is suitable for parts that require plating only in functional locations or have multiple zones with different coating or thickness requirements.

By avoiding unnecessary plating on non-functional areas, selective plating can help reduce precious-metal usage and associated costs.

  • Components with Specific Functional Areas
  • Parts Requiring Partial Plating
  • Components with Multiple Functional Zones
  • Areas Requiring Different Coating Thicknesses
  • Applications Requiring Reduced Precious-Metal Usage
  • Controlled Depth
  • Customised Fixtures and Jigs
  • Masking with Plater’s Tape
  • Masking with Chemical Lubricants

Choosing the Right Plating Method

Match the Method to the Requirement

Plating Method Best Suited For Key Advantage
Rack Plating Complex, fragile and larger components Controlled positioning and custom rack support
Barrel Plating High-volume batches of smaller components Consistent coating across multiple parts
Selective Plating Components requiring coating only in specific areas Reduced unnecessary plating and precious-metal usage
