Surface finishing

At Leading Edge, we provide comprehensive surface finishing services that enhance the functionality, durability, and aesthetic appeal of your machined parts. With a wide array of finishing options, we ensure that your components meet exact specifications and industry standards.

Finishing

Our surface finishing options

Surface finishing refers to processes applied to the exterior of a machined part to improve its appearance, performance, or durability. Whether you need corrosion resistance, wear protection, or a polished look, our advanced techniques deliver superior results tailored to your application.

Anodizing enhances the surface of aluminum parts by creating a durable, corrosion-resistant oxide layer. Available in various colors, anodizing also improves wear resistance and adds a professional finish.

  • Applications: Electronics enclosures, aerospace components, decorative hardware.
  • Benefits: Corrosion resistance, wear resistance, vibrant color options, electrical insulation.
  • Types:
    • Type II: Standard anodizing for decorative and corrosion-resistant finishes.
    • Type III (Hard Anodizing): Thicker, more durable layer for high-wear applications.

Powder coating involves applying a dry powder to a part’s surface and curing it under heat to form a hard, durable finish. This method offers excellent adhesion and is available in various colors and textures.

  • Applications: Automotive parts, industrial equipment, consumer products.
  • Benefits: High durability, vibrant color options, resistance to chipping and peeling.
  • Capabilities:
    • Smooth, textured, or matte finishes.
    • Thickness range: 40–100 microns for optimal coverage and protection.

Electroplating uses an electric current to deposit a thin metal layer onto a part’s surface, enhancing conductivity, corrosion resistance, and aesthetic appeal.

  • Applications: Electrical contacts, decorative hardware, medical components.
  • Benefits: Enhanced corrosion resistance, improved electrical conductivity, superior aesthetic finishes.
  • Common Materials: Gold, silver, nickel, chrome, and zinc.

Polishing creates a smooth, reflective surface by removing imperfections. This finish is ideal for parts requiring an aesthetic appeal or low friction.

  • Applications: Medical implants, optical components, consumer products.
  • Benefits: Mirror-like finish, reduced friction, enhanced aesthetics.
  • Techniques:
    • Mechanical polishing for high precision.
    • Electro-polishing for hard-to-reach areas and enhanced corrosion resistance.

Bead blasting uses pressurized air to propel abrasive particles against the surface, creating a uniform matte texture and removing surface imperfections.

  • Applications: Aerospace parts, consumer electronics, decorative finishes.
  • Benefits: Uniform texture, removal of impurities, improved coating adhesion.
  • Media Options: Glass beads, aluminum oxide, and silicon carbide for tailored finishes.

Passivation is a chemical process that enhances the corrosion resistance of stainless steel by removing contaminants and forming a protective oxide layer.

  • Applications: Medical devices, food processing equipment, aerospace components.
  • Benefits: Enhanced corrosion resistance, extended part longevity, and reduced maintenance.
  • Standards: Compliance with ASTM A967 and ISO standards for critical applications.

Custom painting services provide vibrant colors, protective coatings, and custom textures to meet unique design and branding requirements.

  • Applications: Consumer electronics, automotive parts, industrial machinery.
  • Benefits: Aesthetic appeal, weather resistance, and branding customization.
  • Capabilities:
    • Multi-coat systems for durability.
    • Precision masking for detailed designs.

Brushing gives parts a textured, satin-like appearance, combining aesthetics with improved surface uniformity.

  • Applications: Decorative hardware, appliances, consumer electronics.
  • Benefits: Professional look, scratch resistance, and enhanced grip.
  • Capabilities:
    • Fine to coarse texture options.
    • Custom patterns, including straight-line or cross-hatch brushing.
