IGSINK specializes in advanced aluminum heat sink anodizing and copper heat sink anodizing processes, delivering superior thermal performance, enhanced durability, and exceptional corrosion resistance for your critical applications.
Advanced surface treatment technology for optimal thermal management performance
Anodizing increases surface emissivity from 0.05 to 0.85, dramatically improving radiative heat transfer and overall cooling efficiency.
Creates a protective aluminum oxide layer that resists atmospheric corrosion, moisture, and chemical exposure for extended service life.
Aluminum oxide provides excellent electrical insulation, preventing short circuits and improving system safety and reliability.
Hard anodized surface provides exceptional wear resistance and protection against scratches, extending component lifespan.
Available in multiple colors including black, blue, red, and clear finishes for branding and visual identification requirements.
Environmentally friendly process that adds minimal cost while delivering significant performance and protection benefits.
Advanced electrochemical treatment for aluminum and copper heat sinks
Thorough cleaning and degreasing to remove contaminants and ensure optimal adhesion of the anodic layer.
Immersion in sulfuric acid electrolyte solution under controlled temperature and concentration conditions.
Direct current application creates controlled aluminum oxide layer growth with precise thickness control.
Optional dye application followed by sealing process to lock in color and create non-porous protective surface.
Specialized cleaning process to remove copper oxides and prepare surface for anodizing treatment.
Controlled chemical treatment to create uniform copper oxide layer with enhanced thermal properties.
Application of protective coating to prevent further oxidation while maintaining thermal conductivity.
Comprehensive testing for thickness, adhesion, and thermal performance to ensure specification compliance.
Precise control parameters for optimal anodizing results
