Electronic components and bracket

Anodizing & Conversion

Anodizing (Type II - Cosmetic):

  • Features: Adds corrosion resistance and allows for custom color dyeing (Black, Red, Blue, Gold, etc.).
  • Ideal for: AL 6061-T6 E-cigarette caps, 3C consumer electronics housings.

Hardcoat Anodizing (Type III):

  • Features: Creates an extremely hard, wear-resistant surface.
  • Ideal for: Aerospace components, heavy-duty automotive parts.

Chemical Conversion Coating / Alodine:

  • Features: Retains electrical conductivity while protecting against corrosion.
  • Ideal for: EMI/RFI shielding in electronic enclosures.

Mechanical Finishes

Standard (As-Milled / As-Turned) :

  • Features: Standard Ra 1.6µm (63 µin) or finer. Precision tool marks may be visible.
  • Ideal for: Internal structural parts, hidden automotive components.

Bead Blasting:

  • Features: Removes tool marks, creating a uniform, matte, non-reflective texture. Often combined with anodizing.
  • Ideal for: Medical equipment handles, visible aluminum brackets.

Polishing:

  • Features: Reduces surface roughness to a mirror-like finish.
  • Ideal for: Pure Titanium Watch Cores , surgical tools.

Advanced Deburring & Precision Finishing

Precision Lapping:

  • Features: Achieves extreme flatness and ultra-fine surface roughness (Ra 0.1µm - 0.4µm) without compromising tight dimensional tolerances.
  • Ideal for: Valve seats, mechanical seals, fluid control components, and precision medical instruments.

Vibratory Tumbling:

  • Features: Efficient mass deburring and edge rounding. Creates a uniform, non-directional matte finish.
  • Ideal for: High-volume turned parts, structural aluminum brackets.

Magnetic Polishing:

  • Features: Utilizes magnetic fields and micro-pins to deburr complex internal cavities, blind holes, and threads without altering precise external dimensions.
  • Ideal for: Complex Swiss-machined micro-parts, internal RF cavities, medical instruments.
