I am looking for a metal finishing shop that specializes in anodizing aluminum parts.

Since you’re around the Orlando/Holden Heights area, I found several good candidates. The strongest match is Elite Metal Finishing East:

• Elite Metal Finishing East, llc. — 7594 Chancellor Dr, Orlando, FL 32809 · 407-843-0182. They specifically offer Type II anodizing and Type III hardcoat anodizing, including MIL-spec work, masking, testing, and large-part processing. Their tanks can handle parts up to about 16 ft.
• Peninsula Metal Finishing Inc — 2550 Dinneen Ave, Orlando, FL 32804 · 407-291-1023. A local production metal-finishing shop with anodizing among its services; customer feedback specifically mentions Type II anodizing.
• David Russell Anodizing — 2501 McCracken Rd, Sanford, FL 32771 · 407-302-4041. More specialized toward aluminum anodizing, including Type II, Type III hardcoat, bright/satin finishes, and color anodizing.
• Florida Anodize System & Technologies Inc. — 60 Keyes Ct, Sanford, FL 32773 · 407-302-3278. Another dedicated anodizing operation, particularly suited to precision/specification-driven aluminum work.
• Orlando Plating Co Inc — 601 N Orange Blossom Trl, Orlando, FL 32805 · 407-592-6534. Local metal-finishing provider; I'd call first to confirm the exact anodizing process they currently accept.

My first call would be Elite Metal Finishing East, especially if these are machined aluminum parts and you need a particular specification such as MIL-A-8625 / MIL-PRF-8625 Type II or Type III. They also appear well equipped for commercial, industrial, aerospace, and defense work.

If you tell me (1) approximate part size, (2) aluminum alloy, (3) Type II vs. hardcoat Type III, (4) color, and (5) quantity, I can narrow this down to the 2–3 shops most appropriate for your specific parts and look for pricing/turnaround information.

Finding the right metal finishing shop depends on your location, volume, and specific anodizing requirements (such as Type II sulfuric, Type III hardcoat, or cosmetic color dyeing).

Several well-established, reputable metal finishing companies across the U.S. specialize in aluminum anodizing:

1. • Pioneer Metal Finishing - One of the largest non-captive metal finishers in North America, offering large-scale commercial, hard coat, and bright dip anodizing across multiple regional US facilities.
2. • Anoplate - A major nationwide metal finisher providing a full spectrum of aluminum processes, including hardcoat anodize, sulfuric anodize, and chromic acid anodize.
3. • US Anodize - Specializes in custom MIL-PRF-8625 Type II and Type III sulfuric anodizing with high-volume capabilities and extensive color-dyeing options.
4. • Certified Metal Finishing (CMF) - Based in Florida and trusted for mission-critical, high-precision aerospace, defense, and medical aluminum anodizing.
5. • Luke Engineering and Anodizing - Located in Ohio, specializing in Type II and Type III hardcoat anodizing with NADCAP and ISO 9001 certifications.
6. • SendCutSend - A popular choice for digital manufacturing and rapid turnaround Type II aluminum anodizing for smaller or prototype runs.

To narrow down a local or specialized shop, you can also search the official Aluminum Anodizers Council Member Directory.

If you'd like to narrow this down, please let me know:

• Your geographic location or preferred shipping radius
• The type of anodizing you need (Type II cosmetic/clear/color vs. Type III hardcoat)
• Estimated part size and volume (prototype run vs. high-volume production)

I can give you a more tailored recommendation.

Yes. Since you’re in the Passaic area, there are several good options nearby that specifically handle aluminum anodizing rather than just general metal finishing.

Best nearby options

• TRB-ANDARN — Paterson, NJ
  Very close to Passaic. Offers Type I chromic, Type II sulfuric, and Type III hardcoat anodizing and works with production/custom industrial parts. Their site also emphasizes specification-driven finishing and testing.

• Aerotech Processing — Paterson, NJ
  Particularly worth considering for aerospace, defense, or high-specification parts. They offer Type I, II and III anodizing, including hardcoat, and are NADCAP-certified.

• Master Metal Finishers — Paterson, NJ
  Offers sulfuric, chromic, and hardcoat anodizing, including clear and dyed finishes. A convenient local option if you need multiple finishing processes.

• Miller & Son — Belleville, NJ
  Established metal-finishing shop offering hardcoat, sulfuric, chromic and colored anodizing, along with masking, inspection/certification, and other finishing processes. They specifically advertise both small lots and high-volume work.

• B & M Finishers Inc — Kenilworth, NJ
  A particularly strong choice for industrial/aerospace-quality aluminum parts. They specialize in aluminum anodizing and offer Type I, Type II and Type III/hardcoat processes. They are NADCAP-certified and AS9100 registered.

• Paramount Metal Finishing Co — Linden, NJ
  Offers MIL-A-8625 Type II and Type III anodizing, including clear, dyed and hardcoat finishes. They also have NADCAP accreditation for their anodizing processes.

My shortlist

If I were choosing based on your location, I'd start with:

1. TRB-ANDARN — closest and highly focused on metal finishing.
2. Aerotech Processing — especially if the parts have aerospace/defense specifications.
3. B&M Finishers — excellent candidate for recurring production work and specification-controlled anodizing.
4. Miller & Son — good choice for smaller lots or a broad range of finishing requirements.

If you tell me what type of aluminum parts you have, approximate part size, quantity, desired finish (clear/black/color/hardcoat), and whether you need a MIL/AMS specification, I can narrow this down to the 2–3 shops most likely to be a good fit and find their contact/quote information.
