When you’re building components for the aerospace, defense, or electronics industries, there’s zero room for failure. Every bolt, bracket, and circuit has to perform—no matter the conditions. That’s where The Lindgren Group comes in.

We specialize in high-performance metal finishing services like gold plating, hardcoat anodizing, zinc nickel plating, silver plating, tin plating, and connector plating—each designed to extend the life, reliability, and efficiency of your most critical parts.

So, Why Is Metal Finishing Such a Big Deal?

Metal isn’t invincible. Without a protective finish, it can corrode, wear down, or even short-circuit electrical systems. But with the right finish? You’ve got a high-performing part that lasts longer and works better.

Here’s what the right metal finish brings to the table:

  • Protection against rust, corrosion, and environmental damage

  • Increased durability in high-friction, high-wear settings

  • Enhanced conductivity for flawless electronic connections

  • Improved aesthetics for consumer-facing or visible components

Where Our Metal Finishing Makes an Impact

✈️ Aerospace

From cabin systems to cockpit electronics, aerospace components must perform at 30,000 feet and beyond.

Our aerospace coatings are designed for durability and compliance with industry standards like NADCAP.

Most-used finishes:

  • Gold plating for mission-critical electronic connectors

  • Hardcoat anodize for strong, lightweight aluminum parts

  • Zinc nickel plating for next-level corrosion protection

🛡️ Defense

Military-grade hardware must survive extreme environments—desert heat, ocean salt, and everything in between. Our defense coatings are built for the battlefield.

Popular choices:

  • Zinc nickel plating for rugged, corrosion-resistant parts

  • Hardcoat anodizing for weapon systems and tactical gear

  • Connector plating to maintain flawless communication in the field

🔌 Electronics & Connector Plating

Precision is everything in electronics. Just one faulty connection can derail an entire system. We provide connector plating services that ensure stable, long-term electrical contact.

Our go-to solutions:

  • Gold plating for unbeatable conductivity

  • Silver plating for high-current and RF applications

  • Tin plating for reliable, budget-conscious conductivity

🚗 Automotive & Industrial

From engine components to electric vehicle terminals, we support automotive and industrial manufacturers with coatings that go the distance.

Popular finishes:

  • Zinc nickel plating for corrosion-prone undercarriage and engine parts

  • Hardcoat anodizing for strength without added weight

  • Silver plating for energy-efficient electrical systems

☀️ Renewable Energy

Solar panels. Wind turbines. Battery banks. These components live outside and work hard, which means they need extra protection.

Best fit finishes:

  • Silver plating for high-conductivity applications

  • Zinc nickel plating to resist the elements

  • Gold plating for performance-critical connectors
