In industries where failure is not an option—aerospace, defense, electronics, and industrial manufacturing—metal finishing isn’t just a detail, it’s a defining factor in performance and reliability.

At The Lindgren Group, we provide advanced surface finishing solutions like gold plating, hardcoat anodize, zinc nickel plating, silver plating, tin plating, and connector plating that help critical components endure, connect, and excel.

What We Do: More Than a Finish

A raw metal part might meet dimensional specs—but without a protective finish, it’s vulnerable. Metal finishing solves real-world problems like corrosion, conductivity loss, and mechanical wear.

Our metal finishing services enhance:

  • Durability in high-friction or high-heat environments

  • Corrosion resistance against water, chemicals, and air exposure

  • Electrical performance for precise, uninterrupted signal flow

  • Product lifespan, reducing costly downtime and replacements

From aerospace electronics to automotive systems, we finish what others start—and make it last.

Industries That Trust The Lindgren Group

Aerospace: Built for Altitude

When you’re dealing with 500 mph flights and fluctuating pressure, components have to perform. Our aerospace coatings are engineered to meet strict requirements, from weight reduction to conductivity.

  • Hardcoat anodizing protects aluminum components from wear and corrosion

  • Gold plating ensures reliability in high-frequency connectors

  • Zinc nickel plating shields surfaces from oxidation, even in extreme climates

Defense: Battle-Tested Finishes

Military-grade parts don’t get second chances. Our defense metal finishing services provide rugged protection and high functionality for mission-critical equipment.

  • Connector plating ensures seamless electrical communication

  • Hardcoat anodize offers extreme abrasion resistance

  • Silver and zinc nickel plating provide corrosion resistance in land, air, and sea environments

Electronics: Reliable, Repeatable Performance

Whether it’s a commercial data center or satellite system, electronics demand consistent, clean electrical connections. We specialize in connector plating that ensures your systems work every time.

  • Gold plating for low-resistance, corrosion-proof signal flow

  • Silver plating for high-amperage and RF applications

  • Tin plating for a cost-effective solution with solid solderability

Automotive & Industrial: Designed for the Long Haul

Today’s vehicles and heavy machinery must perform longer and more efficiently. Our finishes reduce friction, extend part life, and defend against the elements.

  • Zinc nickel plating is ideal for engine components and structural steel

  • Hardcoat anodizing strengthens lightweight parts without adding mass

  • Silver plating improves performance in high-power electric vehicles

Renewable Energy: Protecting Power in Motion

Solar farms. Wind turbines. Energy storage banks. These systems rely on long-lasting, corrosion-resistant connections—especially in outdoor conditions.

  • Gold and silver plating optimize current transfer

  • Zinc nickel protects hardware from rust and salt exposure

  • Connector plating ensures reliable, long-term operation
