In the world of advanced manufacturing, performance is measured in microns—and so is protection. At The Lindgren Group, we understand the pressure industries face to deliver durable, reliable, and high-performing products. That’s why we offer precision metal finishing services that enhance the strength, functionality, and lifespan of critical components.

Whether you need gold plating for a connector, hardcoat anodize for aerospace components, or zinc nickel plating for automotive durability, our finishes are engineered to perform where it matters most.

We Serve the Industries That Can’t Afford to Fail

Our finishes power innovation across some of the world’s most demanding sectors:

Aerospace

Aircraft and spacecraft components are exposed to high pressure, extreme temperatures, and critical safety requirements. We provide:

  • Hardcoat anodizing for abrasion-resistant aluminum components
  • Gold plating for precise, corrosion-free connections in avionics
  • Zinc nickel plating to protect landing gear and structural hardware

All finishes meet or exceed NADCAP and other aerospace standards.

Defense

In the defense world, strength, precision, and dependability are non-negotiable. Our defense coatings are trusted by military contractors for:

  • Hardcoat anodize on ruggedized gear
  • Connector plating using gold, silver, or tin to maintain high-performance signals
  • Zinc nickel plating as a durable, cadmium-free corrosion solution

Electronics & Communications

Flawless electrical performance starts with high-quality finishing. We serve electronics manufacturers with:

  • Gold plating for ultra-reliable signal transmission
  • Silver plating for high-frequency and high-voltage applications
  • Tin plating for economical conductivity with excellent solderability

Our connector plating processes are ideal for telecommunications, data centers, and precision electronics.

Automotive & Industrial Manufacturing

Parts that move, heat up, or face the elements need more than just strength—they need surface protection that lasts. We help auto and industrial manufacturers with:

  • Zinc nickel plating for undercarriage and engine parts
  • Silver plating for EV battery systems
  • Hardcoat anodizing for lightweight, high-durability aluminum

Our metal finishes reduce wear, prevent corrosion, and keep machines running longer.

Energy & Renewables

Energy infrastructure—especially in solar, wind, and storage systems—requires components that can withstand time, moisture, and temperature changes. We deliver:

  • Gold and silver plating for optimized conductivity
  • Zinc nickel plating for long-term outdoor corrosion protection
  • Connector plating for system stability and efficiency
