In high-performance industries, off-the-shelf solutions rarely cut it. Your components have specific requirements. Your clients have strict timelines. And your industry has non-negotiable standards. That’s why engineers, manufacturers, and buyers turn to The Lindgren Group—a metal finishing partner that doesn’t just check the box, but customizes the solution.

From gold plating and hardcoat anodizing to zinc nickel plating, silver plating, tin plating, and connector plating, our processes are designed not only to protect and enhance—but to solve real-world problems.

When One-Size-Fits-All Fails, Custom Finishing Wins

Every part has a job to do—and the finish you choose has a direct impact on whether it performs, for how long, and under what conditions. At The Lindgren Group, we help companies across industries answer key questions:

  • Will this finish withstand corrosion in outdoor or marine environments?
  • Is it conductive enough for high-frequency signal transmission?
  • Can it hold up to extreme wear, vibration, or temperature swings?
  • Is it RoHS, NADCAP, or MIL-SPEC compliant?
  • Can we finish thousands of parts—fast and accurately?

If you’ve got a spec sheet or a headache, chances are we’ve seen it before—and solved it.
