As industries like aerospace, defense, and electronics push boundaries with lighter materials, smarter systems, and more demanding environments, the need for reliable, high-performance metal finishing has never been greater.

At The Lindgren Group, we partner with engineers and manufacturers building the next generation of technology—providing gold plating, hardcoat anodizing, zinc nickel plating, silver plating, tin plating, and connector plating designed to meet tomorrow’s standards, today.

The Role of Metal Finishing in Modern Manufacturing

Whether it’s an autonomous drone system, a satellite component, or an electric vehicle connector, modern parts are smaller, lighter, and more powerful—making the surface finish a critical performance factor.

Metal finishing directly affects:

  • Electrical signal quality
  • Structural durability
  • Resistance to corrosion and wear
  • Long-term reliability in unpredictable conditions

It’s no longer just about “finishing” a part—it’s about preparing it to succeed in a rapidly evolving world.

Metal Finishes That Support Emerging Technologies

Gold Plating

Used in aerospace, defense, and advanced electronics, gold plating supports ultra-reliable signal transfer and corrosion-free performance in:

  • RF and microwave connectors
  • Avionics and satellite systems
  • AI-driven robotics and sensors

It’s especially valuable in tight-tolerance, high-frequency components where downtime isn’t an option.

Hardcoat Anodizing

As aerospace and defense platforms adopt more aluminum to reduce weight, hardcoat anodizing is essential for protecting structural integrity.

  • Creates a durable oxide layer
  • Adds wear and abrasion resistance
  • Maintains low weight and high strength

Perfect for UAVs, electric aircraft parts, and lightweight defense gear.

Zinc Nickel Plating

Looking for a greener, more sustainable finish with top-tier corrosion resistance? Zinc nickel plating delivers:

  • Outstanding corrosion protection (over 1,000 hours salt spray)
  • RoHS-compliant and cadmium-free
  • Proven performance in automotive and aerospace systems

An ideal solution for companies prioritizing both durability and environmental responsibility.

Silver Plating

As EV and high-current electronics grow more powerful, silver plating is becoming the go-to for heat-sensitive, high-energy applications.

  • Unmatched thermal and electrical conductivity
  • Supports fast-charging systems and power grid infrastructure
  • Performs reliably at elevated temperatures

From grid connectors to spacecraft relays, silver is leading the charge in energy management.

Tin Plating

Still one of the most cost-effective and versatile finishes, tin plating remains essential in:

  • Consumer electronics
  • Automotive terminals
  • Mass-produced communications systems

Its solderability and resistance to oxidation make it a future-proof choice for scalable production.

Connector Plating

As systems grow more complex, reliable connector plating becomes a differentiator. We offer custom solutions using gold, silver, or tin to meet:

  • EMI/EMC requirements
  • Harsh environment standards
  • Micro-scale and high-density designs

Whether for aviation, military, or industrial automation—when failure isn’t an option, plating matters.
