For manufacturers, OEMs, and engineering teams, choosing the right metal finishing partner can be just as important as selecting the right material or machining process. A properly specified finish can improve corrosion resistance, durability, conductivity, solderability, wear performance, and the service life of a component. For companies that are looking for experienced metal finishing and plating services in Minnesota, The Lindgren Group provides a broad range of finishing capabilities, backed by decades of industry experience, as well as NADCAP accreditation. 

 

Based in the Twin Cities, The Lindgren Group brings together Avtec Finishing Systems and Nico Products to provide manufacturers with access to extensive chemical, electroplating, anodizing, and mechanical finishing capabilities. Together, the facilities offer one of the most comprehensive selections of metal finishing processes available to manufacturers across the USA. 

 

A Broad Range Of Metal Finishing Capabilities 

Different components require different surface treatments. The ideal finish depends on the base material, operating environment, dimensional requirements, electrical properties, and applicable industry specifications. 

 

The Lindgren Group offers a variety of finishing options including the following:

 

  • Gold plating
  • Silver plating
  • Tin plating
  • Zinc and zinc nickel plating
  • Electroless nickel
  • Electrolytic nickel
  • Anodizing
  • Hardcoat anodizing
  • Passivation

 

As well as this, there are other conversion and mechanical finishing processes on offer. The company works with materials ranging from aluminum, stainless steel, steel, brass, and copper, all the way to specialty alloys including Inconel, Monel, and Hastelloy. 

 

The large breadth allows manufacturers to work with a single experienced finishing partner across multiple components and product lines. Whether the priority is corrosion protection, electrical conductivity, wear resistance, solderability, appearance, or other engineering requirements, The Lindgren Group can help identify and apply an appropriate finishing process to your components. 

 

NADCAP Accreditation For Quality Critical Manufacturing

For manufacturers serving demanding industries, quality systems and process control is more than essential, it’s imperative. NADCAP accreditation provides an important benchmark for companies that are looking for qualified suppliers for aerospace and other quality-critical applications. 

 

The Lindgren Group’s Avtec Finishing Systems and Nico Products operations maintain NADCAP accreditation, alongside ISO certification and other compliance necessities. NADCAP is focused on process control, though, and requires participating organizations to demonstrate that their processes are controlled, documented, and consistently managed to establish requirements. 

 

For customers, working with a NADAP accredited metal finisher can simplify supplier qualification and provide further confidence that finishing processes are being supported by established quality practices. The Lindgren Group combines these systems with experienced people, dedicated lab capabilities, and extensive production experience to create a rounded solution. 

 

Finishing For Power Supply And Bus Bar Applications

Metal finishing plays an especially important role in electrical power applications. Bus bars and related components often require finishes that support conductivity, corrosion resistance, long-term reliability, and connection performance. 

 

The Lindgren Group provides plating solutions for power supply and bus bar applications, including tin, silver, electroless nickel, electrolytic nickel, and copper plating. These finishes can be used on copper, brass, and other conductive components found in power distribution equipment, switch systems, networking equipment, communications infrastructure, power generation systems, and even military applications. 


Nico Products has also invested in dedicated tin plating capacity to support the ever expanding requirements of bus bar manufacturers and electrical equipment producers. The combination of specialized capabilities and process breadth provides manufacturers with another reason to consolidate finishing requirements with the same experienced supplier.
