Why Certifications Matter in Metal Finishing
Not all metal finishing companies are created equal. In industries where component performance is safety-critical, where tolerances are measured in microns, and where a single non-conformance can ground an aircraft or compromise a defense system, the credentials of your finishing supplier are not a formality. They are a fundamental part of your quality assurance process.
The Lindgren Group operates two certified metal finishing facilities in the Twin Cities metropolitan area, Avtec Finishing Systems in New Hope, MN and Nico Products in Minneapolis, MN. Both facilities hold the highest levels of accreditation available in the industry, giving our customers the confidence that every finish we apply meets or exceeds their most demanding specifications.
Nadcap Accreditation: The Gold Standard in Aerospace and Defense Finishing
Nadcap, the National Aerospace and Defense Contractors Accreditation Program, is the premier third-party accreditation program for special processes in the aerospace and defense industries. Unlike ISO certification, which evaluates quality management systems broadly, Nadcap accreditation is process-specific and technically rigorous. It evaluates not just whether a company has documented procedures, but whether those procedures are being executed correctly and consistently at the process level.
Earning and maintaining Nadcap accreditation requires passing detailed technical audits conducted by industry experts, demonstrating compliance with aerospace primes’ most stringent requirements, and committing to continuous improvement. It is one of the most demanding accreditations available in manufacturing, and it is required by many of the world’s leading aerospace and defense OEMs before they will approve a finishing supplier.
Both Avtec and Nico hold Nadcap accreditation for Chemical Processing and Aerospace Quality System, making The Lindgren Group one of the most comprehensively certified metal finishing companies in the region. If your supply chain requires Nadcap approved suppliers or Nadcap approved vendors, The Lindgren Group is ready to meet that requirement at both facilities.
ITAR Registration: Serving Defense Customers with Confidence
The International Traffic in Arms Regulations govern the export and import of defense-related articles and services on the United States Munitions List. For metal finishing companies working with defense contractors, ITAR registration is not optional. It is a legal requirement and a signal that the company has the controls, procedures, and corporate compliance infrastructure in place to handle sensitive defense work responsibly.
The Lindgren Group is ITAR registered and certified, with both Avtec and Nico fully compliant with the Arms Export Control Act and ITAR requirements. Our defense finishing capabilities include a wide range of coatings and plating processes used in military systems, weapons platforms, and defense electronics, all processed under the compliance framework that ITAR demands.
ISO 9001 Certification
ISO 9001 certification demonstrates that a company has implemented a documented, audited quality management system that consistently meets customer and regulatory requirements. Both Avtec Finishing Systems and Nico Products are ISO 9001 certified, providing an additional layer of quality assurance that complements our Nadcap accreditation and process-level controls.
For customers across industries including aerospace, electronics, medical, and OEM manufacturing, ISO 9001 certification means our quality management processes are independently verified and continuously maintained. You are not taking our word for it. You have the documentation to prove it.
Additional Certifications and Compliance
Federal Firearms License
Both Avtec and Nico hold a Federal Firearms License, allowing The Lindgren Group to engage in finishing work on firearms and related components in full compliance with the Gun Control Act of 1968. This capability supports customers in the defense and sporting industries who require a trusted, licensed finishing partner for firearm components.
RoHS and REACH Compliance
The Lindgren Group is fully compliant with RoHS and REACH requirements, limiting the use of hazardous substances and meeting European Union environmental regulations across our finishing processes. All of our finishes are available in RoHS compliant formulations, including matte tin, zinc, chromates, and cadmium-free lead-free electroless nickel.
CMMC 2.0 Certified
The Lindgren Group has achieved CMMC 2.0 certification, demonstrating our commitment to cybersecurity maturity and the protection of controlled unclassified information within our operations. For defense customers with CMMC requirements in their supply chain, The Lindgren Group is a fully compliant finishing partner.
