Machine shops specialize in producing machined parts and components and support various industries. Aerospace, Automotive, OEM, Defense, Medical, Agriculture, and Electronics are just a few industries supported by many machine shops. In turn, Avtec Finishing Systems and Nico Products support their efforts, offering dozens of metal finishing options, with processes meeting exacting standards required by each industry.

Our Nadcap and ISO Certifications, ITAR, RoHS, and Reach Compliance make certain these customers meet the end-user requirements for their parts. Specializing in high-volume production, we are well-suited for your large projects.

Metal coatings commonly used in machine shop applications include:

• Anodized Coatings
• Hardcoat Anodize
• Chromate Conversion
• Zinc and Zinc Nickel
• Electroless Nickel
• Electrolytic Nickel
• Electropolishing
• Passivation
• Gold and Silver Plating
• Tin
• More…

The Lindgren Group: Avtec Finishing Systems and Nico Products work with many machine shops and companies with machining processes to provide superior-quality metal coatings and plating for numerous applications. Work with our Business Development and Quality Teams to determine your specifications for any project.

High Volume Screw Machine and Cold Header Finishing

Screw machine and cold heading operations run at a pace that leaves no room for slow finishing or unpredictable turnaround. The Lindgren Group’s Avtec Finishing Systems and Nico Products divisions support that level of production with facilities, staffing, and process control built for steady, high volume output. When machines run long shifts producing thousands of components, our finishing lines hold that same rhythm without adding pressure to your delivery dates.

Both facilities operate large finishing lines, rack and barrel plating systems, and automated equipment designed for continuous part flow. This includes barrel plating, mass finishing, and process equipment configured for the small format components produced by screw machine and cold heading shops every day. This approach aligns with the principles outlined in our high volume screw machine finishing insights, which focus on consistent capacity and reliable process control.

Quality Systems Built for Demanding Applications

Screw machine shops support customers across aerospace, defense, firearms, automotive, and industrial markets. These programs require a finishing partner with documented process control and the certifications your customers expect.

The Lindgren Group operates under ISO and Nadcap accreditation while maintaining Federal Firearms Licensing and aligning with ITAR, RoHS and Reach, NIST, and CMMC requirements. Each program moves through controlled bath chemistry, pre plate review, in process verification, and full lot traceability. This quality focus supports consistent finishes, reduces rework, and simplifies customer audits. It is one of the reasons work arrives from across the country.

Comprehensive Finishing Options for High Volume Work

 Production needs vary across industries. The Lindgren Group offers a broad selection of finishing capabilities that cover a large share of the chemical processes used by screw machine and cold heading operations. This range allows you to support multiple customers and specifications through a single finishing partner while keeping production schedules on track.

Capabilities include:

• Gold plating for electrical contacts and aerospace connector assemblies
• Electroless nickel for threaded parts, interior recesses, and complex geometries
• Passivation for stainless steel ammunition components and medical hardware
• Anodize and hard coat for aluminum components in demanding environments
• Zinc plating for fasteners and pins produced at scale
• Tin plating for electrical and solderable components
• Copper plating for conductive underlayers
• Mass finishing for consistent surface preparation before final coating

Additional context on finish selection appears throughout our coverage of screw machine finishing programs.

Expanded Automation for Steady, High Volume Output

Automation plays a significant role in keeping screw machine and cold heading production ahead of customer timelines. Avtec and Nico have invested heavily in automated lines for tin, copper, nickel, chrome, and barrel zinc plating, along with multiple upgrades in gold plating. These investments enhance consistency, increase capacity, and support rapid adjustments when order requirements change.

Two Sites, One Partner

Avtec and Nico function as coordinated finishing resources. When volume increases, production schedules tighten, or customer requirements shift, both facilities share the workload so your delivery dates remain intact. This structure provides screw machine and cold heading shops with the stability of a single partner backed by the capacity of two fully equipped plants.

Scaling With Your Operation

The Lindgren Group continues to expand capabilities, finishes, and automation to align with evolving customer demands. Screw machine and cold heading operations introducing new materials or finishing requirements can expect a partner ready to adapt and support new programs.

Ready to Move Your Production Forward

Provide your part print and finish requirements. The Lindgren Group will recommend the right finishing approach and deliver the capacity, consistency, and documentation that high volume screw machine and cold heading programs require.
