At the International Manufacturing Technology Show (IMTS), industry professionals gather with a shared goal: advancing their businesses. Regardless of your role within the manufacturing process chain, it’s impotant to prioritize the finishing of your parts from the outset. Whether you manage finishing in-house or rely on outsourcing, early consideration of the final finish will help ensure quality.

The traditional approach of merely machining parts and sending them to a metal plater is outdated and should be left in the past. To achieve the highest quality, it’s essential to collaborate closely with every partner in your process chain, including surface finishing experts.

What are the current trends in surface finishing? Industry professionals are focusing on several key areas that shouldn’t come as a surprise.

1. AI, machine learning and IoT solutions

Much like other areas of manufacturing, finishers and coaters are seeking ways to streamline their processes. Today, finishers are increasingly exploring robotics, artificial intelligence (AI) and machine learning to tackle challenges such as workforce shortages, quality control and repeatability.

Historically, finishing operations have been slower to adopt IoT and automation solutions due to the high mix of parts typically processed by job shops, but various factors — including workforce trends and demands for environmentally responsible and sustainable processes — are accelerating the need to find new efficiencies.

Discover how one company is using AI to make finishing processes for a high mix of parts of varying geometries as easy as the push of a button.

2. 3D Printing

Additive manufacturing is growing exponentially. As this technology continues to move from the realm of R&D and short run production to full scale production, an increasing number of fabricators are looking to various finishing methodologies to not only protect parts or provide aesthetics but in some cases to increase functionality.

Check out a story about how one company is using electroplating to enhance the physical properties of additively manufactured parts.

3. Electroless Nickel Plating and EVs

The advent of electric vehicles (EVs) seems to have finally arrived. With a growing number of automotive OEMs investing in new capabilities to grow their EV and hybrid offerings, finishes will be needed for a range of parts from electrical motor components to batteries.

One example is electroless nickel (EN) plating. EN has been used in the automotive industry for decades. Applications include piston heads, carburetors and fuel injection components, slip yokes and transmission components. Today, EVs present exciting new opportunities for additional growth of EN in the automotive market with the finish being used for several critical components used in electric vehicles.

4. Environmental Considerations

Contrary to some perceptions, environmental concerns are a priority in the finishing industry. As one of the most heavily regulated sectors in manufacturing, compliance is essential for the industry’s sustainability. For years, metal finishers have been engaged in negotiations with environmental groups to address issues related to air quality and wastewater treatment. The industry has been proactive in seeking alternatives to potentially harmful hexavalent chromium finishing technologies, exploring safer options like trivalent chromium-based processes. The evolving regulatory landscape will continue to influence the available finishing technologies and their application methods.

This Products Finishing Ask the Expert column, discusses the environmental considerations driving some of these regulations:

In terms of coatings, powder coating has always been a low volatile organic compound (VOC) approach to coating parts, and powder overspray is a reclaimable material. Despite its already environmentally-friendly nature, new ways of making powder coating even more sustainable are being explored.

Check out this story about two companies that have found novel approaches to reclaiming powder.

5. Plating on Plastics

Plating on plastics (POP) isn’t new. Electroplating on plastic typically involves the process of depositing a thin layer of metal onto a plastic substrate using an electrochemical process after first preparing the plastic for the metal to adhere. Advances in plating on plastics, as well as the introduction of new materials aimed at producing lightweight parts are creating opportunities beyond traditional POP applications, which are often decorative in nature. Today, POP is being explored for use in diverse industries, including aerospace, automotive and electronics. The ability to electroplate on high-performance resins, lightweight composites and additively manufactured parts opens new avenues for innovation, making plating on plastic an option for enhancing functionality of parts in addition to providing esthetics.
