    Why surface finishing is a key enabler for Industry 4.0

    As we kick off 2026 as Kensington360, we’re going deeper into advanced materials and the technologies that underpin modern manufacturing.

     

    Our materials specialist Luke Harrison shares why surface finishing is a key enabler of Industry 4.0 from performance and repeatability to qualification and scalability.

     

    Introduction: Discovering an Industry Hiding in Plain Sight

     

    Coming from a recruitment background rooted in advanced manufacturing, I’ll be honest. Surface finishing was not an industry I initially understood in depth. Like many people outside of it, I thought of it as a final step. Something important, but largely transactional. Over the last year, speaking with hiring managers, plant leaders, process engineers, and operations teams across North America, that perception has completely changed.

    What I have learned is that surface finishing is not just supporting Industry 4.0. It is one of the quiet enablers of its growth.

    Every conversation eventually lands on the same reality. You can design the most advanced component in the world, but if the surface fails, the part fails. Whether that part sits in an aircraft engine, an EV battery pack, a medical implant, or a defense system, the finish is what determines durability, safety, and performance.

    From a recruitment perspective, surface finishing sits at the intersection of materials science, manufacturing execution, quality systems, and increasingly, digital technology. As Industry 4.0 accelerates, this sector is becoming more strategic, more data driven, and more talent constrained than many people realize.

     

    Market Growth Is Pulling Surface Finishing Forward

     

    One of the most consistent themes I hear from leadership teams is workload growth. Not just more work, but more complex work. The growth of advanced manufacturing sectors is directly increasing demand for high performance surface finishing.

    Aerospace and defense continue to push materials to their limits. Lightweight alloys, thermal barriers, corrosion resistance, and life extension coatings are no longer optional. Finishing processes are critical to meeting flight safety standards and defense durability requirements. Many of the hiring managers I speak with are scaling capacity specifically because aerospace programs are expanding or re-shoring.

    Automotive and EV manufacturing is another major driver. The transition to electric vehicles has introduced new materials, new thermal challenges, and new electrical conductivity requirements. Battery housings, connectors, power electronics, and lightweight structural components all require precise surface treatments. Finishing teams are no longer just protecting parts. They are enabling energy efficiency and reliability.

    Medical manufacturing brings a different type of pressure. Growth here is driven by aging populations, personalised devices, and higher regulatory expectations. Surface finishing plays a defining role in biocompatibility, sterilisation, and implant longevity. From a hiring perspective, medical focused finishing operations demand extreme process discipline, documentation, and repeatability.

    What ties all of this together is that growth in these sectors does not reduce complexity. It increases it. Surface finishing companies are expected to scale while also tightening tolerances, improving traceability, and meeting sustainability targets.

    That is where Industry 4.0 enters the conversation.

     

    Industry 4.0 Is Changing How Finishing Plants Operate

     

    When people talk about Industry 4.0, they often picture robots, CNC machines, or additive manufacturing. Through recruitment discussions, I have seen how deeply those same principles are now embedded in finishing operations.

    Many finishing plants are implementing real time monitoring across chemical baths, coating lines, and paint systems. Sensors track temperature, concentration, thickness, and environmental conditions continuously. What used to rely on periodic checks is now managed as a live system.

    Manufacturing execution systems are becoming central. Finishing is no longer an isolated department. It is digitally connected to upstream machining, additive processes, heat treatment, and inspection. This creates a single digital thread where every surface treatment step is logged, auditable, and repeatable.

    Automation is also more common than I expected. Robotic handling, automated spraying, and controlled immersion systems are improving consistency while reducing operator exposure to hazardous environments. From a talent perspective, this changes the skill mix required on the shop floor.

    Artificial intelligence and data analytics are starting to influence quality and maintenance decisions. I have spoken with leaders using historical process data to predict bath degradation, filter changes, or defect risk. Instead of reacting to failures, they are preventing them.

    Digital twins are also creeping in. Virtual simulations of coating processes allow teams to optimise parameters before production begins. This is particularly valuable when dealing with complex geometries or new materials.

    What stands out is that Industry 4.0 in surface finishing is not about hype. It is about control, repeatability, compliance, and scale. All things that directly impact customer trust.

     

    What This Means for Talent and Hiring

     

    From a recruitment standpoint, this convergence is creating a very real talent challenge.

    The industry still relies heavily on deep process expertise. People who understand chemistry, metallurgy, coatings, and finishing workflows through years of experience. That knowledge remains irreplaceable.

    At the same time, finishing operations increasingly need people who are comfortable with data, automation, software, and systems thinking. The strongest teams I see are not siloed. They blend traditional finishing expertise with digital literacy.

    Hiring managers are asking for engineers who can bridge finishing and manufacturing systems. Quality leaders who understand both compliance and digital traceability. Maintenance and automation specialists who can support chemically intensive environments. Operations leaders who can manage growth without losing control of process stability.

    This is not an easy combination to find. Many companies are choosing to upskill internally, investing in training and career development. Others are hiring from adjacent industries and teaching finishing fundamentals. Both approaches work, but both require intent.

    What is clear is that Industry 4.0 is raising the bar. Finishing is no longer a back end function. It is a strategic capability that demands strong leadership and the right people.

     

    A Recruiter’s Takeaway

     

    Coming into this industry from the outside has been eye opening. Surface finishing does not always get the attention it deserves, but it sits at the heart of modern manufacturing growth.

    Industry 4.0 is accelerating expectations around quality, data, sustainability, and speed. Market growth in aerospace, EV, medical, and defense is amplifying those pressures. Surface finishing is where those forces converge.

    For hiring managers, the opportunity is significant. Companies that invest in technology, process integration, and people are positioning themselves as indispensable partners to advanced manufacturers. Those that do not will struggle to keep pace.

    From a recruitment perspective, I now see surface finishing as one of the most important talent battlegrounds in advanced manufacturing. Quietly complex. Technically demanding. And absolutely integral to the future of Industry 4.0.
