Strategic Collaboration Between PPG, IPG Photonics and Whirlpool Corporation
PPG today announced a strategic collaboration with IPG Photonics, widely recognized as the global leader in fiber laser technology, and Whirlpool Corporation, one of the world’s most prominent home appliance manufacturers, to accelerate the broad-scale commercialization of laser curing systems for powder coatings. This collaboration represents a pivotal step forward in industrial finishing technology, uniting deep expertise in coatings science, laser engineering and high-volume appliance manufacturing. The primary focus of this joint effort is to identify and scale opportunities that significantly reduce curing costs, lower environmental impact and dramatically increase finishing line speed. By bringing together innovation-driven organizations across complementary industries, the initiative aims to transform how powder coatings are cured in mainstream manufacturing environments while delivering measurable operational and sustainability benefits.
Transforming Powder Coating Through Laser Curing Innovation
Traditional powder coating processes rely on thermal curing, where coated components are placed in large ovens and exposed to sustained high temperatures to trigger crosslinking, the essential chemical reaction that converts powder particles into a continuous, durable protective film. Laser curing, by contrast, uses precisely controlled infrared light energy to initiate this crosslinking reaction. Instead of heating entire ovens and surrounding air volumes, the laser directs energy specifically to the coated surface, enabling targeted, efficient curing. This approach is compatible with both conventional powder chemistries and formulations optimized specifically for laser curing applications. The result is a process that cures coatings in minutes, representing a fraction of the time required by traditional thermal methods and offering greater efficiency than standard infrared curing systems. By reducing the total heat required and shortening processing cycles, manufacturers can achieve meaningful energy savings, higher throughput and improved line productivity without sacrificing coating performance or durability.
Accelerating Commercial Adoption in High-Volume Manufacturing
The collaboration is not limited to laboratory validation or small-scale demonstrations. Instead, it is designed to accelerate commercial deployment in real-world, high-volume manufacturing settings. Whirlpool Corporation plays a critical role in this phase, providing practical manufacturing environments and diverse appliance components to test powder formulations cured with IPG’s advanced PhotoniCURE laser system. Through structured pilot trials, the partners are evaluating how various powder chemistries perform across different substrates, shapes and production conditions. These trials assess not only curing performance and coating durability but also cycle time improvements, energy consumption metrics and overall operational efficiency. By rigorously testing the system in appliance manufacturing contexts, the collaboration aims to build a robust value proposition that can be replicated across other industrial sectors seeking more sustainable and cost-effective finishing technologies.
Installation of Advanced Pilot and Research Systems
To support commercialization efforts, PPG has installed a state-of-the-art pilot finishing line featuring IPG’s PhotoniCURE laser curing system at its powder manufacturing and technical facility in Strongsville, Ohio. This advanced line allows engineers and customers to simulate production-scale operations while evaluating coating performance and process optimization strategies. In addition, a laboratory-scale laser curing system has been deployed at the PPG Coatings Innovation Center near Pittsburgh. This facility enables research feasibility studies, formulation development and detailed analysis of curing dynamics under controlled experimental conditions. Together, these installations create an integrated development ecosystem where coatings scientists, laser engineers and manufacturing specialists can collaborate to refine both materials and processes. The pilot infrastructure also provides a demonstration platform for customers interested in exploring laser curing solutions for their own production environments, further accelerating adoption across the industry.

Senior leaders from each organization have emphasized the significance of the collaboration as a transformative milestone for the coatings and manufacturing industries. At PPG, executives describe the initiative as positioning the company at the forefront of powder finishing innovation, reinforcing its commitment to delivering value beyond the physical coating itself. By integrating advanced curing technologies with high-performance powder formulations, PPG demonstrates its “outside-the-can” capabilities, offering customers comprehensive solutions that enhance productivity and sustainability. Whirlpool’s leadership highlights the energy-intensive nature of industrial finishing processes and underscores the importance of participating in the development of laser-curing capabilities to reduce environmental impact and operational costs. IPG Photonics views powder coating as a natural extension of its laser technology expertise, anticipating growing demand for PhotoniCURE systems as sustainable manufacturing trends intensify worldwide. Collectively, these perspectives illustrate a shared belief that laser curing represents a substantial advancement in finishing technology with long-term strategic implications.
Energy Efficiency and Environmental Impact Reduction
Industrial finishing processes are among the most energy-intensive operations in manufacturing facilities, often requiring large convection ovens operating at high temperatures for extended durations. By replacing or supplementing these thermal systems with targeted laser curing, manufacturers can dramatically reduce overall energy consumption. Lower heat requirements translate directly into reduced greenhouse gas emissions, particularly in facilities powered by fossil fuel-based energy sources. Faster curing cycles also minimize idle time and improve equipment utilization rates, enabling more parts to be processed in less time. Beyond energy efficiency, laser curing can reduce waste associated with overbaking, rework and temperature variability. These sustainability advantages align with broader global initiatives aimed at decarbonizing manufacturing and improving resource efficiency. For companies like Whirlpool, which maintain ambitious environmental goals across global operations, integrating laser curing technology could become a key lever in achieving measurable reductions in environmental footprint while maintaining product quality and performance standards.
Expanding Laser Solutions into Mainstream Manufacturing
For IPG Photonics, the collaboration marks a strategic expansion of laser technology into new industrial domains. While lasers are already widely used in cutting, welding and marking applications, their role in curing powder coatings introduces a novel application with significant market potential. As the global leader in fiber laser systems, IPG brings deep expertise in laser source design, beam delivery systems and industrial integration. The PhotoniCURE system leverages these strengths to deliver controlled infrared energy optimized for powder coating crosslinking. As joint trials with PPG and Whirlpool demonstrate scalability and economic viability, IPG anticipates broader demand from manufacturers seeking sustainable finishing alternatives. The convergence of energy efficiency mandates, rising utility costs and environmental regulations creates favorable conditions for adoption. By validating performance in volume production, the partners aim to demonstrate that laser curing is not merely an experimental technology but a practical, commercially viable solution for mainstream manufacturing operations.
