IPG Photonics is collaborating with PPG and Whirlpool to evaluate a new industrial laser curing process. By replacing conventional ovens, this method could significantly accelerate manufacturing timelines for appliances.
Why it matters
Developing specialized powder coatings for laser absorption offers a more energy-efficient way to cure finishes. This innovation targets the efficiency of the coating and substrate interface, potentially shortening production cycles.
The proposed laser curing technology could enable a 15-minute powder coating line. This process works by directing energy directly into the coating and substrate interface.
The players
IPG Photonics
An American manufacturer of fiber lasers and amplifiers used in a wide range of industrial applications.
PPG
A global supplier of paints, coatings, and specialty materials for industrial and consumer use.
Whirlpool
A major multinational manufacturer and marketer of home appliances including refrigerators and washers.
The details
Laser curing technology focuses energy directly where needed rather than heating an entire oven to cure coatings. IPG Photonics, PPG, and Whirlpool are working together to test if these systems can effectively handle the requirements of appliance manufacturing.
Timeline
The evaluation of the laser curing technology was discussed during the 2026 Coatings Trends & Technologies Summit.
Culture Shift
The report presented at the 2026 Coatings Trends & Technologies Summit marks a technical shift in how appliance manufacturers view thermal processing. This move toward localized energy application represents a broader industrial trend of replacing energy-intensive legacy infrastructure.
While this technology is currently in the testing phase, successful adoption could lead to faster manufacturing times for the household appliances you purchase. Shorter production cycles may eventually influence how quickly new models are brought to market.
The takeaway
Laser curing represents a move toward more precise energy use in manufacturing. Homeowners should look for future appliance finishes that may become more durable or efficient as a result of these new curing processes.
