Do you believe new industrial manufacturing technologies will eventually lower prices for your home appliances?
IPG Photonics is collaborating with PPG and Whirlpool to test laser curing technology as a more efficient alternative to traditional oven-based methods for appliance coatings. This innovation could potentially reduce production time for powder coating lines to just 15 minutes.
Why it matters
By replacing large, energy-intensive ovens, this technology could improve the efficiency of appliance manufacturing. This shift aims to optimize the coating process by focusing energy directly on the substrate interface.
The new laser curing process targets a 15-minute production cycle for appliance powder coatings. This represents a potential shift away from standard oven-based drying methods used throughout the industry.
The players
IPG Photonics
A developer of fiber lasers that serves industrial and manufacturing markets.
PPG
A major supplier of paints, coatings, and specialty materials used in household appliances.
Whirlpool
A global manufacturer of home appliances including washers, dryers, and refrigerators.
The details
Laser curing works by directing energy specifically into the interface between the coating and the substrate rather than heating an entire oven. Developing powder coatings optimized for laser absorption is key to making this process efficient and viable for large-scale appliance manufacturing.
Timeline
The evaluation was featured at the 2026 Coatings Trends & Technologies Summit.
The Home Front
This development represents a shift in appliance manufacturing, moving away from energy-heavy oven systems toward more precise laser-based curing. Such innovations could change the cost and efficiency profile of the appliances installed in homes.
While you do not need to take immediate action, consider the energy efficiency of your appliances as manufacturers adopt new production technologies. Staying informed about industry changes can help when you are eventually shopping for new, more efficient kitchen and laundry machines.
The takeaway
Manufacturers are exploring laser technology to streamline the curing process for appliance finishes. Keep an eye on energy efficiency labels when upgrading your home gear, as these production changes may eventually influence how household machines are built and powered.
