Windshield Wiper Blade manufacturing is one of the industries that has been lost to China a long time ago. Rubber manufacturing and many small parts coming together at assembly time makes manufacturing complicated. There are many American and European companies, but most offshore manufacturing. Here is a list of the ones we could find that are not made in China.
Trico is an old American company who has been pioneering wiper technology for over 100 years. All the components for the wiper blades and assemblies are made in the USA. The Titan, Maxx and Ultra models are assembled in the USA as well. The rest of their blades are assembled in Mexico.
