We have over 49 combined years of plastics manufacturing experience to produce plastic welding rod, 3d filaments, plastic pellets and other plastic goods for the industrial, small business and home based 3d printing industry.

All of our plastic welding rods are produced by the WeldiPlast team in the great State of Texas, USA.  So you need not worry if your next plastic welding job will look good due to poor quality plastic welding rods.
