About Rotational Molding

Norwesco`s rotational molding of tanks began in 1980 with a single plant in St. Bonifacius, Minnesota. Now, that plant is the headquarters for thirteen additional manufacturing facilities across the U.S. and Canada. Norwesco is the world`s largest supplier of rotationally molded tanks and Plastics News has ranked us as one of the top ten rotational molders in North America!

Rotational molding is an efficient and effective process for molding hollow, complex and vertical shapes. The process uses heat to melt and fuse plastic resin in a closed mold, without utilizing pressure. All of our equipment has been customized to improve the speed and efficiency of the manufacturing process.
