Plastic Rotational Molding of a Water tank

At Lerner and Associates, LLC we specialize in plastic rotational molded products, in a wide range of sizes; this service is exemplified by this water purification tank. The tank was fabricated on our Large Hercules multiple spider rotational molding machine. The linear low-density polyethylene (LLDPE) used to fabricate the tank featured a minimum thickness of .125". Tank halves measured 7' 10.5" in length, 4' 9.5" in width, and 1' 7.75" in height, and were fabricated with a textured finish.

Per our PPAP process first article samples were provided to the customer for approval. We currently roto mold 1,000 of these tanks per year with lead times of 8 weeks. For more information on this project or all of our precision rotational molding services, see the table below or contact us directly.
