Plastic Rotational Molding of a Water tank

At Lerner Molded Plastics 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.
