Are you looking for a plastic tank manufacturer? Gregstrom Corporation is a rotational molder in Woburn, Massachusetts (USA) that makes liquid storage tanks, water tanks, wastewater tanks and many other types of plastic products. As a manufacturing process, rotational molding creates strong hollow shapes with features like multiple walls and molded-in hardware. Along with low tooling costs and quick tooling modifications, rotomolding lets a plastic tank manufacturer provide design flexibility.

Liquid Storage Tanks

Liquid storage tanks can range in size from tens to thousands of gallons. They are used to store chemicals, fluids, beverages, and many other types of fluids. These plastic tanks are also used in the bulk handling of soaps, detergents, oils and fuels. Rotomolding materials for liquid storage tanks include linear low-density polyethylene (LLDPE), a durable plastic that can withstand a wide range of temperatures and won’t react with detergents, acids or bases. Cross-linked polypropylene and polyethylene are used in fuel tanks.

Water Tanks

Rotomolded tanks for potable water are manufactured using plastic resins that meet requirements from the U.S. Food and Drug Administration (FDA). Plastic water tanks are also available that meet standards from the National Sanitary Foundation (NSF) or the U.S. Department of Agriculture (USDA). Unlike metal tanks, plastic tanks don’t have seams, joints, or welds that can rust. Rotomolding materials for water tanks  include LLDPE and high-density polyethylene (HDPE).

Wastewater Tanks

Wastewater tanks that are rotomolded weigh less than metal tanks and can feature rugged, corrosion-free designs. With recreational vehicles (RVs) and boats, black water tanks are used to hold wastewater until it can be disposed of properly. Gray water tanks are used to hold wastewater from sinks, showers or washing machines. The chemical composition of the wastewater that a rotomolded tank must hold helps to determine which type of rotomolding material to use.
