What is Rotational Molding

Rotational molding is a unique type of tank fabrication that starts with heating plastic resin inside a hollow, closed mold. The resin melts inside the mold after it is placed inside a cast. Temperatures range from 260°C to 370°C. Continually rotated, the mold is evenly coated with the polyethylene resin. Centrifugal force created during rotation produces a smooth, watertight product with even, consistent walls. Once the plastic cools and hardens, it is immediately removed from the mold, making it faster and more cost effective than other forms of molding. Roto mold tanks have a longer life expectancy than tanks made with the injection method, and they are strong enough to withstand impact and vibration created during transportation.
