Roto Molding for Marine Water Tanks

rotomolding process graphicMarine water tank manufacturing begins with the meticulous process of roto molding. High-quality virgin polyethylene resin is carefully heated and melted inside a sealed mold. This mold is then placed in a casting and heated to temperatures ranging from 260°C to 370°C. As the mold rotates, the molten resin uniformly coats its interior, ensuring the creation of smooth, strong walls with consistent thickness throughout. The result is a remarkably durable marine water tank that boasts exceptional strength and a seamless construction. Seamless is important in the tank world, as by having no seams, it eliminates weak points that are prone to cracking and leaking. With its robust design, these water tank offers longevity, providing you with a reliable and long-lasting solution for your marine water storage needs.
