What is Rotomolding?

Rotomolding, also known as rotational molding, is a versatile plastic molding process used to create hollow objects. This method involves heating plastic powder in a mold as it rotates around two perpendicular axes. The result is a uniform, seamless, and durable product.As technology advances, the future of rotomolding looks promising. With ongoing research into new materials and processes, rotomolding is set to become even more efficient and versatile, opening up new possibilities in manufacturing.

History of Rotomolding

Understanding the history of rotomolding is essential for gaining comprehensive rotomolding knowledge. The process dates back to the early 20th century, initially used for making hollow chocolate eggs and other small items. It wasn't until the 1940s that rotomolding began to be applied to plastics, leading to significant advancements in manufacturing technology.

Advantages of Rotomolding

  • Cost-effective: The molds used in rotomolding are less expensive than those used in other molding processes.
  • Design Flexibility: Rotomolding allows for the production of complex shapes and sizes without the need for seams or joints.
  • Durability: Products created through rotomolding are known for their strength and longevity.
