Rotational molding is a versatile plastic manufacturing process that allows for the manufacturing of a wide variety of products, including plastic tanks, toys, containers, and medical device components. It is a process that involves heating a plastic resin in a mold while simultaneously rotating the mold in two perpendicular axes. This causes the molten resin to evenly distribute and adhere to the walls of the mold, resulting in a seamless, hollow product.

When Was Rotational Molding Developed?
Rotational molding was first developed in the 1940s and was initially used to create hollow, seamless toys such as basketballs and dolls. The process gained popularity in the 1950s as a cost-effective method for producing large, lightweight items such as water storage tanks and fuel tanks.
What Are the Main Differences Between Rotational Molding and Other Plastics Molding Techniques?
One of the main differences between rotational molding and other plastics molding techniques, such as blow molding and injection molding, is that it doesn’t require a high-pressure molding process. Instead, the plastic resin is melted in a low-pressure oven and then slowly rotated in the mold. This allows for greater design flexibility and the creation of more complex shapes.
Another key advantage of rotational molding is that it doesn’t require the use of expensive molds. This means that prototypes and small production runs can be produced at a lower cost than with other molding techniques.
