Rotational Molding
Rotational molding is a manufacturing process used to produce hollow plastic parts by heating and rotating a mold containing plastic resin powder. The process involves placing powdered plastic into a mold, which is then heated while rotating biaxially to distribute the material evenly along the mold walls, followed by cooling to solidify the part. It is particularly suited for creating large, seamless, and complex hollow objects with uniform wall thickness.
Developers in manufacturing, industrial design, or materials engineering should learn rotational molding when designing durable, one-piece plastic products like tanks, containers, toys, or automotive components, as it offers cost-effectiveness for low to medium production volumes and minimal waste. It is ideal for applications requiring high impact resistance, chemical stability, and intricate shapes that are difficult to achieve with other molding methods, such as blow molding or injection molding.
