rotational injection molding
Rotational injection molding, also known as rotomolding, is a versatile manufacturing process used to create hollow, seamless parts. The main functions of this technology include producing complex shapes, large parts, and uniform wall thickness. Technological features of rotational injection molding involve the use of a hollow mold that is filled with polymer powder, rotated on two axes, and heated to melt the powder against the mold's inner surface. Once cooled, the part is ejected for finishing. This process is ideal for a wide range of applications such as automotive parts, marine products, and large storage containers, offering design flexibility and cost efficiency.
