Plastic Rotational Mould & molding
Plastic Rotational molding is a known rotation used in the manufacture of various sizes and shapes of the hollow seamless product processing methods. Traditionally, it is mainly used in thermoplastic materials, in recent years, can be cross-linked polyethylene rotational molding thermosetting materials are also developing rapidly. As the rotational molding does not require a higher injection pressure, high shear rate or the precise compound meter. Therefore, the mold and machine are relatively low poly, but also a longer service life. The main advantages are: the machine's performance / price higher; complex parts after the molding does not require assembly; a variety of products and a variety of colors can also forming; lower the cost of mold; easy to change colors and materials; scrap loss less.
