Why Rotational Molding
Rotomoulding, or rotational molding is the process of forming a hollow object using a closed split mold. Plastic pellets are placed into the molding chamber, then heated and mounted on a rotational station. The rotational molding machine spins around, first slowly than faster as the pellets inside the mold melt. This causes the melted plastic to coat the entirety of the mold evenly. The heat is then turned off, and the machine continues to rotate until the plastic hardens. The product can then be removed from the mold.
