How does rotational molding work?
Simply stated rotational molding is a process by which plastic products are manufactured for a variety of applications. The process itself is a molding cycle that goes through 4 different phases. The first phase is referred to as the charging phase, during this phase a material or resin is charged into the mold and the mold is sealed for phase two. During the second phase the mold is heated to a desired temperature while rotating on two specific axes. Phase 3 consists of a cooling stage where the mold begins to cool and the plastic begins to solidify and maintain the shape of the mold. Once the plastic resin has cooled long enough to hold its own shape we enter into phase 4. During this final phase the mold will be reopened and the part will be de-molded producing a solid plastic product.
