The simplicity of the process allows for a mold which is fairly simple itself, meaning a rotational molding mold is less expensive than other forms of plastic manufacturing. It also means that very large molds can be made, which in turn will produce larger parts than most other processes. Although roto-molding lends itself to less expensive tooling, the parts themselves can run more expensive as the process takes much longer to create a single part than, say, blow molding or injection molding. This means that roto-molding is a great choice when lower quantities of around 500 or less annually are needed.
