Unlike other polyethylene moulding processes, rotational moulding does not involve pressure loading. Consequently the mould tools can use more cost-effective materials such as sheet steel and aluminium. Furthermore, rotational moulding tools are simpler to construct as they require only a female element and this can significantly reduce project lead times.
Few processes use materials as costeffectively or with as little environmental impact as rotational moulding. The vast majority of rotationally moulded products use thermoplastics such as polyethylene or polypropylene which can be recycled and re-used as well as enhancing your environmental policy.
