| 摘要 |
A method for rotational moulding of articles, including the step of rotationally moulding a mixture of particulate plastics material comprising at least one thermoplastics material having a first particle size and a second thermoplastics material having a larger particle size wherein, in use, said first thermoplastic material fuses to form an outer skin (5) and subsequently said second thermoplastics material fuses to form an inner skin (6) bonded to the outer skin of a resultant moulded article. The method may also include the step of incorporating a quantity of rollable moulded reinforcing elements (7) in the mould with said first and second thermoplastics materials, wherein the reinforcing elements are located in a spaced array thereby forming bridges between opposed inner skin surfaces as they expand. Articles, such as a shipping pallet, rotationally moulded using the method are also disclosed.
