Abstract

1446969 Encapsulation moulding ARO PLASTICS DEVELOPMENT Ltd 9 April 1975 [29 April 1974] 18769/74 Heading B5A A product comprising a metal reinforcement encapsulated in a polymer (e.g. a pallet) is formed by moulding the polymer around a reinforcement which contains at least one telescopic member, the telescopic member being capable of reducing in length under the stress set up in the product by shrinkage of the polymer during setting after moulding. In the embodiment shown in Fig. 2, the telescopic action is provided by allowing steel reinforcement elements 3 to slide inside a close-fitting steel sleeve 4.
