Abstract:
1. A manufacturing method for producing a bound body composed at least partially of particulate material, the method including the steps of: providing a feed material which includes a substantial proportion of particulate material, introducing to the feed material a binder which includes a heat curable or activated adhesive substance so that the binder contacts significant proportions of the surfaces of the particulate material, feeding a mixture of feed material having the binder therein into a die so that it adopts substantially a shape of a bound body to be produced, and heating the mixture in the die until the binder has cured sufficiently to enable further handling as an integral bound body comprising bound particulate materials, wherein the method includes the further step of feeding the mixture through an intake zone defined by intake guides composed of insulating material prior to entering the die which forms a continuous extension of the intake zone so that the mixture passes from the intake zone into the die without any intervening transition zone, the mixture being fed through the intake zone being shaped therein into substantially the same shape it adopts when subsequently fed into the die so that the mixture in the intake zone is a continuous extension of the mixture in the die and so that any progress of curing of the binder due to heating the mixture resident in the intake zone is effective in curing the binder while the mixture in the intake zone is in a desired final shape.
