Abstract
According to the present invention, a manifold mounting arrangement is provided wherein a leg manifold is securely mounted midway along its length rather than at its sprue bushing and whereby thermally induced length changes are accommodated outwardly from its centre. Additionally, a first end of the leg manifold is clampingly secured between a sprue housing and a manifold insulator to avoid movement of the first end toward the sprue upon a sprue break portion of the injection moulding cycle.
