Abstract

Device for centrifugal casting of liquid binder resins into a series of moulds pref. preloaded with suitably shaped glass fibre reinforcement. The moulds (9) are supplied with resin (5) from a reservoir (6) whose height is adjustable to ensure that the liquid level in the reservoir is at least as high as the high points of the moulds. The moulds are rotated (1, 2, 3) through an annular chamber (13) incorporating heaters (12). A vent pipe (10) branches off the resin supply pipe (7) and returns to the reservoir at a level high enough and with sufficient projection (11) to vent the mould and return excess resin when the mould is full to a point visibly clear of the concave liquid resin surface in the rotating reservoirs. Pref. the vent/resin return line has a capacity at least as great as the fill time. Pref. the vent line indicates in some way when the mould is full, and thus automatically activates a cycle time control.
