Abstract: A new process and technical arrangement has been established for the production of grain free metal products, which can be extruded directly from the melt, by inserting a seed crystal from a seeding chamber into the opening of the extrusion jet of the melting vessel. The seed crystal will break by contact the surface tension of the liquid metal in the extrusion jet channel, which is slightly undercooled. Upon establishing contact, the temperature at the meeting point of the seed crystal and the liquid metal will be raised by RF-heating to permit the extrusion of the seed crystal backwards, ensuring that metal and seed crystal maintain contact and crystal growth will continue. It has been discovered, that single crystals with the orientation of the seed crystal will continue to grow and to establish high hardness. Speed of extrusion is exceeded to reach only grain free structure in the grown metal.

Abstract: Disclosed is a method of molding a resin coated bearing. When a molten resin is injected toward a substantially central portion of a disk space of forming dies from a sprue formed on an upper die, the molten resin is filled into a cavity through a film gate after the molten resin is led to the disk space from a pin gate, so that any weld is absent on a resin member, which covers an outer race, thus enabling uniformizing a coating member in resin strength and suppressing generation of crack on the coating member even at the time of high loading. Also, since the film gate formed on a whole peripheral edge of the disk space is formed from a lower die and an upper die, there is an advantage that after working suffices to take out a resin coated bearing from the both dies and to cut a runner in the disk space.

Simultaneously, the vibration table is designed such that force and stress flow in the vibration table is optimized.
