Abstract
A front loading spin caster for spin casting a mold includes a vertically stationary top plate, a vertical movable bottom plate, a housing in which the top and bottom plates are disposed, a loading door disposed on one of the sides of the housing and adapted to allow the mold to be moved therethrough in a generally horizontal direction and placed on the bottom plate. The bottom plate can then be moved vertically upward to cause the mold to contact the top plate and a rotational force applied to the top plate propagates from the top plate through the mold to the bottom plate, the top plate, bottom plate and mold thus rotating together.
Claims3
A method of spin casting a mold in a spin caster, comprising:
- loading a mold through a side of the spin caster housing onto a vertically movable bottom plate adapted to rotate about a substantially vertical axis, and underneath a vertically stationary top plate adapted to rotate about said substantially vertical axis;
- moving the bottom plate vertically upward to cause the mold to contact the top plate;
- applying a rotational force to the top plate which propagates through the mold to the bottom plate to thus cause the top plate, the bottom plate and the mold to rotate together;
- introducing a liquid material into the mold through an aperture in the top of the top plate;
- terminating the rotational force;
- moving the bottom plate vertically downward;
- and
- removing the mold through the side of the housing.
