Abstract
A molding apparatus for patterning a workpiece includes a first support member for supporting the mold, a second support member arranged opposite to the first support member, and a pressing mechanism for pressing the mold and the work together using the support members to pattern the workpiece. In this structure, either the surface of the first support member for supporting the mold or the surface of the second support member for supporting the workpiece is smaller in area than both surfaces of the mold and the workpiece.
Claims11
A molding apparatus for patterning a workpiece using a mold, comprising:
- a first support member for supporting the mold;
- a second support member, arranged opposite to said first support member, for supporting the workpiece;
- and
- a pressing mechanism applying pressure by bringing said first and second support members toward each other and pressing the mold and workpiece together so as to pattern the workpiece,
- wherein said first support member has a first press surface with outer edges and said second support member has a second press surface with outer edges, and the outer edges of at least one of the first press surface or the second press surface are smaller in outer dimension than the mold and the workpiece,
- wherein the first press surface contacts a surface of the mold, and the second press surface contacts a surface of the workpiece, and the pressure applied by the pressing mechanism is transmitted only through the contact surfaces, and
- wherein both the press surface of said first support member and the press surface of said second support member are smaller in area than the mold and the workpiece.
A molding apparatus for transferring recessed and raised features of a mold to a workpiece, comprising:
- a first support member for supporting the mold;
- a second support member, arranged opposite to said first support member, for supporting the workpiece;
- and
- a pressing mechanism applying a pressure by pressing said first and second support members together to transfer a pattern of the mold to the workpiece;
- wherein a press surface of said first support member has a first press surface with outer edges,
- a press surface of said second support member has a second press surface with outer edges, and the outer edges of the first press surface and the second press surface are smaller in outer dimension than the mold and the workpiece, and
- wherein the first press surface contacts a surface of the mold, and the second press surface contacts a surface of the workpiece, and the pressure applied by the pressing mechanism is transmitted only through the contact surfaces.
A molding apparatus for patterning a workpiece using a mold, comprising:
- a first support member for supporting the mold;
- a second support member, arranged opposite to said first support member, for supporting the workpiece;
- and
- a pressing mechanism applying pressure to said first and second support members together to transfer a pattern of the mold to the workpiece;
- wherein a press surface of said first support member on a mold side has a first press surface with outer edges smaller in area than the surfaces of the mold and the workpiece,
- the first press surface of said first support member and a second press surface of said second support member are substantially plane symmetrical to each other with respect to a contact surface of the mold and the workpiece, and
- wherein the first press surface contacts a surface of the mold, and the second press surface contacts a surface of the workpiece, and the pressure applied by the pressing mechanism is transmitted only through the contact surfaces.
