Method for manufacturing member, apparatus for manufacturing member, and die

An apparatus for manufacturing a member, the apparatus comprising:

• a die having a first die member with a first molding surface and a second die member with a second molding surface;
• a drive system that causes the first molding surface and the second molding surface to approach each other or to separate from each other;
• and
• a temperature control unit that controls a temperature of the die,
• wherein at least one die member of the first die member and the second die member has a material part or a space part that changes a curvature of the first molding surface or the second molding surface, which is a molding surface, due to a change in heat or load.

A die comprising:

• a first die member having a first molding surface;
• and
• a second die member having a second molding surface,
• wherein at least one die member of the first die member and the second die member has a material part or a space part that changes a curvature of the first molding surface or the second molding surface, which is a molding surface, due to a change in heat or load.
