Method for manufacturing plastic window

A method for manufacturing a plastic window, comprising:

• a mold preparation step for preparing a first mold having a first mold surface, a second mold having a second mold surface and being closed with the first mold to form a first cavity between the first mold surface and the second mold surface, and a third mold having a third mold surface and being closed with the first mold to form a second cavity having a product shape between the first mold surface and the third mold surface;
• a film preparation step for preparing a functional film having a transparent base of a sheet shape, a conductive portion formed on a back surface of the base, and a bus bar forming portion formed on the back surface of the base for forming a bus bar electrically connectable to the conductive portion, the functional film being thermally deformable;
• a placement step for placing the functional film on the first mold surface with the back surface of the base in contact with the first mold surface;
• a first injection step, wherein the first mold and the second mold are closed, wherein a first molten resin is injected into the first cavity to form a cover made of solidified opaque resin of the first molten resin, and wherein a first intermediate product provided with the cover on a peripheral edge portion of the functional film in an integral manner is made;
• a second injection step, wherein the first mold and the second mold are opened, wherein the first mold and the third mold are closed, wherein a second molten resin is injected into the second cavity to form a transparent body made of solidified transparent resin of the second molten resin and having a first surface and a second surface located on an opposite side from the first surface, and wherein a second intermediate product provided with the first intermediate product on a peripheral edge portion of the second surface in an integral manner is made;
• and
• a bus bar forming step for forming the bus bar on the bus bar forming portion to produce a product,
• wherein the first mold surface has a first forming portion forming the back surface of the cover and a second forming portion forming the second surface of the transparent body, and wherein in the placement step, the conductive portion is placed on the second forming portion and the bus bar forming portion is placed on the first forming portion.

A method for manufacturing a plastic window, comprising:

• a mold preparation step for preparing a first mold having a first mold surface, a second mold having a second mold surface and being closed with the first mold to form a first cavity of a plate shape between the first mold surface and the second mold surface, and a third mold having a third mold surface and being closed with the second mold to form a second cavity having a product shape between the second mold surface and the third mold surface;
• a preparation step for preparing a functional film having a transparent base of a sheet shape, a conductive portion formed on a back surface of the base, a bus bar formed on the same side as the conductive portion with respect to the base and electrically connectable to the conductive portion, and a colored portion formed on a front surface of the base or the back surface of the base in an overlapping manner with the bus bar and made of opaque color to prevent the bus bar from being exposed to the front surface of the base, the functional film being thermally deformable;
• a placement step for placing the functional film on the first mold surface with the back surface of the base in contact with the first mold surface;
• a first injection step, wherein the first mold and the second mold are closed, wherein a first molten resin is injected into the first cavity to form a transparent body made of solidified transparent resin of the first molten resin and having a first surface and a second surface located on an opposite side from the first surface, and wherein an intermediate product provided with the transparent body on the front surface of the base of the functional film in an integral manner is made;
• and
• a second injection step, wherein the first mold and the second mold are opened, wherein the second mold and the third mold are closed, wherein a second molten resin is injected into the second cavity to form a cover made of solidified opaque resin of the second molten resin with the conductive portion and the bus bar being exposed outside the cover, and wherein a product provided with the cover on a peripheral edge portion of the second surface in an integral manner is made.
