Abstract
A method for manufacturing a glass plate equipped with a vehicle window-type resin frame includes performing injection molding of the resin frame by using two shaping molds having a cavity configured for the resin frame, disposing the glass plate inside the shaping molds such that the glass plate is retained by a retaining part that is adjacent to the cavity of the shaping molds, and injecting a resin into the cavity, wherein there is at least a partial gap between the glass plate and the retaining part, in a state in which the shaping molds are clamped together.
Claims12
A method for manufacturing a glass plate equipped with a vehicle window-type resin frame, the manufacturing method comprising:
- performing injection molding of the resin frame by:
- using two shaping molds having a cavity configured for the resin frame;
- disposing the glass plate inside the shaping molds such that the glass plate is retained by a retaining part that is adjacent to the cavity of the shaping molds;
- and
- injecting a resin into the cavity, wherein
- there is at least a partial gap between the glass plate and the retaining part, in a state in which the shaping molds are clamped together,
- the gap has a gap distance of 0.5 mm or less,
- in the injection molding, information regarding at least the gap between the glass plate and the retaining part is acquired and the injection molding is controlled by utilizing the information regarding the gap, and
- the information regarding the gap is estimated from either or both of pressure and displacement of the glass plate.
