Problems solved by technology

In addition, when no dents are found and the foil dust P is not wiped off, there is a danger of continuous manufacturing of defective items.
[0012] Particularly, in a sub-liquid crystal panel of a cellular phone or the like, parts are transparent, and therefore the failure rate due to dents is high, and the yield of some parts is low, such as 50%-60%, and resulting in an increase in manufacturing costs

Abstract

An in-mold forming device includes: a first mold and a second mold for injection molding, and a film feeding mechanism for supplying an in-mold foil between the first mold and the second mold. A transfer foil is formed on the in-mold foil. The in-mold forming device also includes: a mold closing mechanism for closing the first mold and the second mold, thereby fixing the in-mould foil in the cavity formed between the first mold and the second mold; a resin injection molding mechanism for injecting resin into the cavity, thereby integrating the transfer foil formed on the in-mold foil with the resin; device. The charger includes a charging unit for releasing ions and charging the particles in the adjacent area of ​​the inner foil, and electrodes for absorbing the particles charged by the ions.
