  • Manufacturing process for optical thin film with high hardness made by insert mold technology
    Patent number: 7976742
    Abstract: An optical thin film with high hardness is made by insert mold technology and manufacturing processes thereof. The optical thin film is applied on a surface of a plastic housing for increasing hardness of the plastic housing so as to prevent scratches. During manufacturing processes of the insert mold for producing a hard coating film, the step of hardening treatment is moved to the last step so as to avoid cracks on the optical thin film generated during the procedures. Thus, the yield rate is increased, and the manufacturing cost is reduced.
