〔産業上の利用分野〕
本発明は、レコード、コンパクトディスク等を射出成形
する時に用いるスタンパに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a stamper used when injection molding records, compact discs, etc.

品質向上ｔ−０］能にしたものである。The present invention improves the durability of the stamper and mirror plate by applying fixed lubrication to the back surface of the stamper used for injection α-types of records, compact discs, etc., and reducing wear on the mirror plate that contacts the back surface of the stamper. Furthermore, the quality improvement of the stamped product can be achieved.
レコード、コンパクトディスク、あるいは、光メモリー

、ニッケル電鋳を３００μ程度、行った後、表面研摩、
内外径加工により製作される。Stampers used for injection α-type materials such as records, compact discs, or optical memory substrates are electroformed with nickel to a thickness of about 300μ, then surface polished,
Manufactured by internal and external diameter machining.

品に転写されてくるため不良となる。The back surface is polished to a smooth finish with a surface roughness of 0.01B, and is performed to reduce the amount of abrasion with the mirror plate, but since the stamper is nickel itself, the hardness is 11V20.
0 to 300, which is a low 900%, and scratches occur due to friction between the mirror plate and the mirror plate during injection molding, and the scratches become larger during long-term stamping, and at a crossroads, the scratches are used for injection molding. It becomes defective because it is transferred to the shaped product.

が、型の鏡面板材質が、スタバックス等、硬度Ｈ７５０
０程度のものに限定されるため、スタンパの硬度が高く
なると、逆に鏡面板の摩耗がはげしく、コスト高となる
結果になっている。In order to increase the hardness of the stamper, attempts have been made to use nickel-cobalt electroforming and surface hardening treatments, but the mirror plate material of the mold has a hardness of H750, such as Starbucks.
Since the hardness of the stamper is limited to approximately 0, as the hardness of the stamper increases, the mirror plate becomes more abrasive, resulting in higher costs.

−る。[Problems and objectives to be solved by the invention] The present invention:
This invention solves the above-mentioned problem, and aims to improve the durability of the stamper and mirror plate and the quality of graphic products by reducing the wear force between the back surface of the stamper and the mirror plate.
スタンパと鏡面板との摩耗を少なくシ、耐久性を向上さ
せるため、スタンバ裏面に、固体潤滑処理を、はどこし
た事を特徴とする。The stamper is characterized by a solid lubricant treatment applied to the back surface of the stamper in order to reduce wear between the stamper and the mirror plate and improve durability.
本発明によれば、スタンバ裏面と鏡面板の摩擦係数を、
０．３以下と、金属同志の接触の場合より大巾に低くす

、スタンパの寿命を著しく向上させる事が可能になった
。According to the present invention, the coefficient of friction between the back surface of the stand bar and the mirror plate is
At 0.3 or less, it can be made much lower than in the case of metal-to-metal contact, thereby reducing the occurrence of friction scratches and making it possible to significantly improve the life of the stamper.
