Method and apparatus of treating a disc plate |
摘要 |
<p>A method of treating a disc plate. has the following operations of: molding a mold disc plate through an injection molding; and spinning the mold disc plate at a high spin speed. The spinning operation has at least one of the following two sub-operations of: reducing a warp of the mold disc plate with a centrifugal force caused during the spinning operation, and reducing a temperature of the mold disc plate during the spinning operation. Moreover, an apparatus of treating a disc plate has: a conveyer for conveying a mold disc plate obtained through an injection molding; a disc bench for receiving the mold disc plate conveyed with the conveyer; and a spin driver for spinning the disc bench when a temperature of the mold disc plate is higher than 90 DEG C, to thereby spin the mold disc plate. <IMAGE></p> |
