摘要： A process of manufacturing the optical discs by injection molding includes compulsive forced cooling of the molded discs, carried out after sputtering to shorten the cooling time in the mold, in consideration of keeping the replication errors in the pits on the molded discs. The process also includes metallizing the surface of the molded discs by sputtering (to make laser beams reflect). UV resin coating for protecting the metallized surface of the discs, and inspecting the pits for replication of information signals quality.

摘要： A mold for molding digital data discs has interchangeable stampers. An outer peripheral stamper retainer and a mirror block with a convex portion allow interchange without dismounting the mold. The outer stamper peripheral retainer has a plurality of arcuate slots connected or disconnected to a plurality of rods provided with a stationary half-mold and to a corresponding plurality of holder bushings and a mirror block with a convex portion whose diameter fits an inner diameter of the outer stamper peripheral retainer. The outer stamper peripheral retainer and the mirror block correspond in size with a disc to be molded.

摘要： A vacuum hot platen press for pressing laminated boards includes a seal cover assembly for keeping the internal process chamber airtight. The seal cover assembly is fixed in an airtight manner to a cylinder plate located below the platens, through which the pressure cylinders extend in an airtight manner. The upper end of the cover assembly is in sliding airtight contact with the tensile strength members of the press. The sliding contact prevents elongation of the tensile members under pressing force, or vacuum forces on the cover assembly, from causing distortion or breakage.

摘要： A mold for molding disk substrata is capable of changing a set position of a stamper plate on a mold cavity. A pair of mirror plates are respectively for forming the surface of a disc cavity or for back stay of stamper plate. The set position of mounting the stamper plate is capable of being performed due to changing selectively the set position of the mirror plate. An inner stamper holder and stamper plate are held on the mirror plate by vacuum force to admit setting operations to ease.

摘要： An injection mold for disc molding such as in the manufacture of video or audio discs. The mold has a stamper removably clamped to one mold half by a rotating stamper holding ring. Both mold halves contain a plurality of clamping pins which selectively engage and hold slots in the holding ring. By rotating the holding ring, disengagement of the ring with the pins of the mold half carrying the stamper occurs simultaneously with engagement of the ring with the pins of the other mold half. Thereby, the stamper is released and may then be replaced.

摘要： A mold is for molding DVD discs to be joined together, back-to-back, to make a single disc. The mold includes a movable moldhalf and a stationary moldhalf. On one of the half-molds an inserting block extends a small distance into the mold cavity, so that the central part of the cavity is thinner than the outer part. The inner part and the outer part correspond approximately to the outer information band and the inner portion of the disc which is grasped. The mold is preferably used in a method using first a lower compression force during resin injection and then an increased force.
摘要翻译：模具用于将DVD盘成型为背对背地连接在一起以制成单个盘。模具包括可动模具和固定模具。在半模中的一个模具上，插入块在模腔中延伸一小段距离，使得空腔的中心部分比外部部分薄。内部部分和外部部分大致对应于外部信息带和被抓握的盘的内部部分。模具优选用于在树脂注射期间首先使用较低压缩力然后增加的力的方法。
