摘要：

An improved moulding method and device which will ensure an accurate, constant shot weight of the dosage of molten plastic material being injected into the mould cavity, thereby to obtain substrate discs having a non-varying thickness. The method of the present invention comprises the step of sensing an actual, secondary rear end position of a moveable wall obtained shortly after the interruption of the supply of molten plastic material to a metering chamber, and then performing a forward stroke of said wall with a predetermined length, whereby an accurately metered constant dosage of molten plastic material will always be injected during each shot. The device includes a means for sensing an actual, secondary rear end position of the moveable wall, and a means for obtaining a predetermined length of the forward stroke of the moveable wall, thereby to inject an accurately metered constant dosage of molten plastic material during each shot.

摘要（中）：

一种改进的成型方法及装置whichwill确保熔融塑料材料的剂量的精确，恒定的喷射重量被注入到模腔中，从而获得具有非变化的厚度的基材的光盘。 本发明的方法包括熔融塑料材料的供应到计量腔室的中断后不久获得的可移动壁的实际，仲后端位置的感测的步骤，然后用一个执行所述壁的向前行程 预定长度，由此准确地设定熔融的塑料材料的计量恒定剂量将总是每次拍摄期间被注入。 该设备包括用于所述可移动壁的实际，仲后端位置的感测装置，以及用于获得所述可移动壁的向前行程的预定长度的装置，从而注入到精确地设定各期间熔化的塑料材料的计量恒定剂量 拍摄。
