摘要： There is described a method for fonning lenses having substantially no optical power. The method includes fonning, via in situ polymerization, a layer of non-uniform thickness of an optically clear, high scratch-resistant polymeric material on the convex surface of the lens. The lenses provided by the method are characterized by having maximum thickness in the central region of the lens and gradually diminishing thickness radially towards the periphery of the lens.

摘要： A method for forming a thermoplastic preform (20) into a lens by compression molding the preform (20) between a pair of molds (10, 12) is provided. The preforms (20) have different radii of curvature and come in different weights. Concave mold halves (12) are provided with different radii of curvature, with the radius of curvature of the preform (20) being greater than that of the concave mold half. The preforms (20) have a convex side for placement in the concave mold half and a substantially flat or concave side for engagement with a convex mold half (10). The preform (20) has locator arms (42) and an indent (52) to ensure proper orientation.

摘要： Hard to fill large-surface-area parts and/or thinwalled configurations of optical lenses and reflective optical elements are among the difficult-to-mold thermoplastic products which require precision replication of the molding surfaces, in micro detail. We combine multiple opposing gates (7) and (8), to reduce the meltflow pathlength, with non-isothermal steps of firstly, heating these mold surfaces (18) and (31), with circulating heat transfer fluids supplied by a hot side supply system, to a temperature setpoint sufficiently high to retard solidification, then secondly, injecting the melt through these opposing gates (7) and (8), then thirdly, rapidly cooling to solidification, by circulating heat transfer fluids of much lower temperature, supplied from a cold side supply system. To run fastest injection molding cycle time, the fast heating phase comes from combining high-thermal-conductivity copper alloy mold cavity materials with very large thermal driving force (high "delta T") from high-heat-transfer-rate fluids (preferably, steam). Fluid control units and electronic process sequence control units are interconnected to govern the flow of these fluids into and out of the injection mold and the supply systems in accordance with the predetermined logic of the process flowsheet. To reduce geometric constrictiveness during filling of the mold cavity, an injection compression process sequence with pre-enlarged variable-volume mold cavity (6) can be created before injection starts, then compressed toward original dimensions during injection.
摘要翻译：难以填充大面积部件和/或光学透镜和反射光学元件的薄壁结构是需要精密复制成型表面的难以模制的热塑性产品。我们结合多个相对的浇口（7）和（8），以通过非等温步骤来减少熔体流动路径长度，首先，加热这些模具表面（18）和（31），使用热侧供应的循环传热流体系统，达到足够高以阻止凝固的温度设定值，其次，通过这些相对的浇口（7）和（8）注入熔体，然后第三次通过循环供给较低温度的传热流体循环而快速冷却至凝固冷侧供应系统。为了运行最快的注塑周期时间，快速加热阶段来自于将高导热铜合金模腔材料与具有非常大的热驱动力（高“delta T”）的高热传递流体（优选地，蒸汽）。流体控制单元和电子处理顺序控制单元相互连接，以根据工艺流程图的预定逻辑来控制这些流体进出注射模具和供应系统的流量。为了减少填充模腔期间的几何收缩，可以在注射开始之前创建具有预扩大可变体积模腔（6）的注射压缩工艺顺序，然后在注射期间被压缩成原始尺寸。

In this casting process, polymerization is effected while a proper motion, for example, a particular rotating motion, rotating motion with the axis of rotation substantially horizontal, and the like is imparted to a shell so that the gravity acting on any minute portion comprising the monomer injected into the shell continuously changes its direction.
