摘要： Optical qualities of a production lot of base material used in the fabrication of semi-finished lenses may be accurately determined by employing chipper plate samples produced from the base material in accordance with aspects of the present invention. In various implementations of the present invention, the chipper plates samples may be fabricated by subjecting base material to an extended cycle time and temperature profile using a mold having cavities of different thicknesses. The resulting chipper plates provide an improved indication of the color of semi-finished lenses molded from the production lot as well as an improved indication of resin stabilizer defects that may be utilized during a pelletizing process to control and enhance the quality of a production lot. Furthermore, the chipper plates may be provided by suppliers as samples of a production lot to enable customers to base purchasing decisions on a reliable and accurate measure of optical properties.

摘要： A method of adjusting the position of a part-forming surface of an insert (20) relative to an injection mold parting line; an inserted assembly is provided comprising an insert (20) having an internal channel (22) for circulating thermal control fluid therethrough and a no-leak valve (30) which can be opened over a distance L.
The position of the insert (20) is adjusted by shimming the insert (20) relative to a support surface of the injection molding machine.
In this way, distance adjustments less than L can be implemented without changing the valve (30) so that one insert assembly can be used at multiple positions relative to the parting line of the injection molding machine.

摘要： A method of infusing a dye into the surface of an article formed of a plastic material comprises contacting the surface with a solution including one or more solvents each aggressive to the plastic material, one or more dyes and one or more substances each capable of plasticizing the plastic material. If the plastic material is polycarbonate, then the aggressive solvent may be one or more chlorinated hydrocarbons. The dye may be a photochromic dye, a cosmetic tinting dye, dyes for absorbing infrared, laser and ultraviolet radiation, or combinations thereof. A wide range of plasticizers has been investigated. The article is contacted by the solution for ten seconds to one minute; and nearly all the infused solvent is then evaporated from the article by heating. The use of one or more plasticizers reduces or eliminates bubbling or hazing of the contacted surface during solvent evaporation. The dyed article comprises a surface layer having a depth of the order of magnitude of 100 microns containing one or more dyes, one or more plasticizers and, likely, a trace amount of the one or more aggressive solvents.

摘要： A hardware configuration and related method for straight injection molding of ophthalmic lenses using thermal control fluid circulating within a closed channel located interior of the insert. The channel is closed by a no-leak valve. The adjusting body is equipped with a mating no leak valve. The valves seal over an operational distance L before the valves are opened to admit the thermal circulating fluid into the insert. The insert can be easily changed or shimmed without leaking and without having to change the insert configuration.

摘要： Methods are disclosed which decrease the time between de-molding a lens and initiating a hard coating process. The de-molded lens at a de-mold temperature TM is transported away from a mold. A dip tank is maintained at a temperature TD, where TD is less than TM , wherein the dip tank includes a liquid including a primer or a hard coat solution. The lens is dipped into the dip tank wherein the lens has a temperature TL greater than TD, so that intermediate cooling, cleaning, destaticizing and delays associated therewith are avoided. Other methods eliminate many conventional process steps and may include drying raw material to decrease primer coating times and employing robotic systems for carrying out the methods.

摘要： A method of making photochromic thermoplastic wherein the material is extruded into a length or lengths having at least one relatively small cross-sectional dimension. The length or lengths are treated with a solution of photochromic dye dissolved in a solvent, for example, cyclohexanone, which attacks the material. The length or lengths have a surface area-to-volume ratio sufficiently large to absorb an effective amount of the dye at their surface or surfaces. The length or lengths are dried to evaporate the solvent. The length of lengths are heated during the treating and drying steps. The dried length or lengths are cut into smaller pieces which may be introduced directly into a molding machine to form photochromic articles. Where a plurality of lengths are provided, the surfaces thereof are maintained separated from one another during the treating and drying steps.
