    摘要: A method for manual casting of polymers, is used for production of a molded part. The production of the molded part comprises providing a mold with a cavity, preparing a liquid polymer according to a recipe, manually casting the liquid polymer into the mold and solidifying the liquid polymer in the mold resulting in the molded part. A system comprises the mold and at least one sensor Wherein the system uses parameter data to calculate the recipe. The system comprises an electronic device and a display, wherein the electronic device controls the display. The display shows during the production of the molded part at least a part of at least one production step of the recipe.

    摘要: In an example method of forming an optical film for an eyepiece, a curable material is dispensed into a space between a first and a second mold surface. A position of the first mold surface relative to the second mold surface is measured using a plurality of sensors. Each sensor measures a respective relative distance along a respective measurement axis between a respective point on a planar portion of the first mold surface and a respective point on a planar portion of the second mold surface. The measurement axes are parallel to each other, and the points define corresponding triangles on the first and second mold surfaces, respectively. The position of the first mold surface is adjusted relative to the second mold surface based on the measured position, and the curable material is cured to form the optical film.

    摘要: Provided is a method of manufacturing a microneedle array in which an active ingredient is concentrated at a tip while an active ingredient content is guaranteed. In order to achieve the object, a method of manufacturing a microneedle array in which needle-like recessed portions of a mold are filled with a liquid to form one dose of a patch includes determining a filling amount of the liquid from a difference in mass of the mold before and after filling of the liquid, determining a filling state of the liquid in the mold filled with the liquid, sucking the mold in which the filling amount and the filling state of the liquid are determined to be normal from a rear face, and evaporating and drying a solvent of the liquid of the sucked mold.

    摘要: An apparatus and a method are provided for a latex-based packaging material configured to provide a dust-free alternative to vermiculite packaging materials. The latex-based packaging material comprises a portion of a latex-based waste formulated into a recycled latex emulsion, and a portion of particulate material into which the recycled latex emulsion is mixed so as to form a latex-based pulp. In some embodiments, additional components, such as any of various plasticizers, coloring agents, or hardeners, may be included in the latex-base pulp. The latex-based pulp is dispensed and dried so as to form the latex-based packaging material in a variety of desired shapes. Drying may be accomplished by way of unaided atmospheric evaporation, or by way of various conventional drying methods. In some embodiments, the desired shape of the packaging material comprises latex-based packaging peanuts suitable for separating and cushioning forces between containers during transportation in a larger container.
