A curable adhesive that is particularly well suited for use in an injection or compression molding operation. The adhesive is based on polymeric resins having carboxylic acid and acrylate ester functionality, such as grafted phenoxy resin, and further constituents such as organic carbonates, blocked isocyanates, catalysts, maleimide compounds, hydride sources, and a carrier fluid. The curable adhesives are particularly well suited for bonding liquid injectable substrates such as liquid silicone rubber, or polyamides to rigid substrates, such as aluminum, stainless steel, or glass.

The disclosure provides an injection molding apparatus, including a mold unit, an injecting unit, and a counter pressure unit. The mold unit is adapted to provide a first cavity and a second cavity. The injecting unit is adapted to inject a first material into the first cavity to form a first molded object. The second cavity is adapted to accommodate the first molded object. The injecting unit is adapted to inject a second material into the second cavity to form a second molded object, such that the first molded object and the second molded object in the second cavity are combined. The second material is a foaming material. And the counter pressure unit is adapted to provide gas into the second cavity to increase the pressure in the second cavity.

The invention entails a silicone mask with replaceable filter element, including an adjustable strap, a silicone seal ring, a mask framework, a filter element, a face shell and a protective shield. The preparation method is to directly put the adjustable strap, the silicone seal ring, the mask framework, the filter element, the face shell and the protective shield one by one in order. The present disclosure has the advantages of convenient use and easy operation. The length of the strap is adjustable, and the silicone seal ring is made of liquid silicone by molding at one time, which has the characteristics of comfortable wearing and good sealing. The filter element is an embedded structure, which is easy to replace in the process of use, and realizes the recycling of other parts of the silicone mask.

Disclosed and described is a hose for attachment to a dispensing cartridge for placement in a peristaltic pump, for stretching over a rotor of the peristaltic pump, and for conveying a medium by external mechanical deformation of the hose. The hose has a length of preferably 20 mm to 200 mm, an internal cross-sectional area of 0.07 to 7.07 mm.sup.2, and a wall thickness of 0.3 mm to 2.2 mm. Thickenings are formed at both ends of the hose and the distance between the thickenings is 40 mm to 100 mm. According to the invention, it is provided that the hose is manufactured by an injection molding process, the inner cross-sectional area has a tolerance of at most ±33%, and the hose is suitable for closing completely when stretched over the rotor with a tension force of 1 to 10 N.

Creating a replica of an anatomical structure. At least some of the example embodiments are methods including: accepting a plurality of pictures of the anatomical structure of a subject; creating an object file that contains an initial model of an outside surface of the anatomical structure; cutting the initial model to a predetermined exterior shape circumscribing the anatomical structure, the cutting creates a positive model of the anatomical structure within the predetermined exterior shape; creating a negative model of the anatomical structure from the positive model; placing a stem tool object on an outside surface of the negative model in relationship to an orifice of the anatomical structure, and thereby creating a final negative model; printing, by way of a three-dimensional printer, the final negative model to create a negative mold; and casting the replica of the anatomical structure using the negative mold.

Silicone-containing light fixture optics. A method for manufacturing an optical component may include mixing two precursors of silicone, opening a first gate of an optic forming device, moving the silicone mixture from the extrusion machine into the optic forming device, cooling the silicone mixture as it enters the optic forming device, filling a mold within the optic forming device with the silicone mixture, closing the first gate, and heating the silicone mixture in the mold to at least partially cure the silicone. Alternatively, a method for manufacturing an optical component may include depositing a layer of heat cured silicone optical material to an optical structure, arranging one or more at least partially cured silicone optics on the layer of heat cured silicone optical material, and heating the heat cured silicone optical material to permanently adhere the one or more at least partially cured silicone optics to the optical structure.
