A method for making an improved contact lens with the steps of providing a mold with a space between the top surface and a bottom surface, and positioning a mat in the space of the mold, providing a bead of liquid polymer of predetermined size at a predetermined location on the surface of the mat, pressing the bead of liquid polymer into the mat between the top surface and the bottom surface of the mold to form an optical zone framed by a mat peripheral zone, exposing the optical zone and the peripheral zone with U-V radiation to harden the optical zone into a composite improved contact lens, removing the cross-linked improved contact lens from the mold, processing the peripheral zone surrounding the optical zone to have a fenestration surface having holes, the holes being through holes with predetermined diameters selected to pass larger proteins, lipids, metabolites.

The disclosure relates to a dipping former, to a process for producing the dipping former and to the use of the dipping former in a latex dipping process. The dipping comprises (i) a molded core part, and (ii) a dipping former shell having a surface in one piece. The dipping former is obtainable by a molding process comprising the following steps: —providing a first cavity and a second cavity; —injection molding or blow molding a first material into the first cavity thereby forming a molded core; —transferring the molded core form the first cavity into the second cavity; and —injection molding of a second material into the second cavity thereby overmolding the molded core, or at least a part thereof, with the second material.

Provided is a resin for core used for injection molding, with which an inner surface of an outer molded body is less likely to be roughened, and an inner surface of a finally obtained molded body is smooth and less likely to have chipping. The resin for core includes a polyvinyl alcohol-based resin, used for an application in which a core is dissolved in water after an outer molded body is molded in an injection molding process, and includes an easy stripping agent that enhances easy stripping properties when the resin for core dissolves in a proportion of more than 0.1 wt % and less than 1.2 wt %.

A mold assembly for producing a part includes a first section, a second section movably coupled to the first section, and a cavity defined by the first section and the second section, the cavity being shaped to receive a part while the first section and the second section are movably coupled to each other. The mold assembly includes a joint formed by adjacent surfaces of the first section and the second section and a seal extending along the joint.

The invention relates to a reversible microfluidic chip comprising at least one lower part and at least one upper part configured to come into contact with said lower part and to close said chip, said lower part and/or said upper part comprising a microfluidic structure, and said upper part comprising at least one layer of a flexible epoxide polymer material and at least one layer of a rigid epoxide polymer material, at least one part of the flexible layer being directly in physical contact with the lower part of the chip when said chip is in the closed configuration, to the method for the fabrication thereof, to the use of said upper part in a reversible microfluidic chip, to said upper part for producing said chip, and to the uses of said chip in various applications.

A polymer mold insert (2) for an injection molding tool (5), the polymer insert (2) comprising an insert body part having an outer shape adapted for insertion into an insert cavity (7) arranged in the injection molding tool (5), and where the insert body part comprises at least two different polymer materials having different physical characteristics and being distributed within the insert body so that one or more first volumes (8) of the insert body comprises a higher concentration of a first one of the two different polymer materials than in the remaining parts insert body, and so that one or more second volumes (9) of the insert body comprises a higher concentration of the second one of the two different polymer materials than in the remaining parts of the insert body part.

A mould (1) for forming spacers made of medical bone cement is described, comprising a female half-shell (11), provided with a hemispheroidal concavity (13) and a male half-shell (12), provided with a hemispheroidal convexity (14) and insertable in the concavity (13), to define with it an internal space for forming the spacer which has an acetabular shape.

A method for manufacturing a molding mold used in an injection molding apparatus includes: generating a first plasticized material by plasticizing a first shaping material containing an amorphous metal and a resin; and shaping a laminate that is a part of the molding mold by discharging the first plasticized material toward a stage to laminate a layer.

A system cures and manufactures a partially-cured tire assembly. The system includes an annular hub member slid into a corresponding annular, radially inner surface, a plurality of elongate spacer members for maintaining corresponding uniform cavity dimensions by fastening the spacer members to the hub member with flap members thereby enclosing a radially outermost surface of each of the spacer members, a first annular curing platen for axially securing the hub member and spacer members relative to each other, a second annular curing platen for axially securing the hub member and spacer members relative to each other; and a plurality of elongate inserts.
