The invention relates to a method for producing a lens element (2), in particular for illumination purposes, in particular for producing a headlight lens (2) for a vehicle headlight, in particular for a motor vehicle headlight (1).

The object of the invention can be a method of manufacturing a product in the form of a sandwich comprising a core and outer layers. The outer layers may be composed of composite material comprising a fiber-reinforced polymeric matrix. The method uses an insert of heat-resistant material, for example silicone. The object of this invention can be to provide a method of manufacturing a sandwich that dissociates the choice of material of the core of the sandwich from the choice of the material of the outer layers.

A cooling and retaining pin (1) for cooling, by air blowing, and retaining, by air suction, a plastic preform, the pin comprising a body (2), defining a longitudinal axis and having a first opening (5) at a first end thereof, coaxial to said longitudinal axis and adapted to be connected to a handling station; a movable element (3) adapted to slide at least partially inside said body; at least one air passage gap provided at a second end of the body or at said first end; wherein the movable element (3) is adapted to move from a first position, to which a first air passage section corresponds, to a second position, to which a second air passage section corresponds, which is smaller than said first section, so as to adjust a blowing air flow during the cooling step and a suction air flow during the step of retaining the preform.

A resin molding method includes a first step of supplying electricity to and heating a stator coil via a stator terminal in a state that the stator terminal clamped; and a second step of molding an insulating resin at a coil end of the heated stator coil. The first step places the stator terminal on a conducting terminal block in such a state that clamping of the stator terminal by the conducting terminal block and a terminal holding member is released, before supplying electricity to the stator coil, and lifts up and down the conducting terminal block, such that the portion of the stator terminal becomes within a predetermined range.

A cap (1) for a container comprises: a body (2), configured to be coupled and uncoupled relative to the neck of the container and including an internally threaded side wall (21), which extends around a longitudinal axis (A), and a transverse wall (22); a tamper evident ring (3), including a retaining element (31), configured to engage a locking member on the neck of the container, and a joining portion (32), where the tamper evident ring (3) is joined to the cap body (2), the joining portion (32) being configured to be torn along a perimeter surrounding the longitudinal axis (A) in response to a movement of the body (2) away from the tamper evident ring (3), wherein the cap (1) comprises a connecting window (4) including a connecting band (40) and a film (400) which is thinner than the connecting band (40).

A method for producing an injection-molded body from a molding material containing a poly(3-hydroxybutyrate) resin includes: melting the molding material by heating the molding material to a temperature between a melting point peak temperature and a melting point peak end temperature in differential scanning calorimetry analysis of the molding material, wherein the difference between the melting point peak temperature and the melting point peak end temperature of the molding material is from 10 to 70° C.; injecting the molten molding material into a mold having a temperature of 30 to 80° C.; and cooling the molding material in the mold to crystallize and solidify the molding material.

The present invention relates to monolithic intravaginal rings comprising progesterone, methods of making, and uses thereof. The intravaginal rings comprise progesterone, a polysiloxane elastomer, and a pharmaceutically acceptable hydrocarbon or glycerol esters of a fatty acid.

The present invention is a method that enables continuous injection molding of a thermosetting resin composition and reuse of an unnecessary part produced during the molding. The method includes injecting a thermosetting resin composition into a mold while a curing reaction of the resin composition is incomplete. The thermosetting resin composition is then cooled in the mold until becoming semi-cured and removed as a semi-cured product from the mold. The semi-cured product is separated from the unnecessary part and separately heated to progress a thermosetting reaction of the thermosetting resin composition. The unnecessary part may be used as a reworked raw material by regrinding the unnecessary part and mixing it with a fresh thermosetting resin composition. Then, a resultant mixture is used to perform a new injection molding.

A reusable mold for injection molding and molding method includes a reusable mold member, a mold cavity defined in the mold member, and at least one heat sink recess defined in the mold member for accommodating a heat sink material therein for rapidly removing heat from the mold cavity when the mold member is used to injection mold a molded part. The reusable mold injection molds a molded part and rapidly removes heat from the mold cavity via a heat sink material accommodated in the at least one heat sink recess.
