In an injection molding system, an insert formed with a cavity or an insert member for molding an insert-molded article is shot by a camera, and the insert or the insert member to be inserted into a mold is identified based on a characteristic of the insert or the insert member shot by the camera and previously stored data on the insert or the insert member.

In order to calculate a ball screw abrasion amount of an injection-axis ball screw or a mold-clamping-axis ball screw, a position of a ball nut fitted to the ball screw is photographed by a camera installed in an injection molding machine. Then, if the photographed position of the ball nut is found, as a result of analysis of an image captured by the camera, to be deviated from the position of the ball nut when a ball screw has no abrasion, it is determined that the ball screw is abraded.

In an injection molding system, bolt position related information recognizing unit which recognizes an attachment position of a bolt for each attachment is provided. Based on the attachment position of the bolt, or the attachment position of the bolt and a phase of the bolt stored in the bolt position storage unit, bolt attaching and detaching unit attaches and detaches the bolt to and from the attachment. Thus, even if the position of the bolt varies in accordance with the attachment, it is possible to attach and detach the bolt by recognizing the attachment position of the bolt.

Types of molded articles carried by a carrier are identified and the molded articles are sorted based on image-related information for the molded articles molded based on set operating conditions for injection molding machines and molded article images acquired by an image acquisition unit. It is thus possible to narrow down candidate images in processing in a molded article identification unit, thereby making it possible to construct an injection molding system that has excellent production efficiency with a reduced load on processing in the molded article identification unit.

In an injection molding system, a compression ratio of an image acquired by a molded article image acquisition means is changed based on a physical quantity related to injection molding and stored in a storage means. Thus, an image of a molded article is compressed and stored according to the compression ratio obtained based on the physical quantity.

A method for producing a component, and an injection-molding device. In the method, the following steps are carried out, in particular in succession: closing an injection mold, injection molding a base body by introducing a first plastic material into a first injection-molding cavity, opening the injection mold, stamping one or more first film elements and removing the component from the mold.

The inspection apparatus includes: a linear polarizer and a wave plate generating polarized light from light emitted from a light source; a polarization camera imaging the polarized light generated by the linear polarizer and the wave plate and transmitted through a molding product; and a determination unit determining a state of the molding product using an image captured by the polarization camera.

A method of reducing or limiting tissue adhesion comprises contacting the tissue with an effective amount of a hydrogel composition comprising: 2% to 6% by weight hyaluronan, and 3% to 18% by weight methylcellulose, wherein the combined total amount of hyaluronan and methylcellulose in the hydrogel is between 8 and 24% by weight; and wherein the ratio of hyaluronan:methylcellulose is between 1:1 and 1:5 w/w. The hydrogel composition and may be used to reduce or limit tissue adhesion that is correlated with surgery, and may be used in surgeries wherein the surgery is performed through a small incision or opening.

A silicone pencil preparation device includes: a conveying apparatus, a grabbing apparatus, a silicone injection molding machine and a control apparatus. The conveying apparatus includes an unprocessed pencil conveying apparatus and a processed pencil conveying apparatus. The silicone injection molding machine includes a main machine provided with a mold and a mold closing system, the mold includes a front mold and a rear mold, the mold is secured onto the mold closing system, and a middle portion of a front mold cavity is provided with a pencil carrying slot. The control apparatus is configured to perform the following steps: moving an unprocessed pencil to the pencil carrying slot; performing a mold closing operation; performing an injection molding operation on the front mold cavity and a rear mold cavity; performing a mold splitting operation; and moving a processed pencil in the pencil carrying slot to the processed pencil conveying apparatus.

A resin intrusion prevention structure for preventing resin intrusion into a heater in a shut-off nozzle, the shut-off nozzle including a nozzle body having an injection flow path, through which resin flows, in an axial direction and a shut-off valve configured to open and block the injection flow path. The resin intrusion prevention structure is provided in a vicinity of a sliding exposed portion, which is exposed to an outer circumferential surface of the nozzle body in a sliding portion, and is configured to prevent the resin leaking from the sliding exposed portion from intruding into the heater provided in the shut-off nozzle.
