Provided is an injection mold and a method of injection molding having a molding core system. The molding core system including a plurality of co-operable components manipulable between a first molding position at which the core system is fully deployed and a second position in which the core system is configured to axially retract and radially contract into a second drawing position, the outer shape of said core system being substantially complementary to the inner shape of the molded article.

An inkpad holder for arrangement in an insertion compartment of a self-inking stamp includes a one-piece body having a bottom and walls projecting therefrom which delimit a receiving space for receiving an inkpad. At least one wall of the inkpad holder has a retaining web protruding into the receiving space in order to retain the inkpad, the retaining web extending over the entire length of the wall.

Disclosed is an injection molding method for a degradable intravascular stent with a flexible mold core structure. The injection molding method includes the following steps: Step 1, winding a metal rod with a flexible metal film, and applying an inward bending stress to the flexible metal film; Step 2, fixing the flexible metal film to the metal rod, and processing a complementary structure of the degradable intravascular stent on the surface of the flexible metal film; Step 3, performing injection molding processing: Step 4, ending the injection molding, removing the mating body of the flexible metal film and the metal rod and the degradable intravascular stent formed on the surface of the flexible metal film by injection molding, performing cooling, separating the metal rod from the flexible metal film, withdrawing the metal rod, and then removing the flexible metal film to obtain a formed degradable intravascular stent.

A liftgate (28) formed with a thermoplastic which is overmolded around preselected reinforcements at stress points, such as a corner area, which includes a pair of separate reinforcement plates (14,18) and wherein a 3-dimensional reinforcement plate (12) is connected between the pair of separate reinforcements (14,18). Preferably the 3-dimensional reinforcement plate is connected to three reinforcements.

A device for electromagnetic forming of components having a cavity may include: a core extending along a central axis and configured to be fitted into the cavity to carry out a forming operation on a component; wherein the core may be configured to be pulled out of the cavity after the forming operation, wherein the core may include a plurality of segments in parallel arrangement, wherein the segments may be made of non-conductive material, and wherein the segments may be configured to alternate between a machining configuration, in which the segments are locked together to prepare the core for a machining operation, and an extraction configuration, in which the segments mutually slide to reduce a diameter of the core and to remove the core from the cavity; and drive means for moving the segments, wherein the drive means is configured to alternate the segments between the machining and extraction configurations.

A mold apparatus for molding a rotating member includes: a column mold portion including a first column molding hole extending in a first direction and configured to mold a column portion therein and a first blade molding groove formed as an intaglio on an inner circumferential surface of the first column molding hole to have a shape corresponding to a blade and configured to mold the blade therein, and an extraction guide configured to push a first end of the column portion in the first direction to thereby extract the column portion from the first column molding hole, at least a portion of the extraction guide being positioned inside the first column molding hole. The extraction guide is configured to press the column portion to thereby extract the column portion from the first column molding hole while the column portion rotates in an inclined direction of the blade.
