The present disclosure relates to systems, apparatuses, and methods for assembling cartridges for aerosol delivery devices. The cartridges may be assembled by coupling a base of the cartridge to a carriage that is transported via a track. The track transports the carriages between various substations at which one or more parts are added to the base. The carriage may be lifted from the track by a lifter mechanism at each substation in order to perform assembly operations on the base. An inspection system may inspect the cartridges at various stages of completion at or between the various substations.

A method includes the steps of: a) providing a needle bed body and insertion sheets, wherein the needle bed body is provided with slots, the needle bed body has a first datum plane and a second datum plane, each insertion sheet has a first and second portions at two ends thereof and corresponding to the first datum plane and the second datum plane; b) measuring sizes of the inserting sheets and the bottom of the slot and milling each slot when needed; c) measuring sizes of the first datum plane and second datum plane and machining the first and second datum planes when needed; and d) inserting the insertion sheets into the slots with making the first and second portions attached on the first and second datum planes, respectively.

A filter cell element for use in a housing to form a filtering assembly. The filter element has a media pack having an interior and a separator element having a passage therein for radial fluid communication between the media pack interior and an edge of the media pack. An overmold seal at the media pack edge seals the media pack to the separator element. Methods of making the filter element and methods of using are also disclosed.

A high aspect ratio in-plane metal microneedle array, a manufacturing method and a clamping and inserting auxiliary device thereof is disclosed. A large-size metal sheet is cut into small metal sheets. A clamping tooling composed of two upper and lower metal cover plates is processed. Inner sides of the upper and the lower cover plates of the tooling are provided with grooves in which the metal sheets are placed and fastened by bolts. Wire cutting is conducted on the tooling and the metal sheets as a whole to obtain a plane metal microneedle array with a plurality of microneedle bodies. In addition, an assembling and clamping device and an inserting auxiliary device of the high aspect ratio in-plane metal microneedle array is provided. The assembled inserting auxiliary device is placed on skin, and the microneedle array is inserted into the skin through the auxiliary device.
