Provided is a method for manufacturing a microneedle array in which the distal end of a needle-like recessed portion is reliably filled with a drug solution. The problem is solved by a method for manufacturing a microneedle array, including: a positioning adjustment step of adjusting positioning of a mold having a needle-like recessed portion on a front surface, and a drug solution ejection nozzle which ejects a drug solution; a relative movement step of moving the mold and the drug solution ejection nozzle relative to each other to cause a position of the needle-like recessed portion and a position of the drug solution ejection nozzle to coincide with each other in a plan view in a direction parallel to an ejection direction of the drug solution; an ejection step of ejecting the drug solution from the drug solution ejection nozzle toward the needle-like recessed portion; and a suction step of suctioning a rear surface of the mold.

Provided are a production method of a mold having a recessed pedestal pattern for preventing a liquid flow and a manufacturing method of a pattern sheet. A production method of a mold having a recessed pedestal pattern, has: a step of preparing an insert mold having a protruding needle pattern group; a step of preparing a mold having a first mold provided with a protruding pedestal shape and a second mold; a holding step of holding the protruding pedestal shape of the first mold and the protruding needle pattern group of the insert mold in an overlapping manner; a clamping step of performing clamping with the first mold and the second mold to form a cavity; and an injection step of filling the cavity with a resin.

A mould tool (100) is provided which has a multipart mould layer assembly (200; 300; 400; 500; 600) which may either be formed from a carrier (202; 302; 402; 502) and an insert (206; 306; 406; 506) defining a mould profile, or a mould face component (602; 702) having a plurality of stackable blocks (630, 632, 634) which can be assembled to form a mould layer.

In one embodiment, a gate insert includes an injection gate body having front and rear opposite sides and an aperture extending through the injection gate body between an injection gate outlet on the front side and an opening on the rear side. The injection gate body is connectable to and disconnectable from a gate pad in a cavity plate from a front side of the gate pad and from a front side of the cavity plate. In another embodiment, a cavity flange includes a molding body defining at least a portion of a molding cavity shaped to mold a shell of a closure for a container. The molding body is connectable to and disconnectable from a gate insert in a cavity plate from a front side of the gate insert and from a front side of the cavity plate. Other apparatuses are disclosed.

Injection-moulding mould configured for being mounted in an injection-moulding apparatus for automated moulding of work pieces from plastics, said injection-moulding mould comprising at least two separate mould parts that are separated by a mould separation face, and wherein at least one mould part 1 is configured with an outer frame 2 in which one or more spaces is/are configured that are open relative to the mould separation face, in which is mounted at least one exchangeable mould insert 3, and wherein the exchangeable mould insert 3 has a mould cavity side that faces towards the mould separation face, which mould cavity side is provided with one or more mould cavities, and wherein, in the mould insert 3, a set of cooling channels 14 is provided and at least two pipe couplings to which there is, for each pipe coupling, configured a cooling pipe 4 being, with its first end, mounted to the pipe coupling and extending therefrom, in its longitudinal direction, from the pipe coupling and out through a channel 8 in the outer frame of the mould part and to its other end. The cooling pipe being secured in the channel in such a manner that it cannot be shifted in the longitudinal direction thereof, it is accomplished that the pipe coupling may be configured such as to occupy only very little space in the mould insert 3.

A footwear article forming process, and a device for the same are disclosed. The process includes: providing a forming mold set including an outer modular mold, an inner formation mold, and a footwear-forming space therebetween. The footwear-forming space comprises a footwear lower portion forming space and a footwear main portion forming space. Footwear article forming steps are as follows: injecting a pre-determined amount of a footwear main portion rubber material into a footwear main portion sprue channel, the footwear main portion rubber material being injected from a footwear main portion rubber injection opening into the footwear main portion forming space via a transfer injection channel; and placing a footwear lower portion rubber material into the footwear lower portion forming space.

In one embodiment, a gate insert includes an injection gate body having front and rear opposite sides and an aperture extending through the injection gate body between an injection gate outlet on the front side and an opening on the rear side. The injection gate body is connectable to and disconnectable from a gate pad in a cavity plate from a front side of the gate pad and from a front side of the cavity plate. In another embodiment, a cavity flange includes a molding body defining at least a portion of a molding cavity shaped to mold a shell of a closure for a container. The molding body is connectable to and disconnectable from a gate insert in a cavity plate from a front side of the gate insert and from a front side of the cavity plate. Other apparatuses are disclosed.

An injection mold, in particular for encapsulating rotors of electric machines, has a mold, wherein the mold has an arrangement of mold segments. The arrangement forms, along a longitudinal axis, a cavity for a component to be arranged. An exchange unit is provided, which is designed to remove at least one mold segment from and/or insert at least one mold segment into the arrangement, with the result that a size of the cavity can be changed.

A method and apparatus for forming a part having a cavity with a complex contour is presented. The molding apparatus comprises a mold cavity and a molding insert. The mold cavity is formed by a first mold portion and a second mold portion. The molding insert is within the mold cavity, wherein the molding insert has a forming surface, and wherein the molding insert is configured to move in more than one direction relative to the first mold portion.
