A needle-like structure includes projections formed in rows on a substrate and extended in a direction, and needle portions formed on each of the projections such that the needle portions are spaced part from one another.

The present disclosure relates to a tool used to producing anatomical phantoms. The tool includes an inner flexible mold which sits inside a rigid, thermally conductive outer shell. The rigid shell may be made out of aluminum. The silicone mold and thermally conductive shell both include at least two interlocking components. The shell is held together by a locking mechanism which can expand upon internal pressure. An anatomical phantom is produced from polyvinyl alcohol hydrogel by freezing and thawing a PVA liquid precursor in the silicone mold and demolding it.

Provided are a molded foam (1) that is lightweight and can be manufactured at low cost, and can reduce abnormal noise due to friction with a vehicle structure effectively and for a long time, and a mold (10) that can mold a molded foam that is beautiful and attractive in appearance.

Disclosed are methods related to making a stamped article and articles and assemblies made therefrom. The methods include providing a partial replica of the stamped article having opposed first and second major surfaces, and then coupling the partial replica to a walled enclosure to provide a mold assembly having upper and lower chambers separated from each other by the partial replica. Compositions can be hardened in the upper and lower chambers to provide upper and lower tools having a shape complemental to the first and second major surfaces. After removing the upper and lower tools from the mold assembly, a deformable sheet can be pressed between the upper and lower tools to form the stamped article.

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.

The present invention includes producing a preliminary mold (10-1 or 20-1) provided with two-dimensional patterns (111 or 211) having a shape of a microneedle array (30) therein; producing microneedle array molds (10 and 10-2 or 20 and 20-2) having a three-dimensional shape by expanding air inside the patterns (111 or 211) having a two-dimensional shape to deform the patterns (111 or 211) having the two-dimensional shape into molds having the three-dimensional shape; and after pouring a biodegradable resin into the microneedle array molds (10 and 10-2 or 20 and 20-2) and solidifying the biodegradable resin, completing the microneedle array (30) by removing the microneedle array molds (10 and 10-2 or 20 and 20-2), thereby providing a mold for production of a microneedle array and a production method of the microneedle array using the same capable of tightly suturing an affected area without inducing pain.

A functional polymeric cutting edge structure and methods for manufacturing cutting edge structures using polymeric materials are provided. A razor blade for use in a razor cartridge or a blade box for assembly in a razor cartridge frame may be formed using the present invention.

A mold stepped on by a foot includes a seat, a plurality of telescopic rods, an image capturing device and an insole material. The telescopic rods are parallel to each other and are disposed in the seat. The telescopic rods stepped on by the foot generate a plurality of restoring forces, respectively. The image capturing device is disposed on the seat. The telescopic rods are captured by the image capturing device to generate a plurality of three-dimensional data of the telescopic rods. The insole material is disposed below the telescopic rods for molding an insole.

A soft lithography template or stamp is made by casting a polydimethysiloxane (PDMS) or other suitable elastomeric precursor onto a master pattern. The master pattern may be formed utilizing known micro-fabrication techniques. The PDMS template includes an inverse copy of the micro-structures on the master pattern, and can be placed into a mold used to prepare a carbon-fiber reinforced polymer composite part or other polymer molding systems where a matrix material passes through a fluid state during the cure process. The liquid resin material flows into the structures on the surface of the PDMS template and hardens during the curing cycle. After the part is released from the mold, the PDMS template can be peeled from the surface of the part to reveal the free standing micro structures which are a replica of the master pattern.

According to one aspect, a reconditioning wafer can include a carrier substrate that supports at least one array of regularly spaced protrusions configured to form indentations in a support surface of a wafer holding stage. The protrusions within the same array can have substantially the same shape and dimensions, thereby enabling a more reliable reconditioning process compared to prior art solutions. The protrusions may have the form of pyramids or pillars or other similar shapes with at least the tip of the protrusions formed of a material suitable to make the indentations. The reconditioning wafer can be obtainable by a molding technique wherein an array of molds can be created in a mold substrate. The molds can be filled with an indentation material such as diamond, and can be bonded to the carrier substrate. The mold substrate can be removed by thinning and wet etching.
