Provided are a microneedle template including: a substrate on which at least one microneedle shapes are formed; and a diamond layer formed on the surface of the at least one microneedle shapes, a method for preparing the microneedle template, a microneedle prepared using the microneedle template, and a method for preparing the microneedle.

An extrusion head having a perforated plate of a granulating system. The extrusion head can have a head part and a perforated plate with a perforated-plate wear insert, a perforated-plate main body, a central inflow cone, an inflow cone part, a plurality of nozzle channels, a plurality of perforated dies, and at least one corrosion protected fastener. The perforated-plate can be detachably fastened to the head part. The head part can have at least one central melt channel into which the inflow cone part projects and distributes a melt flow among nozzle channels which can be arranged in the shape of a ring and among the perforated dies which can be arranged in at least one ring. The at least one fastener can be positioned in a central region of the at least one ring of the perforated dies.

A low mass staking module includes a punch having a cavity on a first side, a contact surface on the second side opposite the first side, and a circular flange extending about an outer edge thereof, the punch formed of a thermally-conductive material, an annular housing engaged with the punch about the circular flange at a first end, and a heating element located inside the annular housing. The heating element has an output side in contact with the contact surface of the punch, the contact surface having a shape conforming to a shape of the output side of the heating element. The punch is desirably a low thermal mass punch, while the heating element may be a high power (watt) density, solid state, ceramic, resistant heating element (e.g., aluminum nitride or boron nitride heaters).

Provided are extrusion tools such as extrusion dies or portions thereof having a surface with at least one coating thereon, and methods of forming the same are disclosed. The at least one coating is formed from a composition that is a metal aluminum nitride or carbonitride with particular characteristics such that the amount of aluminum varies within the coating between a coating outer surface and an intermediate thickness within the coating. The resulting coatings have tailored physical and performance characteristics that result in improved wear and extrusion performance.

A production machine for the production of collapsible pouches having a fitment. The machine has a fitment sealing station with an impulse sealing device comprising a first jaw and a second jaw and with an actuator device configured to move the first and second jaws relative to one another between an opened position and a clamped position, as well as a cooling device configured to cool each of the first and second jaws. The fitment sealing station is configured to perform an impulse sealing cycle.
