A micro moulding machine and process for forming small plastic parts for the medical device industry. The machine adds heat in two steps to a precision sized plastic pellet and then displaces the entire pellet volume into the mould cavity. A substantial amount of heat is added to the pellet by forcing it through an orifice very near the gate of the mould. The pneumatic pressure to drive the pellet through the orifice is controlled to regulate the amount of heat introduced into the pellet.

A microlens array includes a plurality of optical systems. Each of the optical systems includes a pair of an incidence-side lens portion and an emission-side lens portion. A hollow portion is provided between an incidence surface of the incidence-side lens portion and an emission surface of the emission-side lens portion. The hollow portion includes a first surface extending to a focus position of the emission-side lens portion, and a second surface extending from the first surface toward the incidence surface. A cut line forming portion is formed by a boundary portion between the first surface and the second surface.

Provided are a micro-needle patch and a manufacturing method thereof. The micro-needle patch includes: a support on one surface of which grooves are formed; a gel membrane for delivery of a transmitter to be transferred in which the grooves are filled with a mixture of the transmitter with a biodradable resin, the mixture being in a gel phase; a plurality of micro-needles projected on the other surface of the support and for penetrating the skin; a first protective film that covers the gel membrane and is adhered on the support; and a second protective film that covers the plurality of micro-needles and is adhered on the other surface, wherein passages are formed by being penetrated from the support to each of the plurality of micro-needles or formed by penetrating the support between the plurality of micro-needles, so that the transmitter of the gel membrane is transferred to the skin.

In one or more embodiments, micro light guides are constructed that include a wall and one or more features extending from or protruding into one or more surfaces of the wall. The microstructure light guide is defined by a mold and formed as a single article with uniform internal stresses. In at least some embodiments, the mold that defines the microstructure light guide employs pixelated mold portions that enable selective temperature adjustment of discrete regions of the mold portions to form the microstructure light guide.

An encapsulation method of electronic components comprises steps as follows: preparing electronic components with cylindrical bodies wherein a cylindrical body has front and rear ends made of metals and a middle end made of ceramics and the front end or the rear end features an outer diameter greater than the middle end of the cylindrical body; preparing a mould consisting of upper and lower moulds; encasing the cylindrical bodies inside the upper and lower moulds, injecting heated and softened protective materials into the mould in which protective materials as protective layers are coated on the cylindrical bodies; injecting the cylindrical bodies removed from the upper and lower moulds into a roller in which excessive protective layers on the front and rear ends of the cylindrical bodies are de-coated.

An article having at least one microneedle (160, 260) is provided. The microneedle includes a base (162), an elongated body (161) having a central axis (130) and a body diameter (168), a tip portion (166), and a hollow channel (170). The a tip portion includes a tip (164), a first bevel face (140) oriented diagonally with respect to the central axis and extending through at least 75% of the body diameter, a second bevel face (146) oriented substantially perpendicular to the central axis and intersecting the first bevel face, and a bevel opening defined by a first edge (174) of the first bevel face and a second edge (176) of the second bevel face. The hollow channel extends axially into the body from the bevel opening (172).

A semi-finished product and a method for manufacturing a semi-finished product having at least one micro-component, which method uses a multi-component injection molding process, are disclosed, in which at least one mold chamber of an injection mold is provided with at least one lost part made of a first material, more particularly an injection-molded plastic material, and in another step for producing the micro-component, a second material, which is different from the first material and is elastomer-based, more particularly silicone-based, is injected, as a result of which a firm and form-fitting connection forms between the micro-component and the lost part. In order to be able to achieve advantageous cycle times in a risk-free way, it is proposed for the lost part to be embodied as a macroscopic object holder for the micro-component to permit manipulation of the semi-finished product and for the mold chamber to be provided with this lost part.

The invention relates to a nozzle for use in a device for administering a liquid medical formulation, to a method for producing the nozzle in the form of a microfluidic component and to a tool for producing microstructures of the microfluidic component. The nozzle is formed by a plastics plate with groove-like microstructures which are covered by a plastics cover on the longitudinal side in a fixed manner. The production method includes a moulding process in which a moulding tool is used, which moulding tool has complementary metal microstructures which have been produced from a semiconductor material in an electrodeposition process by means of a master component.

A method of manufacturing a microfluidic device comprises molding a substrate using a master die having at least one outer stepped formation; and forming at least one microstructured formation having an outer rim, the depth of the outer rim being shallower than that of the microstructured formation.

An injection molding apparatus includes a substantially circular first substrate, a substantially circular second substrate disposed to face a surface of the first substrate, a fixing member which fixes a peripheral end portion of the first substrate and a peripheral end portion of the second substrate, and an injection portion which is provided in the fixing member and from which a composition is injected into a gap between the first substrate and the second substrate, in which a space connecting with the injection portion and the gap is provided in at least a part of a periphery of the gap, and a width of the space in a thickness direction is larger than a width of the gap in the thickness direction.
