Hollow microneedle with bevel opening
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), a first channel (170), and a second channel (176). The tip portion includes a tip (164), a beveled surface (140), and a bevel opening (172) in the beveled surface. The first channel extends axially from the bevel opening through at least a portion of the elongated body and has a first wall that is substantially aligned with the central axis. The second channel extends radially from the first channel to the bevel opening and has a second wall that is oriented substantially orthogonal to the central axis. The first channel and second channel merge to form the bevel opening.
TIRE VULCANIZATION MOLD, TIRE VULCANIZATION DEVICE, AND TIRE PRODUCTION METHOD
A tire vulcanization mold disclosed herein includes sectors 13 divided in a tire circumferential direction and molding a tread portion 1 of a tire, and a pair of upper and lower side plates 11 and 12 molding a sidewall portion 2 of the tire. Mold parting lines 16a and 17a formed by the sectors 13 and a pair of the upper and lower side plates 11 and 12 are located in the tread portion 1 and set to pass a bend point 8c of a surface design in the tread portion 1.
TIRE VULCANIZER
A tire vulcanizer is provided which is capable of arranging a sector at a specified position during closing of a mold and suppressing a vulcanization molding defect. The tire vulcanizer includes: the sector that shapes a tread of a tire; paired upper and lower side plates that shape sidewalls of the tire; a segment to which the sector is fixed and which causes the sector to move in a tire radial direction; and mold parting surfaces defined by the sector and the side plates. Mold inner ends of the mold parting surfaces are arranged on the tread, and the mold parting surfaces extend outward in the tire radial direction from the mold inner ends. The sector includes paired upper and lower flange sections which respectively abut the paired upper and lower side plates in a state where the adjacent sectors in the tire circumferential direction tightly contact each other.
TIRE VULCANIZATION MOLD, TIRE VULCANIZATION DEVICE, AND TIRE PRODUCTION METHOD
A tire vulcanization mold disclosed herein includes sectors 13 divided in a tire circumferential direction and molding a tread portion 1, and a pair of upper and lower side plates 11 and 12 molding a sidewall portion 2 of a tire. Mold parting lines 16a and 17a formed by the sectors and the side plates are located in the tread portion 1. A lateral groove molding rib 18 molding a lateral groove 5 in the tread portion is provided to bridge from the sectors 13 to the side plates 11 and 12 and a protrusion molding recess 18a used to mold a protrusion 5a at a groove bottom of the lateral groove 5 is provided to the lateral groove molding rib 18. Mold parting planes 16 and 17 are provided to divide the lateral groove molding rib 18 at a position where the protrusion molding recess 18a is provided.
TIRE VULCANIZATION MOLD, TIRE VULCANIZATION DEVICE, AND TIRE PRODUCTION METHOD
A tire vulcanization mold disclosed herein includes sectors 13 divided in a tire circumferential direction and molding a tread portion 1 of a tire, and a pair of upper and lower side plates 11 and 12 molding a sidewall portion 2 of the tire. Mold parting lines 16a and 17a formed by the sectors 13 and a pair of the upper and lower side plates 11 and 12 are located in the tread portion 1. The mold parting lines 16a and 17a are set within a range PR which accounts for up to 7.5% of a width BW of an outermost belt 5a of the tire on each of an outer side and an inner side than belt end positions BP of the outermost belt in a tire width direction.
MOLDING METHOD AND MOLDING SYSTEM FOR RESIN MOLDED MEMBER
A molding method and a molding system for improving a molding speed of a resin molded member. In the method, firstly a thermoplastic resin composite material is filled in a metal mold (i.e., at time T0), and subsequently a mold-clamping process gets started. As the mold-clamping process progresses, a first decompression circuit starts to decompress an inside of a cavity when the cavity is closed by a sealing member provided on the metal mold. Then, as the mold-clamping process further progresses, the thermoplastic resin composite material thus filled in the metal mold contacts an upper mold of the metal mold (i.e., at time T2). After that, a second decompression circuit starts to decompress the inside of the cavity, thereby to complete the mold-clamping process (i.e., at time T3).
Rotary injection molding apparatus for producing plastic components such as syringes
A syringe includes a barrel having a proximal end, a distal end, and a sidewall extending substantially circumferentially between the proximal end and the distal end along a longitudinal axis. The barrel is formed from an injection molding process including aligning a mold die defining an internal shape of the barrel in a molding cavity defining an external shape of the barrel, the molding cavity defined by first and second mold sections. Each mold section includes at least one gate adapted to control the flow of a molding material into the molding cavity. The gates of each mold section are opened to permit the first and second melt streams of molding material to fill the molding cavity surrounding the mold die, where the molding material takes the shape of the molding cavity.
Method of making a valve system for a valve asembly
An over-molded valve stem for a valve assembly includes a rigid inner member and a unitary elastic cover molded over the inner member. The inner member includes a main section and an arm extending from the main section. The cover includes a main cover portion, an arm cover portion, and an end portion, with the end portion being spaced from the main cover portion by the arm cover portion. The main cover portion is disposed over the main section with the end portion and main cover portion defining diameters that are larger than the diameter of the arm cover portion. The end portion can include an integral seal member for engaging with a bore of the valve assembly. A method of making the valve stem involves molding the cover about the inner member such that a parting line doe not axially extend across sealing surfaces.
