VERTICALLY ADDED PROCESSING FOR BLOW MOLDING MACHINE

A vertical additive processing system for use with a blow molding machine having a flow head from which a plastic parison is delivered to a mold and producing an article. The system has a servo-controlled accumulation technology (SCAT) unit including (a) an accumulator collecting plastic material when retracted and delivering plastic material when extended, and (b) an actuator directing the accumulator to retract and extend. The system further has a tooling unit including a bushing body adapted to engage the flow head, a distribution ring, a bushing cap, a central aperture defining a main parison flow path, and a distribution channel delivering plastic material received from the accumulator to the main parison flow path. The system still further has a material duct connecting the two units through which plastic material delivered by the SCAT unit is transported to and received by the tooling unit. Also disclosed is a related method.

Hollow molded article

Disclosed is a hollow molded article which has an opening portion communicating with a flow channel and which can be manufactured simply. The hollow molded article includes a panel and flow channels. The panel includes a first resin sheet and a second resin sheet partly welded with the first resin sheet. The flow channels are disposed between the first resin sheet and the second resin sheet, and include connection portions for external connection which are disposed on a peripheral edge of the panel. The connection portions are formed by the first resin sheet and the second resin sheet.

METHOD AND MACHINE FOR PRODUCING A SINGLE-WALLED OR MULTI-WALLED TUBULAR THERMOPLASTIC BODY
20210001533 · 2021-01-07 · ·

In a method for producing at least a single-walled tubular thermoplastic body in a machine, a nozzle head extrudes at least one tubular preform. The preform is expanded to a predefined dimension in a transverse direction and to a predefined shape in an expansion process using an expanding mandrel, the preform remaining open at the top and bottom. When the at least one preform has cooled off, the expanding mandrel is changed into a non-expanded state and the at least single-walled tubular body is removed from the machine.

Capillary transfer pipettes and related methods

A capillary transfer pipette includes a draw tube having a distal end defining a draw tube opening through which liquid is drawn via capillary action, a proximal end, and a lumen. A squeeze bulb is arranged proximally of the draw tube and defines a fluid chamber in fluid communication with the lumen, the squeeze bulb being compressible to dispense drawn liquid from the draw tube. An air vent hole is formed in at least one of the draw tube or the squeeze bulb, and is configured to vent air to facilitate drawing of liquid through the draw tube opening via capillary action. A volume indicating element may be provided on the draw tube, and the air vent hole may be located proximally of the volume indicating element. The lumen may be formed with a first diameter at the proximal end and a differing second diameter at the distal end. Methods of collecting liquid with, and of making, a capillary transfer pipette are also disclosed.

Molding method and molding apparatus for resin molded article
10682804 · 2020-06-16 · ·

A molding method for a resin molded article includes: a step of sandwiching a sheet-shaped resin in a molten state extruded downward by a pair of rollers, and sending out downward the sheet-shaped resin in the molten state by a rotational driving of the rollers so as to allow a first stretching; a step of drawing downward the sheet-shaped resin in the molten state sent out downward so as to allow a second stretching; a step of disposing the sheet-shaped resin in the molten state that is drawn in a side portion of a mold disposed below the pair of rollers; and a step of molding the sheet-shaped resin into a shape conforming to a mold shape by depressurizing a sealed space formed between the sheet-shaped resin in the molten state and the mold and/or pressurizing the sheet-shaped resin toward the mold.

Molding apparatus

A molding apparatus includes: a die provided with a die recessed portion; a core being relatively movable toward a first side and a second side in an axial direction of the die, and forming a flow passage for molten resin between the core and the die; a slider housed in the die recessed portion, having a gap in the die radial direction between the slider and the die recessed portion, the slider being slidable in the die axial direction; and a wall portion forming part of an inner wall in the die radial direction of the die recessed portion, positioned to oppose the core, and extending in such a way that a thickness of the wall portion gradually decreases heading from the first side toward the second side; wherein the wall portion is elastically flexible outward in the die radial direction in a case in which the wall portion is pushed by the molten resin.
