摘要:
A vessel is configured to hold a product in an interior region formed in the vessel. The vessel includes an inner layer arranged to define the interior region and an outer layer. The vessel is formed using a blow-molding process in which a multiple layer parison is blow molded to form the vessel. The multiple layer parison is formed in an extrusion process in which a number of extruders are arranged to co-extrude associated inner and outer parisons to establish the multiple layer parison.

Es ist ein Verfahren zum Herstellen und Befüllen von dünnwandingen und/oder unter Wärmeeinwirkung zumindest teilweise forminstabilen Getränkebehältern (12) offenbart, bei dem die Behälter (12) durch Blasformen von Vorformlingen (10) hergestellt, anschließend mit einem flüssigen, heißen Füllgut (16) befüllt, danach mit einem Druckgas (18) beaufschlagt und anschließend verschlossen werden. Die Vorformlinge (10) und die daraus geformten Behälter (12) werden während des Blasformens mit einer Blasformtemperatur beaufschlagt, die im Wesentlichen unterhalb 110 °C liegt.
摘要:
A method for fabricating a stent comprising: radially deforming a polymer tube (301) for use in fabrication of a stent from the deformed tube, wherein the radial deformation propagates along the tube axis as the tube is heated (330) along the axis, the polymer tube having an internal tube pressure (325) higher than ambient; controlling the deformation temperature to provide a selected fracture toughness to a stent fabricated from the tube wherein the temperature is controlled to provide a morphology of the deformed polymer tube comprising an amorphous matrix including dispersed crystalline regions and wherein the crystalline regions have a size less than about 15 micrometers; and fabricating the stent from the deformed tube.
摘要:
A seamless convoluted hose assembly. The assembly includes: a tubular inner liner having an outer surface, an inner surface, and an inner liner wall therebetween which defines a passageway. The assembly further includes a helical coil or a plurality of annular loops which produce convolutions in the outer surface of the tubular liner when the tubular inner liner is forced through the helical coil or plurality of loops under heat and pressure.

An inflatable balloon cuff may be adapted to seal a patient's trachea when associated with an endotracheal tube. These cuffs may include indicia that facilitate attachment of the cuff relative to the tube to reduce manufacturing variability for such characteristics as rotational and length alignment. Such indicia may include protrusions that are formed in the wall of the cuff collars or may include visual indicators, e.g., colorimetric or shape-wise, indicators. Cuffs with improved attachment relative to the tube may have increased sealing performance.

A capsule is formed from a PVA composition by blow moulding. Such capsules can at last provide a viable alternative to gelatin for bio-degradeable capsule containing a pharmaceutical or consumable or other substance, for example a detergent. The capsules may contain solid or liquid substances. Blow moulding apparatus suitable for forming such capsules is also disclosed and claimed

摘要:
A method and mold (10) for manufacturing a vehicle component such as a bumper beam (52) or body panel (62). The component is manufactured by: 1) injecting molten material into a parison cavity of a mold (10) to form a parison (40), wherein the mold has at least two sections (14, 18) that are moveable between a first position defining the parison cavity and an expanded second position defining predetermined blow cavities; 2) retracting the at least two sections (14, 18) to the expanded second position, and 3) injecting a gas into the parison (40) to expand the parison (40) to form blown part (44).
摘要:
A method for obtaining a relatively large-sized blow molded article superior in mold transfer properties such as surface gloss in a short forming cycle with good productivity by a blow molding using a simple facility. In particular, a method for producing a blow molded article comprising the steps of supplying between forming molds a molten parison formed from a crystalline resin, clamping the molds, blowing a pressurised fluid into the parison so that the parison is tightly secured to the forming surface of the molds and allowing the parison to be solidified, wherein the temperature of the forming surfaces of the molds when the parison is tightly secured thereto ranges from a temperature lower by 10 °C than a crystallizing temperature of the crystalline resin to a melting point of the resin, and wherein a coolant whose temperature is lower than a room temperature is introduced into the parison while the pressurised fluid is being blown in or after it has been blown in for cooling the parison, thereafter the parison being ejected from the molds. An apparatus for producing a blow molded article comprising a blow molding machine, forming molds for use with the blow forming machine for producing a blow molded article and each having gas vent holes with a diameter of 100 νm or less and at a pitch of 50 νm or less, and a means for introducing a coolant into the parison formed through the molds and discharging it from the parison.
