Beim Extrusionsblasen von HDPE mit aggressivem Blasmedium wird das Entweichen von Blasmedium an der Berührungsfläche Blasdorn/HDPE verhindert, wenn man einen Blasdorn (1, 2) mit einem axial beweglichen Dichtelement (3) verwendet.
摘要:
Filamented, hollow microspheres are disclosed which are connected or attached by a thin continuous filament. The filaments reduce contact between microsphere and reduce thermal conductivity therebetween and assist in handling and preventing scattering of microspheres. Preferably, the connecting filaments are 7 to 20 times the diameter of the microspheres. The microspheres are preferably free of holes thinned wall portions or sections and bubbles. The filamented microspheres can be used to make insulation materials, composites and insulating systems.
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.
摘要:
The invention concerns a method of delivering a predetermined volume of a liquid product into a thermoplastic container formed from a heated preform (3) positioned in a mold (2) having an opening opposite an injection head (6a), characterized in that, prior to injecting the liquid product in the preform (3) causing expansion of the container, the method includes a step of, at least partially, filling the preform (3) with an inert component in relation to the liquid to be injected.
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.

Methods for fabricating stents 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 (335) along the axis, the polymer tube having an internal tube pressure higher than ambient; controlling the deformation to provide a selected fracture of a stent fabricated from the tube; and fabricating the stent from the deformed tube.
摘要:
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:
This invention relates to the post-formation processing of extruded or injection molded profiles in an economic manner without the need to purchase a blow molding machine, yet still effect post-formation radial expansion or contraction by the application of sufficient degree of heat or the performing of the operation sufficiently quickly to permit the utilization of the retained latent heat from the extrusion or injection molding process.
