This kneading rotor (1) is rotatably disposed about a horizontally oriented shaft center, the kneading rotor including at least two or more of kneading flights (7) that are disposed about the shaft center and knead a material. In a cross-section perpendicular to the shaft center of the kneading rotor (1), the kneading flights (7) are provided with working faces (9) that face the material when the kneading rotor (1) is rotated. Recesses (10) where a part of the working faces (9) are partially recessed radially inward are formed on the working faces (9) of the kneading flights (7).

A molding apparatus includes an extruder to provide a molten composite material, and an adjustable extension barrel coupled to the extruder to receive the molten composite material. The adjustable extension barrel has a drop point to output the molten composite material. The adjustable extension barrel is moveable in a first direction between an extended position and a retracted position to change position of the drop point. A structure is movable in a second direction that is perpendicular to the first direction. A lower mold is carried by the structure and is positioned to receive the molten composite material from the drop point of the adjustable extension barrel. A press includes an upper mold and is operated to press the upper mold against the lower mold to form a molded article.

A filtering device (100′) for the large-area filtration of polymer melts comprises at least: a housing (20; 20′) with at least one inlet channel (23; 71′) and at least one outlet channel (26; 61′) and a filter carrier element (40, 40′), which can be moved longitudinally in relation to a housing bore and has at least one filter insert (10; 10′), which in a production position can be arranged in a filter chamber (24; 24′) between the inlet channel (23; 71′) and the outlet channel (26; 61′) of the housing (20; 20′), wherein the filter insert (10, 10′) has a main element (12, 12′) through which the flow can pass, and from which a fluid stream branches off to multiple individual filter elements (11, 11′) or in which multiple fluid streams from the individual filter elements are combined. The filter insert (10, 10′) is arranged on an end face of the filter carrier element (40, 40′). The filter chamber (24, 24) is formed by a housing bore, which extends up to a mouth (25) on an outer side of the housing and into which the filter insert (10, 10′) can be pushed by moving the filter carrier element (40, 40′), and a closure element (41, 41′), which can be placed onto the mouth (25) of the housing bore and/or can be inserted therein when the filter carrier element (40, 40′) is lowered into the housing bore or thereafter.
摘要:
Provided are a resin tube for a guide wire, a method for manufacturing a resin tube for a guide wire, and a guide wire, configured such that the resin tube makes point contact in the axial direction with an object of contact at working site, thereby reducing frictional resistance and yielding excellent sliding properties, while also being prevented from kinking and collapsing, and having excellent buckling resistance. The resin tube for a guide wire is characterized in that the outer shape of a cross-section perpendicular to the axial direction is polygonal, elliptic, or irregular, that the resin tube is twisted in a helical shape about a deep inner-core hole as the axis of twisting, the deep inner-core hole extending in the axial direction and allowing a core wire to be inserted therein, and that the resin tube is provided with a trunk section having an undulation on the outer surface caused by the twisted eccentric wall thickness.

The molded article includes a resin composition with a single shaft extruder, in which the resin composition is generated by melting and mixing a raw mixture, the raw mixture being obtained by blending 40-90 parts by mass of the polyolefin (A), 3-30 parts by mass of the metaxylylene group-containing polyamide (B), and 3-50 parts by mass of the modified polyolefin (C). In the single shaft extruder, the ratio of the length of the feeding part to the screw effective length is 0.40-0.55, the ratio of the length of the compressing part to the screw effective length is 0.10-0.30, the ratio of the length of the measuring part to the screw effective length is 0.10-0.40, the upper limit of the temperature of the feeding part falls within the range of +20° C. from the melting point of the metaxylylene group-containing polyamide or less, and the temperatures of the compressing part and the measuring part fall within the range of −30° C. to +20° C. from the melting point of the metaxylylene group-containing polyamide, and the shear rate is 14/second or more.
摘要:
Extrusion and compression molding methods for making X-ray detectable, resin-based material in stock shapes such as rods and sheets. The rods and sheets include barium sulfate in a concentration such that the structural properties of the resin are not materially altered from those of pure resin, but relatively small fragments of the material are X-ray detectable by conventional equipment, even at high line speeds.

Adding a small amount [trace] of finely ground polyethylene to pvdc prior to extrusion, protects the pvdc from decomposing to hydrogen and carbon. This enables longer extruder run times, lower waste, and a higher quality product.
摘要:
The purpose of the present invention is to provide a screen unit which allows for eliminating rigorous dimension control for preventing the short path phenomenon of material and which has cost advantages, and a screen changer equipped with the same.In the screen unit, a cartridge body (30) includes a hole-formed portion (15) having a plurality of through holes (12) through which the material filtered by a screen pack (14) is allowed to pass; and a contacted outer surface (21) which is provided closer to a base end side than to the hole-formed portion (15) and inclined so as to expand radially outwardly with decreasing distance to the base end. The screen pack (14) has a contacting inner surface (22) which can closely contact with the contacted outer surface (21) of a cartridge (13) when being pressed from a tip end side toward the base end with the hole-formed portion (15) covered from outside.
