Method of manufacturing a bladder element with an etched feature and article having a bladder element with an etched feature
A method of manufacturing an article comprises etching an etched feature on a surface of a first polymeric sheet, and forming a fluid-filled bladder element from the first polymeric sheet, with the fluid-filled bladder element having a sealable internal cavity that retains fluid. The method includes assembling the bladder element in the article so that a first portion of the bladder element having the etched feature is exposed to view, and a second portion of the bladder element is blocked from view by the article. An article includes the bladder element with the etched feature.
Method for producing plastics containers
The invention relates to a method for producing plastics containers from thermoplastics with inserts which, by exploiting the heat of plasticization, are connected during shaping of the plastics container by a material bond and/or interlocking connection to the container wall, wherein the method provides the use of at least one opening on the insert, which opening forms a melt duct or melt inlet and/or melt passage for plasticized or plastic material of the container wall, wherein the method is distinguished in that the opening is monitored as a reference opening by optical and/or sensory means during the production of the connection, wherein the degree of penetration of the opening with thermoplastic from the container wall is used as a measure of the quality of the connection.
Container, folding container
The present disclosure provides a container with an increased movable range of an upper wall with respect to a side wall. According to the present disclosure provided is a container including a side wall, an upper hinge member, and an upper wall, wherein the upper hinge member and the side wall are connected rotatably around a first rotation axis, the upper hinge member and the upper wall are connected rotatably around a second rotation axis, and the first and second rotation axes are parallel.
CONTAINER HAVING COORDINATED MOLD PART LINE AND LONGITUDINAL SEAM
A container including a longitudinal overlapping seam extending from an end seam and a mold part line extending from the closed end of the container to the open end of the container. The container wall consists of a one-piece thermoplastic substrate.
PARISON SEPARATION DEVICE, BLOW MOLDING MACHINE, AND METHOD FOR MANUFACTURING BLOW-MOLDED ARTICLE
A parison separation device (30) according to an embodiment includes a cutter (31) with a cutting edge (35), the cutting edge (35) extending in a one direction and facing upward, and a block (33), the cutter being attached to an upper part of the block (33), inclined surfaces (37) being formed on both sides of the block (33) in a thickness direction of the cutting edge (35), each of the inclined surfaces (37) including a component that is inclined increasingly downward as it gets closer to one direction side end, in which the parison separation device (30) is disposed on a discharging direction side of a discharging port of a parison and configured to cut the parison discharged from the discharging port.
HEAT-INSULATING TRANSPARENT POLYVINYL CHLORIDE SHEET HAVING EXCELLENT WEATHERABILITY AND PROCESS FOR PRODUCING THE SAME
A heat-insulating transparent PVC sheet is formed from a PVC substrate having a thickness of 0.02-2.0 mm and contains heat-insulation pastes evenly distributed over the PVC substrate, since the heat-insulation paste contains an essential component of wolfram cesium powder (WCs) with a chemical formula of Cs.sub.XN.sub.YWO.sub.3-ZCl.sub.C and having a particle size of 0.005-2 m, the heat-insulating transparent PVC sheet has an excellent weatherability, and particularly before and after tested in 300-hour service life in line with ASTM G-154 specification, has a physical property of weatherability decay rate (%) small than 4%.
BLOW-MOLDED FOAM
An object of the invention is to provide a blow-molded foam which has homogeneous foamed cells in size, is light in weight, and is excellent in surface smoothness, and a process for producing the same. The invention is directed to a blow-molded foam 1 having a wall portion formed in such a manner that a thermoplastic resin containing a foaming agent mixed therewith is subjected to blow molding. Herein, the wall portion has a closed cell structure in which a plurality of foamed cells are contained. The wall portion has an expansion ratio of not less than 2.0 times. The wall portion has an outer face having a center-line average surface roughness Ra of less than 9.0 m. The foamed cell has a cell diameter having a standard deviation of less than 40 m in a thickness direction of the wall portion.
Components molded with moldable carbon fiber and methods of manufacturing thereof
In various aspects, the present disclosure provides a structural component. The structural component includes a body defining at least one hollow region. The body includes a carbon fiber composite including a plurality of substantially aligned continuous carbon fibers. The plurality of substantially aligned carbon fibers defines a major axis and a second axis perpendicular to the major axis. The plurality of substantially aligned continuous carbon fibers includes a plurality of discrete termination points staggered with respect to the second axis. Methods of making such structural components, including by blow molding and compression molding are also provided.
PROCESS FOR PRODUCING HOLLOW RESIN-MOLDED ARTICLE, AND FUEL TANK
A process of producing a hollow resin-molded article includes: arranging covers on inner walls of mold halves, the covers having shapes corresponding to the inner walls; introducing a pair of sheets of thermoplastic resin each facing the cover arranged on the inner wall of a corresponding mold half; blowing air into a space between the sheets to cause the sheets to respectively contact the covers arranged on the inner walls, and thereby fusion-welding the sheets to the covers; and closing the mold halves; and cooling down the covers and the sheets in a state where the mold halves are closed. In the step of arranging, there are uncovered portions of the inner walls that are not covered by the cover. In the step of closing, there are mold contact portions of the sheets that respectively contact the uncovered portions directly and the mold contact portions are fusion-welded to each other in an overlapping manner.
