摘要： The inventive method serves for producing open containers from a flat sheeting (4) consisting of a foam material or containing at least one layer of such a material, by drawing the sheeting with the help of a female (2) and a male tool (1) and by expanding the foam material with the help of a pressure reduction. The action sequence of one cycle of the inventive method is e.g. the following: positioning and clamping the sheeting (4) over the opening of the recess in the female tool (2); moving the male tool (1) into the recess and at the same time prestretching the sheeting with the help of a pressure difference between its two sides, such that the face of the male tool (1) gets in contact with the prestretched sheeting inside the recess; drawing the sheeting further by moving the male tool (1) to its end position in the recess of the female tool (2) and at the same time reducing the pressure on the female tool side or on both sides of the sheeting such that it reaches a value below ambient pressure which is sufficiently low for expanding the foam material and keeping the reduced pressure until the sheeting is cooled below plastication temperature; then equalizing the pressure and demolding and declamping the formed container and advancing the sheeting for a further method cycle.
摘要翻译：本发明的方法用于通过借助于女性（2）和男性工具（1）来拉伸片材，从由泡沫材料构成的或包含至少一层这种材料的扁平片材（4）制备开放容器）并通过在减压的帮助下膨胀泡沫材料。本发明方法的一个循环的动作顺序是例如。以下：将片材（4）定位并夹紧在阴工具（2）中的凹部的开口上方; 将阳工具（1）移动到凹槽中，同时借助其两侧之间的压力差来预拉伸片材，使得阳工具（1）的表面与内部的预拉伸片材接触休息通过将阴工具（1）移动到阴工具（2）的凹部中的终端位置，进一步拉伸片材，并且同时减小母模工具侧或片材两侧的压力，使得其到达低于环境压力的值，其足够低以膨胀泡沫材料并保持减压直到片材被冷却到塑化温度以下; 然后均衡压力并脱模并使形成的容器变形并推进该片材以进一步的方法循环。

摘要： A sun visor has a generally board shaped body of dark colored polypropylene particle foam with a depression in a main surface thereof. A shaped light colored body is inserted into the depression and is pressed against the bottom of the depression through simultaneous application of heat and pressure, for compacting and reshaping the shaped body to form a reflector. A mirror assembly is disposed over the reflector, and an illuminating device may be disposed there. Fastening pins and openings on the reflector in the mirror assembly and the illuminating device hold them together.

摘要： The heat insulator of this invention comprises a thermoformed open cell rigid polyurethane foam core enclosed in a gas barrier material and evacuated. The method of this invention comprises heating an open cell rigid polyurethane foam at a temperature not lower than the temperature at which its storage modulus of elasticity begins to decrease and enclosing the thus-thermoformed polyurethane foam in a gas barrier material and evacuating the interior of the enclosure. The heat insulator of the invention is highly heat-insulating and can be snugly applied to irregular surfaces.

摘要： A polystyrene foam sheet comprising a polystyrene resin which contains 1 to 15 wt % of a rubber component having a majority of particle sizes less than about 0.45 microns has been found to be superior for forming deep drawn articles. Optionally one or two films may be extrusion coated or laminated to the foam sheet prior to thermoforming. Also disclosed is a method for thermoforming the foam sheet. Preheat the sheet, clamp the sheet between the matched male and female mold members, move the members into final position while applying a vacuum through both members to both sides of the foamed sheet and then chill formed foam to set a final shape.

摘要： A method of making high efficiency, flame resistant polyimide foam insulation particularly suitable for insulating plastic pipes and forming ducts. Typically a sheet of polyimide foam which has been foamed unconstrained is placed between opposed caul plates, squeezed to a thickness less than the original thickness and heated to stabilize the new sheet thickness. Face sheets coated with a polyimide adhesive can then be placed against the stabilized foam faces and heated between plates to bond the face sheets to the foam. Also, a sheet of foam which had been impregnated with polyimide resin precursor can be placed against the stabilized sheet and the resin precursor simultaneously cured and the sheet bonded to the stabilized foam. A variety of flat, tubular or other shapes can be made by this method. The resulting insulation panels, tubes or the like have greatly improved flame resistance and excellent thermal insulation characteristics.

摘要： An open cell foam structure that has a negative Poisson's ratio. Structure can be created by triaxially compressing a conventional open-cell foam material and heating the compressed structure beyond the softening point to produce a permanent deformation in the structure of the material. The structure thus produced has cells whose ribs protrude into the cell resulting in unique properties for materials of this type.
