摘要： To replenish a powder supply section (40) with a powder material, a powder-material reservoir (30) is mounted in a reservoir placement section (43) located on the upper side of the powder supply section (40). After the completion of a modeling operation on a modeling stage (62) in a modeling mechanism (60), the modeling stage (62) is lowered and a carrier mechanism (65) operates to carry a mesh tray (9) and a three-dimensional (3D) object (91) on the modeling stage (62) to a treatment chamber (72). In the treatment chamber (72), removal of unbound powder adhering to the 3D object (91) and post-processing are performed automatically. Such a configuration allows automatic fabrication of a 3D object of high binding strength without scattering the powder material therearound.

摘要： A method of forming an interior trim part having an insert and a spray formed layer. The insert has a rib that is received in a groove formed in a surface of the mold. The groove is provided with a vacuum port that may be used to draw the insert into the groove while the spray polymer layer is applied over at least a portion of the back of the insert. The bead receiving groove may be partially formed by a tool insert to which the vacuum is ported. The insert may be formed as a multi-layer film including a backing layer, decoration layer and clear coat layer. The multi-layer film may be vacuum formed to create a bead or rib on the insert. The method and tool may be used to form an interior trim part such as a floor covering with integral floor mats.

摘要： A method of making a skin of an interior trim part and an interior trim part made according to the process. A male mold having a convex portion is used to form a skin having a uniform thickness that is sprayed on the surface of the mold. The surface of the mold has a grain pattern that is transferred to a skin. The skin is allowed to flash off or partially cure before being removed from the male mold. The skin is then turned inside out with the exterior surface being inverted to form a convex portion of the skin. The skin is placed into a female mold having a concave portion against which the convex portion of the skin is placed. Foam is injected into the inverted skin while in a female mold and is cured to form an interior trim part.

摘要： A method of forming a polyurethane article wherein first and second components of a polyurethane system are sprayed into an unconfined space above a mold. The first and second components are sprayed together to mix initially in the space above the mold and then are deposited in the mold on an in-mold coating that was previously applied to the mold. The two components of the polyurethane system and in-mold coating are subsequently removed from the mold as a flexible polyurethane skin. The skin may then be placed in a second mold along with a reinforcement. Structural polyurethane foam may then be injected to the second mold where it bonds to the reinforcement and the skin to form a finished polyurethane article having a flexible skin adhered to its surface. A post-mix spray nozzle assembly is provided with a central nozzle forming a first hollow conical spray pattern and a coaxially aligned annular nozzle forming a second hollow conical spray pattern. The first and second hollow conical spray patterns intersect in space remote from the nozzle and form a hollow circular spray pattern.
摘要翻译：一种形成聚氨酯制品的方法，其中聚氨酯体系的第一和第二组分被喷射到模具上方的无侧限的空间中。将第一和第二组分喷涂在一起，最初混合在模具上方的空间中，然后在模具中沉积在预先施加到模具上的模内涂层中。随后将聚氨酯体系和模内涂层的两个组分作为柔性聚氨酯表面从模具中去除。然后可以将皮肤与增强件一起放置在第二模具中。然后可以将结构聚氨酯泡沫注入第二模具中，其中它与增强物和皮肤结合，以形成具有粘附到其表面的柔性皮肤的成品聚氨酯制品。后混合喷嘴组件设置有形成第一中空锥形喷雾图案的中心喷嘴和形成第二中空锥形喷雾图案的同轴对准的环形喷嘴。第一和第二中空锥形喷雾图案在远离喷嘴的空间中相交并形成中空圆形喷雾图案。

摘要： Disclosed is an inventive process for the manufacture of polymeric seamless belts, e.g. drive, fuser or toner belts for reprographics applications. The novel seamless belts can have a smooth outer surface the dimensions and quality of which are effectively determined by the inner surface of a hollow mandrel employed as a mold during manufacture. The mandrel inner surface can be highly polished to enhance the smoothness of the belt outer surface, and can be formed of a material with a lower coefficient of thermal expansion than the belt polymer to facilitate removal of the belt from the mandrel after curing. The molded belt can be used nullas isnull, be sliced into smaller belts or be employed as a substrate for deposition of additional belt layers and then, optionally, sliced. The polymer, e.g. a polyimide, can be deposited on the mandrel inner surface by electrostatic powder spraying employing an inventive apparatus employing a rotating mandrel and a powder spray gun reciprocable along the rotating mandrel axis. Electrostatic powder spraying is advantageous in avoiding use of volatile organic solvents and providing an environmentally friendly process.
摘要翻译：公开了用于制造聚合物无缝带的本发明方法，例如。驱动器，定影器或调色剂带进行复制应用。新颖的无缝带可以具有光滑的外表面，其尺寸和质量由在制造期间用作模具的中空心轴的内表面有效地确定。心轴内表面可以被高度抛光以提高带外表面的平滑度，并且可以由具有比带状聚合物更低的热膨胀系数的材料形成，以便于固化后从芯棒上除去带。模制带可以“按原样”使用，被切成较小的带或用作基底以沉积附加的带层，然后可选地切片。聚合物，例如聚酰亚胺可以通过使用采用旋转心轴的本发明装置和沿着旋转心轴轴向往复运动的粉末喷枪的静电粉末喷涂沉积在心轴内表面上。静电粉末喷涂有利于避免使用挥发性有机溶剂并提供环保工艺。
