摘要： A three-dimensional electroformed shell for a mold consists of a three-dimensional thin-walled body, and an electroformed coating deposited on it. The coating may, or may not close the base holes of the thin-walled body completely. If it does not close the base holes completely, the shell has a multiplicity of apertures. A process for manufacturing the shell is also disclosed.

摘要： The process of the present invention involves molding a 3-D molded product from a sheet. The molded product includes a product section, which turns out to be a product, and an extra product section, which is to be excised. The sheet is made of a thermoplastic polymeric material. The process includes clamping the sheet at its peripheral edge; heating and softening the sheet; deforming the heated and softened sheet by stretching the sheet along a 3-D molding surface of a mold; and adhering the sheet to the 3-D molding surface to mold the 3-D molded product. A thickness of the product section is made up by moving the sheet material at the extra product section to the product section during the deforming step by partially releasing a tensile stress of the extra product section.
摘要翻译：本发明的方法包括从片材中模制3-D模塑产品。模制产品包括产品部分，其被证明是产品，以及要被切除的额外产品部分。片材由热塑性聚合材料制成。该方法包括将片材夹在其周边边缘; 加热和软化片材; 通过沿着模具的3-D成型表面拉伸片材来使加热的软化片材变形; 并将该片粘合到3-D成形表面上以模制3-D模制产品。通过部分地释放额外产品部分的拉伸应力，通过在变形步骤期间将片材在额外产品部分移动到产品部分来制成产品部分的厚度。

摘要： A poreless first layer is electroformed on the conductive surface of a mandrel in an electroforming solution containing a substantial amount of a surface active agent. After the mandrel and the first layer are lifted from the solution, small straight pores each having an approximately equal diameter along a length thereof are formed through the first layer defining the front side of a porous electroformed shell. A second layer is deposited on the back side of the first layer in an electroforming solution containing less than the substantial amount of a surface active agent to form the back side of the shell, while undeposited hollow portions are formed in alignment with the straight pores in the first layer in initial formation of the second layer, the hollow portions enlarging to form diametrically enlarged pores through the second layer, the enlarged pores having a diameter which becomes larger toward a surface of the second layer opposite from the first layer.
