This invention is directed to a process for applying a symbol to a molded device which symbol on the molded device is visible as an indentation in the surface of the device. The process involves the step of applying the symbol as an elevation to the mold before using the mold for making the molded device. The process of the invention is characterized in that the elevation on the mold is produced by applying a material to the mold surface which material is liquid when being applied and which material is applied at a temperature higher than the temperature which is at or preferably below the melting point of the material, and which material solidifies at the temperature of the mold. The material applied to the mold and solidified on the mold surface as an elevation needs to remain solid during the process of using the mold for making the molded device. During the molding process the elevation of the symbol on the mold is transferred as an indentation of the symbol to the surface of the molded device. After the molding process is complete and the molded device has been separated from the mold the elevation on the mold surface can be removed and the mold can be re-used without an elevation or with another elevation being applied to make another molded device.

A vehicle interior panel such as an instrument panel includes a substrate having a thickness between 0.5 mm and 2.25 mm, inclusive, a decorative layer, and an intermediate layer located between the substrate and the decorative layer. A post-form warpage of the substrate is less than 15 mm at an edge region of the substrate. A serpentine rib located near the edge region helps impart structural rigidity to the panel during a foaming process to achieve an adequate degree of post-form warpage.

The nanoimprint mold (100) includes a base substrate (10). The base substrate (10) includes a main area (MA) and a secondary area (SA) surrounding the main area (MA). The main area (MA) includes a molding structure (16), and the molding structure (16) includes a plurality of first concave portions (18) and a plurality of first convex portions (20). The secondary area (SA) includes a grating structure (22), and the grating structure (22) includes a plurality of second concave portions (24) and a plurality of second convex portions (26). A height of at least one of the second convex portions (26) is larger than a height of at least one of the first convex portions (20). The nanoimprint mold (100), manufacturing method thereof, and pattern transfer method using nanoimprint mold (100) make the overflow of the nanoimprint resist in the secondary area (SA) of the nanoimprint mold (100) is significantly suppressed, and the topography of pattern in the secondary area (SA) of the nanoimprint mold (100) is significantly improved. Furthermore, the thickness of the resist layer in the adjacent areas will not be significantly increased. Accordingly, the defective area of the pattern of the resist layer, especially at the joint area between the two nanoimprinting positions, is significantly reduced.

Thermoplastic forming tools and assemblages are provided for forming thermoplastic components. In particular, thermoplastic forming tools and assemblages are provided for forming thermoplastic components having precision micro-scale features and reproducible macro-scale dimensions. The thermoplastic forming assemblages can include at least a bottom tool and a top tool having a rigid tool body and an elastomer layer conformally coating at least a portion of both rigid tool bodies. The bottom and top tool can be so dimensioned that, when in the closed position, they define a cavity forming the thermoplastic component. The rigid tool bodies provide the reproducible macro-scale dimensions in the thermoplastic component, while the elastomer layers form and release the precision micro-scale features in the thermoplastic component when formed. Tool-forming structures are also provided for making thermoplastic forming tools and assemblages, as well as methods of making the thermoplastic forming tools, and methods of use for forming thermoplastic components.

The present disclosure relates to an aerosol production assembly. The aerosol production assembly may include a reservoir that contains an aerosol precursor composition and an atomizer that receives the aerosol precursor composition from the reservoir and heats the aerosol precursor composition to produce an aerosol. The aerosol production assembly may additionally include a body that directs the aerosol through an outlet. The body may include a surface including a micro-pattern that defines at least one of hydrophobic and anti-microbial properties. The surface including the micro-pattern may not include a chemical coating that provides these properties. Rather, the surface may define a three-dimensional structure that provides hydrophobic and/or anti-microbial properties. A related assembly method is also provided.
