A method for forming a solar panel can include attaching one or more tacking pads to one or both of a first surface of a first solar panel subassembly and a second surface of a second solar panel subassembly. The method further includes dispensing an adhesive onto at least one of the first and second surfaces. The first and second surfaces are placed in contact with the one or more tacking pads, thereby tacking the first and second solar panel subassemblies together, during which the first and second surfaces contact the adhesive, thereby decreasing a thickness and increasing a surface area of the adhesive. Subsequently, the adhesive is cured. The tacking pad(s) maintain fixed alignment of the solar panel subassemblies during curing of the adhesive, and establish a bond line of the adhesive.

Methods of manufacturing and fixtures for manufacturing containers, particularly for holding cosmetic products, using thin-walled tubes. One end of a container may be formed using an integral process, such as insert molding, while the other end of the container is formed using assembly steps, such as welding, to form a completed cosmetics container from a thin-walled tube.

A method of constructing an inflatable fluidic actuator that includes generating a tube configuration with one or more shapes of fluid-impermeable membrane material, the tube configuration having a first tube end and a second tube end and an internal tube face and an external tube face. The method also includes coupling a first and second interface to the tube configuration at the first and second tube ends by respectively coupling each interface to the tube configuration at a respective tube end by generating at least one of: a first circumferential bond between the fluid-impermeable membrane material and one or more sidewalls of the interface; and an external face bond between fluid-impermeable membrane material at the tube end onto an external face of the interface.

The invention relates to a process for the production of at least two-layer thermoplastic sheets via thermal welding of at least one thinner thermoplastic sheet with density (D1) and of at least one second thinner thermoplastic sheet with density (D2), where the density (D1) of the first thinner thermoplastic sheet is smaller than the density (D2) of the second thinner thermoplastic sheet. The process introduces at least one first heating element and at least one second heating element along mutually offset planes between the two thinner thermoplastic sheets, where the surfaces of the thinner thermoplastic sheets do not touch the surfaces of the heating elements. The first heating element transfers a quantity of energy (E1) to the surface of the first thinner thermoplastic sheet, and the second heating element transfers a quantity of energy (E2) to the surface of the second thinner thermoplastic sheet, where the quantity of energy (E1) is smaller than the quantity of energy (E2).
