Methods of applying a polymeric coating to a rear face surface of golf club heads with variable face thickness are disclosed herein. The coating, which preferably comprises polyurea, improves the durability of the face and reduces the hits to failure ratio of the golf club head. The coating improves the performance of the golf club head because it allows for reduction in overall face thickness and easy post-process manipulation to allow for fine-tuning of mass properties after production. The reduction in thickness leads to overall weight reduction, because the polymer is roughly a quarter of the density of titanium or stainless steel, and also reinforces the face, thereby increasing the lifespan of the club.

Methods of selectively depositing films on substrates are described. A passivation film is deposited on a metal surface before deposition of a dielectric material. Also described is exposing a substrate surface comprising a metal surface and a dielectric surface to a docking precursor to form a passivation film.

Provided herein are methods and systems for the custom-printing of an item including, e.g., a) accepting customer request data for a workpiece and customer request data for a graphic design to cover at least a portion of the workpiece; b) accepting workpiece identifier data from a workpiece database based on the customer request data; c) accepting print design data from a print design database based on the customer request data for a graphic design; d) associating the print design data with the workpiece identifier data; e) printing the print design data onto a hydrofilm portion; f) placing the hydrofilm portion onto a fluid surface in a dip tank; g) applying an activator to the hydrofilm portion to yield an activated hydrofilm portion; and h) dipping the workpiece into the dip tank, whereby the activated hydrofilm portion is bonded to the workpiece as a result of the dipping.

A deposition mask in which deformation of long sides is restrained is manufactured. A manufacturing method of a deposition mask includes a step of preparing a metal plate; a processing step of processing the metal plate into an intermediate product comprising: a plurality of deposition mask portions each including a pair of long sides and a pair of short sides, and having a plurality of through-holes formed therein; and a support portion that surrounds the plurality of deposition mask portions, and is partially connected to the short sides of the plurality of deposition mask portions; and a separation step of separating the deposition mask portions from the support portion to obtain the deposition mask. In the intermediate product, the long sides of the deposition mask portions are not connected to the support portion.

A method for decorating the surface of a mechanical part including structuring, on the surface to be decorated, a masking layer having a thickness that is at least equal to the thickness of the decoration element to be produced; making, in the masking layer, at least one opening that coincides with the location on the surface to be decorated where the decoration element is to be produced, the opening having a contour that is identical to the contour of the decoration element and defining a volume with the mechanical part; filling the volume delimited by the masking layer and the surface to be decorated of with a filling material wherein the decoration elements are sought to be produced; and removing the masking layer.

The invention relates to an apparatus for the vapor deposition of a coating on optical articles, comprising a distribution mask (32) for controlling the vapor deposition of a coating on optical articles that is positioned in the path of some of the molecules emitted by said emitting source in the direction of the rotatable support for optical articles. The distribution mask (32) is fitted with at least one arm (34) positioned so as to mask at least one partial zone (16) of an individual housing (28) on a portion of the revolution turn, this masked partial zone (16) comprising the center of the individual housing (28).

The disclosed device is an adapter to an existing caulking methodology. The adapter is configured to perform the activity of protective taping, scraping and cleaning of excess compound to occur simultaneously with caulking. The disclosed adapter removably attaches to cannister holding cradle of a calking gun. At least one front roller presses a strip of tape against a side of an area being caulked or finished, with tape being drawn from a tape roller in back of the front roller.

A method of coating a flexible substrate in a roll-to-roll deposition system is described. The method includes unwinding the flexible substrate from an unwinding roll, the flexible substrate having a first coating on a first main side thereof; measuring a lateral positioning of the first coating while guiding the flexible substrate to a coating drum; adjusting a lateral position of the flexible substrate on the coating drum depending on the measured lateral positioning of the first coating; and depositing a second coating on the flexible substrate, particularly on a second main side of the flexible substrate opposite the first main side. Further described is a vacuum deposition apparatus for conducting the methods described herein.

A method for creating a carbon nanotube heater assembly includes creating a carbon nanotube heater with varying resistances and attaching the carbon nanotube heater to both carrier and encapsulating materials. Creating the carbon nanotube heater with varying resistances is accomplished by applying a carbon nanotube mixture to a substrate, adjusting the thickness or width of the carbon nanotube mixture, and drying the nanotube mixture.
