A machine for working a workpiece made of wood, plastic, glass, fiberglass, metal, ceramic, and the like including an entry station for the entrance of the workpiece to be worked and an exit station for the exit of the worked workpiece; a conveyor group for moving the workpiece to be worked, according to a forward direction, from the entry station towards the exit station; at least one working unit of the workpiece, arranged overhead with respect to the conveyor group including at least one working tool of the workpiece; the machine including a laser system configured for carrying out further working operations on the workpiece. Also disclosed is a laser system that can be installed on a machine for machining a workpiece and an operation method of a machine for machining a workpiece.

Disclosed are methods and coatings for protecting the surface of a non-metallic composite part, comprising applying a protective layer to an exposed surface of the non-metallic composite part, the protective layer comprising: (a) a multilayer having at least a co-cured layer applied to the surface of the non-metallic part and laser-sensitive layer applied to a surface of the co-cured layer, wherein the laser-sensitive layer is selected from a reflective layer, an optical sensor layer or a layer having both reflective and optical sensor properties; or (b) a co-cured coating which comprises a laser-sensitive material incorporated therein to form a laser-sensitive co-cured layer applied to a surface of the non-metallic composite part, wherein the laser-sensitive material is selected from a reflective material, an optical sensor material or a combination thereof, such that the non-metallic composite part will be protected from damage during subsequent laser ablation to remove an outer coating.

In this method for manufacturing a vehicle part, the following steps are implemented, applying a first varnish coat to a transparent part, applying a paint coat to the first varnish coat, applying a second varnish coat to the paint coat, and irradiating the paint coat and the second varnish coat in part with laser radiation.

A decorative member according the present disclosure includes: a wooden veneer having a plurality of through-holes which transmit light from a back face side to a front face side; a transparent reinforcing layer laminated to a back face side of the veneer; and a coating layer which is laminated to a front face side of the veneer and fills interiors of the plurality of through-holes.

Embodiments enhance graphic capabilities in projected-capacitive (PCAP) touch sensitive systems, and more specifically to a border component of a PCAP touchscreen. Embodiments include a method and an apparatus for a PCAP touchscreen layered structure. Some embodiments include screen printing a border component on a cover sheet, curing the border component, ablating a pattern on the border component, and screen printing one colored ink onto the pattern on the border component. In some embodiments the border layer is black, and the colored ink is coupled to a cover sheet. The pattern causes the colored ink to appear as a continuous gradient of the colored ink. In some embodiments the border component includes two or more border-layer components. At least one of the border-layer components may include an ablated pattern. Each ablated pattern may be coupled to a different colored ink.

A system and method of creating a decorative component having multiple surface finishes includes providing a substrate with a metal surface layer and treating the metal surface layer to remove oxidation, and applying a coating or paint layer over at least a portion of the treated metal surface layer. The paint layer is removed via laser ablation to define a metal-paint interface. The metal-paint interface created by laser ablation applied to paint over treated metal is free from adhesion failure. The workpiece created includes multiple surfaces having complex shapes and features, and may be applied to a variety of surfaces. Multiple surface finishes are therefore created on a single part without the need for assembly of separate parts, with a robust interface between contrasting surface appearances.

The automobile decorative-part (1) comprises a resin-compact (3) having a decorative-layer (2) on its surface-layer and comprises a clear-coat layer (4) for protecting said surface-layer, and that a high-gloss region (R1) of a relatively high-gloss level is mixed with a low-gloss region (R2) of a relatively low-gloss level on the surface of said decorative-part, and that a clear-coat paint is sprayed by an atomization-coating machine onto the surface of the decorative-layer (2), and that the atomization-coating machine contains an ester-based solvent of a low-boiling point as the main-solvent that has a boiling-point of 100 degrees Celsius or less and has a solid-content of 35 to 40 percent by mass, thus forming the clear-coat layer (4) that makes it partially possible to mat the gloss of the surface of the clear-coat layer, thus manufacturing a decorative-part with an excellent quality design.

A method for laser carving of paint on an outer surface of a vehicle wheel includes a step of priming: priming an outer surface of the wheel to form a painted surface; a step of laser carving: carving the primer from a selected area of the wheel by laser to remove the painted surface from the selected area, the selected area having an exposed area with metallic luster, and a step of fine-polish: polishing the outer surface of the wheel to form a fine-polished area at the exposed area. The painted surface on the wheel can be quickly removed to disclose a selected area with metallic luster, while the wheel is prevented from corrosion so as to reduce manufacturing cost and increase precision.
