A panel including a surface made of a synthetic material may be subjected to a material removal process to create a specific decorative or architectural appearance. In one embodiment, a panel of cellular PVC is blasted with an abrasive material such as crushed glass to create a realistic stucco appearance on the panel surface. Benefits related to using certain synthetic materials as cladding may be realized, such as weather resistance. A coating containing aggregate may be applied to the blasted panel to enhance the surface appearance.

A method for surface treating a golf club head, includes: (a) forming a depression unit in the golf club head, the depression unit being indented inwardly from an outer surface of the golf club head, the outer surface being divided into a working area and a non-working area, the depression unit being formed in the working area; (b) filling the depression unit with a shielding material and covering the non-working area with a covering material; and (c) sandblasting the golf club head after step (b) and removing subsequently the shielding material from the depression unit and the covering material from the non-working area so as to form the working area into sandblasted and non-sandblasted regions that differ in gloss intensity.

A method of increasing a roughness of coiled tubing injector blocks that includes providing a pair of gripper blocks each having a gripper surface configured to grip coiled tubing within an injector head and increasing a first roughness on the gripping surfaces to a second roughness. A coating may be applied to the gripping surfaces to increase the roughness. The coating may be chromium carbide, molybdenum boride, iron boride, titanium boride, or a transitional metal boride. The gripping surfaces may be treated to increase the roughness to a second roughness. The gripping surfaces may be blasted by abrasives or shot peened to increase the roughness. The second roughness may be greater than 20 μm. A system to inject coiled tubing into a wellbore may include an injector head, coiled tubing, and at least two gripper blocks having a gripping surface with a roughness of at least 20 μm.

A manufacturing process of a heat-resisting glass or enamel coating of a thermally insulated container chamber is described. The process comprises selecting a thermally insulated metal container body, and performing sand blasting to a chamber surface of the body such that the chamber surface becomes a rough surface. The process comprises spraying a glass or enamel glazing material on the rough surface of the body and drying the glazing material on the rough surface. The process comprises placing a dried body on a bracket and sintering the dried body. After sintering is performed, the process comprises removing the body from the bracket. Using this disclosure the chemical properties of the glass coating or enamel coating are relatively stable, so corrosion will not occur. Because the thermal expansion and cold contraction are relatively small, the coating is suitable for manufacturing thermally insulated containers such as thermally insulated cups.

The invention relates to a method comprising the steps of: Abrasion, preferably but non-limited by means of sandblasting which produces mechanical roughing on the surface of the glass substrate, optionally applying a primer on the roughed surface, and applying an ink on this primer by means of screen printing which may be digital inkjet screen printing, drying the injected ink deposited by means of digital screen printing, and performing a tempering process. A glass substrate with an embossed surface finish is achieved which simulates the aesthetic and surface texture of different construction materials, such as stone, wood, granite, marble or porcelain, among others.

Textured cover assemblies for electronic devices are disclosed. The textured cover assemblies may provide a combination of optical and tactile properties to the electronic devices. In some cases, a textured cover assembly may be provided over decorative coating.
