Abstract: A cable jacket extruder comprises a chamber, a feeding port disposed at one end of the chamber, an extruding screw disposed inside the chamber, a pathway connected to an outlet at another end of the chamber, wherein a vent is defined on the pathway, and a nozzle connected to the pathway. In another example, a tandem-type cable jacket extruder is provided. The tandem-type cable jacket extruder comprises a first chamber and a second chamber connected in tandem via a pathway, a vent disposed on the pathway, a feeding port disposed at one end of the first chamber, and an extruding screw disposed in each of the first and second chambers. A method for manufacturing cable jackets is also provided.

Abstract: Polishing tools and methods of polishing a glass substrate are disclosed. A polishing tool (200) includes a stem (220) and a polishing material (210) bonded to the stem (220). The polishing material (210) includes, in volume concentration, about 18% to about 42% phenolic resin, about 18% to about 30% zinc oxide, about 1% to about 10% magnesium oxide, a cooling agent, and an abrasive.

Abstract: A method of edge coating includes preparing a stack including a plurality of articles interleaved with spacer pads. A layer of coating material is formed on a surface of a coating roller. A perimeter of the stack is positioned at a select coating gap relative to the surface of the coating roller, and the coating material is transferred from the surface of the coating roller to perimeter edges of the articles in the stack.

Abstract: A method of applying a protective coating to a substrate includes applying a surface treatment to edges of the substrate to increase surface wettability of the edges and/or preheating the substrate. A curable coating material is applied to the edges. Then, the substrate is spun to adjust a thickness and uniformity of the curable coating material applied on the substrate edges. The curable coating material is cured to form the protective coating on the substrate edges.

Abstract: A manufacturing method of carbonaceous heat sink includes a mixing step and a molding step. In the mixing step, a graphite material is mixed with a thermosetting binder to obtain a mixture. In the molding step, the mixture is pressure formed with a mold into the carbonaceous heat sink, Preferably, the carbonaceous heat sink can increase its carbonaceous percentage by using a heat treating step. The manufacturing method can produce carbonaceous heat sinks with a high carbonaceous percentage with a low cost.
