Provide one-stop insulation material processing and customized molding
1, the starry wheel is a clamp application in various plane polishing steps such as glass, lens, silicon wafers, hard drives, but also known as polishing fixtures, polishing pads, etc .; polishing process has been developing for many years, which has been very mature, in recent years, mobile phones , The mass electronic products such as the tablet have a large amount of popularity, the touch screen speed is developed, and the lens polishing has a thousand miles, and the raw materials of the chartee turn becomes the FR-4 glass fiber sheet by the original blue steel sheet.
2, the main material of the current starry is FR-4 glass fiberboard, comprehensive features, glass fiberboards are the most suitable materials in the market, such as wear-resistant, easy processing, processing steps. However, the polishing workpiece, etc. It has been professional exploration here, and improved the production formula of epoxy resin sheets!
3, use materials: high quality glass fiberboard (FR-4) material properties: high temperature resistance 180-200 ° C, high mechanical properties and dielectric properties, better heat resistance and moisture resistance, smooth surface, and have Good machining. Material color is: white, yellow, black, water green. Applicable to: All kinds of products that need to be polished, the application is very extensive. Such as: mobile phone glass (mobile phone touch screen) hard disk ...
4, the manufacturing process of the tricks is very particular, the lens or silicon wafers, the polishing of gems is very fine, so the refined requirements for the starry, of course, even if they still have a lot of glasses. The factory uses a stamped method to make a starry wheel, the reason is just because the production cost of this approach is very low, and the polishing workpiece has no requirement, so it will choose stamping production; currently most of the star is now using a computer The huge advantage of, this way is that the processing accuracy of the finished product is very high, which can be controlled within 0.02mm, the cut surface is very smooth, there will be no burrs, and even see the processed traces.
