Plastic Balls Manufacturer shares how plastic surfaces are polished?
1. Electrolytic polishing: basically the same as chemical polishing, that is, by selectively dissolving tiny protrusions on the surface of the material to make the surface smooth. Compared with chemical polishing, the effect of cathode reaction can be eliminated, and the effect is better. The electrochemical polishing process is divided into two steps: the macro-leveling dissolved product diffuses into the electrolyte, the geometric roughness of the material surface decreases, Ra> 1μm; the low-light leveling anode polarization, the surface brightness increases, Ra <1μm.
2. Ultrasonic polishing: Put the workpiece into the abrasive suspension and put it in the ultrasonic field together, relying on the vibration of the ultrasonic wave to make the abrasive grinding and polishing on the surface of the workpiece. Ultrasonic processing has a small macro force and will not cause deformation of the workpiece, but tooling is difficult to manufacture and install. Ultrasonic processing can be combined with chemical or electrochemical methods. On the basis of solution corrosion and electrolysis, ultrasonic vibration is added to stir the solution to dissolve the dissolved products on the surface of the workpiece, and the corrosion or electrolyte near the surface is uniform; the cavitation effect of ultrasonic waves in the liquid can also inhibit the corrosion process, which is beneficial to the surface brightening.
