Each product does not want the surface of the product uneven, pitted face, so the surface finish of the woven mark wristband is certainly important, woven mark wristband main die polishing method is mainly to reduce the roughness of the surface of the mold steel, want to really ensure the surface finish of the woven mark wristband or need to start from the top of the mold process, so for the surface finish of the woven mark wristband mold process what are the ways to deal with it?
Woven label wristband surface is not smooth solution
Mold polishing can be divided into a variety of process ways, in the woven mark wristband mold using different processing methods, including the following surface treatment methods for the common process!
1, electrolytic polishing
Electrolytic polishing is to rely on the selective dissolution of the material surface tiny projection part, so that the surface is smooth. Compared with chemical polishing, can eliminate the impact of cathodic reaction, the effect is better. Electrochemical polishing process is divided into two steps.
(1) Macro-leveling dissolution products diffuse into the electrolyte, and the geometric roughness of the material surface decreases with Ra>1μm.
(2) micro-light leveling anodic polarization, surface brightness increased, Ra<1μm.
Mechanical polishing is by cutting the material surface plastic deformation to remove the convex part of the polished and smooth surface polishing method, the general use of oil stone, wool wheel, sandpaper, etc., mainly by hand, special parts such as the surface of the rotary body, can use the rotary table and other auxiliary tools, the surface quality requirements can be used to ultra-precise polishing method. Ultra-precision polishing is the use of special abrasives, containing abrasive polishing fluid, pressed on the surface of the workpiece being processed, for high-speed rotary motion. The use of this technology can achieve Ra0.008μm surface roughness, is higher in various polishing methods.
3, ultrasonic polishing
Ultrasonic polishing is the use of ultrasound as a driving force to promote the fine abrasive grains to very high speed impact on the surface of the workpiece, forcing the abrasive to be processed on the surface, thereby reducing its surface roughness of polishing methods.
4, fluid polishing
Fluid polishing is to rely on the high-speed flow of liquid and the abrasive particles carried by the workpiece surface to achieve the purpose of polishing. Commonly used methods are: abrasive jet processing, liquid jet processing, fluid power grinding. Fluid power polishing is driven by hydraulic pressure, so that the liquid medium carrying abrasive particles flowing over the surface of the workpiece at high speed reciprocally. The medium is mainly used in the lower pressure flow through the good special compound and mixed with abrasives made, abrasive can be used silicon carbide powder.
5, magnetic grinding and polishing
Magnetic grinding and polishing is the use of magnetic abrasives in the magnetic field under the action of the formation of abrasive brushes, the workpiece grinding process. This method has high processing efficiency, good quality, easy to control the processing conditions, and good working conditions. With suitable abrasives, the surface roughness can reach Ra0.1μm.
In the woven mark wristband manufacturer in terms of mold polishing finish depends on the degree of product appearance quality, so the polishing process is the same is an important process, and other industries polishing process is different, relatively speaking, mold polishing is also to enhance the processing efficiency of silicone rubber and product quality, etc., so you buy the woven mark wristband product surface finish is good or bad officially depends on the mold polishing process to do a good job!
