Understand The Detailed Process Of Mold Surface Polishing For Silica Gel Products!

Each product do not want the product surface is uneven, pitted face, so for the surface finish of the silicone products is important, silica gel products main die polishing method is mainly to reduce the roughness on the surface of the die steel, to really ensure the surface finish of the silicone products still need to begin from mold process above, so for the silicone mold surface finish process what are the treatment?Mold polishing can be divided into a variety of processes. Different processing methods are used in silica gel molds, among which the following surface treatment methods are common processes.Electrolytic polishing:Electrolytic polishing relies on selective dissolution of the surface of the material by a small convex part, so that the surface smooth. Compared with chemical polishing, the effect of cathode reaction can be eliminated. The electrochemical polishing process is divided into two steps:(1) the macroscopic leveling dissolution product diffuses into the electrolyte, and the material surface geometric roughness drops. Ra>.(2) low light level anode polarization, surface brightness increased,Ra<1 oxidation m.Mechanical polishing:Mechanical polishing is to rely on cutting surface Plastic deformation after removed by polishing the convex part of the smooth surface polishing method, commonly used article oil stone, wool wheel, abrasive paper, etc., with manual operation is given priority to, special components such as surface of solid of revolution, can use tools such as turntable, high surface quality can be used over lapping method. Super precision polishing is a special grinding tool. In the grinding fluid containing abrasive, it is pressed tightly on the workpiece's processed surface for high-speed rotary motion. The Ra0.008 surface roughness can be achieved with this technology, which is the highest among all polishing methods.Ultrasonic polishing:Ultrasonic polishing is the use of ultrasonic as power, promote small abrasive impact surface at high speed, forcing the abrasive on the machining surface, thus reducing its polishing method of table surface roughness.Fluid polishing:Fluid polishing relies on high speed fluid flow and the abrasive particles it carries to scour the surface of the workpiece to achieve the purpose of polishing. Common methods are: abrasive injection processing, liquid injection processing, hydrodynamic grinding and so on. Hydrodynamic grinding is driven by hydraulic force, so that the liquid medium carrying the abrasive particles reciprocates through the workpiece surface at high speed. The medium is mainly made of special compounds with good flow performance under low pressure and is mixed with abrasive, which can be made of silicon carbide powder.Magnetic grinding and polishing:Magnetic grinding and polishing is to use magnetic abrasive to form a abrasive brush under the action of magnetic field to grind the workpiece. This method has high processing efficiency, good quality, easy control of processing conditions and good working conditions. With proper abrasive, the surface roughness can reach Ra0.1 degree Celsius.In the silicone products manufacturer in mold polishing finish degree depends on the appearance quality of the product, so the same process of polishing is an important working procedure, different from other industries polishing process, relatively mold polishing is to enhance the processing efficiency of silicone rubber products and the quality of the products, and so on, so you buy the silicone product surface finish is good formal depends on the polishing process of mold is good!
