,injection molding services what is called plastic mold, six commonly used plastic mold surface polishing methods What’s a plastic mold?
Plastic mold is a composite mold for compression, extrusion, injection, blow molding and low foaming molding. With the rapid development of injection molding industry, a variety of injection mold industry, but because of industry competition, there is a gap between the quality, such as the degree of polishing gap. In modern industry, most molds need to be polished and polished, because polishing can improve the beauty of the product, but also can make the release of more simple, factory processing, saving costs. After polishing the common mold, the user needs electroplating, which can greatly improve the wear resistance and corrosion resistance of the mold. And different levels of testing face mold surface requirements are not the same, then for different levels of testing, plastic mold and the surface of what kind of polishing treatment?
Shenzhen donglai plastic mold manufacturers found six commonly used polishing treatment, to share with you to learn.
One, it’s mechanical polishing, a polishing method in which a smooth surface is obtained by cutting and plastic deformation of the material surface to remove the polished convex part. General use of oil, wool wheel, sandpaper, hand-based operation, special parts such as the surface of the rotating body, can use the turntable and other auxiliary tools, surface quality requirements can be used high-precision polishing method.
Two, chemical polishing, let the material in the chemical medium in the surface of the micro-protruding part of the concave part of the preferred solution, so as to obtain a smooth surface. The main advantage of this method is that it does not need complex equipment, and can polish the workpiece with complex shape, can simultaneously Polish many workpiece, high efficiency. No Three, it’s electrolytic polishing, the basic principle is the same as chemical polishing, that is, by selective dissolution of the material surface of small protruding parts, so that the surface smooth. Compared with chemical polishing, the effect of cathodic reaction can be eliminated and the effect is better.
Four, it’s ultrasonic polishing, the workpiece is put into the abrasive suspension and placed in the ultrasonic field together. The abrasive is ground and polished on the surface of the workpiece by the oscillating action of the ultrasonic wave. On the basis of solution corrosion and electrolysis, ultrasonic vibration is applied to agitate the solution to make the dissolved products on the surface of the workpiece separate, and the corrosion or electrolyte near the surface is even Ultrasonic cavitation in the liquid can also inhibit the corrosion process and is conducive to surface brightening.
Five, it’s fluid polishing, the high-speed flowing liquid and the abrasive particles carried by it scour the surface of the workpiece to achieve the goal of polishing. Common methods are: abrasive jet processing, liquid jet processing, such as hydrodynamic grinding. Hydrodynamic lapping is driven by hydraulic pressure, which makes the liquid medium carrying abrasive particles flow across the surface of the workpiece at high speed. The medium is mainly made of special compound (polymer-like material) with good flow performance at low pressure and mixed with abrasive, which can be made of silicon carbide powder.
6, is a magnetic abrasive polishing, the abrasive brush is formed by using magnetic abrasive under the action of magnetic field to grind the workpiece. The method has the advantages of high processing efficiency, good quality, easy control of processing conditions and good working conditions. The polishing treatment of plastic mold plays an important role in the quality and appearance of the mold. Different polishing methods are suitable for different mold surface requirements, and the selection of suitable polishing methods can improve the life of Mold and product quality. It is hoped that the six common polishing methods of plastic mould can help the mould manufacturers and practitioners, and improve the production level and market competitiveness of plastic mould.
