Why should precision stamping molds be polished? The main purpose of polishing is twofold. Firstly, it can increase the brightness of the mold and improve the aesthetic appearance of the workpiece. Secondly, it can make the mold easy to demold. Next, EMAR will take you to understand the most common polishing methods for precision stamping.

1. Mechanical polishing: Mechanical polishing is a method of polishing a smooth surface by removing the convex parts after polishing through deformation processes such as cutting precision stamping molds and plastic deformation of material surfaces. For precision stamping workpieces with high surface quality requirements, ultra precision polishing can be used. Ultra precision polishing uses specially designed grinding tools, which are pressed tightly against the surface of the workpiece to be processed in a polishing solution containing abrasives, and perform high-speed rotational motion.

2. Electrolytic polishing: Precision stamping molds kapab être plus pa retire ti protrusions sou materyèl la sifas nan electrolytic polishing. Compare ak chimik polishing, li kapab eliminate enfliyans de reyaksyon katòd Et rezoud pi bon rezilta.

3. Ultrasonic polishing: mete materyèl la pou être polished nan yon suspension faible epi mete l' ansanm nan yon jaden ultrasonic. Lè sa a, à oscillation de ultrasonic ond, la abrasiv se tè ak polished sou sifas de travay pwecision stamped. Ultrasonic pwosesis gen faible macroscopic fòs epi p'ap koze deformation de kote travay la, men li ap fè a pwodwi ak instalasyon de travay presyon pi difisil. Entèraksyon Ultrasonic ka konbine ak chimik ou electrolytic metòd. Yo ki baze de solisyon koresyon ak electrolysis, ultrasonic vibrasyon aplike pou styre solisyon an, ki koze ki te kraze pwodwi ki sou sifas lavil la pou detach Et la corrosion ou electrolyte prèske sifas la pou fè uniform; Cavitation efè ultrasound nan likid ka tou supprimer pwosè kòrozyon an, ki bon pou sifas ki briye de travay presyon stampe.
