Why should precision stamping molds be polished? L-g?an ewlieni tal-illustrazzjoni huwa darbtejn. L-ewwel nett, jista’ j?id il-lumino?it à tal-mold u jtejjeb id-dehra estetika tal-bi??a tax-xog?ol. It-tieni nett, dan jista’ jag?mel il-mold fa?li biex jin?el. Wara, l-EMAR se jie?u lilek biex tifhem il-metodi l-aktar komuni tal-illustrazzjoni g?at-timbru pre?i?.
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 can be smoothed by removing small protrusions on the material surface through electrolytic polishing. Compared with chemical polishing, it can eliminate the influence of cathodic reactions and achieve better results.
3. I??arrar ultrasoniku: Po??i l-materjal li g?andu ji?i ??arrat f’sospensjoni tat-t?in u po??ih flimkien f’kamp ultrasoniku. Imbag?ad, permezz tal-os?ilazzjoni ta’ mew? ultrasoniku, il-abra?iv huwa mit?un u ??arrat fuq il-wi?? ta’ bi??iet tax-xog?ol stampati bi pre?i?joni. L-ippro?essar ultrasoniku g?andu forza makroskopika baxxa u mhux se jikkaw?a deformazzjoni tal-bi??a tax-xog?ol, i?da se jag?mel il-produzzjoni u l-installazzjoni ta’ bi??iet tax-xog?ol stampati bi pre?i?joni aktar diffi?li. L-ippro?essar ultrasoniku jista’ ji?i kkombinat ma’ metodi kimi?i jew elettroliti?i. Fuq il-ba?i tal-korru?joni tas-soluzzjoni u l-elettroli?i, ti?i applikata vibrazzjoni ultrasonika biex t?awwad is-soluzzjoni, u b’hekk il-prodotti ma?lula fuq il-wi?? tal-bi??a tax-xog?ol jinqalg?u u l-korru?joni jew l-elettrolit qrib il-wi?? ikunu uniformi; L-effett ta’ kavitazzjoni tal-ultrasound fil-likwidu jista’ wkoll jissopprimi l-pro?ess ta’ korru?joni, li huwa ta’ benefi??ju g?at-tis?i? tal-wi?? ta’ bi??iet tax-xog?ol stampati bi pre?i?joni.
