Ili ndi bokosi la ufa la magawo awiri okhala ndi pepala lapamwamba la pulasitiki. Tsamba lapamwamba likhoza kusindikizidwa ndi machitidwe kapena zizindikiro zamalonda, zomwe zidzapangitse bokosi lonse kukhala lapamwamba kwambiri. Bokosi la ufali limakhalanso ndi chitsanzo chachifupi, chomwe ndi bokosi lopanda mbale yapamwamba, koma miyeso ina yamkati ndi yofanana. Monga chitsanzo, ife electroplated mbali iliyonse ya bokosi. Monga chinthu chomwe makasitomala amayenera kuyitanitsa, titha kupereka umisiri wosiyanasiyana wamankhwala apamwamba, monga kupopera mbewu mankhwalawa gradient / utoto wa rabara / utoto wa matte, kukwaniritsa zosowa zosiyanasiyana za makasitomala.
