Umshini wokucubungula i-pinhole esheshayo usebenza kakhulu ekucubunguleni insimbi engenasici, insimbi eqinile, i-alloy enzima, ithusi, i-aluminium nezinhlobo ezahlukene zokwenza izintoIngangena ngqo noma ibhoboze kusuka ebusweni be-cant, camber kanye ne-pyramidal. Umshini usebenza ekucubunguleni i-pinhole ejulile engalawuleki njengokufaka intambo yensimbi yokusika ezintweni eziqhuba kanzima, ukuvula umlomo wombhobho wepompo ka-oyela, i-spinneret orifice yokuphotha okufayo, indlela kawoyela yezingxenye ze-hydropneumatic nomgodi wokupholisa wenjini.
