Uchungechunge lwe-SPG lucofa ukutyhala ukudibanisa isinciphisi sesantya seplastiki, isinciphisi sesantya esithe ngqo sepneumatic, esisetyenziselwa imibhobho yerhasi.
Uchungechunge lwe-SPG lucofa ucofa ucofa ukudibanisa isinciphisi sesantya seplastiki sisidibanisi esikhawulezayo esisetyenziselwa ukudibanisa imibhobho yegesi. Yamkela ilula kwaye kulula ukuyisebenzisa ukucofa okukodwa ukuyila, enokuthi idibanise ngokukhawuleza kwaye ikhuphe kwaye ikhuphe imibhobho yomoya. Olu hlobo lokudibanisa lufanelekile kwiinkqubo zemibhobho yomoya kwaye lunokubonelela ngokuqina komoya okuthembekileyo kunye nokudibanisa okuzinzile.
Umdibaniso wenziwa ngeplastiki ekumgangatho ophezulu kwaye unokumelana nokugqwesa okugqwesileyo kunye nokumelana nokunxiba. Inophawu lokukhaphukhaphu, okwenza ufakelo kunye nokusebenza kube lula ngakumbi. Ukongezelela, ukuyila kwayo kwenza ukuba isebenze kwiindawo ezinoxinzelelo oluphezulu kunye nobushushu obuphezulu, iqinisekisa ukuzinza nokuthembeka kwayo.
