Indlela yokulawula uxinzelelo lwangemva yomatshini wokubumba inaliti ye-hydraulic iyachazwa. Le ndlela ifezekisa ukulawula uxinzelelo lwangemva ngexesha lesigaba sokugcinwa kwezinto ngokufaka i-valve yokuqala yokulawula i-valve, i-valve yesibini yokulawula, i-sensor ye-pressure sensor, kunye ne-valve ye-throttle phakathi kwe-cylinder injection kunye ne-oil tank. Xa i-hydraulic injection molding machine ingena kwisigaba sokugcina izinto eziphathekayo.
I-A kunye ne-T ye-valve yokuqala yokulawula i-valve ivuliwe, iqalisa ukubuyiswa kweoli. I-oyile evela ngasemva kwe-cylinder ye-injection igeleza kwi-tank yeoli ngokusebenzisa i-valve yokulawula indlela yokuqala kunye ne-valve ye-throttle. Ngexesha elifanayo, i-B kunye ne-P ye-valve yokulawula i-valve yesibini ivuliwe, ivumela i-oyile ukusuka kwi-tank yeoli ukuba iqhube ngasemva kwe-cylinder ye-injection ngepompo yeoli kunye ne-valve yesibini yokulawula. Ngeli xesha, umlawuli we-PID uqokelela ngokuqhubekayo ixabiso loxinzelelo olufunyenwe yinzwa yoxinzelelo kwaye unqume ukuzinza koxinzelelo lwangasemva olusekelwe kwixabiso loxinzelelo oluqokelelweyo. Xa uxinzelelo lwangasemva lungazinzanga, umlawuli we-PID ulawula isantya sokuphuma kwempompo yeoli yomatshini wokubumba we-hydraulic injection ngokulawula i-motor ukuzinzisa uxinzelelo lwangasemva. Iadvanteji kukuchaneka kolawulo oluphezulu, okwenza ukuba{5}}ulawulo loxinzelelo oluphezulu oluchanekileyo.
