Umatshini wokubumba wokutofa
Umatshini wokubumba wokutofa wahlulwe ube ziiyunithi ezi-2 okt iyunithi yokubambelela kunye neyunithi yokutofa.
Imisebenzi yeyunithi yokudibanisa ivula kwaye ivale i-die, kunye nokukhutshwa kweemveliso.Kukho iintlobo ezi-2 zeendlela zokubambelela, ezizezi, uhlobo lokuguqula oluboniswe kumzobo ongezantsi kunye nodidi oluthe ngqo lwehydraulic apho isikhunta sivulwa ngqo kwaye sivalwe ngecylinder yehydraulic.
Imisebenzi yeyunithi yokutofa kukunyibilikisa iplastiki ngobushushu emva koko kugalelwe iplastiki enyibilikisiweyo kumngundo.
Isikrufu sijikeleziswa ukuze sinyibilike iplastiki evela kwihopha kwaye iqokelele iplastiki etyhidiweyo phambi kwesikrufu ( esiya kubizwa ngokuba yimitha ) .Emva kokuba inani elifunekayo leplastiki etyhidiweyo iqokelelwe, inkqubo yokutofa ijongwa.
Ngelixa iplastiki etyhidiweyo iqukuqela ekubumbeni, umatshini ulawula isantya esishukumayo sesikrufu, okanye isantya sokutofa.Kwelinye icala, ilawula uxinzelelo lokuhlala emva kokuba iplastiki etyhidiweyo igcwalise imingxuma.
Isikhundla sotshintsho ukusuka kulawulo lwesantya ukuya kulawulo loxinzelelo lusetwa kwindawo apho imo ye screw okanye inaliti yoxinzelelo ifikelela kwixabiso elithile elimiselweyo.
Ngundo
Umngundo yibhloko yesinyithi enomngxuma apho iplastiki enyibilikisiweyo itofwa ngayo ukusuka kwimilo ethile engatshintshiyo.Nangona zingaboniswanga kumzobo oboniswe ngezantsi, eneneni mininzi imingxuma egrunjiweyo kwibhloko yokulawula ubushushu ngamanzi ashushu, i-oyile okanye izifudumezi.
Iplastiki enyibilikisiweyo iqukuqela ingene kumngundo ngesprue ize izalise imingxuma ngendlela yeembaleki namasango.Emva koko, ukubumba kuyavulwa emva kwenkqubo yokupholisa kwaye intonga ye-ejector yomatshini wokubumba inaliti ityhala ipleyiti ye-ejector yokubumba ukukhupha ngakumbi ukubumba.
Ukubumba
Ukubumba kwenziwa ngesprue ukwazisa intlaka etyhidiweyo, imbaleki yokuyikhokelela kwimingxuma, kunye neemveliso.Ekubeni ukufumana imveliso enye kuphela ngeshothi enye kungasebenzi kakuhle, umngundo udla ngokuyilwa ukuba ube nemingxuma emininzi edityaniswe nembaleki ukuze iimveliso ezininzi zenziwe ngokudubula okunye.
Ukuba ubude bomgijimi kwi-cavity nganye buhluke kule meko, i-cavities ayinakuzaliswa ngaxeshanye, ukwenzela ukuba imilinganiselo, ukubonakala okanye iipropathi zokubumba zihlala zihluke kwi-cavity by cavity.Ngoko ke imbaleki idla ngokuyilwa ukuze ibe nobude obufanayo ukusuka kwi-sprue ukuya kumngxuma ngamnye.
Ukusetyenziswa kwemathiriyeli ehlaziyiweyo
I-Sprues kunye nabagijimi phakathi kokubumba azikho imveliso.Ezi zahlulo ngamanye amaxesha ziyalahlwa, kodwa kwezinye iimeko zicolwa ngokutsha kwaye ziphinde zisetyenziswe njengezinto zokubumba.Ezi zixhobo zibizwa ngokuba yimathiriyeli ehlaziyiweyo.
Iimathiriyeli eziphinde zacutshungulwa azisebenzi kuphela njengezinto zokubumba kodwa zihlala zisetyenziswa emva kokudityaniswa neepellets ezinyulu, kuba kukho ukuwohloka kweempawu ezahlukeneyo zeeplastiki ngenxa yenkqubo yokuqala yokubumba.Umlinganiselo ophezulu ovumelekileyo womlinganiselo wezinto ezihlaziyiweyo malunga ne-30%, kuba umlinganiselo ophezulu kakhulu wezinto ezihlaziyiweyo ungonakalisa iimpawu zokuqala zeeplastiki ezisetyenzisiweyo.
Kwiipropati xa kuphinda kusetyenziswe imathiriyeli, nceda ubhekisele "kwisakhono sokuhlaziya" kwisiseko sedatha yeplastiki.
Imeko yokubumba
Isimo sokubumba sithetha ubushushu be-cylinder, isantya sokutofa, ubushushu bokubumba njl njl. Ukuseta kumatshini wokubumba ukuze kufumaneke ukubumba okufunekayo, kunye nenani leendibaniselwano zeemeko ezingenakubalwa.Ngokuxhomekeke kwiimeko ezikhethiweyo, ukubonakala, imilinganiselo, kunye neempawu zomatshini zeemveliso ezibunjiweyo zitshintsha kakhulu.
Ke ngoko, itekhnoloji ezame kakuhle kunye namava afunekayo ukukhetha iimeko ezifanelekileyo zokubumba.
Iimeko zokubumba eziqhelekileyo zezixhobo zethu ziboniswe ngezantsi.Nceda ucofe imouse kula magama alandelayo eeplastiki.
