Njengomenzi wezinto zokubumba eTshayina, xa kuthelekiswa nezinto zokubumba zasekhaya, amaxabiso okubumba angaphezulu kakhulu kwiminyaka edlulileyo, umsantsa ubangelwa ngumgangatho we-diffriend. I-American Society of Plastic Industry (SPIAN-102-78) yahlula i-mold ibe ziindidi ezintlanu. Ezi ntlobo zintlanu zezinto zokubumba zineemfuno ezahlukeneyo, kwaye umgangatho wokwahlukanisa usebenza kuphela ukufanisa umatshini wokujova osebenza ngaphantsi kweetoni ezingama-400.

Umjikelo wobomi uphindaphinda ukuya kuthi ga kwisigidi esinye, okhethekileyo kumandla aphezulu emveliso yemveliso. Ukukhetha intsimbi yokubumba efanelekileyo yokwenziwa, ehambelana nale nqanaba lokubumba kufuna ixabiso eliphezulu. Iimfuno ziboniswe ngolu hlobo lulandelayo:

(1) Kufuneka ube nolwazi oluneenkcukacha ngoyilo lwesikhunta.
(2) Iimfuneko zobunzima besiseko sesikhunta ubuncinci yi-BHN280 (HRC30).
(3) Umphezulu womngundo (kubandakanya imingxunya kunye nemingxunya engundoqo) ubuncinci kuluhlu lobunzima be-BHN450 (48HRC), zonke ezinye izixhobo ezifana nezilayida, izilifti, izilifti ezithe tye, njl.njl. kufuneka ziqine.
(4) Inkqubo yokukhupha umoya kufuneka ibe nenkqubo ekhokelayo.
(5) Isilayida esisecaleni kufuneka sifakelwe ipleyiti yokuguguleka.
(6) I-Cavity mold, i-core mold, i-slider kunye nezinye iindawo kwi-mold kufuneka zifakelwe nge-sensor-sensitive.
(7) Ngokuphathelele ubomi bokubumba, umgangatho wemveliso uya kuncipha okanye ixesha lokujikeleza kokubumba liya kwandiswa ngenxa yokuba umbhobho wamanzi opholileyo wawudlaka imihla ngemihla, ngoko ke ii-inserts okanye ii-mold plates zacetyiswa ukuba zenze unyango lokulwa nokubola.
(8) Zonke ezi zixhobo zokubumba ezikumgangatho ophezulu mazifakelwe indlela yokubamba iingcingo kumgca wokuqhawula.

Umjikelo wobomi uphindaphinda ukuya kuthi ga kwi-500,000 ukuya kwi-1,000,000 amaxesha. Ukuvelisa iimveliso ezinkulu, kuya kusetyenziswa intsimbi esemgangathweni ophezulu ukuvelisa ixabiso elibizayo. Iimfuno zezi zilandelayo:

(1) kufuneka babe nolwazi oluneenkcukacha ngoyilo lwesikhunta.
(2) Iimfuneko zobunzima besiseko sesikhunta ubuncinci yi-BHN280 (HRC30).
(3) Ubunzima bomphezulu kunye nobunzulu bomphezulu ongaphakathi kufuneka bube kuluhlu lwe-BHN540 (HRC 48), zonke ezinye izixhobo ezisebenzayo kufuneka ziphathwe ngobushushu.
(4) Faka isixhobo sokuvavanya ubushushu kwi-cavity mold, i-core mold, ii-sliders kunye nezinye iindawo ezinokwenzeka.
(5) Zonke iimolds zolu hlobo mazifakelwe indlela yokubamba iimolds phakathi komphezulu womgca wokwahlulahlula.
(6) Amathuba ezi zinto zingezantsi ayafuneka okanye awafuneki, kuxhomekeke kubungakanani bomveliso yokugqibela. Kucetyiswa ukuba ezi zinto nazo zenze ikowuteshini eqinisekisiweyo.
Inkqubo yokuqondisa i-Ejector, ipleyiti yokunxiba yeSlider, i-anti-erosion Colling manifold, i-Electroplating kwi-cavity mold (echasene nokugqwala).

Ixesha lokujikeleza ukuya kuthi ga kwi-500,000 amaxesha. Isetyenziswa njengemveliso ephakathi yeemveliso, ixabiso lifanelekile. Iimfuno zezi zilandelayo:

(1) kufuneka babe nolwazi oluneenkcukacha ngoyilo lwesikhunta.
(2) Iimfuneko zobunzima besiseko sesikhunta ubuncinane yi-BHN165 (HRC17).
(3) ii-cavity kunye nee-core molds kufuneka zibe nobunzima obuyi-BHN280 (HRC30) ubuncinane nangaphezulu.
(4) zonke ezinye izincedisi zikhululekile ukuzikhethela ngababoneleli.

Umjikelo wobomi uphindaphinda ukuya kuthi ga kwi-100,000. Kwimveliso esemgangathweni, ukumelana nokuguguleka kwezinto zokubumba akuphezulu, ixabiso liphantsi kunelesiqhelo. Iimfuneko zezi zilandelayo:

(1) Cebisa ukubonelela ngolwazi loyilo lwesikhunta.
(2) Isiseko sokubumba singaba yintsimbi ethambileyo okanye isinyithi se-aluminium.
(3) Isikhunta esingaphakathi sinokuba yintsimbi ye-aluminiyam, intsimbi ethambileyo okanye ezinye izinto ezinokuchongwa.
(4) Zonke izincedisi zikhululekile ukuzikhethela ngababoneleli.

Amaxesha omjikelo angadluli amaxesha angama-500. Isetyenziselwa ukuvelisa inani eliqingqiweyo lesampulu yokuqala, ixabiso liphantsi kakhulu. Iimfuneko zezi zilandelayo:

Isakhiwo sokubumba sinokuba yinto edityaniswe ngombane, i-epoxy resin, okanye ezinye izinto ezinika amandla aneleyo okuvelisa inani elincinci lamalungu.
