Intsimbi ayisiyiyo kuphela into enokuphoswa, iplastiki nayo inokuphoswa. Izinto ezigudileyo eziphezu komhlaba ziveliswa ngokugalela izinto zeplastiki ezinolwelo kwi-mold, evumela ukuba iphilise kwigumbi okanye kwiqondo lokushisa eliphantsi, kwaye emva koko isuse imveliso egqityiweyo. Le nkqubo ibizwa ngokuba yi-casting. Izinto ezisetyenziswa ngokuqhelekileyo ziyi-acrylic, i-phenolic, i-polyester kunye ne-epoxy. Zihlala zisetyenziselwa ukwenza iimveliso ezingenanto, iiphaneli, njl., zisebenzisa iinkqubo zeplastiki ezibandakanya ukubumba idiphu, ukubumba okudaka, kunye nokubumba okujikelezayo.
(1) Yehlisa ukubumba
Ubushushu obuphezulu bokungunda bugalelwe kulwelo lweplastiki olunyibilikisiweyo, emva koko lukhutshwe kancinci, lomiswe, kwaye ekugqibeleni imveliso egqityiweyo ixotyulwe kubumba. Isantya apho ukubunjwa kususwe kwiplastiki kufuneka kulawulwe. Okukhona sicotha isantya, kokukhona ungqimba umaleko weplastiki. Le nkqubo ineenzuzo zeendleko kwaye inokuveliswa kwiibhetshi ezincinci. Ngokuqhelekileyo isetyenziselwa ukuvelisa izinto ezingenanto ezifana neebhaluni, iiglavu zeplastiki, izixhobo zesandla kunye nezixhobo zonyango.
(2) Ukubumba ukujiya
Ulwelo lweplastiki olunyibilikisiweyo lugalelwa kwi-mold yobushushu obuphezulu ukwenza imveliso engenanto. Emva kokuba iplastiki yenze uluhlu kwindawo yangaphakathi yesikhunta, izinto ezingaphezulu zithululwa. Emva kokuba iplastiki iqinile, isikhunta sinokuvulwa ukususa inxalenye. Okukhona iplastiki ihleli ekubunjeni, kokukhona iqokobhe liya kuba lingqindilili. Eli linqanaba eliphezulu lenkqubo yenkululeko enokuvelisa iimilo ezintsonkothileyo ezinenkcukacha ezintle zokuthambisa. Iimoto zangaphakathi zihlala zenziwe nge-PVC kunye ne-TPU, ehlala isetyenziswa kwiindawo ezifana nedeshibhodi kunye nezibambo zeminyango.
3) Ukubumba okujikelezayo
Ixabiso elithile leplastiki elinyibilikayo lifakwe kwi-mold evuthayo ephindwe kabini, kwaye i-mold ijikelezwe ukuze isasaze izinto ngokulinganayo kwiindonga zokubumba. Emva kokuqina, isikhunta sinokuvulwa ukukhupha imveliso egqityiweyo. Ngethuba le nkqubo, umoya okanye amanzi asetyenziselwa ukupholisa umkhiqizo ogqityiweyo. Imveliso egqityiweyo kufuneka ibe nesakhiwo esingenanto, kwaye ngenxa yokujikeleza, imveliso egqityiweyo iya kuba ne-curve ethambileyo. Ekuqaleni, isixa seplastiki engamanzi simisela ubukhulu bodonga. Ihlala isetyenziselwa ukwenza izinto ezijikelezileyo ze-axially symmetrical ezifana neembiza zeentyatyambo zomdongwe, izixhobo zokudlala zabantwana, izixhobo zokukhanyisa, izixhobo zenqaba yamanzi, njl.
