Vuthela uyilo lokungunda kunye nenaliti yokubumba ukufana kunye nomahluko, kufuneka unikele ingqalelo kwintoni?

1. Inkqubo yoyilo lokubumba ukuvuthela yahlukile, uyilo lokubumba ukuvuthela sisitofu + ukuvuthela;Isitofu sokubumba sisitofu + uxinzelelo;Ukubumba umqulu yi-extrusion + uxinzelelo;Ukubumba ukuvuthela kufuneka kube nentloko eshiywe ngumbhobho wokufunxa, isitofu sokubumba kufuneka sibe necandelo lesango, ukusika iplastiki eqengqelekayo kufuneka ibene burr

Uyilo lokubumba ukuvuthela

2. Ngokuqhelekileyo, ukubumba isitofu ngundoqo oqinileyo, ukubumba ukuvuthela kunye nokubumba umqulu akunanto engundoqo.Umphezulu weendawo zokutofa uyaqaqamba, umphezulu wokuvuthela kunye nomqengqelezi weplastiki awulingani.Ukubumba ukuvuthela kunye nothelekiso lokubumba ubuncinci ubuncinci bokubumba kunomlomo ovuthuzayo.Olu luthelekiso ngokubanzi.I wonder uya understander!!

3. Ukuncipha kweeplastiki kunye nezinto ezichaphazelayo

I-Thermoplastics inepropathi yokwandisa xa ishushu, inkontileka xa ipholile, kwaye ngokuqinisekileyo iyancipha xa icinezelekile.Kwinkqubo yokubumba i-injection, iplastiki etyhidiweyo ifakwe kuqala kwi-mold cavity, emva kokuzaliswa, i-melted ipholile kwaye iqiniswe, kwaye i-shrinkage iyenzeka xa iinxalenye zeplastiki zikhutshwe kwi-mold, ebizwa ngokuba yi-shrinkage.Iinxalenye zeplastiki ukusuka kwisikhunta ukuya kuzinza kweli xesha lexesha, kuya kuhlala kukho utshintsho oluncinci kwisayizi, utshintsho luqhubeka luyancipha, le ngqungquthela ibizwa ngokuba yi-post-shrinkage.Enye inguqu kukwandiswa kweeplastiki ezithile zehygroscopic ngenxa yokufunxa ukufuma.Umzekelo, xa isiqulatho samanzi senayiloni 610 sisi-3%, ukwanda kobungakanani yi-2%;Xa isiqulatho samanzi sefibre yeglasi yokuqinisa inayiloni 66 yi-40%, ukwanda kobungakanani yi-0.3%.Kodwa ukwenza i-shrinkage kudlala indima enkulu.
