Uma ukhetha ama-caster, uvame ukubhekana nokukhetha phakathi kokukhetha i-TPR (irabha ye-thermoplastic) nezinto ze-nylon. Namuhla, ngizohlola izici, izinzuzo kanye nokungalungi kwalezi zinto ezimbili ukuze ngikusize wenze isinqumo esinolwazi oluthe xaxa.
I. Abaqaphi be-TPR
I-TPR iyinto yerabha ye-thermoplastic enokuqina okuhle nokumelana nokuguguleka, ama-TPR casters avame ukuba nomthelela ongcono kanye nokumelana nokugqwala, futhi ayakwazi ukuzivumelanisa nezimo kangcono nomhlabathi onzima. Ngaphezu kwalokho, ama-TPR casters anobumnene obuthile, azizwa kahle, akulula ukubangela umsindo endaweni ezungezile.
Kodwa-ke, ama-TPR casters nawo anemikhawulo yawo. Ngenxa yokumelana kwawo nokushisa okuphezulu, ngokuvamile cishe ku-70-90 ℃, ngakho-ke awafanele ukusetshenziswa endaweni ethile yokushisa okuphezulu. Ngaphezu kwalokho, amandla okuthwala ama-TPR casters aphansi kakhulu, okungase kungafaneleki kwezinye izimo zokuthutha ezinzima.
Okwesibili, ama-caster e-nylon
Inayiloni iyinto eyenziwe nge-resin yokwenziwa enamandla aphezulu kanye nokumelana nokuguguleka. Ama-caster enayiloni ngokuvamile anomthamo ophezulu womthwalo kanye nokumelana nokushisa okuphezulu, okuyinto enhle ekuthuthweni okunzima kanye nendawo yokushisa ephezulu. Ngaphezu kwalokho, ama-caster enayiloni anokusebenza okungcono kokujikeleza futhi anganikeza isipiliyoni sokuhamba esibushelelezi.
Kodwa-ke, ama-caster e-nylon avame ukubiza kakhulu futhi angase angafaneleki kwezinye izikhathi ngesabelomali esilinganiselwe. Ngaphezu kwalokho, ama-caster e-nylon anamandla amancane okumelana nokushayisana futhi angadinga ukuvikelwa okwengeziwe phansi okuqinile.
Ngokwezici ze-TPR kanye ne-nylon casters, kunconywa ukuthi ukhethe ngokwezidingo zangempela. Kwezinye izigcawu ezidinga ubumnene nenduduzo, njengekhaya nehhovisi, i-TPR casters ingaba yisinqumo esihle. Kwezinye izigcawu ezidinga umthwalo ophezulu kanye nokumelana nokushisa okuphezulu, njengezimboni kanye nezindawo zokugcina impahla, i-nylon casters ingaba ngcono.
