Dab tsi yog qhov yuav tsum tau muaj cov thawv yas ntim molding?
Lub hollow tshuab molding ntawm yas lub thawv muaj raws li ob qho nram qab no nyob rau yas.
(1) kev tsim tawm rau kev siv technology ntau lawm.
Cov khoom uas siv siv yuav tsum tau tshaj cov additives thiab concentrated masterbatch (tuab xim masterbatch, kev ua haujlwm ntawm masterbatch) thiab txawm yas.
Cov hmoov nphuab tsuas yog ib qho yas los yog cov ntaub ntawv uas siv los ua nws lub cev, nws lub hnab mos lwj yas yog txawm, qhov saum npoo av yog du thiab du.
Nyob rau hauv ntau ntawm molding kub, lub qhuav tau txaus txaus peev xwm thiab thermal stability, thiab muaj peev xwm rov qab dua thaum tsim nyog.
Lub billet tsis yog yooj yim rau nws tus kheej-luj droop, thiab muaj zoo zoo thiab ntev ntawm repetition muaj peev xwm.
Txawm tias thaum muaj kev kub ceev tensile billets, cov yas thooj ntawv yuav tsum muaj lub zog tensile txaus.
Tus billet muaj lub qhov hluav taws xob kaw kom muaj zog kom tiv thaiv tau cov hauv qab daus ntawm lub pob zeb thaum lub taum paj tawm los yog tsim
Lub tshuab raj tshuab mould ua los ntawm kev siv lub cuab yeej tuaj yeem ua hauj lwm. Txhua yam khoom yas muaj ruaj khov thiab repeatable molding thiab kev ua haujlwm.
(2) txoj cai ntawm molding txoj kev ntawm plastics.
Siv lub tshuab ua kom zoo tshaj qhov qub, qhov tawg ntawm cov dej ntws (xws li mold core) tsis pom tseeb thiab muaj zog txaus lub zog.Tus clamping seem ntawm cov billet tau zoo weld muaj peev xwm.Qhov ntxhuab txaus tus nqi ntawm cov khoom yog tsawg.
Tshuaj Txhuam Hniav Tshuab molding, ncab tshuab moulding.The kua ndlwg ntawm cov khoom siv siab, lub yaj yog yooj yim ntws, tsis muaj viscosity, thiab tuaj yeem ua rau cov hluav taws xob txaus xiao los yog polyfilm kab noj hniav.Qhov lub zog ntawm cov yaj yog tsawg dua li ntawm extrusion molding.
Xovxwm multilayer tshuab molding.Thaum ntau txheej txheej co-extrusion tshuab moulding, cov ntaub ntawv ntawm cov co-extruded txheej yuav tsum tau raws li cov txheej txheem ntawm cov khaubncaws sab nraud povtseg.Qhov nplaum txheej yuav tsum muaj txaus nplaum force.The barrier txheej yuav tsum tau raws li cov cai ntawm cov khoom rau cov khoom tsis muaj vaj tse thiab qhov khoom ua tau zoo.Yog hais tias cov txheej txheem txhawb nqa cov khoom siv zog siab zog, lwm cov khaubncaws sab nraud povtseg siv tau cov khoom siv uas tsis tshua muaj lub zog ua tau zoo dua.Qhov ntxhuab ntws tshaj tawm ntawm cov khoom siv tsawg tsawg thiab tus kheej nyhav ntawm tus billet yog tsis pom tseeb.
