KhoobTshuab MouldingThev naus laus zis yog ib qho ntawm cov thev naus laus zis rau cov yas ua. Hollow tshuab moulding cov khoom yog dav siv nyob rau hauv ntau yam kev lag luam, ntim, fwj dej fwj.
Kab lus no yuav piav qhia cov teeb meem zoo uas yuav tshwm sim hauv hollow tshuab moulding pwm thiab qhia luv luv piav qhia txog kev sib tham.
1. Cov khoom lag luam loj hauv cov khoom hnyav
Vim li cas:
Kev hloov pauv hauv parison;
Tsis sib xyaw sib xyaw ntawm cov khoom siv raw;
Thaiv lossis bridging ntawm ntu pub noj, uas ua rau tsis ruaj khov extrusion; HOLLOW TSHUAB MOULDING khoom
Tsis ruaj ntseg extruder ceev.
Txoj kev:
Tshawb xyuas thiab kho cov phab ntsa tuab tswj ntaus ntawv los ua tus khub tswj hwm tau ruaj khov;
Siv cov khoom haum haum sib xyaw thiab tsim nyog txuas lub sijhawm sib xyaw kom sib xyaw cov khoom nyoos.
Kuaj seb puas muaj kev thaiv lossis lwm yam teeb meem txawv teb chaws thaiv cov dej inlet;
Tsim nyog txo cov pa hauv qhov kub kom tsis txhob muaj "Choj" tshwm sim;
Kuaj seb puas muaj lub cev muaj zog extruder yog qhov txawv txav, seb lub cev muaj zog thiab cov thawv ntim tau xoob xoob lossis ua kom pom tseeb, thiab xyuas kom meej tias qhov nrawm yog qhov ruaj khov;
Nyob rau tib lub sijhawm, peb kuj yuav tsum tshawb xyuas cov hluav taws xob nplai tsis tu ncua kom tsis txhob hloov pauv ntawm qhov ntsuas ntsuas cuam tshuam rau kev txiav txim siab zoo;
2. Cov peev xwm tsis txaus
Vim li cas:
Lub shrinkage tus nqi ntawm cov ntaub ntawv nyoos ntawm cov hom sib txawv yuav sib txawv, thiab tshuab moulding kub thiab cov laj thawj ntawm cov khoom lag luam ntau dhau thiab shrinkage ntawm cov khoom.
Peb yuav tsum tshawb xyuas thiab daws cov teeb meem hauv kev xav ua kom lub shrinkage tus nqi ntawm cov khoom lag luam tsis pub dhau ib haiv neeg.
Ib qho ntxiv, lub phab ntsa tuab ntawm cov khoom yog cov tuab heev lossis tsis sib xws, ua rau muaj kev cuam tshuam, concave sagging. Cov tsos ntawm cov khoom lag luam tsis tau raws li qhov kev cia siab thiab cov ntim tsis tau raws cov qauv.
Cov hau kev:
Kho thiab txhim kho cov pwm kom tau raws li lub suab nrov theoretical yuav tsum ua ntej;
Hloov cov ntaub ntawv raw nrog me me shrinkage, txuas lub tshuab moulding sijhawm, txo cov pwm txias txias, thiab txo qis cov dej nyab ntawm cov khoom tiav;
Kho lub phab ntsa thickness maub los ua kom lub phab ntsa thicknessy flyly faib thiab daws cov teeb meem ntawm tus kheej ntu yog sunken thiab deformed;
Lub sijhawm tsim nyog kho lub sijhawm los ua cov khoom lag luam raws cov hom phiaj tsim;
Los yog daws cov teeb meem los ntawm kev tsim nyog nce lub tshuab moulding siab.
