Yuav ua li cas thiaj txiav txim seb qhov txhaj tshuaj molding tshuab barrel kub teeb yog qhov tsim nyog?

Txhawm rau txiav txim seb puas muaj qhov ntsuas kub ntsuas ntawm kev txhaj tshuaj molding tshuab yog tsim nyog los ua kom tiav cov khoom siv ntawm cov kev txiav txim siab thiab cov txheej txheem kev txiav txim siab tshwj xeeb thiab cov kauj ruam:
{{01. Cov ntaub ntawv tseeb raws li cov yam ntxwv ntawm cov khoom siv raw
Cov Khoom Siv Khoom Siv Hluav Taws Xob
Txhua yas yas, pp, PC, nylon, thiab lwm yam {.
ABS: Kev ua qhov kub yog feem ntau 200 ~ 250 degree, thiab nws yuav decompose yog tias ntau dua 260 degree;
PC: Kev ntsuas kub yog 2820 Degree, thiab kev siv tau yooj yim kuj yuav tsis zoo yog tias nws qis dua 270 degree.
Ntu kub: seb qhov kub ntawm txhua ntu (tshwj xeeb tshaj yog cov khoom siv tau tso cai los ntawm ntau tshaj 10 ~ 20 degree.
Soj ntsuam lub xeev melting ntawm cov ntaub ntawv raw
Thaum ua ntej molding manually, soj ntsuam cov tsos ntawm yaj ntawm lub ntsia hlau tawm:
Tsim nyog qhov kub: cov yaj yog niaj hnub hnav, glossy, thiab tsis muaj qhov pom tseeb lossis kev tsis txaus ntseeg;
Qhov kub thiab txias tsawg dhau: cov yaj tau sib xyaw nrog cov nplais uas tsis tau sib xyaw, qhov saum npoo yog ntxhib, thiab cov ntsia hlau torque yuav nce ntxiv;
Kub heev dhau lawm: melt yog daj, muaj hlawv pob, thiab txawm tias cov pa luam yeeb dub (decomposition) .
2. rov qab los ntawm cov khoom lag luam tsis xws luag
Irrational chim siab yuav ncaj qha rau cov yam tsis xws luag, thiab qhov teeb meem kub tuaj yeem txiav txim los ntawm cov yam ntxwv tsis xws li:
Kev ua kom raug qhov tshwm sim ua tau cov txheej txheem ntsuas kub
Kev tsis zoo yas (cov khoom siv paj, nyiaj xaim) lub thoob kub yog tsawg heev los xyuas seb qhov ntsuas kub tsis tshua yog qis dua ntawm qhov chaw pub mis thiab compression ntu yog qis dua li lub ntsiab lus melting
Hlawv, dub me ntsis hauv zos yog siab dhau (xws li nozzle lossis lub sijhawm nyob ntev dhau ntawm cov ntsuas kub thiab ntsuas kom tsis txhob muaj cua sov
Flash, burrs lub yaj fluticity yog qhov muaj zog heev (cov kub kub ua rau cov dej ntws tsawg dua) txo cov kub txog 10 ~ 20℃thiab saib seb puas txo qis
Tsis muaj khoom siv, tsis muaj qhov ntsuas qhov kub tsawg dhau, ua rau muaj kev tsis txaus siab nce qib 10℃los ntsuas seb qhov puv yog zoo dua
Pom cov cim txaus thiab cov cim vuam tsis muaj qhov kub thiab txias tsis yog qhov kub thiab txias ntawm txhua ntu
Shrinkage, dents cov dej txias heev dhau lawm (kub dhau los ua kom lub ntsej muag kub tsis sib haum) nce pwm kub los sis ntsuas kub kom txhim kho lub siab tuav cov nyhuv tuav tau
Iii {. Tshawb xyuas qhov sib xws ntawm qhov ntsuas kub thiab ntsuas cov khoom siv
Thermocouple thiab Cua Sov Nplhaib xwm txheej
Ua tsis tiav ntawm lub chrel kub sensor (thermocouple) lossis kev puas tsuaj rau lub nplhaib cua kub yuav ua rau muaj qhov kub thiab txias rau cov nqi teev .
Txoj kev kuaj pom:
Siv tus pas ntsuas kub infrared los ntsuas lub barrrel qhov chaw kub thiab piv nws nrog lub maub los saib tus nqi (pub dhau los, lub sensor xav tau calibrated lossis hloov);
Saib xyuas cov cua sov / Txias qhov tam sim no thaum cua sov, thiab seb qhov ntsuas kub thiab txias thaum txias .
Mlot Kub Ntsuas
Txheeb xyuas cov xwm txheej melt los ntawm "txhaj tshuaj ntsuas":
Tsis txhob muaj ntau lawm, manually tshem cov kua nplaum rau hauv lub thawv huv, thiab saib seb puas yog cov yaj tsis zoo, ua rau muaj kev cuam tshuam lossis tsis txaus ntseeg;
Yog tias cov neeg mob tso cai, siv tus ntsuas kub yaj ywm yaj (xws li tso tawm thermocouple) kom raug kaw rau ntawm pawg mezzle tshooj kub (

Kauj Ruam Kev Ntsuas Kub
Rau cov ntaub ntawv raw tshiab lossis tsis paub txog qhov ntsuas kub, cov txheej txheem hauv qab no tuaj yeem siv rau kev kuaj:
Teeb tsa qhov pib kub rau cov nruab nrab ntawm cov kev pom zoo ntawm cov khoom;
Sim txhaj tshuaj molding 1 ~ 2 pwm thiab saib cov khoom lag luam tsis xws luag;
Yog tias txhaws tsis txaus, nce 5 ~ 10℃txhua lub sijhawm (tsom rau kev kho ntu metering thiab nozzle txias); Yog hais tias flash lossis hlawv tshwm sim, txo 5 ~ 10℃txhua lub sijhawm;
Sau cov ntsuas kub sib xws sib xws nrog lub xeev zoo tshaj plaws .
Soj ntsuam cov ntsia hlau thauj khoom thiab rov qab lub siab
Ntawm qhov kub uas tsim nyog, lub zog yog ruaj khov yog ruaj khov thaum lub zog ua ntej-molding thiab kho rov qab raws li cov khoom siv, xws li PC rov qab siab 5 ~ 10BAR);
Yog tias cov ntsia hlau nyuaj rau tig (torque yog siab dhau), qhov kub yuav qis dhau; Yog tias lub sijhawm ua ntej ua ntej nrawm nrawm nrawm nrawm nrawm thiab cov txiv qhuav yuag dhau, qhov kub thiab txias heev .

Sib xws ntawm kev tsim khoom txuas ntxiv
Ntawm qhov ntsuas kub uas tsim nyog, cov khoom lag luam loj, thiab cov tsos yuav tsum ruaj khov (xws li tsis muaj sijhawm ib zaug (xws li tsis muaj peev xwm ib zaug txhua 10 .
Txheeb xyuas qhov ntev ntawm cov khoom lag luam tsis tu ncua (xws li txhua teev) {}}} Seb puas ruaj khov, xws li seb puas ruaj khov kho) .
Barrel Huv thiab Cov Chaw Nyob
Tom qab cheem, rhuav tshem cov ntsia hlau thiab nozzle kom pom tias puas muaj cov pa roj carbonized nyob sab hauv:
Ib qho me me ntawm lub teeb xim zoo nkauj (tsis hlawv) yog qhov qub;
Scorch Scorch cim lossis lumps qhia tau tias qhov kub thiab txias dhau lossis hauv zos dhau ntawm Circuit Court hauv cov cua sov chev) {}}}}
VI .} Kev ceev faj
Rationalalal ntawm chim Segment Kub
Feem ntau qhov kub ntawm seem seem yog qis dua li ntawm ntu compression), kom tsis txhob ua rau cov khoom siv ua kom zoo dua li ntawm ntu ntawm ntu (kom txo qis ntu);
Lub surlite kub txwv ntawm cov ntaub ntawv kub-rhiab (xws li PVC thiab pom) yuav tsum tau nruj me ntsis tswj kom tsis txhob muaj kev sib cav.
Kev cuam tshuam ib puag ncig thiab khoom siv
Thaum chav tsev kub dhau heev (xws li nyob rau lub caij ntuj no), cov cua sov dissipation ntawm lub thoob tau nrawm, thiab cov teeb meem kub yuav tsum tau nce ntxiv;
The barrel wear of old equipment may cause melt retention, and the temperature needs to be slightly lowered to reduce the risk of decomposition.
Cov ntsiab lus ntawm cov txheej txheem kev txiav txim
Kev soj ntsuam pib: paub meej tias qhov ntsuas kub tau ntsib cov khoom siv tshwj xeeb, thiab lub ntsuas thiab lub nplhaib cua sov yog qhov qub;
Pwm Trova: Saib cov khoom lag luam tsis xws luag thiab pom qhov kub ntawm qhov kub txog qib theem ntawm kauj ruam kev hloov kho;
Kev Ntsuas: Pom qhov sib xws ntawm lub xeev melt thiab qhov tseeb kub thiab cov nqi qhia tau;
Kev ua kom zoo: kho cov tsis sib xyaw ua ke nrog ntsia hlau thauj khoom, rov qab siab, thiab lub sijhawm ruaj khov.
Los ntawm cov txheej txheem saum toj no, nws yog qhov ua tau rau cov kev txiav txim siab tsis zoo yog tsim nyog thiab daws cov teeb meem moulding tsis tsim nyog rau hauv lub hom phiaj tsis raug rau hauv lub hom phiaj tsis raug {}}
