Kev tshaj lij chaw tsim khoom ntawm cov tshuab thermoforming.
1. Kev teeb tsa
Qhov sib txuam ntawm qhov kub sib sau tuag thiab lub tshuab yog qhov tseem ceeb heev, yog li kev tuag yuav tsum tau ua raws li lub tshuab siv ua ntej qhib qhov tuag. Kev hloov pauv tsis tu ncua yuav tsum zam thaum tsim khoom. Vim hais tias nyob rau hauv kev hloov ntawm pwm, nws yog inevitable ua rau tej yam kev puas tsuaj rau pwm raug.
2. Kub
Thaum ua cov khoom siv feem ntau (PP, PS, PVC, thiab lwm yam), pwm kub yog feem ntau 16-18 ℃. Nws yog tsim nyog hais tias qhov kub ntawm cov pwm yuav tsum tsis txhob qis dua 10 ℃. Condensation yuav cuam tshuam cov khoom zoo thiab ua rau xeb ntawm pwm. Lub riam ntug ntawm pwm yog ib feem tseem ceeb. Tus txheeb ze qhov kub thiab txias (± 5 ° C) ntawm sab sauv thiab qis pwm riam npoo tuaj yeem ua rau kev nthuav dav ntawm riam ntug (lub ntsiab lus ntawm thermal expansion thiab txias contraction) sib npaug. Txwv tsis pub, riam ntug yuav hnav los yog tawg vim tsis zoo khiav ntawm qhov incision.
Cov dej txias yuav tsum tau tshuaj xyuas txhua hnub thiab cov dej yuav tsum tau hloov tsis tu ncua. Yog tias cov pa phem loj heev, cov tshuaj ntxuav tes thiab cov kuab tshuaj yuav tsum tau ntxiv rau kev ntxuav kom tsis txhob thaiv cov pwm dej channel.
3. Lubrication
Daim ntawv qhia lub tes tsho ntawm cov kab qhia kev coj tus kheej yuav tsum tau lubricated ob zaug ib lub lim tiam; Cov pas nrig thiab ejector pas nrig yuav tsum tau lubricated txhua yim teev, thiab cov txiv ntoo yuav tsum tau kuaj xyuas kom xoob; Ntxuav cov pwm sab saud thiab qis nrog rab phom cua kom tsis txhob muaj pwm los ntawm kev puas tsuaj los ntawm cov khoom txawv teb chaws.
4. Cia
Ua ntej cia, tshem tawm cov dej txias uas seem hauv cov pwm dej channel nrog cua, thiab tom qab ntawd muab cov pwm tso rau hauv qhov chaw qhuav. Yog tias huab cua nyob hauv ib puag ncig siab, cov pwm saum npoo yuav tsum tau coated nrog Vaseline lossis txau nrog cov tshuaj tiv thaiv xeb rau kev tiv thaiv. Lub puab tsaig sab sauv thiab sab qis yuav tsum tau muab tso rau nyias kom deb li deb tau, thiab cov ejector pas nrig thiab cov pas nrig yuav tsum tau ntsug ntsug kom tiv thaiv pwm deformation. Yog hais tias tej yam kev mob tsis tso cai, ib tug ncaj board yuav tsum tau ntxiv nyob rau hauv nruab nrab ntawm lub riam ntug ntawm lub sab sauv thiab sab pwm kom tsis txhob muaj kev puas tsuaj rau riam ntug.
5. Kev siv thiab txij nkawm ntawm kub sib sau tuag yog ib qho kev ua haujlwm, uas yuav tsum muaj peev xwm thiab muaj kev paub txog.
Cov khoom tam sim no tau txais dav dav ntawm cov neeg siv khoom thiab muaj daim ntawv thov dav hauv kev ua lag luam.
