Moulded lossis txhaj? Qhov zoo thiab qhov tsis zoo ntawm cov txheej txheem roj hmab foob molding
Moulding machines (compression molding) thiab cov tshuab txhaj tshuaj (txhaj tshuaj molding) yog ob txheej txheem molding feem ntau siv los tsim cov khoom siv roj hmab. Txhua tus ntawm lawv muaj qhov tshwj xeeb zoo thiab qhov tsis zoo thiab tsim nyog rau kev tsim cov khoom siv roj hmab sib txawv. Cov hauv qab no yuav ua kom muaj kev sib piv cov ntsiab lus ntawm cov txheej txheem ntws, kev tsim khoom, cov khoom zoo, tus nqi, thiab lwm yam, thiab muab cov ntaub ntawv cuam tshuam.
Txheej txheem
Compression molding
Compression moldingyog muab cov roj hmab sib xyaw ua ntej hnyav rau hauv cov pwm pwm, siv lub siab thiab kub los ntawm lub phaj vulcanizing tshuab, ua cov roj hmab ntws hauv pwm thiab sau cov kab noj hniav, thiab tom qab qee lub sij hawm ntawm vulcanization cov tshuaj tiv thaiv, tsim cov khoom siv roj hmab. ntawm cov duab uas xav tau. Cov txheej txheem no yog tsim rau cov khoom uas muaj cov duab yooj yim thiab loj, xws li gaskets, sealing rings, thiab lwm yam.
Txhaj tshuaj molding
Kev txhaj tshuaj molding yog xa cov roj hmab sib xyaw rau hauv lub rhaub dej kub ntawm lub tshuab txhaj tshuaj los ntawm cov khoom siv pub mis, thiab tom qab cov khoom siv roj hmab tau rhuab thiab plasticized hauv lub thoob, cov khoom siv roj hmab yaj tau nrawm nrawm rau hauv cov pwm kaw los ntawm qhov siab- kev txiav txim siab ntawm cov ntsia hlau los yog plunger, thiab cov khoom yog tsim los ntawm vulcanization. Cov txheej txheem no yog tsim rau cov khoom uas muaj cov duab complex thiab siab qhov tseeb qhov yuav tsum tau, xws li cov ntsaws ruaj ruaj, poob siab-absorbing pads, thiab lwm yam.
Productivity
Compression molding
Lub voj voog ntawm compression molding yog qhov ntev, nrog rau cov kauj ruam ntawm kev tso cov roj hmab sib xyaw, clamping pwm, cua sov thiab vulcanizing, qhib pwm, thiab noj cov khoom. Lub sijhawm ntawm txhua lub voj voog nyob ntawm qhov tuab thiab qhov nyuaj ntawm cov khoom thiab feem ntau yog nyob ntawm ob peb feeb mus rau kaum feeb. Yog li ntawd, compression molding yog tsim nyog rau tsawg-ntim ntau lawm.
Txhaj tshuaj molding
Txhaj tshuaj molding muaj kev ua haujlwm siab. Vim hais tias cov roj hmab tau raug rhuab thiab plasticized ua ntej txhaj tshuaj, lub sij hawm txhaj rau hauv pwm kab noj hniav tsuas yog 1 ~ 5 vib nas this, thiab lub sij hawm vulcanization tseem luv dua. Yog li ntawd, qhov ua tau zoo ntawm kev txhaj tshuaj molding yog 4 ~ 7 npaug siab dua li ntawm compression molding, uas yog tsim rau ntau lawm.
Khoom Zoo
Compression molding
Qhov zoo ntawm cov khoom molded nyob ntawm qhov fluidity ntawm lub compound thiab cov pwm tsim. Vim lub sijhawm luv luv ntawm cov roj hmab hauv cov pwm, nws yog ib qho yooj yim los tsim npuas, suav nrog, thiab lwm yam tsis xws luag, uas cuam tshuam rau lub compactness thiab mechanical zog ntawm cov khoom. Tsis tas li ntawd, qhov tseeb qhov tseeb ntawm cov khoom compression-molded yog qhov tsawg, thiab tom qab txiav yuav tsum tau txiav.
Txhaj tshuaj molding
Cov khoom txhaj tshuaj molded yog cov khoom zoo. Vim tias cov roj hmab sau cov pwm kab noj hniav nyob rau hauv qhov siab, nws tuaj yeem tsim cov ntsiab lus nyuaj, qhov tseeb ntawm cov khoom yog siab, thiab cov khoom tiav yog qhov zoo. Nyob rau tib lub sijhawm, cov khoom siv txhaj tshuaj molded muaj cov compactness siab, zoo heev mechanical zog, thiab tsis tshua muaj flash, uas txo cov kev ua hauj lwm hnav khaub ncaws.
Nqi
Compression molding
Tus nqi ntawm cov khoom siv thiab cov pwm rau compression molding yog qhov tsawg, uas yog tsim rau cov khoom me me thiab ntau ntau yam. Txawm li cas los xij, vim qhov kev ua haujlwm tsawg, tus nqi zog ua haujlwm siab, thiab cov khoom yuav tsum tau kho tom qab, uas ua rau cov nqi ntau lawm.
Txhaj tshuaj molding
Tus nqi ntawm cov khoom siv thiab cov pwm rau kev txhaj tshuaj molding yog siab, tshwj xeeb tshaj yog cov qauv ntawm cov pwm thiab cov nqi tsim khoom siab. Txawm li cas los xij, vim qhov kev ua haujlwm siab ntau lawm, tus nqi ntawm ib qho khoom lag luam tsawg, uas yog tsim rau kev tsim khoom loj. Tsis tas li ntawd, kev txhaj tshuaj molding txo qhov flash, txuag roj hmab, thiab txo cov nqi khoom siv.
Scope ntawm daim ntawv thov
Compression molding
Nws yog qhov tsim nyog rau cov khoom uas muaj cov duab yooj yim thiab qhov loj me, lossis ntau lub sijhawm nrog cov khoom me me. Piv txwv li, gaskets loj, cov khoom tuab-walled, thiab lwm yam.
Txhaj tshuaj molding
Nws yog tsim rau cov khoom uas muaj cov duab nyuaj, siab qhov tseeb qhov yuav tsum tau muaj, thiab cov khoom loj. Piv txwv li, complex seals, shock-absorbing pads, khau khau, thiab lwm yam.
Raws li cov ntaub ntawv tseem ceeb, kev ua haujlwm ntawm kev txhaj tshuaj molding yog 4 ~ 7 npaug siab dua li ntawm compression molding, lub zog noj yog txo los ntawm 10%, thiab qhov tsim nyog tus nqi thiab qhov tseeb ntawm cov khoom kuj tseem txhim kho. Tsis tas li ntawd, cov khoom txhaj tshuaj molded muaj tsawg flash, uas txuag roj hmab thiab txo cov nqi khoom.
Compression molding thiab txhaj tshuaj molding muaj lawv qhov zoo thiab qhov tsis zoo, thiab kev xaiv cov txheej txheem molding tsim nyog yuav tsum tau ua tiav raws li cov duab, qhov loj me, batch, kev xav tau zoo, thiab lwm yam ntawm cov khoom. Rau cov khoom uas muaj cov duab yooj yim thiab cov khoom me me, compression molding muaj qhov zoo ntawm cov nqi qis thiab cov khoom siv yooj yim; Rau cov khoom uas muaj cov duab nyuaj thiab cov khoom loj, kev txhaj tshuaj molding muaj qhov zoo ntawm kev ua haujlwm siab thiab cov khoom zoo.
