Cov khoom tseem ceeb rau molding ntau lawm yog hydraulic xovxwm.Lub luag haujlwm ntawm hydraulic xovxwm tshuab nyob rau hauv cov txheej txheem nias yog siv lub siab rau cov yas los ntawm pwm, qhib pwm thiab eject cov khoom.
Compression molding yog tsuas yog siv rau molding ntawm thermosetting yas.Rau cov thermoplastics, vim qhov xav tau los npaj qhov khoob ua ntej, nws yuav tsum tau ua kom sov thiab txias ua ke, yog li lub voj voog ntau lawm ntev, qhov kev ua tau zoo yog tsawg, thiab kev siv lub zog loj.Tsis tas li ntawd, cov khoom uas muaj cov duab complex thiab ntau qhov tseeb tsis tuaj yeem nias.Li no qhov kev sib txawv ntawm kev lag luam ntau dua kev txhaj tshuaj molding.
Covcompression molding tshuab(nias rau luv) siv rau molding yog hydraulic xovxwm.Nws lub peev xwm nias tau qhia hauv nominal tonnage, feem ntau, muaj 40t ﹑ 630t ﹑ 100t ﹑ 160t ﹑ 200t ﹑ 250t ﹑ 400t ﹑ 500t series ntawm presses.Muaj ntau tshaj 1,000 tons ntawm ntau txheej xovxwm.Cov ntsiab lus tseem ceeb ntawm cov xovxwm tshwj xeeb muaj xws li kev khiav hauj lwm tonnage, ejection tonnage, platen loj rau kho qhov tuag, thiab strokes ntawm kev khiav hauj lwm piston thiab ejection piston, thiab lwm yam. Feem ntau, lub sab sauv thiab qis templates ntawm cov xovxwm yog nruab nrog cua sov thiab cua txias. .Cov khoom me me tuaj yeem siv cov xovxwm txias (tsis muaj cua sov, tsuas yog dej txias xwb) rau shaping thiab txias.Siv cov cua kub xovxwm tshwj xeeb rau thermal plasticization, uas tuaj yeem txuag hluav taws xob.
Raws li cov degree ntawm automation, presses yuav muab faib ua tes presses, semi-automatic presses, thiab siab tsis siv neeg presses.Raws li tus naj npawb ntawm cov khaubncaws sab nraud povtseg ntawm lub tiaj tiaj, nws tuaj yeem muab faib ua ob txheej txheej thiab ntau txheej xovxwm.
Hydraulic xovxwm yog lub tshuab siab uas siv los ntawm hydraulic kis.Thaum nias, cov yas yog thawj zaug ntxiv rau qhov qhib pwm.Tom qab ntawd pub cov roj siab rau lub tog raj kheej ua haujlwm.Coj los ntawm kem, lub piston thiab cov nqaj txav tau txav mus rau hauv qab (los yog nce siab) kom kaw cov pwm.Thaum kawg, lub zog tsim los ntawm hydraulic xovxwm yog kis mus rau pwm thiab ua rau cov yas.
Cov yas hauv pwm melts thiab softens nyob rau hauv qhov kev txiav txim ntawm tshav kub.Cov pwm tau ntim nrog lub siab los ntawm hydraulic xovxwm thiab muaj tshuaj lom neeg cov tshuaj tiv thaiv.Txhawm rau tso tawm cov dej noo thiab lwm yam volatiles uas ua rau lub sij hawm condensation cov tshuaj tiv thaiv ntawm plastics thiab xyuas kom meej cov khoom zoo, nws yog ib qhov tsim nyog los ua kom lub siab nyem thiab tso pa tawm.Tam sim ntawd txhawb thiab tswj.Lub sijhawm no, cov resin hauv cov yas txuas ntxiv mus rau cov tshuaj tiv thaiv.Tom qab ib lub sij hawm ntawm lub sij hawm, ib qho insoluble thiab infusible nyuaj lub xeev yog tsim, thiab lub solidification molding tiav.Cov pwm qhib tam sim ntawd, thiab cov khoom raug tshem tawm ntawm pwm.Tom qab cov pwm raug ntxuav lawm, qhov kev tsim khoom tom ntej tuaj yeem ua tiav.
Nws tuaj yeem pom los ntawm cov txheej txheem saum toj no tias qhov kub thiab txias, siab, thiab lub sijhawm yog qhov tseem ceeb rau compression molding.Txhawm rau txhim kho kev tsim khoom ntawm lub tshuab thiab kev nyab xeeb thiab kev ntseeg tau ntawm kev ua haujlwm, kev khiav hauj lwm ceev ntawm lub tshuab kuj yog ib qho tseem ceeb uas tsis tuaj yeem tsis quav ntsej.Yog li ntawd, cov yas hydraulic xovxwm siv rau kev nias yuav tsum muaj peev xwm ua tau raws li cov hauv qab no:
① Lub siab nias yuav tsum txaus thiab kho tau, thiab nws tseem yuav tsum ncav cuag thiab tuav lub siab ua ntej nyob rau hauv ib lub sijhawm.
② Cov nqaj txav tau ntawm cov xovxwm hydraulic tuaj yeem nres thiab rov qab los ntawm txhua qhov chaw hauv lub cev.Qhov no yog qhov tsim nyog heev thaum txhim kho pwm, nias ua ntej, batch them, lossis tsis ua haujlwm.
③ Cov nqaj txav tau ntawm cov xovxwm hydraulic tuaj yeem tswj tau qhov nrawm thiab siv lub zog ua haujlwm ntawm txhua qhov chaw hauv lub cev.Ua kom tau raws li qhov yuav tsum tau ua ntawm pwm ntawm qhov siab sib txawv.
Cov nqaj txav tau ntawm hydraulic xovxwm yuav tsum muaj qhov nrawm nrawm hauv qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoobThaum tus txiv neej pwm kov cov yas, pwm kaw ceev yuav tsum tau qeeb.Txwv tsis pub, cov pwm los yog ntxig yuav raug puas los yog cov hmoov yuav raug ntxuav tawm ntawm tus poj niam pwm.Nyob rau tib lub sijhawm, kev ua kom qeeb qeeb kuj tuaj yeem tshem tawm tag nrho cov huab cua hauv pwm.
