Dab tsi yog cov yas compression molding pwm?
Cov khoom siv pwm uas siv los ua cov pwm no tsuas yog siv los ua ib hom pwm rau cov thermosetting yas, thiab nws cov khoom siv coj los sib xyaw ua ke yog kev siv tshuab.
Compression molding txoj kev yog raws li cov yam ntxwv ntawm cov pwm yas yog kub rau molding qhov kub (feem ntau hauv 103 ~ 180 ℃), thiab tom qab ntawd ntsuas cov hmoov txhuam mould rau hauv cov pwm kab thiab cov chaw thau khoom, kaw pwm, yas nyob rau hauv tshav kub thiab siab yog softening nplaum ntws, tom qab ib lub sijhawm ua tiav qhov kev kho tiav, tsim cov qauv ntawm cov khoom lag luam.Cov molding thiab compression molding lwm chav nruab nrog cais them nyiaj, ua pwm ua ntej kaw, nplaum nplaum ntws hauv kev kho vaj tse tiav sab hauv kev noj haus preheating , lub siab nyob rau hauv qhov kev txiav txim siab ntawm kev kub ceev extrusion pwm kab noj hniav, hardening ntawm cov duab.Hauv pwm siv yog siv rau molding qee thermoplastic plastics tshwj xeeb xws li nyuaj rau molten thermoplastic (ptfe) dawb paug (txias pressing molding) thiab siab kho qhov muag ntawm cov cob lo ntsiab muag, me me foaming cellulose nitrate lub tsheb kauj log, etc.Qhov die - casting pwm yog tsim los ntawm kab noj hniav, pub chamber, taw qhia mechanism, ejection ib feem thiab cua sov qhov system.Cov khoom ua moulds yog dav siv encapsulate hluav taws xob components.The cov khoom siv nyob rau hauv lub chaw ua khoom ntawm qhov kev tuag yog yeej tib yam li cov tshuaj pwm.
