SMC Mould yog dab tsi

Compression pwm feem ntau siv hydraulic xovxwm tshuab thiab cov kab noj hniav thiab cov tub ntxhais yog tsau rau saum thiab hauv qab platens ntawm lub tshuab. Thaum cov khoom raug muab tso rau hauv lub pwm qhib, lub tshuab kaw, pwm tau rhuab, tom qab ntawd cov xovxwm quab yuam cov khoom ntws mus thoob plaws pwm. 

Nyob rau hauv cov txheej txheem saum toj no, cov khoom uas muab tso rau hauv qhib pwm yog feem ntau SMC, BMC, GMT thiab lwm yam khoom siv. Yog li peb ib txwm xa cov pwm no rau SMC pwm, BMC pwm, GMT pwm. 

Muaj qhov sib txawv ntawm SMC, BMC thiab GMT cov khoom. 

SMC (daim ntawv molding compounds) yog cov khoom siv fiber ntau siv thermoset feem ntau siv rau qhov loj qhov xav tau ntau zog. 

BMC (Bulk molding compounds) Nws yog tus cwj pwm los ntawm nws qhov kev ntxhib los mos thiab luv fiber ntau. 

GMT (Cov iav matreinforced thermoplastic) kuj tuaj yeem rov ua dua. 

Tsuas yog GMT cov khoom yuav tsum tau preheated.

Hloov cov cua txias hauv kev txhaj tshuaj pwm, SMC pwm xav tau cua sov channel. Cov cua kub ib txwm yog chav, roj, hluav taws xob lossis dej siab siab. 
Kev ua haujlwm kub ntawm SMC pwm feem ntau yog 140 degree txog 160 degree. Thaum tsim cov txheej txheem termprature nws yog ib qho tseem ceeb uas yuav tsum tau ua kom lub ntsej muag ntawm cov pwm tsis pub dhau qhov kub. Lub pwm uas muaj qhov kub tsis sib xws yuav ua kom yooj yim dua thiab tsim cov khoom nrog tsawg dua warpage, improved dimension stability thiab ib tug uniform deg tsos.
