Kev Tshawb Fwm Mould los ntawm cov khoom yuav tsum muaj cov thermal conductivity thiab txaus txiav ntug txiav ntug zog. Tam sim no txhuas 70/75 yog cov khoom ntawm feem ntau ntawm cov pwm nrog cov kev sib raug zoo heev. Raws li kev ua haujlwm ntawm cov hlau zoo, cov pwm kab noj hniav feem ntau yog machined. Po copper alloy pwm kuj muaj cua kub tsis txaus thiab zoo corrosion kuj. Txawm li cas los, nws tus nqi siab, kim, thiab vim nws qhov hnyav peb zaug rau txhuas, tej zaum yuav loj dua nyob rau hauv lub tshuab mould. Po hlau hlau alloy yooj yim siv vuam los yog kho mosaic kho.
Tshaj ntawm molds Thaum cov khoom Puab Mould, lub pwm yuav tsum tau vented thiaj li cia cov roj mus khiav sai sai. Qhov ntau tshaj thiab kev siv qis qis yog qhov pa npau npau. Deep sandblasting los yog kev ntxhib los mos kev kho ntawm cov pwm kab noj hniav tseem tuaj yeem pab rau pa. Lwm qhov tseem ceeb rau kev qaug zog (rau cov qhov chaw uas yas yuav tsum tau muab pov rau hauv qhov chaw nruj nruj) yog qhia cov ntsiab lus.
Extrusion Tshuab Pwm Muaj cov yeeb yam hauv qab no.
(1) extrusion Tshuab Pwm, ntxiv rau cov khoom siv ob-phab ntsa thiab lwm yam pwm tshwj xeeb, tsuas yog cov kab tsis zoo pwm, tsis txhob muab txiv neej pwm.Compared nrog lwm cov khoom yas siv hauv pwm, tus qauv yog ntau yooj yim.
(2) vim hais tias cov txheej txheem pwm tsis yog ib tug txiv neej pwm, koj tuaj yeem inflate lub mold siv nrog kev nyuab siab, kev zoo ntawm cov khoom yas.
(3) pwm kab noj hniav tsis muaj kev sib tw, khiav mus rau hauv pwm thiab ces kaw pwm. Parison yaj kom vam khom cov cua ntawm huab cua kom tawg kom tiav cov kab noj hniav.
(4) Piv nrog rau kev pwm, extrusion Tshuab Pwm Cov kab noj hniav tsis tshua muaj siab, siv cov khoom tsim pwm, kab noj hniav uas tsis muaj kev sib zog kho. Pwm cov nqi qis dua.
(5) tuaj yeem ua tau ntau yam ntxiv, muaj kev ua haujlwm siab, koj tuaj yeem tsim cov khoom loj;
(6) tuaj yeem tsim cov khoom sib txawv ntawm qhov kev sib tshuam;
(8) Lub taub hau thiab cov granulator muaj peev xwm muab granulated nrog granulation ntawm extruder thiab granulator,
(9) me me hneev taw, me me kom huv si.
