Cov khoom siv yas yog tsim los ntawm kev sib xyaw ntawm cov khoom siv hluavtaws thiab ntau yam khoom siv ntxiv raws li cov khoom siv raw, siv kev txhaj tshuaj, extrusion, nias, nchuav thiab lwm yam.Thaum cov khoom yas raug molded, lawv kuj tau txais qhov kev ua tau zoo kawg, yog li yas molding yog cov txheej txheem tseem ceeb ntawm kev tsim khoom.
1. Kev txhaj tshuaj molding tseem hu ua kev txhaj tshuaj molding.Nws yog ib txoj hauv kev siv lub tshuab txhaj tshuaj sai sai txhaj cov yas molten rau hauv pwm thiab ua kom ruaj khov kom tau txais ntau yam khoom yas.
2. Cov txheej txheem extrusion molding yog txheej txheem uas siv cov kev sib hloov ntawm cov ntsia hlau thiab siab mus txuas ntxiv cov yas yas rau hauv pwm, thiab thaum dhau los ntawm qee qhov zoo ntawm cov tuag, cov yas profile tsim nyog rau cov duab ntawm cov tuag tau txais.
3. Compression molding, tseem hu ua compression molding, compression molding, compression molding, thiab lwm yam, yog ntxiv cov khoom pellets los yog prefabricated pieces rau hauv pwm, thiab siv cua sov thiab siab kom soften thiab yaj lawv, thiab nyob rau hauv lub siab Txoj kev filling. pwm kab noj hniav kom tau cov khoom yas tom qab kho.
4. Tshuab moulding (raws li cov txheej txheem thib ob ntawm cov yas) yog ib txoj hauv kev uas cov yas hollow parisons tau tshuab thiab deformed los ntawm compressed cua, thiab cov khoom yas tau txais tom qab txias thiab shaping.
5. Lub casting ntawm yas zoo ib yam li cov hlau casting.Ntawd yog, cov khoom siv polymer lossis cov khoom siv monomer nyob rau hauv lub xeev ntws yog txhaj rau hauv cov pwm tshwj xeeb, thiab nyob rau hauv qee qhov xwm txheej, nws yog reacted, solidified, thiab tsim rau hauv cov txheej txheem ntawm cov khoom yas raws li cov pwm kab noj hniav.
6.Gas-pab txhaj molding (hu ua gas-pab molding) yog ib txoj hauv kev tshiab hauv kev ua cov yas.Muab faib ua hollow forming, short shot, and full shot.
