- .Winding molding txheej txheem yog qhwv lub nruam fiber ntau (los yog ntaub band, pre-immersed yarn) soaked nyob rau hauv cov resin kua nplaum raws li ib tug tej yam tsis tu ncua, thiab ces solidify thiab tshem tawm cov khoom.
- Txheej siab molding yog hais txog kev sib xyaw ntawm ntau txheej lossis cov khoom sib txawv hauv qab cua sov thiab siab. Feem ntau siv rau kev ua cov yas thiab roj hmab ua.
- Watering molding yog ib txoj kev ntawm kev ua cov yas. Thaum ntxov casting yog pom cov polymer rau hauv pwm rau hauv pwm nyob rau hauv ib txwm siab. Nyob rau xyoo 1960, cov nylon ib leeg casting pom kev txhim kho ntawm polyamide nrog kev tsim cov tshuab molding, cov ntsiab lus ntawm cov tsoos casting tau hloov. Cov tshuaj polymer, decentralized polyvinyl chloride muab tshuaj txhuam thiab yaj kuj tuaj yeem siv rau casting molding.
- Plasticity poob yog cov yam ntxwv ntawm kev siv cov khoom siv thermoplastic polymer, uas yog, nyob rau hauv qee qhov xwm txheej, nws muaj cov nplaum, thiab cov yam ntxwv ntawm cov khoom hauv lub xeev tuaj yeem rov qab los ntawm chav tsev kub. Nws yog zoo li tus qauv tsim raws li nws lub xeev nplaum, thiab tom qab ntawd solidified ntawm chav tsev kub.
- Txoj kev compression molding feem ntau yog siv rau kev tsim cov khoom siv yas thermosetry. Tom qab molding yog rhuab, nws melts, nias lub pwm, thiab ces solidified los ntawm cua sov.
