Txhaj Mould Rau Asmeskas

Kev txhaj tshuaj molding yog siv los tsim ntau yam xws li hlau spools, ntim khoom, lub kaus mom lub raj mis, cov khoom siv tsheb thiab cov khoom ua si, cov khoom ua si, hnab tshos, qee cov khoom siv suab paj nruag (thiab qhov chaw ntawm lawv), ib lub rooj zaum thiab cov rooj me me, cov thawv ntim khoom, cov khoom siv kho tshuab. qhov chaw (nrog rau cov iav), thiab feem ntau lwm yam khoom yas muaj hnub no. Txhaj tshuaj molding yog cov txheej txheem niaj hnub tshaj plaws ntawm kev tsim cov khoom yas; nws yog qhov zoo tagnrho rau kev tsim cov ntim siab ntawm tib yam khoom.
Thaum cov thermoplastics yog molded, feem ntau pelletised raw khoom yog pub los ntawm lub hopper rau hauv ib lub rhuab chim chim nrog ib tug reciprocating ntsia hlau. Thaum nkag mus rau hauv lub thoob, qhov kub thiab txias nce ntxiv thiab Van der Waals rog uas tiv thaiv cov txheeb ze ntawm cov saw hlau tsis muaj zog vim yog qhov chaw ntawm cov molecules ntau dua thermal zog xeev.
