Lub tswv yim ntawm pwm thiab molding yog qhov nrov heev hauv kev lag luam yas.Yas muaj cov yam ntxwv zoo xws li siab malleability, pheej yig tus nqi, siab stability.Yog li nws yog siv pervasively hauv molding.Yeej, Yas txhaj tshuaj molding yog cov txheej txheem tseem ceeb rau kev tsim cov khoom yas.Los rau lub tswv yim ntawm molding, nws yog ib tug txheej txheem ntawm manufacturing los ntawm cov kua los yog pliable cov khoom tshiab tau ib tug nruj zoo hu ua pwm.Hauv cov ntsiab lus yooj yim, yas molding yog txheej txheem uas cov yas molded rau hauv cov duab uas xav tau.
Txhaj tshuaj molding muaj kev koom tes zoo hauv kev tsim ntau yam khoom siv hauv tsev thiab kev lag luam.Nws yog siv los tsim ntau yam khoom siv xws li hluav taws xob vaj tsev, ntim, lub raj mis, lub tsheb sab hauv, combs, thiab lwm yam khoom yas feem ntau muaj niaj hnub no.Cov yam ntxwv zoo li kev ua siab ntev ntev, rov ua dua, xaiv cov khoom loj, tus nqi zog qis, qhov tsawg kawg nkaus poob, thiab qhov xav tau me ntsis kom tiav qhov chaw tom qab molding yog qhov zoo ntawm kev txhaj tshuaj molding.
Cov yas txhaj tshuaj pwm feem ntau yuav tsum tau ua raws li hauv cov txheej txheem ntawm cov yas txhaj tshuaj molding-
1. kev txhaj tshuaj molding tshuab2.raw khoom yas 3.Ib pwm.
Rau kev tsim cov yas txhaj tshuaj, muaj ntau yam khoom siv raw xws li thermosetting yas, elastomers thiab thermoplastic polymers (resins) thiab lwm yam yog siv rau kev tsim cov yas txhaj tshuaj vim cov ntaub ntawv no muaj viscosity ntau dua.Cov tshuab txhaj tshuaj yas muaj cov khoom siv hauv paus xws li cov khoom siv hopper, cua sov chav tsev, plunger thiab lwm yam. Cov yas yog yaj hauv lub tshuab txhaj tshuaj molding thiab tom qab ntawd txhaj rau hauv pwm, qhov twg nws txias thiab khov rau hauv qhov kawg.
