1. Ob txoj kev txhaj tshuaj molding tshuab muaj ob qhov qauv ntawm cov qauv thiab specifications. Lub nozzle yuav tsum nyob rau hauv ib tug tshwj xeeb qauv raws li lub hom ntau hom, los yog ob lub nrog nrog tib qauv yuav rotated thiab transposed. Thaum muab cov tshuaj tiv thaiv, nws yuav tsum muaj qhov kub, tshuaj txhaj, txhaj tshuaj thiab lwm yam khoom siv tsis zoo ntawm ob qho tib si ntawm plasticizing txhaj tshuaj yuav tsum yog tib yam, thiaj li txo lub fluctuation ntawm cov cuab yeej tsis nyob hauv ob qhov khoom ntawm cov khoom siv.
2. Piv nrog rau cov khoom siv yas txhaj tshuaj zoo tib yam, kev txhaj tshuaj tiv thaiv thiab kev txhaj tshuaj yuav tsum yog qhov tseem ceeb ntawm qhov tseem ceeb. Lub ntsiab yog vim tias cov pwm khiav hauv ob chav xim txhaj tshuaj molding ntev dua, cov qauv nyuab dua, thiab lub zog tsis kam ntawm kev txhaj tshuaj ntau dua.
3. Qhov ob xim xim molded cov khoom yas yuav tsum yog cov ntaub ntawv raw nrog thermal stability thiab tsis tshua yaj viscosity, thiaj li kom tsis txhob kub siab ntawm cov khoom siv melting thiab lub sij hawm ntev nyob hauv tus neeg khiav dej num. Polyolefin resin, polystyrene thiab ABS yog siv dav hauv plastics.
