Zeziphi iingenelo zokusebenzisa amasango amancinane kwizitofu zokungunda?

Ubume kunye nobukhulu bamasango ngaphakathiisitofu sokungundazinempembelelo enkulu kumgangatho wamalungu eplastiki, ngoko ke sidla ngokusebenzisa amasango amancinane kwizitofu zokungunda.

1) Amasango amancinci anokunyusa izinga lokuhamba kwezinto. Kukho umehluko omkhulu woxinzelelo phakathi kweziphelo ezimbini zesango elincinci, elinokunciphisa i-viscosity ebonakalayo ye-melt kwaye yenza kube lula ukuzalisa isikhunta.

2) Isango elincinci linokunyusa izinga lokushisa lokunyibilika kunye nokwandisa umbane. Ukuxhathisa ukukhuhlana kwisango elincinci kukhulu, xa inyibilika idlula esangweni, inxalenye yamandla iguqulwa ibe ngubushushu bokukhuhla kunye nokufudumala, okulungileyo ekuphuculeni umgangatho wamacandelo eplastiki abhityileyo okanye amacandelo eplastiki aneepateni ezintle. .

3) Amasango amancinci anokulawula kunye nokunciphisa ixesha lokuzaliswa, ukunciphisa uxinzelelo lwangaphakathi lweengxenye zeplastiki kunye nokunciphisa umjikelezo wokubumba. Kwi-injection, isiteji sokubamba uxinzelelo siyaqhubeka kuze kube yilapho i-condensation esangweni. Isango elincinci lidibanisa ngokukhawuleza kwaye ixesha lokuzaliswa lifutshane, elinciphisa ukuqhelaniswa kwe-condensation kunye ne-condensation strain ye-macromolecule kwaye inciphisa kakhulu uxinzelelo lwangaphakathi lokuzaliswa. Ukulungelelaniswa kwamasango amancinci ukuvalwa kunokulawula ngokuchanekileyo ixesha lokuzalisa kunye nokuphucula umgangatho weengxenye zeplastiki.

I-4) Isango elincinci linokulinganisela izinga lokutya kwendawo nganye. Kuphela emva kokuba umjelo wokuhamba ugcwele kwaye unoxinzelelo olwaneleyo, i-cavities inokuzaliswa ngexesha elifanayo, elinokuphucula ukungalingani kwesantya sokutya somgodi ngamnye.

5) Kulula ukucheba iinxalenye zeplastiki. Amasango amancinci anokususwa ngokukhawuleza ngesandla. Amasango amancinci ashiya amancinci amancinci emva kokususwa, okunciphisa ixesha lokunciphisa. Nangona kunjalo, isango elincinci kakhulu liya kwandisa kakhulu ukuchasana nokuhamba kunye nokwandisa ixesha lokuzalisa i-mold. Ukunyibilika kunye ne-viscosity ephezulu kunye ne-melt enefuthe elincinci le-shear rate kwi-viscosity ebonakalayo akufanele isetyenziswe.
