Ukungunda kwePlastiki sisishunqulelo somngundo odityanisiweyo osetyenziselwa ukubumba ucinezelo, ukubumba i-extrusion, inaliti, ukubumba ukuvuthela kunye nokubumba okuphantsi kwamagwebu.Utshintsho olulungelelanisiweyo lwe-mold convex kunye ne-concave molds kunye nenkqubo encedisayo yokubumba inokuqhuba uluhlu lwamacandelo eplastiki yeemilo ezahlukeneyo kunye nobukhulu obahlukeneyo.Iimbumba zeplastiki ngumama weshishini, kwaye ukukhutshwa kwemveliso entsha ngoku kubandakanya iiplastiki.

Ibandakanya ubukhulu becala ukungunda kwabasetyhini kunye nomgodi oguquguqukayo owenziwe ngumbumba obhinqileyo odityanisiweyo, icandelo lokungunda labasetyhini kunye nebhodi yekhadi edityanisiweyo yabasetyhini, kunye ne-convex mold substrate edityanisiweyo, icandelo le-convex mold, ibhodi yekhadi edityanisiweyo. icandelo lokusika i-cavity kunye ne-Punch ene-variable core eyenziwe ngamacwecwe ahlangeneyo e-side-cut.
Ukuze kuphuculwe ukusebenza kweeplastiki, izinto ezahlukeneyo ezincedisayo, ezifana nokuzaliswa, iiplastiki, i-lubricant, i-stabilizers, i-colorants, njl., kufuneka zongezwe kwi-polymer ukuze zibe yiplastiki kunye nokusebenza kakuhle.

1. I-Synthetic resin iyona nto ibaluleke kakhulu kwiiplastiki, kwaye umxholo wayo kwiiplastiki ngokuqhelekileyo ngu-40% ukuya kwi-100%.Ngenxa yokuba umxholo mkhulu, kwaye ubume be-resin buhlala bumisela ubunjani beplastiki, abantu bahlala bethatha i-resin njengesithethantonye seplastiki.Ngokomzekelo, bhidanisa i-polyvinyl chloride resin kunye neeplastiki ze-polyvinyl chloride, kunye ne-phenolic resins kunye neeplastiki ze-phenolic.Enyanisweni, i-resin kunye neplastiki ziingcamango ezimbini ezahlukeneyo.I-resin yipolymer ekrwada engekalungiswa engasetyenziswanga kuphela ukwenza iiplastiki, kodwa iphinde ibe yimathiriyeli ekrwada yokwaleka, izinto zokuncamathelisa, kunye neentsinga zokwenziwa.Ukongeza kwinxalenye encinci yeplastiki equkethe i-resin ye-100%, iiplastiki ezininzi zifuna ezinye izinto ngaphezu kweyona nto iphambili ye-resin.

2. I-Filler Filler ikwabizwa ngokuba yi-filler, enokuphucula amandla kunye nokumelana nokushisa kweeplastiki kunye nokunciphisa iindleko.Ngokomzekelo, ukongezwa komgubo womthi kwi-phenolic resin kunokunciphisa kakhulu iindleko, okwenza iplastiki ye-phenolic ibe yenye yeeplastiki ezingabizi kakhulu, ngelixa iphucula kakhulu amandla oomatshini.Izihluzi zinokohlulwa zibe ziindidi ezimbini: izihluzi zendalo kunye nezihluzi ze-inorganic, eyokuqala efana nomgubo womthi, amalaphu, iphepha kunye nemicu eyahlukahlukeneyo yelaphu, kunye neyokugqibela efana nefiber yeglasi, umhlaba wediatomaceous, iasbestos, kunye nekhabhoni emnyama.

3. IiPlastiki Iiplastiki zePlastiki zinokunyusa iplastiki kunye nokuguquguquka kweeplastiki, ukunciphisa i-brittleness, kunye nokwenza iiplastiki zibe lula ukusetyenzwa kunye nokumila.IiPlastiki zidla ngokuba ziikhompawundi eziphezulu zokubilisa eziphilayo ezixubeneyo nentlaka, ezingenatyhefu, ezingenavumba, kwaye zizinzile ekukhanyeni nasekufudumaleni.Ezona zisetyenziswa kakhulu zi-phthalate esters.Ngokomzekelo, ekuveliseni iiplastiki ze-polyvinyl chloride, ukuba iiplastiki ezininzi zongezwa, iiplastiki ezithambileyo ze-polyvinyl chloride zinokufumaneka;ukuba akukho okanye ngaphantsi kwe-plasticizers ezongeziweyo (ixabiso <10%), iiplastiki ze-polyvinyl chloride eziqinileyo zinokufumaneka.

4. I-Stabilizer Ukuze uthintele i-resin yokwenziwa ukuba ingachithwa kwaye yonakaliswe ngokukhanya kunye nokushisa ngexesha lokucubungula kunye nokusetyenziswa, kunye nokwandisa ubomi benkonzo, i-stabilizer kufuneka ifakwe kwiplastiki.Ngokuqhelekileyo zisetyenziselwa i-stearate kunye ne-epoxy resin.

5. I-Colourants Colorants inokwenza iiplastiki zibe nemibala eyahlukeneyo eqaqambileyo kunye nenhle.Idla ngokusetyenziswa iidayi eziphilayo kunye ne-inorganic pigments njengemibala.

6. I-Lubricant Indima ye-lubricant kukuthintela iplastiki ukuba ibambelele kwi-mold yensimbi ngexesha lokubumba, kwaye kwangaxeshanye yenza ubuso beplastiki bube bushelelezi kwaye bubuhle.Izithambisi ezisetyenziswa ngokuqhelekileyo ziquka i-stearic acid kunye ne-calcium kunye neetyuwa ze-magnesium.Ukongeza kwizongezo ezingentla, i-flame retardants, i-foaming agents, i-antistatic agents, njl.
