I-mold yeplastiki sisifinyezo se-mold edibeneyo esetyenziselwa ukubumba ngokucinezela, ukubumba okuphumayo, ukujova, ukubumba ngokuvuthela kunye nokubumba okuphantsi kwe-foam. Utshintsho oludibeneyo lwe-mold convex kunye ne-concave mold kunye ne-assistant molding system lunokucubungula uthotho lweendawo zeplastiki ezineemilo ezahlukeneyo kunye nobukhulu obahlukeneyo. I-mold yeplastiki ngumama weshishini, kwaye ukukhutshwa kwemveliso entsha ngoku kubandakanya iiplastiki.

Iquka ikakhulu i-mold yabasetyhini ene-variable cavity eyenziwe yi-female mold combined substrate, i-female mold component kunye ne-female mold card combined card, kunye ne-convex mold combined substrate, i-convex mold component, i-men mold combined card board, i-cavity cutting component kunye ne-A punch ene-variable core eyenziwe yi-side-cut composite plates.
Ukuze kuphuculwe ukusebenza kweeplastiki, kufuneka kongezwe izixhobo ezahlukeneyo ezincedisayo, ezinje ngezizalisi, iiplastiki, izinto zokuthambisa, izinto ezizinzisayo, izinto ezifaka imibala, njl.njl., kwipolymer ukuze zibe ziiplastiki ezisebenza kakuhle.

1. I-synthetic resin yeyona nto ibalulekileyo kwiplastiki, kwaye umxholo wayo kwiiplastiki ngokubanzi uphakathi kwama-40% ukuya kwi-100%. Ngenxa yokuba umxholo mkhulu, kwaye uhlobo lwe-resin luhlala lumisela uhlobo lweplastiki, abantu badla ngokujonga i-resin njengento efanayo neplastiki. Umzekelo, dibanisa i-polyvinyl chloride resin neeplastiki ze-polyvinyl chloride, kunye ne-phenolic resin neeplastiki ze-phenolic. Enyanisweni, i-resin kunye neplastiki ziingcamango ezimbini ezahlukeneyo. I-Resin yi-polymer eluhlaza engalungiswanga engasetyenziswanga kuphela ukwenza iiplastiki, kodwa ikwasetyenziselwa izinto ezikrwada zokugquma, izincamathelisi, kunye neefayibha zokwenziwa. Ukongeza kwinxalenye encinci kakhulu yeplastiki equlethe i-100% resin, uninzi lweplastiki lufuna ezinye izinto ukongeza kwi-resin yecandelo eliphambili.

2. I-Filler Filler ikwabizwa ngokuba yi-filler, enokuphucula amandla kunye nokumelana nobushushu beplastiki kwaye inciphise iindleko. Umzekelo, ukongezwa komgubo womthi kwi-phenolic resin kunokunciphisa kakhulu iindleko, okwenza iplastiki ye-phenolic ibe yenye yeplastiki ezingabizi kakhulu, ngelixa ikwaphucula kakhulu amandla oomatshini. I-Fillers inokwahlulwa ibe ziintlobo ezimbini: i-organic fillers kunye ne-inorganic fillers, yokuqala efana nomgubo womthi, amalaphu, iphepha kunye neefayibha ezahlukeneyo zelaphu, kwaye yokugqibela efana ne-glass fiber, i-diatomaceous earth, i-asbestos, kunye ne-carbon black.

3. Iiplastiki Iiplastiki zinokunyusa ukuqina kunye nokuguquguquka kweeplastiki, zinciphise ukuqhekeka, kwaye zenze kube lula ukuzicubungula nokuzibumba iiplastiki. Iiplastiki zihlala ziyimichiza ye-organic ebilayo kakhulu exutywa ne-resin, engenatyhefu, engenavumba, kwaye izinzile ekukhanyeni nasekufudumaleni. Ezona zisetyenziswa kakhulu zii-esters ze-phthalate. Umzekelo, kwimveliso yeeplastiki ze-polyvinyl chloride, ukuba kongezwa iiplastiki ezingaphezulu, iiplastiki ze-polyvinyl chloride ezithambileyo zinokufunyanwa; ukuba kongezwanga iiplastiki okanye ngaphantsi (ubungakanani obungaphantsi kwe-10%), kungafunyanwa iiplastiki ze-polyvinyl chloride eziqinileyo.

4. Isiqinisi Ukuze kuthintelwe ukuba i-resin yokwenziwa ingaboli kwaye yonakaliswe kukukhanya nobushushu ngexesha lokucubungula nokusetyenziswa, kwaye kwandiswe ubomi benkonzo, kufuneka kongezwe isiqinisi kwiplastiki. Ezisetyenziswa kakhulu yi-stearate kunye ne-epoxy resin.

5. Izinto zokufaka imibala Izinto zokufaka imibala zingenza iiplastiki zibe nemibala eyahlukeneyo eqaqambileyo nemhle. Iidayi zendalo kunye nemibala engaphiliyo esetyenziswa rhoqo njengezinto zokufaka imibala.

6. Isithambisi Indima yesithambisi kukuthintela iplastiki ukuba inamathele kwisikhunta sesinyithi ngexesha lokubumba, kwaye kwangaxeshanye yenze umphezulu weplastiki ube mpuluswa kwaye ube mhle. Izithambisi ezisetyenziswa rhoqo ziquka i-stearic acid kunye ne-calcium kunye ne-magnesium salts zayo. Ukongeza kwezi zithambisi zingasentla, izithinteli zomlilo, ii-foam agents, ii-antistatic agents, njl.njl. zinokongezwa kwiplastiki.
