1.Ukugqitywa koYilo kunye nokwenza iMold: Ngaphambi kokuba isinyithi sinyibilike, uyilo lwemedali kufuneka luguqulwe lube yimold ebonakalayo—eli lelona nyathelo libalulekileyo lokuqinisekisa ukuchaneka. Ilogo yomthengi, umbhalo, okanye umsebenzi wobugcisa (umz., imascot yemarathon, uphawu lwenkampani) ifakwa kwidijithali kwaye iguqulwe ibe yimodeli ye-3D kusetyenziswa isoftware ye-CAD. Iinjineli zilungisa uyilo ukuze ziqwalasele "ukuncipha" (isinyithi siyancipha kancinci njengoko sipholile) kwaye zongeza izinto ezincinci ezifana "nee-angles zedraft" (imiphetho etyibilikileyo) ukunceda ukukhupha i-casting blank kwimold ngokulula. Ukwenziwa kweMold, Imodeli ye-3D isetyenziselwa umatshini imold yentsimbi (ehlala yenziwe ngentsimbi ye-H13 eshushu esebenza ngayo, emelana nobushushu obuphezulu kunye noxinzelelo). Imold ineziqingatha ezibini: enye eneenkcukacha "ezilungileyo" (eziphakanyisiweyo) zemedali, kwaye enye ine-cavity "engalunganga" (ebuyiselweyo). Kwiimedali ezimacala mabini, zombini iziqingatha zemold ziya kuba nemingxuma eneenkcukacha. Uvavanyo lweMold, Imold yovavanyo ingasetyenziselwa kuqala ukujonga ukuba uyilo ludlula ngokucacileyo na—oku kuthintela ukuchitha isinyithi kwimveliso epheleleyo engalunganga.

2.Ukukhethwa kwezinto kunye nokunyibilika, Iimedali ezidityaniswe nge-die zisebenzisa kakhulu "iimetali ezingenayo i-ferrous" (iimetali ezingenayo i-iron) kuba ziyanyibilika kumaqondo obushushu aphantsi kwaye zigeleza kakuhle ziye kwiimolds. Ezona zikhethwayo ziqhelekileyo zezi: I-Zinc Alloy: Eyona ndlela idumileyo—ixabiso eliphantsi, ilula, kwaye kulula ukuyiphosa. Inomphezulu ogudileyo othatha i-plating (umz., igolide, isilivere) kakuhle, okwenza kube kuhle ukungena kwiimedali eziphakathi. I-Brass Alloy: Ukhetho oluphezulu—lunokukhanya okufudumeleyo, kwesinyithi (akukho mfuneko ye-plating enzima) kunye nokuqina okungcono. Ihlala isetyenziswa kwiimbasa zeprimiyamu (umz., iimedali zempumelelo yobomi bonke). I-Aluminium Alloy: Ayifumaneki kwiimedali (ilula kakhulu ukuba "ivakale" kakhulu) kodwa isetyenziswa ngamanye amaxesha kwiimedali ezinkulu, ezinohlahlo-lwabiwo mali. Isinyithi sinyibilikiswa kwisithando somlilo kumaqondo obushushu aphakathi kwe-"380°C (zinc)" kunye ne-"900°C (ithusi)" ide ibe lulwelo. Emva koko iyahluzwa ukuze kususwe ukungcola (njengokungcola okanye i-oxide) okunokonakalisa umphezulu wemedali.

3.Ukuphosa ngeDie (Inqanaba "lokubumba")Kulapho isinyithi siba yimbasa engenambasa. Ukulungiswa kweMold: Iinxalenye ezimbini zemold yentsimbi zibotshelelwa ndawonye kumatshini wokuphosa i-die (nokuba "yigumbi elishushu" le-zinc, elinyibilika ngokukhawuleza, okanye "yigumbi elibandayo" le-bronze/aluminium, elifuna ubushushu obuphezulu). Imold ikwatshizwa nge-agent yokukhulula (ioyile ekhaphukhaphu) ukuthintela isinyithi esinyibilikisiweyo ukuba singanamatheli. I-Metal Injection: I-piston okanye i-plunger ityhala isinyithi esinyibilikisiweyo kwindawo yemold ngoxinzelelo oluphezulu kakhulu (2,000–15,000 psi). Olu xinzelelo luqinisekisa ukuba isinyithi sizalisa zonke iinkcukacha ezincinci zemold—nokuba zincinci okanye imigca emincinci yokukhulula. Ukupholisa kunye nokuSusa: Isinyithi siyaphola imizuzwana eli-10–30 (kuxhomekeke kubukhulu) ide iqine. Imold emva koko iyavuleka, kwaye i-ejector pin encinci ityhala i-casting blank ngaphandle. Kweli nqanaba, i-blank isene "flash" (isinyithi esincinci, esigqithisileyo esijikeleze imiphetho) ukusuka apho iinxalenye zemold zidibana khona.

4.Ukucheba nokuGqiba (Ukucoca isithuba). Ukususa iimbumbulu/Ukusika: Ifleshi isuswa kusetyenziswa umatshini wokucheba (kwiiodolo ezinkulu) okanye izixhobo zesandla (kwiibhetshi ezincinci). Eli nyathelo liqinisekisa ukuba imiphetho yemedali igudile kwaye ilingana—akukho mabala abukhali okanye arhabaxa. Ukusila nokuPolisha: Indawo engenanto igqunywa ngesanti yesanti ecolekileyo ukuze igudise naziphi na iziphene zomphezulu (umz., amaqamza amancinci avela kwi-casting). Ukuze igqitywe ngokukhazimla, ipolisha ngevili lokubutha kunye ne-polisha compound (umz., i-rouge ukuze kukhanye okufana nesipili).

5.Ukuhombisa Umphezulu (Ukwenza Imbasa "I-Pop")Kulapho imbasa ifumana khona umbala wayo, ubunjani bayo, kunye nophawu lwayo—iindlela eziqhelekileyo zonyango ziquka:

Ukuplata: Isithuba sintywiliswa kwibhafu ye-electrolytic ukuze kongezwe uqweqwe lwesinyithi (umz., igolide, isilivere, i-nickel, ithusi lakudala). Ukuplata kukhusela imbasa kumhlwa kwaye kuphucula inkangeleko yayo (umz., ukuplata kwethusi lakudala ukuze kubonakale ngathi yinto yakudala).

Ukuzaliswa kwe-enamel: Kwiimedali ezinemibala, i-enamel ethambileyo okanye eqinileyo ifakwa kwiindawo ezingenanto (kusetyenziswa isirinji okanye istencil). I-enamel ethambileyo yomiswa ngomoya kwaye inomphezulu othambileyo kancinci; i-enamel eqinileyo ibhakwa kwi-800°C ukwenza isiphelo esigudileyo, esifana neglasi.

Ukukrola/Ukuprinta: Iinkcukacha zobuqu (umz., amagama abamkeli, imihla yesiganeko) zongezwa ngokukrola nge-laser (ukuze zichaneke) okanye ngokuprinta ngesikrini sesilika (kwimibala engqindilili).

6.Ukuhlolwa koMgangatho kunye noKuhlanganisa

Ukuhlolwa koMgangatho: Imbasa nganye ihlolwa ukuba ayinazo iziphene—umz., iinkcukacha ezingekhoyo, iplati engalinganiyo, okanye amaqamza enamel. Naziphi na iziqwenga ezineziphene ziyaliwa okanye ziphinde zisetyenzwe.

Ukudibanisa (Ukuba Kuyafuneka): Ukuba imbasa inezixhobo (umz., iribhoni, ikliphu, okanye isitshixo), ezi zinto zincamathiselwa ngesandla okanye ngoomatshini. Umzekelo, iluphu yeribhoni idityaniswa ngasemva kwembasa ukuze kube lula ukuyinxiba.
