Ngaphezu koko, kufuneka zihlangabezane neemfuno zomthetho zengingqi ezifana ne-FDA's 21 CFR Part 820 e-United States kunye ne-EU's Medical Device Regulation (MDR). Le migangatho ilawula yonke into ukusuka kubunyulu bezinto kunye nokusebenza koomatshini ukuya kukuhambelana kokubulala iintsholongwane (ngesiqhelo i-gamma okanye i-ETO) kunye nokulebhelisha.

 

Isicwangciso se-Ansix Tech: Ukusuka kwiPrototype ukuya kwiMveliso eQinisekisiweyo

Ukuzibandakanya kwe-Ansix Tech kwaqala kwinqanaba lokuyila imveliso. Amava abo kushishino abavumele ukuba badibanise imigaqo ye-Design for Manufacturability (DFM) kwasekuqaleni, inyathelo elisebenzayo elithintela uyilo olutsha olubizayo kamva.

 

Uyilo lwePrototype kunye noQinisekiso: Besebenzisa iimodeli zeCAD zabathengi, iinjineli ze-Ansix zenze uHlalutyo olupheleleyo lweMold Flow (DFM). Le software yokulinganisa yaxela kwangaphambili indlela i-resin yeplastiki ekhethiweyo eya kuzalisa ngayo umngxuma wesikhunta, ichonga iingxaki ezinokubakho ezifana nemigca ye-weld (amanqaku abuthathaka apho i-fronts zeplastiki ezinyibilikisiweyo zidibana khona), imigibe yomoya, amanqaku esinki, kunye nokupholisa okungalinganiyo. Kwicandelo elinoxinzelelo olufana nebharele yesirinji, umgca we-weld kwindawo enoxinzelelo oluphezulu awamkelekanga. I-DFM yabavumela ukuba balungise iindawo zesango (apho iplastiki ingena khona umngxuma), ukufana kobukhulu bodonga, kunye noyilo lwembambo ye-plunger kudala ngaphambi kokuba intsimbi isikwe. Umngundo womzekeloEmva koko zakhiwa ukuvelisa iisampulu ezisebenzayo zokuqinisekisa uyilo, ukujonga ukuba zilingana na izixhobo zokujova, kunye novavanyo lokuqala lokuhambelana kwezinto eziphilayo.

 

Ukuqinisekiswa koMveliso kunye neSatifikethi seMveliso yoBuninzi: Utshintsho ukusuka kwiprototype ukuya kwimveliso yobuninzi yinkqubo evaliweyo. I-Ansix Tech yenze i-Full Installation Qualification (IQ), i-Operational Qualification (OQ), kunye ne-Performance Qualification (PQ). Oku kwakubandakanya:

 

IQ: Ukubhala phantsi ukuba oomatshini bokubumba kunye noomatshini bokubumba injection bafakwe ngokuchanekileyo.

Idla ngokuba nexabiso eliphantsi ngekhilogram kunePC.

 

Isigqibo Esiqhutywa Yixabiso se-Ansix Tech: Ngovavanyo oluqatha, iqela lifumanise ukuba i-resin ye-COC esemgangathweni wezonyango, ezinzileyo nge-gamma, nangona inexabiso eliphezulu lezinto eziluhlaza, inikezele ngeenzuzo ezibalulekileyo zenkqubo. Izinga layo eliphantsi lokuncipha livumele inkqubo yokubumba eqinileyo, eqikelelweyo enokunyamezelana okuqinileyo. Iimpawu zayo ezihambayo ezigqwesileyo zenze ukuba uyilo lwenkqubo yokubaleka ebandayo lusebenze kakuhle (ukunciphisa inkunkuma xa kuthelekiswa ne-hot runners yale nto) kunye namacandelo odonga anokubhitya ngelixa kugcinwa umlinganiselo woxinzelelo. Kulapho i-lever yokuqala enkulu yokunciphisa iindleko yatsalwa khona: Ukusebenza okuphezulu kwe-COC kwavumela ukwenza inxalenye ibe lula—ukusebenzisa izinto ezincinci kwisirinji ngaphandle kokubeka emngciphekweni ukhuseleko. Ngaphezulu kwezigidi zeeyunithi, olu phuculo lwezinto luguqulela ekugcinweni kwemali okuthe ngqo kumthengi.
