Ko te hononga matua i roto i te tukatuka kirihou. He maha ngā momo hua kirihou, ngā āhua wāhanga rānei e hiahiatia ana. E 30 ngā tikanga hanga, e whakawhirinaki ana ki te momo kirihou, te kōwhiringa mai i te āhua me te āhua me te rahi o te hua. Ko ngā tikanga tukatuka kirihou e whakamahia whānuitia ana ko te extrusion thermoplastic, te injection molding, te calendering, te pupuhi molding me te thermoforming. Ko te thermosetting plastic molding e whakamahia whānuitia ana i roto i te tukatuka kirihou e whakamahi ana hoki i te transfer molding, te injection molding, te laminate molding me te thermoforming. Hei tāpiri, kei reira ētahi tikanga pēnei i te maka me ngā monomers wai, ngā polymers rānei hei rauemi mata. I roto i ēnei tikanga, ko te extrusion me te injection molding te mea e whakamahia pinepinetia ana, ā, koinei hoki ngā tikanga tino taketake.
E whakamahia ana te konganuku me te rakau hei tukatuka i ngā kirihou. Nā te mea he rerekē ngā āhuatanga o ngā kirihou i ō te konganuku me te rakau, he ngoikore te kawe wera, he iti te tauwehenga o te whakawhānui wera, he iti te modulus o te ngāwari, he nui rawa te pēhanga ki ngā taputapu, ki ngā taputapu rānei, he ngāwari ki te hanga i te āhua rerekē, ā, he ngāwari te rewa o te wera tapahi. , ā, he ngāwari hoki te piri ki te taputapu. Nō reira, me urutau te miihini kirihou, ngā taputapu tapahi me ngā tere tapahi e rite ana ki ngā āhuatanga o ngā kirihou, ā, ko ētahi atu tikanga tukatuka noa ko te kani, te tapahi, te wero, te huri, te whakamahere, te keri, te huri, te whakakanapa, te tukatuka miro, me ētahi atu. Hei tāpiri, ka taea hoki te tapahi laser, te tā, me te whakarewa i ngā kirihou.
He tikanga whakarewa me te piri mō te tukatuka kirihou. Ko te whakarewa ko te whakamahi i te hau wera hei whakarewa i ngā hikohiko, te whakarewa rewa wera mā te whakamahi i te wera, me ngā tikanga whakarewa pēnei i te whakarewa auau teitei, te whakarewa waku, te whakarewa whakapūmau, te whakarewa ultrasonic me te whakarewa laser. Ka wehea ngā piripiri ki ngā whakarewa, ngā otinga kapia me ngā piripiri rewa wera.
Mā ngā tikanga here, whakarewa me ngā tikanga hononga ā-ringa ka taea te huihui i ngā wāhanga kirihou hei mahi hua tino pai.
