E mano tini ngā kirihou kei te mākete mō te hanga tauira tere, te hanga iti rānei – he uaua te whiriwhiri i te kirihou tika mō tētahi kaupapa, inā koa mō ngā kaihanga auaha, mō ngā kaipakihi rānei. He rerekētanga te utu, te kaha, te ngāwari me te whakaotinga o te mata o ia rauemi. Me whakaaro ehara i te mea ko te whakamahinga o te wāhanga, o te hua rānei anake, engari ko te taiao hoki e whakamahia ai.
I te nuinga o te wā, kua whakapai ake ngā āhuatanga miihini o ngā kirihou hangarau, ā, he roa ake te mau, kāore hoki e rerekē i te wā e hangaia ana. Ka taea hoki te whakarerekē i ētahi momo kirihou hei whakapai ake i tō rātou kaha, me te ātete ki te pānga me te wera. Me ruku tātou ki ngā rauemi kirihou rerekē hei whakaaro i runga i te mahi a te wāhanga whakamutunga, te hua rānei.
Ko tētahi o ngā kapia e whakamahia whānuitia ana hei hanga wāhanga mīhini ko te nairona, e mōhiotia ana ko te polyamide (PA). Ina konatunatua te polyamide ki te molybdenum, he maeneene te mata mō te nekeneke ngāwari. Heoi, kāore i te tūtohutia kia whakamahia ngā taputapu nairona-ki-te-airona nā te mea, pērā i ngā kirihou, ka piri tahi. He ātete nui te PA ki te pakaru me te pakū, ā, he pai ngā āhuatanga mīhini i ngā pāmahana teitei. He rauemi pai te nairona mō te tā 3D me te kirihou, engari ka mimiti i te wai i roto i te wā.
He kōwhiringa pai rawa atu hoki te Polyoxymethylene (POM) mō ngā wāhanga mīhini. Ko te POM he kapia acetal e whakamahia ana hei hanga i te DuPont's Delrin, he kirihou utu nui e whakamahia ana i roto i ngā taputapu, ngā tīwiri, ngā wira me ētahi atu. He kaha te piko me te kaha kume, te pakari me te mārō o te POM. Heoi, ka pakaru te POM i te kawakore, te haurehu me te wai wera, ā, he uaua ki te piri tahi.
Mena he momo ipu tō kaupapa, ko te polypropylene (PP) te whiringa pai rawa atu. Ka whakamahia te polypropylene ki ngā ipu rokiroki kai nā te mea he ātete ki te wera, he ātete ki ngā hinu me ngā whakarewa, ā, kāore e tuku matū, kia haumaru ai te kai. He pai hoki te taurite o te pakari me te kaha pānga o te polypropylene, kia māmā ai te hanga koropiko ka taea te piko tonu me te kore e whati. Ka taea hoki te whakamahi ki ngā paipa me ngā ngongo.
Ko tētahi atu kōwhiringa ko te polyethylene (PE). Ko te PE te kirihou tino noa o te ao, he iti te kaha, te pakeke, me te pūmau. He kirihou mā te miraka e whakamahia ana hei hanga pounamu rongoā, ipu miraka me te hopi horoi. He tino ātete te polyethylene ki te whānuitanga o ngā matū engari he iti te ira rewa.
He mea tino pai te rauemi Acrylonitrile butadiene styrene (ABS) mō ngā kaupapa katoa e hiahia ana kia kaha te ātete ki te pānga me te kaha ki te haehae me te pakaru. He mama te ABS, ā, ka taea te whakapakari ki te muka karāhe. He nui ake te utu i te styrene, engari he roa ake te mau o te mahi nā tōna pakeke me tōna kaha. He tauira 3D ABS kua whakakikoruatia mō te hanga tauira tere.
I runga i ōna āhuatanga, he kōwhiringa pai te ABS mō ngā taputapu mau. I Star Rapid, i hangaia e mātou te pouaka mataarataki mā E3design mā te whakamahi i te kirihou ABS/PC pango kua pania ki te werohanga. Mā tēnei kōwhiringa rauemi ka māmā ake te taputapu katoa, me te whakarato hoki i tētahi pouaka ka taea te tu atu i ngā ru i ētahi wā, pērā i te wā e pā ana te mataarataki ki tētahi mata pakeke. He kōwhiringa pai te polystyrene pānga teitei (HIPS) mēnā e hiahia ana koe ki tētahi rauemi maha-whakamahinga me te ātete pānga. He pai tēnei rauemi mō te hanga pouaka taputapu hiko pakari me ngā pouaka taputapu. Ahakoa he utu iti te HIPS, kāore i te kiia he hoa taiao.
He maha ngā kaupapa e hiahia ana ki ngā kapia whakakoi werohanga he ngāwari pērā i te rapa. He kōwhiringa pai te polyurethane thermoplastic (TPU) nā te mea he maha ngā hanganga motuhake mō te ngāwari teitei, te mahi pāmahana iti me te roa. Ka whakamahia hoki te TPU i roto i ngā taputapu hiko, ngā roera, te whakamarumaru taura, me ngā taonga hākinakina. Nā tōna ātete whakarewa, he kaha te TPU ki te pakū me te kutikuti, ā, ka taea te whakamahi i roto i ngā taiao ahumahi maha. Heoi, e mōhiotia ana mō te mimiti i te makuku mai i te hau, e uaua ai te tukatuka i te wā whakaputa. Mō te whakakoi werohanga, kei reira te rapa thermoplastic (TPR), he iti te utu, he ngāwari hoki te whakahaere, pērā i te hanga i ngā kakau rapa mimiti-ru.
Mena e hiahiatia ana he karaihe mārama, he matapihi rānei mō tō wāhanga, ko te kiriaku (PMMA) te mea pai rawa atu. Nā tōna pakari me tōna ātete ki te pakū, ka whakamahia tēnei rauemi hei hanga matapihi ātete pakaru pērā i te plexiglass. He pai te whakakanapa o te PMMA, he kaha te kume, ā, he iti te utu mō te whakaputa nui. Heoi, kāore i te rite te ātete ki te pānga, ki te matū rānei ki te polycarbonate (PC).
Mena he rauemi kaha ake tāu kaupapa, he kaha ake te PC i te PMMA, ā, he tino pai ngā āhuatanga whatu, he mea pai mō ngā karaihe me ngā matapihi ātete-matā. Ka taea hoki te piko me te hanga i te PC i te pāmahana rūma me te kore e pakaru. He mea whai hua tēnei mō te hanga tauira nā te mea kāore e hiahiatia he taputapu pokepoke utu nui hei hanga. He nui ake te utu o te PC i te kiriaku, ā, mā te roa o te wā e noho ana ki te wai wera ka taea te tuku i ngā matū kino, nō reira kāore e tutuki i ngā paerewa haumaru kai. Nā tōna ātete ki te pānga me te rakuraku, he pai te PC mō ngā momo tono. I Star Rapid, ka whakamahia e mātou tēnei rauemi hei hanga whare mō ngā pito ringaringa o Muller Commercial Solutions. I mīhinihia te wāhanga ki te CNC mai i tētahi poraka PC totoka; nā te mea me tino mārama, i orohia ki te ringaringa, ā, i whakakanapahia ki te mamaoa.
He tirohanga poto noa iho tēnei mō ētahi o ngā kirihou e whakamahia whānuitia ana i roto i te hanga. Ko te nuinga o ēnei ka taea te whakarerekē ki ngā muka karāhe rerekē, ki ngā whakaū UV, ki ngā hinu whakahinuhinu, ki ētahi atu kapia rānei hei whakatutuki i ētahi whakaritenga.
Ko Gordon Stiles te kaiwhakaū me te perehitini o Star Rapid, he kamupene hanga tauira tere, taputapu tere me te iti te rahinga. I runga i tana wheako hangarau, i whakatūria e Stiles a Star Rapid i te tau 2005, ā, i raro i tana kaiārahi kua tipu te kamupene ki te 250 ngā kaimahi. He rōpū miihini me ngā tohunga hangarau o te ao a Star Rapid e whakakotahi ana i ngā hangarau matatau pēnei i te tā 3D me te miihini CNC maha-tuaka me ngā tikanga hanga tuku iho me ngā paerewa kounga teitei. I mua i tana whakaurunga ki Star Rapid, nā Styles te STYLES RPD, te kamupene hanga tauira tere me te taputapu nui rawa atu o te UK, i hokona ki ARRK Europe i te tau 2000.
