Ixabisa malini utyalo-mali ngekhilogram nganye? Lo mbuzo ufikela kuyo yonke idesika yobunjineli bokuthengwa kwempahla—phambi kwee-RFQs, ngexesha lophononongo lohlahlo lwabiwo-mali, ngakumbi xa kuthelekiswa ababoneleli abasuka elunxwemeni. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sicaphule kwiiprojekthi zotyalo-mali ze-1,200 ukususela ngo-2018. Siye sabona iingcaphuno ziguquka ukusuka kwi-$ 8.50 ukuya kwi-$ 47 / kg-kwaye kungekhona ngenxa yemidlalo yokuphawula. Umahluko uvela kwizinto ezine eziphathekayo: uhlobo lwe-alloy, inxalenye yobunzima, ubungakanani bebhetshi, kunye neemfuno zokugqiba. Esi sikhokelo sinqumla ingxolo. Ikunika isakhelo sexabiso lomgangatho wefektri-hayi imida yethiyori, kodwa yintoni eneneni ehambisa inaliti kwimveliso yokwenyani.
Ukukhetha i-alloy yi-#1 yeendleko zomqhubi-hayi iJometri
Iinjineli ezininzi zicinga iimilo ezintsonkothileyo zonyusa iindleko zotyalo-mali ngekhilogram nganye. Ayilunganga. Ingxubevange yongamele. Nantsi into esiyibona mihla le:
- Ingxubevange ye-cobalt-nickel (AMS 5387, T800) i-avareji yeedola ezingama-32–$47/kg - iqhutywa kukuguquguquka kwezinto ekrwada, ulawulo olungqongqo lwenyibiliko, kunye nonyango lobushushu lwasemva kokuphosa ukuzinzisa izigaba eziphambili zegamma.
- Iintsimbi ezingenastainless (CF8M, CF3M) emhlabeni kwi-$18–$26/kg — ngaphezulu kwentsimbi yekhabhoni ngenxa yomxholo wechromium/nickel kunye neefestile zekhemistri eziqinile
- I-Ductile iron (ASTM A) ibambe ngokuzinzileyo kwi-$9.50–$13.50/kg—indawo yokunyibilika ephantsi, ukushwabana okuncinci, inkqubo yeqokobhe elixolelayo
Sakhe sacaphula indlu yempompo ye-hydraulic kwi-T800 cobalt alloy kwi-41.20 ye-kg. Ijometri efanayo kwi-ASTM A351 CF8M yehle yaya kwi-$22.60/kg. Akukho tshintsho loyilo. Kuphela i-metallurgy. Ukuba inkcazo yakho ivumela ukutshintshwa kwezinto-nokuba kurhwebo oluncinci lwe-tensile-ufumana amandla kwangoko iindleko zotyalo-mali ngekhilogram nganye amaxabiso.
Imicimbi entsonkothileyo-kodwa kuphela emva kokuba imilinganiselo ebalulekileyo itshixiwe
“Ukuntsonkotha” akuthethi “ukuba nkulu”—ngaphandle kokuba kunyanzeliswa umsebenzi wezandla. Utyalo-mali lugqwesa kwiimilo zendalo, iipaseji zangaphakathi, kunye neendonga ezibhityileyo. Into eyongeza ixabiso ayilogophe okanye i-contour-ziimpawu ezaphula i-automation: ii-undercuts ezifuna ukudityaniswa kwe-wax ngesandla, imingxuma engaboniyo enzulu kuno-8× ububanzi, okanye umphezulu ogqityiweyo ucolekile kune-Ra 1.6 µm ngaphandle komatshini.
Kwi-odolo yamva nje yezindlu zepiston pump cylinder, umthengi uchaze ±0.05 mm ukunyamezela ukutyeba kodonga kwi-ID eyi-220 mm. Oko kubangele ukuskena okupheleleyo kweCMM kuyo yonke iqashiso-kunye neprimiyamu ye-14% ngaphezulu komgangatho ± 0.15 mm. Kodwa xa bekhulula ukunyamezela kwi-± 0.10 mm kwiindawo ezingavalwanga, iindleko zehla i-$ 2.30 / kg kunye neempembelelo zokusebenza zero. Umthetho wethu: chaza iidatum ezibalulekileyo kuqala. Emva koko vumela ukuphosa kubambe okuseleyo.
Umthamo utshintsha yonke into-Ingakumbi ngaphantsi kwama-500 amaqhekeza
Iindleko zotyalo-mali ngekhilogram nganye yehla kakhulu phakathi kwamaqhekeza angama-1-50 kunye namaqhekeza angama-500-2,000-kodwa iiplateaus emva koko. Ngoba? I-amortization yezixhobo. Isixhobo sepateni ye-wax yenxalenye ephakathi-complexity iqhuba i-$2,800–4,500 yeedola. Kwii-pcs ze-50, yi-$ 56- $ 90 eyongeziweyo kwiyunithi nganye. Kwi-1,000 pcs? Nje $2.80–4.50 $.
Silandelela oku ngokuchanekileyo. Ngomzimba wevalvu yentsimbi engenastainless (1.8 kg/unithi), ixabiso lethu lotyalo-mali olucatshulweyo ngekhilogram nganye yayi:
- I-$ 28.40 / kg kwii-pcs ze-50 (ibandakanya i-tooling epheleleyo + i-3-shell iterations)
- I-$21.90/kg kwi-500 pcs (isixhobo esihlanjululwe ngokupheleleyo, umjikelo wokomiswa kweqokobhe olungiselelwe)
- I-$ 20.30 / kg kwi-2,000 pcs (i-batch yokulayisha i-furnace ephuculweyo, isantya se-scrap phantsi ukuya kwi-2.1%)
Akukho umlingo. Ifiziksi nje, ulawulo lwenkqubo, kunye noseto oluphinda-phindayo.
Ukugqiba ayisiyiyo iKhetho-Kunexabiso ngomphezulu, hayi ngenxalenye
"I-As-cast" inqabile kwizicelo zemizi-mveliso. Uninzi lwabathengi badinga ubuncinci be-vibratory deburring kunye nokudutyulwa kokudubula. Kodwa inyathelo ngalinye elongezelelweyo lixabisa ngokulandelelanayo:
- I-Vibratory deburr + i-alumina blast: + $ 0.85/kg
- Electropolish (Ra ≤ 0.4 µm): +$4.20/kg
- Passivation (ASTM A967 Nitric): + $1.10/kg
- Ukusila okulinganayo kokutywinwa kobuso: +$6.90/kg (kulinganiswa ngobuso, hayi ngenxalenye)
Kutshanje siphinde salungisa i-cobalt alloy nozzle order apho umxhasi wacela i-electropolish *kunye* nokusila kwendawo kwizitulo ezibini ezincinci ze-orifice. Ukugqitywa kwedwa kwongezelela i-$ 11.30 / kg-ngaphezulu kweendleko zokulahla isiseko salo bakala le-alloy. Isifundo: Cacisa kuphela oko kutywinwa, izilayidi, okanye amaqabane. Tsiba izinto zokuhombisa ngaphandle kokuba ukuxhathisa umhlwa okanye ukulinganisa ukuhamba kuyabafuna.
Ukufumana Amaxabiso Okwenyani Kuqala Ngomzobo Wakho-Hayi Uhlahlo-lwabiwo-mali Lwakho
Iingcaphuno eziqhelekileyo azinamsebenzi. Ixabiso lokwenyani lotyalo-mali lotyalo-mali ngekhilogram nganye yexabiso lomzi-mveliso lifuna ii-callouts ze-GD&T, ii-certs zemathiriyeli (AMS, ASTM, EN), kunye namanqaku okugqiba—hayi nje “intsimbi engenastainless, umgangatho olungileyo.” Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY, iqela lethu lokucaphula liphonononga yonke imizobo yokwenziwa phambi kokucaphula. Sifaka imingcipheko emingciphekweni: ukugqwetheka kobushushu kwiingalo ezinde ezibhityileyo, ukuqhekeka kweqokobhe kwirediya yangaphakathi ebukhali, okanye imiba yokukhupha iwax kwiipokotho ezinzulu. Olo hlaziyo luthatha iiyure ezingama-48-kwaye lugcina iiveki kamva.
Ukuba uvavanya ababoneleli, cela ireyithi yenkunkuma eqhelekileyo kwiklasi yakho yealloy, inkqubo yabo yeqokobhe ihlala amaxesha, nokuba ingaba ngabanini balebhu yabo yeceramic slurry. Ezo nkcukacha ziqikelela ukuhambelana ngcono kunalo naliphi na iphepha lexabiso. Kwaye khumbula: esona sicatshulwa sisezantsi sihlala sifihla iindleko zokusebenza kwakhona, ukulibaziseka kokuhlolwa, okanye ukukhukuliseka okuphakathi kwiibhetshi.
Ukuchaneka, kuyenzeka iindleko zotyalo-mali ngekhilogram nganye uqikelelo-olusekelwe kwidatha yenkqubo yokwenyani, hayi i-spreadsheets-qala ngomzobo oqinisekisiweyo kunye nezinto eziqinisekisiweyo. Okuseleyo kulandela.
