Kev suav nqi ntawmcov ntawv hlau qhov chawyog hloov pauv thiab nyob ntawm cov duab kos tshwj xeeb. Nws tsis yog txoj cai tsis hloov pauv. Koj yuav tsum nkag siab txog ntau txoj hauv kev ua cov khoom hlau. Feem ntau hais lus, tus nqi ntawm cov khoom = tus nqi khoom siv + tus nqi ua tiav + (tus nqi kho qhov chaw) + ntau yam se + cov txiaj ntsig. Yog tias cov hlau ntawv xav tau pwm, cov nqi pwm yuav raug ntxiv.
Tus nqi pwm (kwv yees tus naj npawb tsawg kawg nkaus ntawm cov chaw nres tsheb uas xav tau rau kev pwm raws li txoj kev tsim cov hlau ntawv, 1 chaw nres tsheb = 1 pawg pwm)
1. Hauv pwm, cov khoom siv sib txawv ntawm cov khoom siv raug xaiv raws li lub hom phiaj ntawm pwm: qhov loj ntawm lub tshuab ua haujlwm, qhov ntau ntawm kev ua haujlwm, qhov yuav tsum tau ua kom raug, thiab lwm yam;
2. Cov ntaub ntawv (raws li tus nqi teev tseg, xyuam xim seb nws puas yog hom hlau tshwj xeeb thiab seb nws puas xav tau xa tuaj);
3. Kev Thauj Khoom (cov nqi thauj khoom loj);
4. Se;
5. 15~20% tus nqi tswj hwm thiab cov nyiaj tau los ntawm kev muag khoom;
Tus nqi tag nrho ntawm cov khoom siv hlau ua feem ntau yog = tus nqi khoom siv + tus nqi ua tiav + cov khoom txheem ruaj khov + kho kom zoo nkauj saum npoo + cov nyiaj tau los, tus nqi tswj hwm + tus nqi se.
Thaum ua cov khoom me me yam tsis siv pwm, feem ntau peb xam qhov hnyav ntawm cov khoom siv * (1.2 ~ 1.3) = qhov hnyav tag nrho, thiab xam tus nqi khoom siv raws li qhov hnyav tag nrho * tus nqi ntawm cov khoom siv; tus nqi ua tiav = (1 ~ 1.5) * tus nqi khoom siv; tus nqi kho kom zoo nkauj electroplating Feem ntau, lawv raug xam raws li qhov hnyav tag nrho ntawm cov khoom. Ib kilogram ntawm cov khoom raug nqi ntau npaum li cas? Ib square meter ntawm kev txau raug nqi ntau npaum li cas? Piv txwv li, nickel plating yog xam raws li 8 ~ 10 / kg, tus nqi khoom siv + tus nqi ua tiav + tus qauv ruaj khov. Cov khoom + kho kom zoo nkauj nto = tus nqi, qhov nyiaj tau los feem ntau tuaj yeem xaiv ua tus nqi * (15% ~ 20%); tus nqi se = (tus nqi + qhov nyiaj tau los, tus nqi tswj hwm) * 0.17. Muaj ib daim ntawv ceeb toom ntawm qhov kev kwv yees no: tus nqi khoom siv yuav tsum tsis suav nrog se.
Thaum kev tsim khoom loj xav tau siv cov pwm, feem ntau cov lus hais yuav muab faib ua cov lus hais pwm thiab cov lus hais qhov chaw. Yog tias siv pwm, tus nqi ua cov khoom yuav qis dua, thiab tag nrho cov nyiaj tau los yuav tsum tau lees paub los ntawm qhov ntau lawm. Tus nqi ntawm cov khoom siv raw hauv peb lub Hoobkas feem ntau yog cov khoom siv tag nrho rho tawm tus nqi siv cov khoom siv. Vim tias yuav muaj teeb meem nrog cov khoom seem uas tsis tuaj yeem siv thaum lub sijhawm ua kom dawb paug ntawmkev tsim cov ntawv hlauQee yam ntawm lawv siv tau tam sim no, tab sis qee yam tsuas yog muag tau ua khoom pov tseg xwb.
Kev tsim cov ntawv hlau Cov qauv nqi ntawm cov khoom hlau feem ntau yog muab faib ua cov ntu hauv qab no:
1. Tus nqi khoom siv
Tus nqi khoom siv yog hais txog tus nqi khoom siv raws li qhov yuav tsum tau kos duab = qhov ntim khoom * qhov ceev ntawm cov khoom siv * tus nqi ntawm cov khoom siv.
2. Tus nqi khoom txheem
Hais txog tus nqi ntawm cov khoom txheem uas cov duab kos xav tau.
3. Cov nqi ua haujlwm
Hais txog cov nqi ua haujlwm uas yuav tsum tau ua rau txhua txoj haujlwm uas yuav tsum tau ua kom tiav cov khoom. Yog xav paub ntxiv txog cov txheej txheem ntawm txhua txoj haujlwm, thov saib "Hom Ntawv Sau Nqi" thiab "Cov Lus Qhia Txog Cov Nqi ntawm Txhua Txoj Haujlwm". Cov khoom tseem ceeb ntawm cov nqi ua haujlwm tam sim no tau teev tseg rau kev piav qhia.
1) CNC blanking
Nws cov nqi sib xyaw = kev poob nqi thiab kev txo nqi ntawm cov khoom siv + tus nqi ua haujlwm + cov khoom siv pabcuam thiab cov khoom siv poob nqi thiab kev txo nqi:
Kev poob nqi ntawm cov khoom siv yog xam raws li 5 xyoos, thiab txhua xyoo raug kaw ua 12 lub hlis, 22 hnub hauv ib hlis, thiab 8 teev hauv ib hnub.
Piv txwv li: rau 2 lab yuan ntawm cov khoom siv, cov khoom siv poob nqi ib teev = 200 * 10000 / 5 / 12 / 22 / 8 = 189.4 yuan / teev
Tus nqi ua haujlwm:
Txhua lub CNC xav tau 3 tus kws kho tshuab los ua haujlwm. Cov nyiaj hli nruab nrab ntawm txhua tus kws kho tshuab yog 1,800 yuan. Lawv ua haujlwm 22 hnub hauv ib hlis, 8 teev hauv ib hnub, uas yog, tus nqi ib teev = 1,800 * 3/22/8 = 31 yuan / teev. Tus nqi ntawm cov khoom siv pabcuam: hais txog Cov khoom siv pabcuam tsim khoom xws li cov roj nplua nyeem thiab cov kua dej uas xav tau rau kev ua haujlwm ntawm cov khoom siv raug nqi kwv yees li 1,000 yuan ib hlis rau txhua daim khoom siv. Raws li 22 hnub hauv ib hlis thiab 8 teev hauv ib hnub, tus nqi ib teev = 1,000 / 22/8 = 5.68 yuan / teev.
1) Khoov
Nws cov nqi sib xyaw = kev poob nqi thiab kev txo nqi ntawm cov khoom siv + tus nqi ua haujlwm + cov khoom siv pabcuam thiab cov khoom siv poob nqi thiab kev txo nqi:
Kev poob nqi ntawm cov khoom siv yog xam raws li 5 xyoos, thiab txhua xyoo raug kaw ua 12 lub hlis, 22 hnub hauv ib hlis, thiab 8 teev hauv ib hnub.
Piv txwv li: rau cov khoom siv uas muaj nqis RMB 500,000, cov khoom siv poob nqi ib feeb = 50 * 10000 / 5 / 12 / 22 / 8 / 60 = 0.79 yuan / feeb. Feem ntau nws siv sijhawm 10 vib nas this txog 100 vib nas this los khoov ib qho khoov, yog li cov khoom siv poob nqi ib qho cuab yeej khoov. = 0.13-1.3 yuan / riam. Tus nqi ua haujlwm:
Txhua yam khoom siv yuav tsum muaj ib tus kws kho tshuab los ua haujlwm. Cov nyiaj hli nruab nrab ntawm txhua tus kws kho tshuab yog 1,800 yuan. Nws ua haujlwm 22 hnub hauv ib hlis, 8 teev hauv ib hnub, uas yog, tus nqi ib feeb yog 1,800/22/8/60 = 0.17 yuan/feeb, thiab tus nqi nruab nrab ib feeb yog 1,800 yuan/hli. Nws tuaj yeem ua tau 1-2 qhov khoov, yog li: tus nqi ua haujlwm ib qho khoov = 0.08-0.17 yuan/riam tus nqi ntawm cov khoom siv pabcuam:
Tus nqi txhua hli ntawm cov khoom siv pabcuam rau txhua lub tshuab khoov yog 600 yuan. Raws li 22 hnub hauv ib hlis thiab 8 teev hauv ib hnub, tus nqi ib teev = 600/22/8/60 = 0.06 yuan / riam
1) Kev kho qhov chaw
Cov nqi txau sab nraud yog suav nrog tus nqi yuav khoom (xws li electroplating, oxidation):
Tus nqi txau = tus nqi khoom siv hmoov + tus nqi ua haujlwm + tus nqi khoom siv pabcuam + kev poob nqi khoom siv
Tus nqi siv hmoov: Feem ntau, tus nqi suav yog raws li square meters. Tus nqi ntawm txhua kilogram ntawm hmoov yog li ntawm 25-60 yuan (feem ntau yog raws li cov neeg siv khoom xav tau). Txhua kilogram ntawm hmoov feem ntau tuaj yeem tsuag tau 4-5 square meters. Tus nqi siv hmoov = 6-15 yuan/square meter
Tus nqi ua haujlwm: Muaj 15 tus neeg nyob hauv kab txau tshuaj, txhua tus neeg raug them 1,200 yuan / hli, 22 hnub hauv ib hlis, 8 teev hauv ib hnub, thiab tuaj yeem txau 30 square meters ib teev. Tus nqi ua haujlwm = 15 * 1200/22/8/30 = 3.4 yuan / square meter
Tus nqi khoom siv pabcuam: feem ntau yog hais txog tus nqi ntawm cov kua ua ntej kho thiab roj siv hauv qhov cub kho. Nws yog 50,000 yuan ib hlis. Nws yog raws li 22 hnub hauv ib hlis, 8 teev hauv ib hnub, thiab txau 30 square meters ib teev.
Tus nqi khoom siv pabcuam = 9.47 yuan / square meter
Kev txo nqi ntawm cov khoom siv: Kev nqis peev rau hauv kab tsuag yog 1 lab, thiab kev txo nqi yog raws li 5 xyoos. Nws yog lub Kaum Ob Hlis txhua xyoo, 22 hnub hauv ib hlis, 8 teev hauv ib hnub, thiab tsuag 30 square meters ib teev. Tus nqi txo nqi ntawm cov khoom siv = 100 * 10000 / 5 / 12 / 22 / 8 / 30 = 3.16 yuan / square meter. Tag nrho cov nqi tsuag = 22-32 yuan / square meter. Yog tias xav tau kev tiv thaiv ib nrab, tus nqi yuav siab dua.
4.Tus nqi ntim khoom
Nyob ntawm cov khoom, qhov yuav tsum tau ntim khoom sib txawv thiab tus nqi sib txawv, feem ntau yog 20-30 yuan / cubic meter.
5. Cov nqi tswj kev thauj mus los
Cov nqi xa khoom raug suav rau hauv cov khoom.
6. Cov nuj nqis tswj hwm
Cov nuj nqis tswj hwm muaj ob ntu: nqi xauj tsev Hoobkas, dej thiab hluav taws xob thiab cov nuj nqis nyiaj txiag. Nqi xauj tsev Hoobkas, dej thiab hluav taws xob:
Tus nqi xauj tsev rau dej thiab hluav taws xob txhua hli yog 150,000 yuan, thiab tus nqi tsim tawm txhua hli yog suav ua 4 lab. Qhov feem pua ntawm tus nqi xauj tsev rau dej thiab hluav taws xob rau tus nqi tsim tawm yog = 15/400 = 3.75%. Cov nuj nqis nyiaj txiag:
Vim yog qhov tsis sib xws ntawm cov voj voog txais thiab cov voj voog them (peb yuav cov khoom siv nyiaj ntsuab thiab cov neeg siv khoom them nyiaj txhua hli hauv 60 hnub), peb yuav tsum tuav cov nyiaj tsawg kawg yog 3 lub hlis, thiab tus nqi paj laum hauv txhab nyiaj yog 1.25-1.5%.
Yog li ntawd: cov nuj nqis tswj hwm yuav tsum suav txog li 5% ntawm tag nrho cov nqi muag khoom.
7. Cov Nyiaj Tau Los
Xav txog lub tuam txhab txoj kev loj hlob mus sij hawm ntev thiab kev pabcuam zoo dua rau cov neeg siv khoom, peb cov txiaj ntsig yog 10% -15%.
