Bayanin Sirri: Sirrinka yana da matukar mahimmanci a gare mu. Kamfaninmu yayi alkawarin kar a bayyana keɓaɓɓun bayananku ga kowane fallasa tare da izini na bayyananne.
Simintin simintin kusa-net ba fasaha ce ta daban ba - ƙira ce da falsafar masana'anta waɗanda ke amfani da madaidaicin simintin saka hannun jari don samar da sassa kusa da ma'auni na ƙarshe kamar yadda zai yiwu, rage injin CNC zuwa mafi mahimmancin saman. Sakamakon: 40-60% ƙarancin lokacin injina, 30-50% ƙananan sharar kayan abu, da jimlar farashin ragi na mallakar mallaka wanda zai iya canza fasalin tattalin arziki.
"Near-net-siffa" yana nufin simintin gyare-gyaren da ke buƙatar ƙira kaɗan don isa girma na ƙarshe. A cikin jefa jari, wannan yana nufin:
Kwatanta wannan da simintin yashi, inda injina na 2-5mm daidai yake, kuma kusan kowane saman aiki yana buƙatar injina. Ko zuwa machining daga billet, inda 40-60% na albarkatun kasa ya zama kwakwalwan kwamfuta.
Yawancin masu siyan OEM suna mai da hankali kan yanki na simintin simintin gyare-gyare ba tare da la'akari da jimlar kuɗin mallakar (TCO). TCO ya haɗa da:
Lokacin da aka ƙididdige waɗannan farashin, ajiyar kuɗi daga simintin saka hannun jari na kusan-net ɗin ya zama mai tursasawa.
Nazarin Case : Mai yin bawul wanda ke samar da jikin bawul 5,000 a kowace shekara idan aka kwatanta da simintin yashi + cikakken machining vs. zuba jari + ƙaramin injin:
| Abun Kuɗi | Hanyar Simintin Yashi | Hanyar Zuba Jari | Adana |
|---|---|---|---|
| Farashin yanki na simintin gyare-gyare | $18.00 | $28.00 | - $10.00 |
| Kudin kayan aiki (ciki har da guntu) | $6.50 | $3.20 | + $ 3.30 |
| Farashin CNC machining | $22.00 | $9.50 | + $ 12.50 |
| Kayan aiki amortization | $0.80 | $1.20 | - $0.40 |
| Kudin dubawa | $3.50 | $1.80 | + $ 1.70 |
| Jimlar kowane yanki | $50.80 | $43.70 | + $ 7.10 (14%) |
Farashin yanki na simintin saka hannun jari ya kasance dala 10 mafi girma, amma jimlar farashin kowane yanki ya kasance ƙasa dala $7.10 - raguwar 14% na TCO da aka yi ta hanyar rage lokacin injina da sharar gida.
Ƙarfin fasaha da yawa na simintin saka hannun jari yana ba da damar samar da siffa ta kusa-net:
