Ngawaphi amaxwebhu ekufuneka abathengi bawacele?
Amaxwebhu aqhelekileyo aquka izatifikethi zezinto eziphathekayo, iingxelo ezinomlinganiselo, iirekhodi zokuhlola, izicwangciso zokulawula, i-PPAP xa kufuneka, i-RoHS okanye i-REACH, kunye neengxelo zesenzo sokulungisa.
Zithintelwa njani iziphene zesitampu kwimveliso?
Iziphene zincitshiswa ngokuphononongwa kweDFM, ukugcinwa kwesixhobo, ukuvunywa kokuseta, izinto ezininzi ezizinzile, iitshekhi zomsebenzisi, iigeyiji, kunye neendlela ezicacileyo zokwamkelwa.
Imibuzo Ebuzwa Rhoqo
Yintoni umahluko phakathi kweCpk kunye nePpk kulawulo lomgangatho wesitampu sesinyithi?
I-Cpk ilinganisa amandla enkqubo yexesha elifutshane usebenzisa ukwahluka kweqela elingaphantsi (σ ngaphakathi), ngelixa i-Ppk ilinganisa isakhono sexesha elide kusetyenziswa ukwahluka ngokubanzi (σ jikelele). I-Cpk ibonisa ukubanakho kwenkqubo ukuba ibigxile ngokugqibeleleyo, ngelixa i-Ppk ibala iishifti kunye nokuhamba ngokuhamba kwexesha. Enyanisweni, i-IATF 16949 idinga izifundo zokuqala zokukwazi ukusebenzisa i-Ppk (ubuncinane beengxenye ze-300) kunye nokubeka iliso okuqhubekayo usebenzisa i-Cpk. I-Cpk ye-1.33 okanye ngaphezulu iyimfuneko eqhelekileyo yemoto, oku kuthetha ukuba inkqubo yokusabalalisa ihambelana nokunyamezela kunye nomda.
Kufuneka kuhlolwe kangaphi ukufa kwesitampu ngexesha lemveliso?
Ukufa kokuhlolwa rhoqo kuxhomekeke kwisixhobo, ukuntsonkotha, kunye nomthamo wemveliso. Kwizitampu zentsimbi eziqhelekileyo ezisebenza ngesantya esiphakathi, jonga kufa rhoqo kwi-10,000-25,000 imivimbo. Kwisantya esiphezulu sokufa (> 300 SPM) okanye izinto ezirhabaxa ezifana nentsimbi engenasici, hlola yonke imivumbo eyi-5,000–10,000. Izitampu ezibalulekileyo okanye ezinxulumene nokhuseleko zinokufuna iitshekhi zokufa rhoqo. Ngalo lonke ixesha ubhala imeko yokufa kwaye ulandele iipateni zokunxiba ukuze ulungiselele iishedyuli zothintelo lolondolozo.
Sesiphi isicwangciso sesampulu se-AQL endifanele ndisisebenzise xa kuhlolwa impahla engenayo?
Kwizinto ezingenayo eziluhlaza (i-coil steel, i-aluminium), i-ANSI / ASQ Z1.4 (elingana ne-ISO 2859-1) iNqanaba le-II lokuhlola oluqhelekileyo luqhelekileyo. Sebenzisa i-AQL 1.0 kwiimpawu ezibalulekileyo (ikhemistri, iipropati zemishini) kunye ne-AQL 2.5 yeempawu ezincinci ze-cosmetic okanye i-dimensional. Kwiindawo ezikhuselekileyo ezikhuselekileyo okanye abaxhasi abatsha, qinisa kwi-AQL 0.65 okanye uphumeze i-100% yokuhlola kuze kube yilapho umthengisi ebonisa umgangatho ohambelanayo ngaphezu kwe-5-10 amaqashiso alandelelanayo.
Ngaba i-SPC ingasetyenziswa kwidatha yophawu (ukudlula / ukungaphumeleli) kwisitampu sesinyithi?
Ewe. Ngelixa idatha eguquguqukayo (imilinganiselo eyiyo) isoloko ikhethwa kwi-SPC, iitshathi zeempawu zisebenzela ukupasa/ukungaphumeleli kweziphumo. Sebenzisa itshathi ye-p ukulandelela umyinge wamalungu aneziphene kwisampulu nganye, okanye itshati ye-np yobalo lokwenene lweziphene xa ubungakanani besampulu bungatshintshi. Iitshathi zophawu azinovakalelo oluncinci kuneetshathi eziguquguqukayo - udinga iisayizi ezinkulu zesampulu ukubona utshintsho. Ukuba uhlobo lwesiphene luyaphindaphindeka, cinga ukutshintshela kumlinganiselo oguquguqukayo (umzekelo, ukulinganisa ubude be-burr endaweni yokupasa/yokusilela ukukhangela i-burr) ukunika ujongo oluchanekileyo lwe-SPC.
Ithini indleko eqhelekileyo yokuphumeza inkqubo yokulawula umgangatho wokusebenza kwesitampu?
Kwivenkile yesitampu esiphakathi (10–30 press), inkqubo yolawulo olusemgangathweni olupheleleyo equka isiqinisekiso se-ISO 9001, isoftwe ye-SPC esisiseko, izixhobo zeCMM, ukuhlolwa kombono kwimigca ebalulekileyo, kunye noqeqesho ludla ngokudla i-$150,000–400,000 yeedola kunyaka wokuqala, kunye $50,000–$120,000 kwiindleko zokusebenza ngonyaka. Ukongeza i-IATF 16949 isiqinisekiso sonyusa iindleko zonyaka wokuqala nge-80,000 yeedola ukuya kwi-200,000 yeedola. Nangona kunjalo, imbuyekezo inkulu: imisebenzi emininzi ibona amazinga e-scrap ehla nge-30-50% kwaye amabango ewaranti ehla ngama-40-70% kwiinyanga zokuqala ezili-18 zenkqubo ephunyezwe ngokufanelekileyo.
Ukuqukumbela
Ukulawulwa kwekhwalithi yentsimbi ayingomsebenzi omnye - yinkqubo yemigangatho edibeneyo, iindlela, iinkqubo, kunye noqeqesho olusebenzisanayo ukuhambisa amacandelo angaguqukiyo, ahambelanayo. Ukusuka ekuqinisekisweni kwezinto ezingenayo ngemveliso ejongwe yi-SPC ukuya kuphicotho lokugqibela lweCMM, umaleko ngamnye wongeza ukhuseleko kwiziphene ezifikelela kumthengi wakho.
