I-Progressive dies yakhelwe umthamo ophezulu, iindawo ezinamanyathelo amaninzi; Ikhompawundi iyafa igqwesile kwindawo echaneke kakhulu, indawo enye.
Ndingayikhetha nini idayi ekhompawundi endaweni yokufa okuqhubekayo?
Khetha i-ufa odibeneyo xa inxalenye yakho ifuna ukunyamezelwa kweempawu eziqinileyo (± 0.01-0.025 mm), xa ukusetyenziswa kwezinto eziphathekayo kubaluleke kakhulu (ingakumbi nge-alloys ebiza kakhulu), xa umthamo wonyaka uphakathi (10,000-500,000 iinxalenye), xa inxalenye yejometri ingagqitywa kwi-hit enye, okanye xa i-tooling ixesha lokuhambisa and budget ilinganiselwe. I-Compound dies ikwakhethwa kwizibane zombane, iiwasha ezichanekileyo, iigaskets, kunye nezibiyeli ezisicaba ezinemingxunya eqinileyo.
Ingaba ukufa okuqhubelekayo kunokuthatha indawo yokufa okudityanisiweyo kuzo zonke izicelo?
Hayi. Ngelixa i-ufa oqhubekayo inokuvelisa iindawo ezifanayo njenge-ufa odibeneyo, kukho iimeko apho ukufa kwekhompawundi kuphezulu. Amacandelo afuna ukuchaneka okugqithisileyo phakathi kweempawu ezixhamlayo kwikhompawundi ziyafa ngenxa yokuba zonke iimpawu zisikwe ngaxeshanye - akukho mpazamo yokunyuka kwesikhululo ukuya kwisikhululo. Ukongeza, kwimiqulu ephakathi, ixabiso elisezantsi lesixhobo sokufa kwekhompawundi lenza ukuba libe noqoqosho ngakumbi. I-Progressive iyafa iphinda ichithe imathiriyeli eninzi ngenxa ye-carrier strip skeleton, ebaluleke kakhulu xa isitampu sezinto ezibizayo.
Ukusetyenziswa kwezinto eziphathekayo kuthelekiseka njani phakathi kokuqhubela phambili kunye nokufa okudibeneyo?
I-Compound ifa ngokuqhelekileyo ifikelela kuma-80–95% okusetyenziswa kwemathiriyeli kuba ikhupha iindawo ezingenanto ngokuthe ngqo kwiphepha okanye umcu ngaphandle kwenkunkuma yomthuthi. I-Progressive dies ngokuqhelekileyo ifikelela kwi-60-85% yokusetyenziswa ngenxa yokuba i-carrier strip (skeleton web) ehambisa iindawo phakathi kwezikhululo zisebenzisa izinto. Kwimpahla ye-$ 30 / kg kwi-80% vs 65% yokusetyenziswa, ixabiso lexabiso lezinto eziphathekayo ngaphezu kwe-1,000,000-part run lingadlula i-$ 100,000 - ngokuphindaphindiweyo ngokwaneleyo ukulungelelanisa indlela yokufa ye-compound nakwimiqulu ephezulu.
Yintoni ixabiso eliqhelekileyo lokuwela ivolumu phakathi kwesitampu se-progressive kunye ne-ufa odibeneyo?
I-crossover yeendleko ixhomekeke kubunzima benxalenye, indleko yezinto eziphathekayo, kunye nesicatshulwa esikhethekileyo sezixhobo. Kwiindawo ezilula ezisicaba ezinokwenziwa kulo naluphi na uhlobo lokufa, i-crossover idla ngokubakho phakathi kwe-1,000,000 kunye ne-5,000,000 yamalungu. Kwiindawo ezinzima ngakumbi ezifuna imisebenzi emininzi, i-crossover inokuthi yenzeke ephantsi njengeengxenye ze-250,000 ngenxa yokuba i-ufa oqhubekayo's multi-station capabilities inikezela ngexabiso elikhulu kwi-part-part. Soloko ubala i-amortization yezixhobo zokusebenza, iindleko zexesha lomjikelo ngamnye, abasebenzi, kunye nenkunkuma yezinto eziphathekayo ukumisela eyona ndlela ichanekileyo yokuwela kwisicelo sakho.
Ukuqukumbela
Isigqibo se-ufa oqhubekayo vs ufa odibeneyo asikho malunga nokuba yeyiphi indlela "engcono" ngokwemigaqo epheleleyo - imalunga nokuthelekisa uhlobo lokufa kunye nejometri, iimfuno zokunyamezela, umthamo wemveliso, kunye nemiqobo yeendleko.
Khetha isitampu se-ufa oqhubekayo xa inxalenye yakho ifuna imisebenzi emininzi elandelelanayo (ukugqobhoza, ukubumba, ukugoba, ukwenza imali), xa umthamo wonyaka ungaphezu kwama-500,000–1,000,000 amacandelo, kwaye xa ixabiso lenxalenye nganye kwisikali ingumqhubi ophambili.
Khetha i-ufa odibeneyo isitampu xa inxalenye yakho inokugqityezelwa kwi-hit enye, xa ukunyamezela-to-feature ukunyamezela kubaluleke kakhulu (± 0.01-0.025 mm), xa ukusetyenziswa kwezinto eziphathekayo kufuneka kwandiswe, xa umthamo uphakathi (10,000-500,000 iinxalenye / ngonyaka), okanye xa uhlahlo lwabiwo-mali olukhokelwayo lunyanzeliswa.
Abenzi abaninzi baqala ngekhompawundi bafa kwimveliso yokuqala kunye notshintsho ukuya kwinkqubela phambili yokufa njengoko umthamo ukhula - indlela elandelwayo enciphisa utyalo-mali lwezixhobo ezingaphambili ngelixa ugcina ukukwazi ukukala.
Iinjineli zezixhobo kunye nabacwangcisi benkqubo, isitshixo kukuvavanya indawo nganye ngabanye: zoba umfanekiso we-strip wokufa okuqhubekayo, uqikelele ukubala kwesikhululo sokufa, ukubala umthamo we-crossover yeendleko, kwaye uthelekise ukusetyenziswa kwezinto. Impendulo echanekileyo ihlala igxile kwisicelo.
