Xa iinjineli zichaza i-resin-coated sand casting kwiindawo zetsimbi ezichanekileyo, abakhethi nje inkqubo-bazimisele ukuzinza kwe-dimensional phantsi koxinzelelo lwe-thermal, ukunyaniseka komphezulu we-machining yesibini, kunye ne-microstructural consistency kwimida yeqashiso. Yiyo loo nto ikhokela inkqubo ye-hydraulic ye-OEMs, abavelisi bempompo, kunye nababoneleli bezixhobo ze-oyile besanda umthombo ovela kwiingcali. i-resin-coated sand casting factory amaqabane-hayi iziseko jikelele.
Siye sabona iiprojekthi ezininzi zilibazisekile ngenxa yokulindela okungahambelaniyo: umzobo ubiza ± 0.15 mm kwizindlu ze-cylinder ezingama-320 mm, kodwa i-Foundry ihambisa ± 0.4 mm njengomgangatho-kwaye igxeka "intshukumo yesanti." Okanye i-cobalt alloy nozzle iyaqhekeka ngexesha lovavanyo loxinzelelo ngenxa yokuba ulwakhiwo lwengqolowa aluzange luqinisekiswe phambi komatshini. Ezi ayizizo iimeko ezinzima. Ziyimpawu zesakhono esiqhekezayo-apho ukuphosa, unyango lobushushu, kunye nokuchaneka kwe-CNC kuhlala kumasebe ahlukeneyo, ngaphandle kokuphendula okwabelwanayo malunga nokusebenza kwenxalenye yokugqibela.
Kulapho ukwenziwa okudityanisiweyo ngokuthe nkqo kutshintsha iziphumo. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ukugatywa kwentlabathi egqunywe ngentlaka akwenziwanga yodwa. Linyathelo lokuqala kwikhonkco elilawulwa ngokuqinileyo: isiqinisekiso semathiriyeli ekrwada (AMS 5387, T800, ASTM A487), ijometri engundoqo eqinisekisiweyo ngokuchasene ne-GD&T callouts kusetyenziswa ukuskena kwe-3D yokukhanya, ukunyangwa kweqokobhe kujongwe ngokwe-ISO 9001-ixesha/iintonga zobushushu, kunye nokunyanzeliswa kwangoko kwe-CMM. iqala. Sifaka i-piston pump cylinder housings kunye nobukhulu bodonga ukusuka kwi-12 mm ukuya kwi-48 mm ngokuthulula okukodwa-kwaye ubambe i-0.08 mm flatness kwi-flange ephezulu. Njani? Ngokulawula umlinganiselo we-binder, uxinzelelo olubambeneyo, kunye nokutshisa kwangaphambili kokungunda ngaphakathi kwe-±5°C. Hayi ithiyori. Idatha elinganisiweyo, ifakwe, ihlaziywe, iphindwe.
I-resin-coated sand cast igqwesileyo apho utyalo-mali lubetha imida yeendleko-kwaye isanti eluhlaza ayinaso isisombululo. Kodwa impumelelo ixhomekeke kwizinto ezintathu ezingaxoxiswana: Okokuqala, uyilo lokungunda ngokwezinto ezithile. I-cobalt-nickel alloys njenge-AMS 5387 ifuna amazinga okupholisa acothayo kune-ductile iron; sihlengahlengisa ubukhulu beqokobhe kunye ne-gating ukunqanda ukushwabana kwe-porosity kwiindlela ezibalulekileyo zokuhamba. Okwesibini, kwinkqubo yokuqinisekiswa kwe-metallurgical. Lonke ubushushu bufumana uhlalutyo lwe-spectrographic kunye nesampulu eqinile-kungekhona nje kwirisithi, kodwa emva kokuphosa kwaye kwakhona emva kokufakwa kwesisombululo. Okwesithathu, machining-ingqondo yokuqala. Iinjineli zethu zokuphosa ziphonononga imizobo yakho *ngenkqubo yeCNC*. Ukuba unyamezelo lwe-0.05 mm luhlala kumphezulu oza kusilwa kamva, siphucula uyilo lokuphosa kunye nesibonelelo sokugqiba-hayi ukuhlangabezana ne-spec, kodwa sinciphise iindleko zakho zizonke.
Abanye baphikisa ukuba isanti egqunywe nge-resin ayinakuhambelana nokugqitywa komphezulu wotyalo-mali. Yinyani-kwimigangatho ekrwada, iRa 6.3 µm iqhelekile xa ithelekiswa neRa 1.6 µm kutyalo-mali. Kodwa nantsi into ebalulekileyo: ukuba inxalenye yakho ifuna ukucolwa kokugqibela okanye ukuhoya, loo mahluko uyanyamalala. Kwaye isanti eqatywe intlaka inikezela ukuphindaphindwa komgangatho ophezulu kwiibhetshi eziphakathi (ama-50-500 iipcs) ngaphandle kokusebenzisa izohlwayo ze-amortization. Kwiivalvu zoxinzelelo ezinezihlalo zokutywina ezidibeneyo, iziseko zempompo ezifuna ukulungelelaniswa kwe-bolt-hole kwi-1.2-meter spans, okanye i-winch center shaft rollers exhomekeke kwimithwalo yokugoba ye-cyclic-sihambise i-99.2% isivuno sokuqala sokudlula kwiinyanga ezili-18 zemveliso ye-serial. Akukho zilophu zokuphinda zisebenze. Ayimangalisi into yokusilela kwe-NDT. Kuyalandeleka, kubhalwe, kuqinisekiswe ngokusebenzayo iinxalenye.
Ukuba uvavanya a i-resin-coated sand casting factory, buza imibuzo emithathu: Ngaba banokukubonisa iingxelo zeebhetshi ezintathu zokugqibela zebakala lakho le-alloy-kuquka amandla okuqina, ukuqina, kunye nobukhulu beenkozo? Ngaba bayayenza inkqubo yokuhlola i-CMM kwimilinganiselo ye-cast-hayi nje abokugqibela ngoomatshini? Kwaye ngaba iinjineli zabo zithetha ulwimi lwakho-kungekhona nje isiNgesi, kodwa i-GD&T, ASME Y14.5, kunye nenjongo esebenzayo emva kokunyamezela kwakho? EQINGDAO QIANGSENYUAN TECHNOLOGY, ezo ayizobhokisi zokukhangela. Ziqheliselo lwemihla ngemihla. Isiphumo? Amalungu asinda kwiiyure ezingama-20,000+ kuxinzelelo oluphezulu lwe-hydraulic manifolds. Izixhobo ezigcina ingqibelelo yesitywina kwi-450 ° C kwizixhobo ezisezantsi. Kwaye intsebenziswano eyakhelwe phezu kobunjineli obucacileyo-hayi nje imihla yokuhanjiswa. Ukwenziwa ngokuchanekileyo kuqala ngenjongo. Iphela ngobungqina.
