Kapangidwe ka gudumu lowongolera?

Pamene kuponyera, kufupikitsa kwa madzi ndi olimba castings kuyenera kuganiziridwa mokwanira ponena za kapangidwe kake, mawonekedwe, kukula, makulidwe a khoma ndi kusintha kwa ma castings, magawo oyenerera a ndondomeko ayenera kusankhidwa, ndi kuponyera zolakwika monga mabowo a shrinkage ayenera kupewedwa. Mapangidwe a kuponyera kuthira dongosolo riser ndi wololera, ngati mukufuna kugwiritsa ntchito njira yozizira chitsulo ndondomeko, monga kukhazikitsa malo wololera, kachulukidwe wa mkati makonzedwe a kuponyera, ndi kuyesa kupewa kupezeka kwa ndende maganizo.

Chifukwa cha kapangidwe ka gudumu lowongolera kapena kusakonzekera kolakwika kwa njira yothira, chitsulo chosungunula chinawaza mwamphamvu panthawi yothira kupanga doping yachiwiri. Monga tonse tikudziwa, doping ndi mtundu wofunikira kwambiri wa zolakwika zoponya, zomwe zimawerengera theka la zolakwika zonse. Chilema ichi chikhoza kukhalapo muzojambula zonse, kuuma kwake ndikosiyana. Muyezo wowongolera zolakwika za doping umakhala makamaka zochokera ku castings Kutengera ntchito ndi kugwiritsa ntchito, kutulutsa kochulukira, kokulirapo kwa ma castings omwe ali ndi zovuta zogwirira ntchito, zonyansa kwambiri, monga kuponyedwa kwagalimoto, kuponyedwa kwa injini, kutulutsa mphamvu yamphepo, kuponyedwa kwa turbine, kuponyedwa kwa zida zamakina ndi zina zotero.

Ngakhale kutsatira udindo wa mphamvu zoponya, dziko langa zitsulo zosapanga dzimbiri kuponya teknoloji yapita patsogolo mofulumira, ndipo pang'onopang'ono anasamukira ku cholinga choponya dziko lamphamvu, ngakhale akadali nthawi yaitali. Pakali pano, dziko langa latsopano kuponyera luso. Kugwiritsa ntchito umisiri watsopano makamaka akuwonetseredwa: patsogolo mchenga kuponyera zitsulo akamaumba mzere. Chiwerengero cha ma cores chikuchulukirachulukira, ukadaulo wa mchenga wa resin umagwiritsidwa ntchito kwambiri, zitsulo zotayidwa za VOD, kutaya thovu lotayika, ukadaulo waukadaulo wamakompyuta. Rapid prototyping Kugwiritsa ntchito luso, etc. Kuwonjezeka kofulumira kwa mtengo wa castings m'dziko langa kumayamba chifukwa cha kuwonjezeka kwakukulu kwa kufunikira kwapakhomo kwa castings kumbali imodzi, ndipo kumbali ina, ndi zotsatira za kusamutsidwa kwa kupanga kupanga m'mayiko otukuka ndi zigawo kupita ku China, zomwe zimapangitsa kugwiritsa ntchito teknoloji ya kusefera pakuponyedwa kwachitika m'zaka zaposachedwa. Posachedwa, ukadaulo uwu umakhala ndi zotsatira zoonekeratu pakuchepetsa zofooka za zonyansa ndi pores, ndikuwongolera magwiridwe antchito amakina ndi kukonza ma castings, zomwe zakopa chidwi chochulukirapo kuchokera kumabizinesi oyambira.
