Ol samting i narapela narapela namel long ol Kasting bilong Dai na Dai Fonging:
1. Signifikens bilong Distinguishing Namel long Dai Kasting na Dai Forging (Liked Fojings):
Sampela namel oganaisesen long Saina, wantaim ol komponen na ol komplit pat manifakta, i save mekim ol hap oda na bihain painim ol domestik manifakta long kamapim ol. Bikos ol prodaksen proses bilong dispela tupela kain blank i narapela narapela, ol prais bilong ol maket nau tu i narapela narapela; prais bilong laspela i antap moa long namba wan. Sapos dispela tupela kain blank i no inap long luksave long en, sapos yumi kolim prais bilong ol dai kasting i go daun taim yu kisim bisnis, dispela bai kamapim ol asua bilong bisnis, na dispela bai bagarapim winmani o ol samting i lus tu.
Profesenel kasting na wokim ol kampani bilong wokim ol samting. Ol i ken kisim bisnis sapos ol i ting olsem laspela em i wanpela dai kasting na ol i ken kamapim long yusim ol tumbuna dai kasting proses. Bihain long ol i opim dai kasting mold, ol blank i kamap long dai kasting proses i save kamap planti taim i gat ol liklik hul, porositi, o ol samting i no stret long pes, na dispela i kamapim ol blank i no kwalifai na long pinis bilong en ol lus i no gat wok long en.
2. Rilesensip bitwin Dae Kasting & Fojing, Likwid Fojing, mo Kontiniu Kasting & Fojing Proses:
As bilong wok bilong kasting i go het na pasin bilong giaman em long pinisim wok bilong kasting na wokim ol samting insait long wankain set bilong ol mol long wanpela masin tasol. Kontiniu kasting & forging i no wan niu proses; ol stiatok bilong en i gat longpela histori. Proses we i moa tipikol mo simpol kontinu blong kasting & forging hemi proses blong forging we yu save gud long hem. Dai kasting & forging, long tok piksa, em i wanpela proses we i yusim ol speselis ikwipmen i gat bikpela otomatik long kamapim ol wara forging wantaim ol straksa i kompleks olsem ol nomol dai kasting. Bikos long dispela, ol dai kasting na ol nomol dai kasting i no isi long luksave long en long lukluk. Wanpela proses i gat wankain kwaliti olsem ol blank i kamap long rot bilong kontinu kasting & forging em "cast- bihain{6}}}forge" proses. Kas- bihain-}forge proses i save kamap planti taim: blank prodaksen i nidim tupela set bilong ol mol, wanpela bilong manuel nomol metal mold kasting, na narapela bilong presis forging yusim wanpela friksen pres o haidrolik pres.
3. Introdaksen long Dai Kasting na Forging Proses:
Dai kasting na forging em i wanpela proses ol i mekim long wanpela speselis dai kasting na wokim masin. Besik proses bilong en i gat ol samting ol i wokim long ain ol i wokim na pulapim long hul bilong mol long liklik o bikpela spit. Mold i gat ol ples we i save muvmuv, mo oli putum presa taem ol aean we oli melt oli kam kolkol, oli mekem blank we i blank. Dispela proses i rausim ol shrinkage cavities na porositi bagarap long blank na i winim wanpela giaman, fragmented grein straksa. Ol ovarol mekanik samting bilong blank i kamap gutpela tru. Moa yet, ol blank ol i wokim long dispela proses i save kamapim wanpela pes pinis bilong gret 7 (Ra1.6), wankain olsem ol pes i kamap long kol ekstrusen o masin, i soim wanpela metalik lait. Olsem na, mipela i kolim dai kasting na wokim wanpela "limit foming proses," wanpela moa wok i go aut moa long "no{8}}}kat, low-}majin proses." Narapela gutpela samting bilong dai kasting na giaman em olsem, antap long kamapim ol tumbuna kasting samting, em i ken yusim tu ol aloi ol i bin wokim na ol i wokim ol aloi long kamapim ol hap i gat ol strongpela straksa tru. These alloy grades include: hard aluminum alloys, super-hard aluminum alloys, and forged aluminum alloys, such as LY11, LY12, 6061, 6063, LYC, LD, etc. The tensile strength of these materials is nearly twice that of ordinary cast alloys, which is of greater significance for components such as aluminum alloy ol wil bilong otomotiv na ol freim we i nidim bikpela strong na impak resistens.
4. Ol rot bilong luksave long dispela tupela kain blank:
Long lukluk tasol, em i hat long luksave long ol blank i stap nating we dispela tupela proses i kamapim. Sapos yumi lukim wanpela hap i pinis, em i hatwok moa long luksave long en. Olsem na, yumi ken skelim na skelim tasol long narapela lukluk: Namba wan, dai-cast pat em ol "straksel hap," na ol dai-cast forgings em ol "ol hap bilong wok." "Ol hap bilong straksa" na "ol hap i no wok" em ol tok i stret wantaim. Laswan i minim ol pat we i mas stanap strong long impak, hae tempereja, presa, paoa (fos), mo i nidim tritmen blong surface (olsem anodising) mo tritmen blong hat (solusen strong). Ol samting i save kamap em ol samting bilong ensin blok, ol wil hab, ol piston, ol stik i konektim, ol brek su, na ol valv bodi bilong valv i gat pneumatik o haidrolik (olsem ol komon tri{7}}pos bilong valv). Ol samting bilong bipo i gat ol samting olsem ol freim bilong dua bilong ka, ol panel panel, na ol samting bilong ensin. Namba tu, ol i ken skelim long ol samting bilong skin. Ol i save putim ol dais long ol aloi bilong ol kast; ol narapela mak bilong aloi i save kamap planti taim long rot bilong yusim ol samting bilong kastim na wokim ol samting bilong dai. Namba tri, ol i ken skelim long ol samting ol i mas mekim long pes bilong ol samting bilong ples i stap nating. Olsem, ol aluminium dai kasting i gat silikon, na ol blank i kamap long rot bilong dai kasting proses i gat ol maikropores long ausait pes bilong ol. Bihain long anodizing, dispela samting bai gat ol "blakpela mak" antap long pes. Olsem na sapos blank i nidim anodising, em bai no inap kamap long yusim ol nomol dai kasting proses. Namba foa, ol i ken skelim long metalografik straksa. Ol i isi long luksave long ol dais na dai kasting forgings long ol metalografi. Dispela namba wan i gat wanpela dendritik olsem-cast straksa, taim laspela i gat wanpela yunifom, hap hap i bruk bruk olsem-cast straksa.
5. Rausim sampela tingting kranki:
(1) Mipela i no inap bilip moa olsem vekim infiltresen bihain long dai kasting inap stretim ol shrinkage caviti na porositi defek long ol dai kasting, na tu mipela i no inap bilip olsem vekim dai kasting i ken yusim long kamapim ol wok hap we i nidim kontinu kasting na foging proses. Taim indastri teknoloji i go het, yumi mas bihainim wanpela tingting bilong saiens we i save bihainim ol taim long ol tingting na tingting bilong yumi.
(2) Tupela vekim dai kasting na ol nomol dai kasting i save karim hevi long ol shrinkage caviti na porositi bagarap. Vakum dai kasting i save mekim liklik wok tasol long helpim long vent taim yumi skelim wantaim ol nomol dai kasting; em i no wok gut olgeta long ol hul bilong shrinkage na porosity i kamap long shrinkage bilong melten metal long taim bilong fez transfomesen (we insait em i wanpela vekim, i no gat ges). Namba tri, wan komon mistek we ol profesenol oli mekem i we, nomata oli save se blank ia oli no save prodiusum yusum nomol dae kasting, oli jusum wan proses we oli singaotem "rives pans indaerek mo pat blong ekstrusen." Ol i popaia na bilip olsem dispela pasin i winim wankain samting olsem pasin bilong wokim wara, na dispela i no stret olgeta. As bilong "reves pans ekstrusen" em i wanpela dai kasting proses yet! "Foking wantaim wanpela fowet punch i karamapim ful projekted eria" em i trupela likid forging proses.
6. Konklusen:
Distinguishing namel long ol nomol dai kasting na dai-cast forgings em i wanpela wok i gat mining tru yet. Nomata we ol rod ia oli no had blong save gud, plante long hem i involvem ol skil blong tingting mo tingting.
