Sum mat ai mold casting hta kata chyinghka a shang wa ai shara
Dai mat mat wa ai die casting a kata chyinghka a htum mat ai shara gaw, n-gun n rawng ai hpe lu la nna, n-gun n rawng ai hpe koi lu ai kun ngu ai n re. Smooth filling gaw mat mat ai die casting a matu akyu n nga ai rai na re, hpa majaw nga yang, foam mold gaw gas material re majaw, gas n shapraw na matu n mai byin ai, dai gaw liquid metal kata de n shang na matu shi shapraw ai gas hpe n mai shapraw ai. Liquid metal gas de shang na matu ahkyak ai, n-gun n rawng ai lam nkau mi n re, n-gun n rawng ai sha, ndai yaw shada lam hpe lu la na matu, kalang lang artificial galaw shapraw ra ai, turbulence, liquid metal shock, hka ntsa e hka ntsa e gas hte slag ni hpe hka ntsa e lwi ai hte hka lim ai madang masa ni hpe shapraw kau ra ai, n-gun n rawng ai diecting hpe grai law hkra lu la na matu turbulence ni hpe mung n hkra ai.
Casting a shang wa ai shara hpe hkrang shapraw ai hta, liquid metal gaw thermal field hte sequential solidification (sh) synchronous solidification hpe hkam la lu ai, kaga ga hku tsun ga nga yang, liquid metal a katsi ai garan ginhka ai lam hpe hkam la lu ai. Hka lim ai shara gaw process sha rai tim, hot field gaw jahtum rai nga ai.
Kata na chyinghka a shang wa ai shara a npawt tara hpe grau nna sang lang dan lu na matu, foam amyu a gasification arawn alai ni hpe chye na ra ai. Foam model a gasification arawn alai law law hta, nbung laru gaw grau nna n-gun atsam nga ai. Nbung laru kaba ai aten hta, foam gasification lawan ai lam lawan ai, gasification gaw hkum tsup ai, ngam ai n pru ai. Dai zawn re ai n-gun gaw, nbung katsi ai shara (high temperature area) hta mung bung ai, n-gun n-gun n-nga ai, foam gasification n-gun n-nga ai; dai shara hta n-gun n law ai (npu na nbung katsi ai shara), ngam ai n-gun n-gun n-gun n-gun n-gun n-nga ai lam byin wa na re.
Dai majaw, n nga mat wa ai die casting gaw, kata chyinghka a shang wa ai shara hpe hkrang shapraw ai hku nna, kata chyinghka a thermal field a hkam la mai ai lam hpe chye na la lu ai. Ahkyak ai yaw shada lam gaw, liquid metal yawng hpe foam mold hpe matut mahkai nna, foam mold gasification a katsi ai bungli hpe sawn la ai shaloi, hka htung langai ngai hpe sha n-ga, foam amyu hpe katsi ai hku hkam la lu na matu re. Dai daw langai hpra a foam amyu gaw, n-gun n law ai n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-rawng ai; yawng gaw n-gun n law ai shara kaw ngam nga ai hta grau nna, nbung katsi ai shara hta tsep kawp gasification nga ai.
