A: ʻO ka hoʻoheheʻe ʻana he ʻano hoʻoheheʻe ʻia kahi e ninini ʻia ai ka wai i hoʻoheheʻe ʻia i loko o kahi keʻena kaomi, hoʻopiha ʻia kahi lua o kahi pahu kila i ka wikiwiki kiʻekiʻe, a hoʻopaʻa ʻia ka wai i hoʻoheheʻe ʻia ma lalo o ke kaomi e hana i kahi hoʻolei.ʻO nā hiʻohiʻona nui o ka hoʻoheheʻe make e hoʻokaʻawale iā ia mai nā ʻano hana hoʻoheheʻe ʻē aʻe he kiʻekiʻe kiʻekiʻe a me ka wikiwiki kiʻekiʻe.

ʻO nā mīkini hoʻoheheʻe make, nā mea hoʻoheheʻe die-casting a me nā mold die-casting nā mea nui ʻekolu o ka hana make-casting a he mea pono ʻole.ʻO ke kaʻina hana make-casting ʻo ia ka hui kūlohelohe o kēia mau mea ʻekolu, e hiki ai i ka hana paʻa, rhythmic a me ka maikaʻi o nā castings me ke ʻano, ka maikaʻi o loko, a me ka nui o nā kiʻi a i ʻole nā ​​koi o ka ʻaelike.

A:

(1) Hiki iā ia ke hoʻokō i nā koi hana o nā castings make.

(2) He haʻahaʻa ka helu hoʻoheheʻe, liʻiliʻi ka pae wela crystallization, maikaʻi ka wai i ka mahana ma luna o ka helu heheʻe, a liʻiliʻi ka nui o ka shrinkage ma hope o ka solidification.

(3) Ua lawa ka ikaika a me ka plasticity i ke kiʻekiʻe wela, a me ka haʻahaʻa wela brittleness.

(4) ʻO nā waiwai kino a me nā kemika maikaʻi e like me ke kūpaʻa ʻaʻahu, ka conductivity uila, ka hoʻoili wela, a me ke kū ʻana o ka corrosion.

A: ʻO ka mea maʻamau, ʻo ka noi maoli i ka ʻoihana make-casting ʻaʻole 100% alumini maʻemaʻe, akā me kahi ʻike alumini mai 95% a i 98.5% (make-cast alumini alumini me ka hana anodizing maikaʻi), a pono e komo ka alumini maʻemaʻe. ʻoi aku ma mua o 99.5% aluminika (E like me ka alumini rotor die casting).Ma muli o ka maikaʻi o ka thermal conductivity a me ka anodizing waiwai, hoʻohana pinepine ʻia ka alumina i ka wela wela a me ka mālama ʻana i ka ʻili kahi kiʻekiʻe nā koi kala.

Hoʻohālikelike ʻia me ka alumini alumini maʻamau die-casting (e like me ADC12), ma muli o ke kiʻekiʻe kiʻekiʻe o ka silicon content, ʻo ka shrinkage rate he liʻiliʻi 4-5%;akā, ʻaʻohe silika ka alumina, ʻo ka shrinkage rate he 5-6%, no laila, ʻaʻohe hopena anodizing o ka alumini alumini maʻamau.

A: Hiki ke hoʻokaʻawale ʻia nā mīkini hoʻoheheʻe make i ʻelua mau ʻano, nā mīkini hoʻoheheʻe keʻena wela a me nā mīkini hoʻoheheʻe keʻena anuanu.Aia ka ʻokoʻa i ka nui o ka ikaika e hiki ai iā lākou ke pale aku.ʻO ke kaomi maʻamau mai 400 a 4,000 tons.ʻO ka hoʻoheheʻe ʻana o ke keʻena wela he mea hoʻoheheʻe ʻia, wai, semi-wai metala i loko o kahi wai metala e hoʻopiha ai i ka ʻōpala ma lalo o ke kaomi.Hiki ke hoʻohana ʻia ka hoʻoheheʻe ʻana i ke anuanu no nā metala hoʻoheheʻe make ʻaʻole hiki ke hoʻohana ʻia i nā kaʻina hana hoʻoheheʻe make keʻena wela, me ka aluminika, ka magnesium, ke keleawe, a me nā ʻāpana zinc me nā mea alumini kiʻekiʻe.Ma kēia kaʻina hana, pono e hoʻoheheʻe mua ʻia ka metala i loko o kahi kīʻaha ʻokoʻa.Hoʻololi ʻia kekahi nui o ka metala i hoʻoheheʻe ʻia i kahi keʻena hoʻoheheʻe ʻole a i ʻole nozzle;ʻo ka ʻokoʻa ma waena o ke keʻena wela a me ke keʻena anuanu inā paha i hoʻokomo ʻia ka ʻōnaehana injection o ka mīkini hoʻoheheʻe make i loko o ka hopena metala.

A: Hot keʻena make hoolei mīkini: zinc alloy, magnesium alloy, etc.

ʻO ke keʻena anuanu make e hoʻolei ana i ka mīkini: zinc alloy, magnesium alloy, aluminum alloy, copper alloy, etc.

ʻO ka mīkini hoʻolei make kū pololei: zinc, aluminika, keleawe, ke kēpau, tin;

A:

1. He hana hoolei maikai

2. Haʻahaʻa haʻahaʻa (2.5 ~ 2.9 g / cm 3), ikaika kiʻekiʻe.

3. ʻO ka wai metala me ke kiʻekiʻe kiʻekiʻe a me ka wikiwiki o ke kahe ʻana i ka wā o ka hoʻolei ʻana

4, maikaʻi ka huahana, paʻa ka nui, a maikaʻi ka hoʻololi;

5, kiʻekiʻe kiʻekiʻe hana pono, ka helu o nā manawa i hoʻohana ʻia ka mold die-casting;

6, kūpono no ka nui o ka hana nui, hoʻihoʻi waiwai maikaʻi.

A: Hoʻohana maʻamau i ka hoʻomaʻamaʻa ʻana o ka alumini alloy make-casting parts: electrophoretic paint, electroplating, fuel injection, sand blasting, shot blasting, anodizing, baking varnish, kiʻekiʻe wela baking varnish, anti-rust passivation a pēlā aku.
