ʻO nā pōmaikaʻi a me nā pōʻino o ke kaʻina hoʻolei make

E kamaʻilio e pili ana i nā pono a me nā pōʻino omake hooleikaʻina hana:

pono:

(1) Hiki ke hana ʻia nā ʻāpana metala me nā hiʻohiʻona paʻakikī, nā outline akaka, nā paia lahilahi a me nā lua hohonu.Ma muli o ka mālama ʻana o ka metala i hoʻoheheʻe ʻia i ka wai kiʻekiʻe ma lalo o ke kaomi kiʻekiʻe a me ka wikiwiki kiʻekiʻe, hiki ke loaʻa nā ʻāpana metala paʻakikī e hana ʻia e nā kaʻina hana ʻē aʻe.

(2) Ka pololei o ke ana omake castingshe kiʻekiʻe, a hiki i ka IT11-13 papa, i kekahi manawa a hiki i ka IT9 grade, hiki i ka roughness ʻili iā Ra0.8-3.2um, a maikaʻi ka interchangeability.

(3) He kiʻekiʻe ka helu hoʻohana waiwai.Ma muli o ke kiʻekiʻe kiʻekiʻe o ka make castings, hiki ke hōʻuluʻulu a hoʻohana wale ʻia ma hope o ka liʻiliʻi o ka mīkini, a me kekahimake castingshiki ke hōʻuluʻulu a hoʻohana pololei.Ma kahi o 60% -80% ka nui o ka hoʻohana waiwai, a hiki i ka 90% ka hoʻohana ʻole ʻana.

(4) Hana hana kiʻekiʻe.Ma muli o ke kiʻekiʻe o ka hoʻopiha piha ʻana, pōkole ka manawa hoʻopiha, paʻa koke ka ʻoihana metala, a wikiwiki ka pōʻai hana make-casting.Ma waena o nā kaʻina hana hoʻolei like ʻole, ʻoi aku ka kiʻekiʻe o ka hana hoʻoheheʻe make a kūpono no ka hana nui.

(5) Hoʻohana maʻalahi i nā mea hoʻokomo.He mea maʻalahi ka hoʻonohonoho ʻana i ka mīkini hoʻonohonoho ma ka mold die-casting, kahi kūpono no ka hoʻolei inlay a hoʻokō i nā koi hana kūikawā kūloko o kaʻāpana hoʻoheheʻe make

hemahema:

1. Ma muli o ke kiʻekiʻe o ka hoʻopiha piha a me ka hoʻomaha wikiwiki, ua lōʻihi ka hoʻokuʻu ʻana o ke kinoea i loko o ka lua, ka hopena i ke alo o nā pores a me nā oxidized inclusions i nā ʻāpana make-casting, a laila e hōʻemi ana i ka maikaʻi o nā ʻāpana make. .Ma muli o ka hoʻonui ʻia ʻana o ke kinoea i loko o nā pores i ka wela kiʻekiʻe, e hoʻoheheʻe ʻia ka ʻili o ka die-casting.No laila, ʻaʻole hiki ke mālama ʻia ka hoʻoheheʻe ʻana me nā pores.

2. Ka hoolei makehe pipiʻi nā mīkini a me nā mea hoʻoheheʻe make a ʻaʻole kūpono no ka hana liʻiliʻi.

3. Ua kaupalena ʻia ka nui o nā castings make.Ma muli o ka palena o ka ikaika clamping o ka mīkini hoʻoheheʻe make a me ka nui o ka mold, ʻaʻole hiki ke make i nā ʻāpana hoʻoheheʻe nui.

4. Ua kaupalena 'ia nā 'ano o ka make-casting alloys.No ka meamake-castingua kaupalena ʻia nā molds e ka mahana hana, ua hoʻohana nui ʻia lākou no ka make-casting zinc alloys, alumini alloys, magnesium alloys a me ke keleawe.
