Overview of Valve Casting

1. He aha ke kauʻana

Ua nininiʻia ka wai wai i loko o kahi lua kupapaʻu i kahiʻano kūpono no ka'āpana, a ma hope o ka palekana, kahi i kapaʻia ai ka hale. ʻEkolu mau mea nui: Alloy, hoʻohālike, ka hoʻohālikelikeʻana a me ka hoʻoponoponoʻana. ʻO ka pono nui loa: Hiki ke hoʻokumuʻia nā'āpana paʻakikī.

2. E hoʻomohala ana i ke kauʻana

Hoʻomaka ka hana i nā makahiki 1930 e hoʻohana ana i nā mīkini pneumatic a me nā kaʻina o nā papa.

Ua hōʻikeʻia keʻano o keʻano o keʻano o keʻano ma 1933

I ka makahiki 1944, ua puka mai keʻano o keʻano o keʻano o keʻano pale

ʻO CO2 i hōʻikeʻia ka wai aniani wai i puka mai i ka makahiki 1947

I ka makahiki 1955, ua puka mai keʻano o keʻano o keʻano o keʻano

I ka makahiki 1958, ka res re res re re res res-cake sur jolld

I ka makahiki 1967, ua puka mai ka leleʻana o ke kahe

I ka makahiki 1968, ua puka mai ke aniani wai me ka paʻakikī o ka mea paʻakikī

I nā makahiki he 50 i hala iho nei, nā ala hou o ka hanaʻana i nā pale e pili ana i keʻano, e like me nā papa hana bely. E like me kā Temerifugal Ke kāhea nei, ke kiʻekiʻe kiʻekiʻe o ka Cyegrifug

3. Nā hiʻohiʻona o ka mālamaʻana

A.ʻO ADAPTICATION ADAPTOLITALL a hoʻololi. Nā huahana waiwai āpau āpau. ʻAʻole palenaʻiaʻo Casting e ka paona, ka nui a me keʻano o ka'āpana. Hiki i ke kaumaha ke lilo i mau mea liʻiliʻi mai nā haneli he mau haneli, hiki i ka pā nui ke hiki mai ka 0.3mm a hiki i 1m, a hiki i keʻano keʻano paʻakikī.

B.ʻO ka hapa nui o nā mea e hoʻohanaʻia a me nā mea kōkua Aruxilialy

Hiki i nā C. Hiki ke hoʻomaikaʻi i ka pololei o ka dimensional a me ka maikaʻi o nā hale kiaʻi ma o kaʻenehana kūʻai, no keʻokiʻoleʻia.
