mankhwala Mwatsatanetsatane

Tags mankhwala

Kulemera kuchuluka: 0.1-50kg
luso: Sand kuponyera, amamwalira akuponya, yokoka akuponya, ndalama kuponyera
ntchito: Pump, valavu, galimoto, ulimi, ena munda makina.

Zotayidwa kuponyera
castings zotayidwa anapanga ndi kuthira achitsulo mu amatha kuumba zomwe zinapangidwa ndi chitsanzo cha mankhwala ankafuna. Mitundu itatu yofala njira akamaumba ntchito kubala castings zotayidwa:

Kufa akuponya
Die casting uses pressure to force molten aluminum into a steel die (mold). This type of casting is often used for mass production of parts, which require a minimum amount of finishing and machining. Die casting has short cycle times but high costs for tooling. The pressurized casting system creates a high strength skin but weaker interior than permanent mold casting. 

Nkhungu Permanent akuponya
Permanent mold casting uses steel (or other metal) molds and cores. Strong castings are formed by pouring aluminum into the mold. Permanent molds are used to create highly repeatable parts with consistency. Their rapid cooling rates generate a more consistent microstructure, which can improve the mechanical properties significantly.

Sand kuponyera
castings mchenga analengedwa ndi atanyamula osakaniza chabwino mchenga padziko chitsanzo cha mankhwala ankafuna. Chitsanzo ndi akuluakulu pang'ono kuposa chomaliza mankhwala kuti apeze shrinkage wa zotayidwa pamene yozizira. Sand kuponyera ndi ndalama chifukwa mchenga ndi reused maulendo angapo pa. Ndi zothandiza kulenga mwakemu lalikulu kapena mwakemu ndi ziwembu mwatsatanetsatane. Upfront ndalama tooling ndi otsika koma pa mitengo mbali ndi apamwamba, kupanga mchenga kuponyera yabwino kwa castings apadera kuposa kuŵeta.
