Suku cadang pengecoran vakum khusus China OEM kanggo mobil kargo rel saka baja paduan Cr-Mo kanthi perawatan panas, perawatan permukaan lanLayanan mesin CNC.
Vacuum Casting uga disebut Negative Pressure Sealed Casting, Suda Pressure Casting utawaV Proses Casting. Casting meksa vakum mbutuhake nggunakake peralatan extraction online kanggo extract online nang cetakan casting, lan banjur nggunakake prabédan meksa antarane njero lan njaba jamur kanggo nutupi film plastik digawe panas ing pola lan cithakan. Ing cetakan casting bakal dadi cukup kuwat kanggo tahan logam molten sak casting. Sawise entuk jamur vakum, isi kothak wedhi karo wedhi garing tanpa Binder, lan banjur segel lumahing ndhuwur jamur wedhi karo film plastik, ngiring dening vakum kanggo nggawe wedhi tenan lan nyenyet. Sawisé iku, mbusak jamur, sijine inti wedhi, nutup jamur kanggo nggawe everthing siap kanggo pouring. Pungkasan, casting dijupuk sawise logam molten digawe adhem lan solidified.
| Casting Busa Lost vs Casting Vakum | ||
| Item | Ilang Busa Casting | Vakum Casting |
| Castings cocok | Casting ukuran cilik lan medium kanthi rongga kompleks, kayata blok mesin, tutup mesin | Casting medium lan gedhe kanthi rongga utawa ora ana rongga, kayata counterweights wesi cor, omah poros baja cor |
| Pola lan Piring | Pola busa digawe kanthi cetakan | Cithakan karo kothak nyedhot |
| Sand Box | Ngisor utawa limang sisih knalpot | Sekawan sisi knalpot utawa nganggo pipa knalpot |
| Film Plastik Kab | Tutup ndhuwur ditutupi film plastik | Kabeh sisih loro setengah saka kothak wedhi disegel dening film plastik |
| Bahan Coating | Cat adhedhasar banyu kanthi lapisan sing kandel | Cat adhedhasar alkohol kanthi lapisan tipis |
| Molding Pasir | Pasir garing kasar | Pasir garing sing alus |
| Geter Molding | 3 D Getaran | Getaran Vertikal utawa Horizontal |
| tuang | Pouring Negatif | Pouring Negatif |
| Proses Pasir | Ngilangi tekanan negatif, nguripake kothak kanggo nyelehake wedhi, lan wedhi banjur digunakake maneh | Ngilangi tekanan negatif, banjur wedhi garing tiba ing layar, lan wedhi didaur ulang |
Apa Kaluwihan saka Vacuum Casting?
1) Ingcasting vakumduwe akurasi dimensi dhuwur, outline cetha lan lumahing Gamelan.
2) Ora ana binders, banyu lan aditif ing wedhi ngecor, kang ndadekake proses wedhi prasaja.
3) Iku prasaja kanggo ngresiki castings vakum. Gas sing kurang mbebayani diasilake sajrone proses casting.
4) Casting vakum bisa digunakake ing macem-macem industri. Bisa digunakake kanggo produksi kumpulan cilik siji-potong uga produksi massal, utamané gedhe lan medium-ukuran castings lan lancip-walled castings luwih cocok kanggo casting vakum.
Apa Metals lan Alloys Bisa Casting Vacuum Casting?
• wesi Cast Gray, wesi Cast ulet
• Baja Karbon: Karbon rendah, karbon menengah lan baja karbon dhuwur
•Cast Steel Alloys: Baja paduan rendah, baja paduan tinggi, baja paduan khusus
• Aluminium lan wesi sing
• Kuningan & Tembaga.
Cast steel nuduhake baja sing digunakake kanggo nggawe casting baja. Cast baja kudu digunakake nalika kekuatan casting punika relatif dhuwur lan nggunakake wesi cast ora bisa ketemu syarat. Nanging, fluidity baja molten saka baja cast ora apik kaya wesi cast, supaya kekandelan saka struktur pouring ngirim ora cilik banget lan wangun ngirim ora rumit banget. Nalika isi silikon dikontrol ing wates ndhuwur, fluiditas baja molten bisa ditingkatake.Baja cast bisa dipérang dadi baja paduan cast lan baja karbon cast miturut komposisi kimia, lan bisa uga dipérang dadi baja alat cast, cast baja khusus, engineering lan casting struktural lan cast baja alloy miturut ciri.
Baja paduan tuang bisa dipérang dadi baja paduan rendah (total unsur campuran kurang saka utawa padha karo 5%), baja paduan tuang (elemen paduan total 5% nganti 10%) lan baja paduan dhuwur (total paduan). unsur luwih saka utawa padha 10%).
