Shell Mould Casting Foundry
Shell ngecor casting uga disebut wis ditutupi resin wedhi casting proses, panas shell ngecor casting utawa inti proses casting. Bahan cetakan utama yaiku pasir resin fenolik sing wis dilapisi, sing luwih larang tinimbangwedhi ijolan wedhi resin furan. Kajaba iku, wedhi iki ora bisa didaur ulang.
Komponen casting cangkang ngecor duwe biaya sing luwih dhuwur tinimbangpengecoran pasir. Nanging, ingbagean casting ngecor cangkangduwe akeh kaluwihan kayata toleransi dimensi kenceng, kualitas lumahing apik lan kurang casting cacat.
Sadurunge nggawe cetakan lan inti, wedhi sing dilapisi wis ditutupi film resin padhet ing permukaan partikel pasir. Pasir sing dilapisi uga diarani wedhi cangkang (inti). Proses teknologi yaiku nyampurake wit fenolik thermosetting bubuk kanthi mekanis karo wedhi mentah lan ngalangi nalika digawe panas. Wis dikembangake dadi pasir sing dilapisi kanthi nggunakake resin fenolik termoplastik plus agen curing laten (kayata urotropine) lan pelumas (kayata kalsium stearat) liwat proses lapisan tartamtu.
Nalika pasir sing dilapisi dipanasake, resin sing dilapisi ing permukaan partikel pasir lebur. Ing tumindak klompok methylene decomposed dening Maltropine, resin molten kanthi cepet ngowahi saka struktur linear kanggo struktur awak infusible supaya wedhi ditutupi solidified lan kawangun. Saliyane ing wangun granular garing umum saka wedhi dilapisi, ana uga wedhi dilapisi teles lan kenthel.
Sawise nyampur wedhi asli (utawa wedhi direklamasi), resin Cairan lan katalis Cairan roto-roto, lan isi menyang kothak inti (utawa kothak wedhi), lan banjur ngencengi kanggo harden menyang jamur utawa jamur ing kothak inti (utawa kothak wedhi). ) ing suhu kamar, cetakan casting utawa inti casting dibentuk, sing diarani modeling kothak inti kadhemen (inti), utawa metode hardening (inti). Metode self-hardening bisa dipérang dadi resin furan katalis asam lan metode self-hardening wedhi resin fenolik, metode self-hardening wedhi resin urethane lan metode self-hardening monoester fenolik.

Shell Mold Casting Langkah
✔ Nggawe Pola Logam.Wedhi resin sing wis dilapisi kudu dipanasake ing pola kasebut, mula pola logam minangka alat sing dibutuhake kanggo nggawe cetakan cetakan cangkang.
✔ Nggawe Cetakan Pasir Pra-dilapisi.Sawise nginstall pola logam ing mesin ngecor, wedhi resin wis ditutupi bakal dijupuk menyang pola, lan sawise dadi panas, lapisan resin bakal molten, banjur cetakan wedhi dadi cangkang wedhi ngalangi lan intine.
✔ Leleh Cast Metal.Nggunakake tungku induksi, bahan kasebut bakal dilebur dadi cairan, banjur komposisi kimia wesi cair kudu dianalisis kanggo cocog karo nomer lan persen sing dibutuhake.
✔ Tuang Logam.Nalika wesi ilang ketemu syarat, banjur bakal diwutahake menyang cetakan Nihan. Adhedhasar karakter sing beda saka desain casting, cetakan cangkang bakal dikubur ing pasir ijo utawa ditumpuk kanthi lapisan.
✔ Shot Blasting, Grinding lan Cleaning.Sawise cooling lan solidification saka casting, risers, gerbang utawa wesi tambahan kudu Cut mati lan dibusak. Banjur casting wesi bakal di resiki dening peralatan sand peening utawa mesin shot blasting. Sawise mecah sirah gating lan garis parting, bagean casting rampung bakal teka, nunggu pangolahan luwih yen perlu.

Kaluwihan saka Shell Mould Casting
1) Wis kinerja kekuatan cocok. Bisa nyukupi syarat kanggo wedhi inti cangkang kanthi kekuatan dhuwur, wedhi kothak panas medium-kekuatan, lan wedhi paduan non-ferrous sing kurang kekuatan.
2) fluidity banget, moldability apik saka inti wedhi lan outline cetha, kang bisa gawé intine wedhi paling Komplek, kayata intine wedhi jaket banyu kayata sirah silinder lan awak mesin.
3) Kualitas permukaan inti pasir apik, kompak lan ora longgar. Sanajan kurang utawa ora ana lapisan sing ditrapake, kualitas permukaan sing luwih apik bisa dipikolehi. Akurasi dimensi coran bisa tekan kelas CT 7 - CT 8, lan kekasaran permukaan Ra bisa tekan 6,3 - 12,5 μm.
4) Good collapsibility, kang kondusif kanggo casting reresik lan Ngapikake kinerja produk
5) Inti wedhi ora gampang nyerep kelembapan, lan kekuwatan panyimpenan jangka panjang ora gampang dikurangi, sing cocog kanggo panyimpenan, transportasi lan panggunaan
