Panyedhiya catings investasi kuningan adat OEM saka China karomesin CNC, perawatan permukaan lan layanan perawatan panas.
Kita bisa nyedhiyakake Sertifikat Bahan 3.1 saka logam casting miturut EN 10204 yen sampeyan butuh. Cara inspeksi sing kasedhiya: tes dimensi kanthi CMM, tes non-destruktif, komposisi kimia, sifat mekanik, tes kekerasan, keseimbangan statis, keseimbangan dinamis, tekanan udara lan tekanan banyu.
Miturut macem-macem bahan binder sing digunakake kanggo nggawe cangkang, casting investasi bisa dipérang dadi casting silika sol lan casting kaca banyu. Proses pengecoran investasi silika sol nduweni Toleransi Pengecoran Dimensi (DCT) lan Toleransi Pengecoran Geometris (GCT) sing luwih apik tinimbang proses kaca banyu. Nanging, sanajan kanthi proses casting sing padha, Kelas Toleransi bakal beda karo saben alloy cast amarga macem-macem castability. Pengecoran kita pengin ngomong karo sampeyan yen sampeyan duwe panjaluk khusus babagan toleransi sing dibutuhake. Ing ngisor iki minangka kelas toleransi umum sing bisa ditindakake kanthi cara casting silika sol lan proses casting kaca banyu kanthi kapisah:
✔ DCT Grade dening Silica Sol Lost Wax Casting: DCTG4 ~ DCTG6
✔ DCT Grade dening Water Glass Lost Wax Casting: DCTG5 ~ DCTG9
✔ GCT Grade dening Silica Sol Lost Wax Casting: GCTG3 ~ GCTG5
✔ GCT Grade dening Water Glass Lost Wax Casting: GCTG3 ~ GCTG5
Minangka wesi basis tembaga, kuningan lan tembaga bisa kawangun dadi bagean Highly Komplek, nggawe padha becik kanggoproses casting investasi. Fluktuasi biaya sing tetep bisa nggawe bahan kasebut sensitif banget, nggawe sampah larang banget, utamane nalika nimbang mesin CNC lan / utawa tempa minangka proses manufaktur kanggo ngasilake bagean casting. Tembaga murni ora biasane dibuwang. Pengecoran investasi (lilin sing ilang) minangka metode pengecoran presisi kompleks kanthi rincian bentuk jaring kanthi nggunakake replikasi pola lilin. Casting investasi utawa lilin ilang minangka proses mbentuk logam sing biasane nggunakake pola lilin sing dikubengi cangkang keramik kanggo nggawe cetakan keramik. Nalika cangkang garing, lilin dilebur, mung ninggalake jamur. Banjur komponèn casting kawangun dening pouring logam molten menyang jamur Keramik.
Kuningan minangka paduan sing kasusun saka tembaga lan seng. Kuningan sing kasusun saka tembaga lan seng diarani kuningan biasa. Yen macem-macem paduan sing kasusun saka luwih saka rong unsur, diarani kuningan khusus. Kuningan minangka paduan tembaga karo seng minangka unsur utama. Minangka isi seng mundhak, kekuatan lan plastisitas saka alloy mundhak Ngartekno, nanging sifat mechanical bakal ngurangi Ngartekno sawise ngluwihi 47%, supaya isi seng kuningan kurang saka 47%. Saliyane seng, tembaga tuang asring ngemot unsur paduan kayata silikon, mangan, aluminium, lan timbal.
Casting kuningan nduweni sifat mekanik sing luwih dhuwur tinimbang tembaga, nanging regane luwih murah tinimbang tembaga. Cast Kuningan asring digunakake kanggo tujuan umum prewangan bushes, bushings, Gir lan liyane nyandhang-tahan bagean lan klep lan bagean karat-tahan liyane. Kuningan nduweni resistensi nyandhang sing kuat. Kuningan asring digunakake kanggo nggawe katup, pipa banyu, pipa sambungan kanggo AC internal lan eksternal, lan radiator.
