China OEM custom baja karbon casting deningilang casting investasi lilinlan mesin tliti CNC.
Paduan karbon iku klompok wesi-karbon wesi karo langka unsur kimia liyane kayata Si, Mn, P lan S. Miturut tingkat isi karbon, baja karbon kanggo casting umume dipérang dadi baja karbon kurang, baja karbon medium lan baja karbon dhuwur. Baja karbon cast ing kabeh negara ing donya umume diklasifikasikake miturut kekuwatane, lan dirumusake tingkat sing cocog.
Babagan komposisi kimia baja karbon, kajaba fosfor lan belerang, ora ana watesan utawa mung watesan ndhuwur ing unsur kimia liyane. Ing premis ing ndhuwur, komposisi kimia baja karbon cast ditemtokake dening pengecoran miturut sifat mekanik sing dibutuhake.
Cara perawatan panas sakacasting baja karbonbiasane anil, normalisasi utawa normalisasi + tempering. Kanggo sawetara casting baja karbon dhuwur, quenching lan tempering uga bisa digunakake, yaiku, quenching + tempering suhu dhuwur, supaya bisa nambah sifat mechanical lengkap saka casting baja karbon. Castings baja karbon cilik bisa langsung quenched lan tempered saka negara minangka-cast. Kanggo casting baja karbon ukuran gedhe utawa Komplek-shaped, iku cocok kanggo nindakake quenching lan tempering perawatan sawise normalizing perawatan.
Kaluwihan saka Casting Investasi:
✔ Rampung permukaan sing apik lan alus
✔ Toleransi dimensi sing ketat.
✔ Wangun sing rumit lan rumit kanthi keluwesan desain
✔ Kemampuan kanggo nyithak tembok tipis mulane dadi komponen casting sing luwih entheng
✔ Pilihan saka logam tuang lan wesi (ferrous lan non-ferrous)
✔ Draft ora dibutuhake ing desain cetakan.
✔ Ngurangi kabutuhanmesin sekunder.
✔ Sampah bahan sing sithik.

Langkah-langkah Proses Casting Investasi:
Sajrone proses casting investasi, pola lilin dilapisi karo bahan keramik, sing, nalika hardened, nganggo geometri internal saka casting sing dikarepake. Umume kasus, pirang-pirang bagean dibuwang kanggo efisiensi dhuwur kanthi nempelake pola lilin individu menyang tongkat lilin tengah sing diarani sprue. Lilin dilebur saka pola - mulane uga dikenal minangka proses lilin sing ilang - lan logam molten diwutahake menyang rongga. Nalika logam solidifies, jamur Keramik wis shaken mati, ninggalake wangun net cedhak casting dikarepake, ngiring dening pagawean, testing lan packaging.
