Yakarasika wakisi yekukanda kit harisi rimwe bhokisi rehunyanzvi-ndiro bhiriji rekutanga pakati pekudhirowa pfungwa uye kubata mhete yesimbi yakapera muruoko rwako. Takaona vanotanga vachivhura makiti aya vachitarisira mashiripiti, vongoisa pasi yavo yechitatu yakakundikana modhi yewakisi na2 mangwanani, tichishamisika kuti sei sprue yakatsemuka, nei mold yakatsemuka, kana nei sirivha yakaramba kuyerera. Kushungurudzika ikoko kunoperera pano. Iyi haisi dzidziso. Ndizvo zvatakaona pamativi makumi mana nemanomwe ezviratidziro nevadzidzi vekugadzira zvishongo, mahobbyists, uye micro-studio vanovamba-nguva yega yega tichinatsa chiyero pakati pekuwanikwa uye kuvimbika kwesimbi.
Sei "Mutanga" Zvisingareve "Kukanganisa"
A chokwadi kit yekukanda wakisi yakarasika kune vatsva vanofanira kugadzirisa matambudziko matatu asingakurukurirwe: kupisa kutyisa kuramba mukudyara, kufanofungidzira kutsva maitiro ewakisi, uye kugadzikana kwedimensional kuburikidza nekutonhodza. Makitsi mazhinji anosvetuka zvinyorwa zvemapepa zvachose - kunyora "plaster-based investment" pasina kutsanangura ASTM C22 kana ISO 6872 kutevedzera. Yedu inodaro. Iyo refractory powder inosangana ne ISO 6872 Rudzi IV, ine simba rakasvibirira re ≥12 MPa uye kuwedzera kwekushisa ≤0.15% pa700 ° C. Nhamba iyoyo ine basa: ndiwo mutsauko uripo pakati pegomba rakachena uye mold yakamonyoroka inoteya mabhuru emhepo padyo nebezel.
Takaedza maumbirwo matanhatu ewakisi padivi nepadivi. Mawakisi akajairika akapfaviswa ari pasi pe45°C—haasati anyatsogadzikana kuti akwanise kutsanangura. Iyo kit inoshandisa proprietary musanganiswa ne58% nyuchi, 32% carnauba, uye 10% dammar resin-inonyunguduka zvakanyanya pa63 ° C, inobata mitsetse yakanaka pasi pe0.3 mm, uye ichipisa zvakachena pa650 ° C isina carbon residue. Iwe unozoona izvi kana iwe uchitsemura vhura furasiki yako yekutanga: hapana dema soot inonamatira kune sirivheri pamusoro, hapana chikonzero chehasha chekunhonga.
Chii chiri Mukati-uye Chisina Kuvanzwa muKudhinda Kwakanaka
Iri harisi bhokisi rezvivimbiso zvisina kujeka. Chese chikamu chinoita basa rakasimbiswa:
- Maturusi ekuveza wakisi (5-zvidimbu): Carbide-tipped, kwete Stainless simbi-nekuti matipi akapfava anokanganisa pawakisi yakaoma, zvichikonzera mavanga ekutaura anoteedzera mukukanda kwako kwekupedzisira.
- Upfu hwekudyara (1 kg): Pre-yakasanganiswa, pre-seed, mwando-inodzorwa kusvika ± 0.5% RH-hapana kufungidzira kusanganisa kusanganisa; ingoisa mvura yakadirwa pa22°C
- Vacuum flask (2L): Borosilicate girazi muviri une silicone gasket yakayerwa kusvika 90 kPa-yakakosha kubvisa mweya wakavharirwa kubva kune akaomarara mafomu
- Burnout kiln ramp profile: Pre-programmed 3-stage cycle (kuomesa → dewaxing → sintering) yakaratidza kubvisa kushushikana kwekupisa kwekutyoka mumaflask
- Crucible & tongs: Silicon carbide-lined, yakarongerwa 1100 ° C-inobata sterling sirivheri, ndarira, uye bhuronzi isina leaching iron inosvibisa.
Usipo? "Silver ingot yekutanga." Kugona. Sirivha yakachena inonyunguduka pa961°C—asi vanotanga havawanzowana tembiricha yekudira iri pasi pe1050°C. Pasina chaiyo pyrometry, vanowana porosity kana kutonhora kuvhara. Pane kudaro, kit inosanganisira calibrated copper test ingots. Master fluidity uye mold zadza nemhangura kutanga. Wobva wawedzera.
Iyo Chaiyo Bottleneck Haisi Hunyanzvi-Iyo Maitiro Kujeka
Vamwe vanogona kupokana kuti dhijitari ye3D inodhinda inoita yakarasika wakisi kusashanda. Asi hezvino izvo zvatakayera mumashandisirwo chaiwo estudio: Pamaringi ari pasi pe saizi 8 ane asymmetrical profiles, 3D-yakadhindwa resin mapatani inoda 37% yakawanda post-cast faira pane yakavezwa nemaoko wax. Sei? Resin's 0.05 mm layer mitsara inogadzira madiki-mareji anobata macompound ekupukuta, achimanikidza nguva refu yekubhavha uye kurasika kwesimbi kwepamusoro.
Kuveza nemaoko kunodzidzisa chiyero, kugovera uremu, uye nzvimbo isina kunaka intuition-unyanzvi hapana slicer software inodzokorora. Uye kana modhi yekutanga yemudzidzi ikadonha panguva yekuneta, vanodzidza nezve wax-to-flask madziro ukobvu ratios (zvishoma 6 mm), kwete chete kurova "kudhinda." Iyo tactile mhinduro loop haidzoreki. Isu takavaka bhuku rekuraira pamusoro pekutadza modes-kwete matanho. Peji 12 haina kuti "batanidza sprue." Inoti: "Kana sprue yako yakatsemuka panguva yekuzadza furasiki, tarisa tembiricha yewakisi (inofanira kunge iri > 50 ° C) uye dhayamita yesprue (≥2.5 mm yemhete)."
Kubva paBhorasiki Yokutanga kuenda kune Zvishongo Zvinoshanda—Hapana Kuchengeta Gedhi
Izvi kit yekukanda wakisi yakarasika inotora zero isati yawana ruzivo-asi zero kushivirira kune mapfupi. Inosanganisira calibrated hygrometer nekuti humidity pamusoro pe60% RH inokonzera investment slurry kuseta nekukasira, kuteya mweya. Inotakura ne 0.01 mm dial caliper-kwete seumbozha, asi nekuti mhete shank ukobvu pasi pe 1.2 mm inotadza kuyedza kumisikidza pa120 N. Idzo nhamba hadzisi dzehutongi. Iwo anotorwa kubva kuASTM F2590 (zvishongo zvekusimba mayero) uye akasimbiswa mune yedu ISO 9001-yakasimbiswa nzvimbo muQingdao-kwatinokanda dzimba dzepombi dzemarig emafuta ekumahombekombe tichishandisa yakafanana kemisitiri yekudyara uye vacuum protocol.
Iwe hausi kutenga hobby kit. Iwe uri kuwana maindasitiri-giredhi maitiro ekuranga, akaderedzwa pasi pasina dilution. Iwo akafanana cobalt-alloy nozzles isu isu muchina wehydraulic masisitimu anovimba neamwechete kupisa kwekuwedzera kudzora, yakafanana binder burnout kinetics, yakafanana mold kutendeseka logic. Precision haina kuchengeterwa zvibvumirano zvemamiriyoni emadhora. Inotanga apo wakisi yako inosangana nekudyara.
Tanga newakisi. Remekedza kupisa kwekupisa. Vimba vacuum. Kanda mhete yako yekutanga-kwete sekudzidzira, asi sehumbowo hwekuti kutonga kunotanga nguva refu simbi isati yayerera.
