Visual Inspection
Kuongorora kwekuona ndiyo yekutanga uye yakatwasuka nzira yekudzora kwemhando yecastings. Inosanganisira kunyatsoongorora kwenzvimbo yekukanda kuona chero hurema hunooneka hwakadai se:
Surface Cracks:Zvidiki zvidiki pamusoro zvinogona kuratidza kushushikana kwemukati kana kutonhora zvisina kunaka.
Porosity:Kuvapo kwemaburi madiki kana voids nekuda kwegasi rakavharirwa panguva yekukanda.
Misruns:Nzvimbo umo simbi yakanyungudutswa haina kuzadza mold zvachose.
Kushata Kwepamusoro:Mamiriro enzvimbo yekukanda, iyo inofanirwa kusangana nemiyero yakatarwa yekushandiswa kwakarongwa.
Kuongorora kwemaziso kunowanzoitwa nemaoko nevanoongorora vakadzidziswa vachishandisa maturusi ekukudza magirazi kana maikorosikopu kuti vaonekwe kwezvirema zvidiki.
Internal Quality Testing
Kuve nechokwadi chemukati wemhando yekukanda, nzira dzinoverengeka dzinoshandiswa kuona zvirema zvepasi pasi izvo zvisingaonekwe nemeso. Nzira idzi dzinosanganisira:
X-Ray radiography:Iyi nzira inoshandisa X-rays kuti ibudise mifananidzo yemukati wekukanda. Inonyanya kushanda pakuona mukati mekuputika, porosity, uye inclusions.
Ultrasonic Testing (UT):Ultrasonic masaisai anofambiswa kuburikidza nekukanda, uye iwo maratidziro anoongororwa kuti aone chero mukati discontinuities kana kukanganisa.
Computed Tomography (CT) kuongorora: Chimiro chepamusoro che X-ray radiography inopa mufananidzo we 3D wekukanda, inobvumira kuongororwa kwakadzama kwezvinhu zvemukati.
Nzira dzekuongorora kunaka kweInvestment castingskazhinji zvinosanganisira: Dimensional Inspection,X-Ray Radiography uye CT Scanning.
Kuyedzwa Kusina Kuparadza (NDT)
Nzira dzisiri dzekuparadza dzekuyedza dzakakosha pakuongorora kunaka kwekukanda pasina kukuvadza zvikamu. Inonyanya kuzivikanwa nzira dzeNDT dzinosanganisira:
Magnetic Particle Testing (MPT): Iyi nzira inosanganisira magnetizing kukanda uye kushandisa ferrous particles kumusoro. Chero hurema hwepamusoro kana hwepedyo-hwepamusoro huchaita kuti zvimedu zviungane, zvichiita kuti zvionekwe pasi pechiedza che ultraviolet.
Dye Penetrant Testing (DPT): Dhayi yemvura inoshandiswa pamusoro pekukanda. Mushure menguva yakatarwa yekugara, dhayi yakawandisa inobviswa, uye mugadziri anoshandiswa. Chero kukanganisa kuchaita kuti dhayi ibude kunze, ichiratidza zvikanganiso.
Eddy Current Testing (ECT): Iyi nzira inoshandisa electromagnetic induction kuona pamusoro uye padhuze-yepamusoro-yakakanganisika mune conductive zvinhu.
Zvishandiso uye Dzinoenderana Nekuongorora Nzira
Mhando dzakasiyana dzekukanda dzinoda nzira dzekutarisa dzakananga zvichienderana nekushandisa kwavo uye zvinhu zvenyama. Heino mienzaniso mishoma:
Automotive Components: Zvikamu zvakakosha senge mabhuroko einjini, silinda misoro, uye zvinomisikidzwa zvinogara zvichiongororwa uchishandisa X-ray radiography uye ultrasonic bvunzo kuti vaone kuti vanogona kutsungirira kushushikana kwekushanda.
Zvikamu zveAerospace: Nekuda kwezvakaomesesa zvekuchengetedza zvinodiwa, aerospace castings inoongororwa zvakasimba uchishandisa CT scanning uye ultrasonic bvunzo kuti ive nechokwadi chepamusoro chekuvimbika uye kuvimbika.
