Qhov saum npoo zoo ntawm cov khoom siv tuag-cam khwb cia feem ntau yog txiav txim raws li qhov smoothness ntawm cov khoom plig, qhov tseeb ntawm cov ntsiab lus, tsis muaj khawb, thiab tsis muaj npuas. Cov qualities no txiav txim siab tus nqi perceived thiab aesthetic thov ntawm cov medals. Cov kev zoo no tau cuam tshuam los ntawm cov yam tseem ceeb thoob plaws hauv tag nrho cov txheej txheem tuag-casting (los ntawm kev tsim mus rau tom qab ua tiav). Ntawm no yog cov ncauj lus kom ntxaws txog qhov tseem ceeb tshaj plaws:
Kev tsim kho tsis zoo yog qhov tseem ceeb ntawm qhov tsis xws luag, vim lawv yuam cov txheej txheem tuag-casting los them rau cov yam ntxwv tsis ua haujlwm. Cov yam ntxwv tseem ceeb ntawm kev tsim qauv muaj xws li:
Medal Thickness:Cov phab ntsa tuab tsis sib xws (piv txwv li, 1mm ntug nyob ib sab ntawm 6mm logo) ua rau tsis sib xws. Thicker seem shrinks ntau raws li lawv solidify, tsim nto dab dej cim (kev nyuaj siab) los yog "pits"; thinner seem yuav txias sai heev, ua rau txias kaw (pom cov kab uas molten hlau ntws tsis ua hauj lwm zoo). Rau cov khoom plig, ib qho tuab tuab ntawm 2-4mm yog qhov zoo tshaj plaws kom tsis txhob muaj cov teeb meem no.
Draft Angles & Ntse Corners:Yog tsis muaj lub kaum sab xis txaus (1-3 ° rau feem ntau qhov khoom plig), cov hlau tsis muaj hlau nplaum nplaum rau cov pwm, ua rau muaj khawb los yog "kua kua muag" thaum demolded. Lub kaum ntse ntse 90 ° ntxiab huab cua thaum lub sij hawm casting, ua npuas huab cua (me me, puag ncig indentations) ntawm qhov chaw; rounding fab rau 0.5-1mm tshem tawm qhov teeb meem no.
Nthuav dav qhov loj & Complexity:Cov ntsiab lus zoo heev (piv txwv li, cov ntawv me dua 8pt, cov kab nyias nyias <0.3mm) tsis tuaj yeem ua tiav los ntawm cov hlau molten, ua rau qhov muag plooj lossis ploj ntaws. Txoj kev 3D ntau dhau (piv txwv li, qhov chaw sib sib zog nqus los yog qhov khoob khoob) kuj cuab cua, tsim cov voids uas mars saum npoo.
Cov pwm yog "tus qauv" rau qhov khoom plig saum npoo - txhua qhov tsis zoo ntawm cov pwm yuav raug tsom rau ntawm cov khoom kawg.
Pwm nto polishing:Cov pwm tsis zoo polished tawm ntawm qhov chaw roughness (grainy los yog tsis sib xws) ntawm cov khoom plig; ib tug heev polished pwm tsim ib tug du, reflective puag rau plating los yog enamel.
Venting System Efficiency:Tsis txaus los yog thaiv pwm vents cuab cua thaum lub sij hawm hlau txhaj tshuaj, ua rau nto npuas (pom me me, hollow me ntsis) los yog "porosity" (microscopic qhov tshwm sim dull).
Cov pwm yog "tus qauv" rau qhov khoom plig saum npoo - txhua qhov tsis zoo ntawm cov pwm yuav raug tsom rau ntawm cov khoom kawg.
Molten Hlau Kub:Yog tias qhov ntsuas kub tsawg dhau, cov pwm yuav tsis ua kom zoo. Yog tias qhov kub thiab txias dhau lawm, nws yuav ua rau oxidation thiab tsim cov khoom pov tseg, ob qho tib si yuav cuam tshuam rau qhov khoom plig zoo.
Txhaj Siab & Ceev:Tsis tshua muaj siab / ceev tiv thaiv cov hlau ua kua los ntawm kev sau cov cheeb tsam ntawm cov pwm, ua rau qhov muag tsis pom ntawm cov khoom lag luam lossis cov ntsiab lus daws tsis tiav.; Kev kub siab / ceev, nws yuav ua rau huab cua tsis zoo thiab tsim npuas, lossis cov hlau yuav txaws rau hauv pwm, ua rau cov khoom tsis sib xws ntawm qhov chaw, kev tswj hwm yog tsim nyog los xyuas kom meej qhov zoo.
Lub sijhawm txias:luv luv: Hlau solidifies unevenly, tsim deg warping (xws li, ib tug nkhaus medal ntug) los yog sab hauv kev ntxhov siab tom qab ua rau nto tawg; Ntev dhau lawm: Hlau overcools nyob rau hauv pwm, lo rau saum npoo thiab tawm khawb thaum demolded.
Daim Ntawv Thov Tso Cai Tso Tawm:Tshaj tawm tus neeg sawv cev, Tso cov nplaum nplaum, oily residue ntawm qhov khoom plig, uas tiv thaiv plating / enamel los ntawm adhering (ua rau tev lossis tawg tom qab); Tsis txaus tso tawm tus neeg sawv cev: Ua rau qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.
Xaiv high-purity alloys nrog cov khoom tsim nyog yog lub hauv paus rau kev ua kom lub ntsej muag du thiab ci ntsa iab ntawm cov khoom plig. Lub xub ntiag ntawm impurities thiab tsis raug xaiv cov khoom yuav ncaj qha ua rau cov tsos tsis xws luag.
Cov kauj ruam tom qab casting (trimming, polishing, tu) yog qhov tseem ceeb rau kev txhim kho qhov zoo
Deburring & Trimming:Tshaj-trimming txiav mus rau hauv qhov khoom plig nto, tsim cov npoo sib npaug lossis "nicks" hauv cov ntsiab lus nyem. Hauv qab-trimming yoojyim nyias hlau burrs uas xav tias ntxhib rau kov.
Cov txheej txheem polishing:Over-polishing Hnav cov ntsiab lus zoo (piv txwv li, ua cov ntawv nyeem tsis tau) lossis tsim qee qhov chaw glossy, lwm tus dull
Siv cov polish tsis raug:Coarse compounds (piv txwv li, ntawv xuab zeb <300 grit) tawm cov cim kos; low-quality rouge ua streaks ntawm plated nto.
Ntxuav ua ntej txheej:Yog hais tias polishing residue los yog roj stains tsis tau muab tshem tawm kom huv si, nws yuav ua rau cov electroplated txheej tev tawm los yog npuas nyob rau hauv lub enamel, heev cuam tshuam rau adhesion.
