Dab tsi txhais tau qhov siab -} Cov iav zoo iav? Lub luag haujlwm ntawm cov pwm-hom, cov ntaub ntawv, thiab ntau dua
Nov 08, 2025
Tso lus
Iav Stampshades muab cov paj ntaub thiab kev ua haujlwm zoo, thiab lawv cov khoom siv tseem ceeb, thiab lawv cov khoom lag luam tseem ceeb, kev txiav txim siab cov khoom kawg, meej pem. Cov kab lus no qhia txog cov kev lag luam tseem ceeb hauv cov pwm, cov qauv no, cov ntaub ntawv, kev kho cov nplaim, thiab tiam sis.
Cov Hom Iav Laughade Pwm
Cov pwm feem ntau yog cov qauv hloov pauv thiab cov yam ntxwv siv tau: Nyob pwm thiab tsau pwm.
Nyob pwm pwm Excel nyob rau hauv kev tsim cov pob los sis}}}} Cov iav Statshades (piv txwv li, spheralic, lossis tusyees curved tsim). Nruab nrog cov khoom siv tsis muaj retacentable lossis lawv cia cov iav cov khoom tig thaum lub ntsej muag ua kom zoo nkauj ua kom pom cov kab noj hniav me me, tsis txhob muaj qhov tsis xws luag zoo li tsis sib xws. Lawv zoo -} ruited rau nruab nrab ntawm cov teeb meem zoo nkauj uas muaj qhov sib xws rau cov khoom lag luam hauv phab ntsa thiab cov nqi kho.
Moulds tsau, yog tsim rau cov qauv ua kom zoo nkauj (piv txwv li cov qauv asymmetical, sab hauv kev tawm tsam, lossis cov npoo tsis muaj). Cov khoom lag luam tsis tuaj yeem tig hauv cov pwm ua ke, tsis yog - Cov kab tsuag kho tau yooj yim, raws li kev sib hloov yuav ua rau muaj kev puas tsuaj rau kev tsim. Ib qho tseem ceeb ua ntej - Ntau cov pwm ua kom ruaj khov rau ob peb teev yog txhaj thiab ua kom muaj cov qauv zoo ntawm cov qauv sib txawv. Moulds tsau qis dua yooj yim rau cov qauv hloov tab sis xa cov teeb meem siab rau kev cai lossis kev ua yeeb yam teeb meem.
Cov ntaub ntawv ntawm iav teeb pom kev
Pwm cov ntaub ntawv yuav tsum tiv thaiv 1500℃molten iav thiab cua sov.
Cov hlau cam khwb cia, cov tsoos thiab tus nqi -}}}}}} pa thermal conductivity (2-4% carbon) rau cov cua sov. Grey cam khwb cia hlau (Fig Graphite) haum cov pwm yooj yim; Ntiav hlau (kheej kheej graphite) ntawm cov duab ua txiab. Nws yog nkig, tab sis, thiab tsis tshua meej dua li cov hlau.
Cov pwm hlau (qis dua 2% carbon) muab lub zog zoo dua thiab prefision. Kub - Ua haujlwm tuag Hlau (H13, 1.2344) Tsis kam ua rau muaj kev nkees rau cov pwm; Stainless hlau (304/316) Kev nyiam huv siliene -} umented xav tau. Lawv raug nqi ntau dua thiab muaj qis dua thermal conductivity.
Cov ntaub ntawv tshwj xeeb xws li Graphite (cov qauv siab, kim) thiab cov qauv siv hluav taws xob, cov khoom siv tsis zoo rau cov neeg me me lossis cov duab kos duab.
Kev kho cov npoo npoo
Cov kev kho deg cov kev kho mob los txhawb, zoo, thiab lub neej pwm.
Mould Hmoov (Tso Tus Sawv Cev) yog qhov tseem ceeb: Nws txwv tsis pub cov kua muag cua sov (nyias khaubncaws sab nraud povtseg Graphite - Raws hmoov ua haujlwm rau cam khwb cia hlau; Ceramic - Raws li cov hlau.
Lwm yam kev kho mob suav nrog Nitrividing (Hardens nto rau hnav) thiab polishing (iav tiav rau pob tshab stucksades). Etching tsim textures, nrog hmoov tiv thaiv cov qauv.
Iav cov iav pwm yog qhov tseem ceeb rau kev tsim teeb pom kev tsim khoom. Nyob / Tuav Pwm thiab nrum hlau / steel cov ntaub ntawv sib ntsib ntawm kev xav tau, thaum kev kho mob txhim kho kev ua tau zoo. Yav tom ntej sib txawv ntawm kev hloov kho tshiab thiab muaj kev ruaj khov, ua qhov kev paub no rau cov kws tshaj lij kev sib tw ua kev sib tw.
