Qhov txawv ntawm yog dab tsiTuag Castingthiab Investment Casting?
Lawv yog ob txoj kev tsim khoom siv rau cov khoom siv hlau uas muaj qee qhov sib xws tab sis muaj qhov sib txawv:
1. Pwm khoom - Hlau tuag vs. ceramic peev plhaub
- Tuag Cast siv reusable steel pwm muaj peev xwm ntau txhiab lub voj voog
- Kev nqis peev casting siv cov khoom siv pov tseg ceramic uas yuav tsum tau tawg tom qab txhua qhov casting
2. Ntau lawm ntim - Siab vs. qis
- Tuag Cast muaj txiaj ntsig zoo rau ntau txhiab mus rau lab tus castings hauv ib xyoos
- Kev nqis peev casting feem ntau ua rau 50-5000 daim ib xyoos
3. Tus nqi hauv paus - Cov nqi teeb tsa siab vs. tus nqi qis dua
- Tuag Cast muaj tus nqi pib siv ntau heev tab sis qis dua ib feem ntawm tus nqi ntawm ntim
- Kev nqis peev casting muaj cov nqi pwm qis dua tab sis siab dua rau ib daim nqi
4. Hlau quab yuam - Kev txhaj tshuaj siab tiv thaiv lub ntiajteb txawj nqus
- Tuag Cast txhaj hlau ntawm qhov siab siab txog 30, 000 psi
- Kev nqis peev casting cia siab rau lub ntiajteb txawj nqus los sau cov pwm ceramic
5. Geometries - Nyias phab ntsa vs. unlimited contours
- Tuag Cast tuaj yeem ua kom nyias nyias mus rau 0.004 ntiv tes
- Kev nqis peev tuaj yeem daws cov teeb meem nyuaj, sab hauv geometry yam tsis muaj kev txwv tsim
6. Tolerances - Zoo heev vs. nruab nrab
- Tuag Cast tuav +/- 0.002 nti qhov ntev kam rau ua
- Kev nqis peev casting feem ntau tuav +/- 0.02 nti kam rau ua
7. Tiav - Zoo heev vs. nruab nrab
- Tuag Cast ua kom zoo nto tiav nyob ib ncig ntawm 64 Ra microinches
- Kev nqis peev casting muaj coarser ~ 250 Ra microinch tiav
Kev nkag siab txog qhov sib txawv tseem ceeb no tso cai rau xaiv cov txheej txheem zoo tshaj plaws rau daim ntawv thov raws li kev xav tau thiab kev tsim khoom.
Zinc yog dab tsiTuag Casting?
ZincTuag Castingyog hais txog kev tsim cov zinc alloy castings uas siv cov pwm tuaj yeem siv tau, piv txwv li tuag. Piv rau lwm cov alloys xws li txhuas lossis magnesium, zinc muaj qee qhov txiaj ntsig tshwj xeeb:
- Exceptional fluidity thaum molten, sau nyias hla ntu nrog yooj yim
- Tsawg melting point ntawm 780 degree F ua kom lub sij hawm voj voog sai
-Qhov siab qhov tseeb thiab ruaj khov hauv kev pabcuam
- Cov khoom siv raug nqi piv rau txhuas lossis magnesium
- Tsawg kawg tom qab casting machining yuav tsum tau
- Yooj yim platability rau corrosion kuj thiab zoo nkauj
Txawm li cas los xij, zinc kuj muaj qee qhov kev txwv piv rau lwm cov alloys:
- Tsawg zog dua aluminium lossis magnesium alloys
- Txwv kub tsis kam, tuaj yeem nkag mus rau hauv load ntawm 120 degree
- Ntau reactive thiab tuaj yeem ua kom tuag steel thaum lub sijhawm
Feem ntau zinc Casting alloys muaj xws li:
- Zamak 3 alloy (Zn-4Al): feem ntau siv, zoo heev zog thiab ductility
- Zinc 2 alloy (Zn-2Cu): zinc alloy lub zog siab tshaj plaws, siv rau kev siv siab hnav
- Zinc 5 alloy (Zn-5Al): kev ua tau zoo dua, tuaj yeem ua chrome plated
