Aluminium Sand Foundry

Tsawg-pressure casting ntawm txhuas casting yog ib txoj kev casting uas tso cai rau cov kua alloy los sau cov pwm kab noj hniav nyob rau hauv siab thiab solidify nyob rau hauv siab kom tau ib tug casting. Lub hauv paus ntsiab lus tseem ceeb yog qhia cov cua compressed rau hauv lub qhov cub kaw los yog lub qhov cub hluav taws kub, kom cov hlau molten nce raws cov riser nyob rau hauv siab, nkag mus rau hauv pwm kab noj hniav smoothly ntawm lub rooj vag, thiab tswj cov roj siab ntawm cov kua dej kom txog thaum lub casting yog kiag li solidified.

Txheej txheem ntawm Low-Pressure Casting ntawm Aluminium Casting

1. Cawv Rising Stage : Cov cua qhuav compressed yog nkag rau hauv lub qhov cub kaw, thiab cov hlau molten nce raws tus riser nyob rau hauv qhov kev txiav txim ntawm roj siab.

2. Pwm Filling Stage : Cov hlau molten nkag mus rau hauv lub pwm kab noj hniav kom zoo los ntawm lub rooj vag, thiab cov roj siab ntawm cov kua dej hauv lub crucible yog khaws cia.

3. Pressurized Crystallization Solidification Stage ​: Txuas ntxiv tswj cov roj siab kom txog thaum lub casting yog tag nrho solidified.

4. Decompression txias theem: Tso cov roj siab rau ntawm cov kua dej, kom cov kua hlau tsis muaj zog hauv cov riser thiab cov neeg khiav dej num ntws rov qab mus rau lub crucible los ntawm nws tus kheej qhov hnyav, ces qhib lub pwm thiab tshem tawm cov casting.

Cov yam ntxwv thiab kev siv ntawm cov khoom siv hluav taws xob tsawg ntawm cov cam khwb cia txhuas

Nta:

Smooth filling: Vim qhov tsis tshua muaj siab, muaj qhov tsis xws luag xws li pores thiab slag inclusions thaum lub sij hawm txhaws.
Dense castings: Cov castings muaj cov qauv ntom ntom thiab cov khoom siv tshuab siab.
Smooth nto: Lub peev xwm ua kom muaj zog yog qhov tsim nyog rau kev tsim cov castings nrog cov contours meej thiab du nto.

Daim ntawv thov:

Feem ntau siv nyob rau hauv aluminium alloy log manufacturing kev lag luam, thiab lwm yam.
