Alloy Steel Casting by Sand Mold Casting

China OEM mwambo aloyi zitsulo chipolopolo nkhungu kuponyera mankhwala.

Kujambula kwa zipolopolondondomeko amatchedwanso pre- TACHIMATA utomoni mchenga kuponya ndondomeko, otentha chipolopolo akamaumba castings kapena pachimake kuponyera ndondomeko. Zomwe zimapangidwira kwambiri ndi mchenga wa phenolic resin, womwe umakhala wokwera mtengo kuposa mchenga wobiriwira ndi furan resin. Kuphatikiza apo, mchengawu sungagwiritsidwenso ntchito.

Ubwino wa Furan Resin Wokutidwa ndi Mchenga Wodzilimbitsa Moumitsa Wodzipangira:
1) Sinthani kulondola kwa mawonekedwe a castings ndi roughness pamwamba.
2) Kuuma kwa nkhungu (pachimake) mchenga sikufuna kuyanika, komwe kungapulumutse mphamvu, komanso matabwa otsika mtengo kapena mabokosi apulasitiki ndi ma templates angagwiritsidwenso ntchito.
3) Mchenga wodzilimbitsa wokhawokha ndi wosavuta kuphatikizika ndikugwa, zosavuta kuyeretsa zotayira, ndipo mchenga wakale ukhoza kubwezeredwa ndikugwiritsanso ntchito, zomwe zimachepetsa kwambiri kulimba kwa ntchito yopanga pachimake, kufananiza, kugwa kwa mchenga, kuyeretsa ndi maulalo ena, ndi ndikosavuta kuzindikira makina kapena makina.
4) Gawo lalikulu la utomoni mumchenga ndi 0.8% ~ 2.0% yokha, ndipo mtengo wathunthu wazopangira ndizotsika.

Chifukwa chakuti njira yodzipangira yokha ili ndi ubwino wambiri womwe watchulidwa pamwambapa, njira yodzipangira yokha siigwiritsidwa ntchito popanga pachimake, komanso imagwiritsidwa ntchito popanga kuumba. Ndizoyenera kwambiri kupanga chidutswa chimodzi ndi kupanga batch yaying'ono, ndipo zimatha kupanga chitsulo choponyedwa, chitsulo choponyedwa ndi alloy castings. Malo ena opangira zinthu ku China alowa m'malo mwa nkhungu za mchenga wouma, zoumba za mchenga wa simenti, ndikusintha pang'ono za mchenga wa magalasi amadzi.
