Bayanin Kayayyakin Casting na Core Die

Injiniyoyin injiniyoyi dole ne su kimanta kaddarorin kayan aiki bisa dabara, daidaita tsarin aiki, ingancin farashi, da yuwuwar aiki lokacin zabar gawa na simintin gyare-gyare. A ƙasa akwai nazarin kwatancen kayan masana'antu:

1.Aluminum Alloys (Kasuwanci Mai Girma)

Mahimman Masana'antu: Motoci, Aerospace, Lantarki na Mabukaci, Kera Babura.
Amfanin Gasa:
- Zane mai sauƙi: Ƙirar ≈1/3 na Fe / Cu / Zn; ƙaƙƙarfan ƙarfi-da-nauyi rabo.
- Thermal & Kayan Wutar Lantarki ***: Mafi dacewa don zubar da zafi da abubuwan lantarki.
- Juriya na Lalata: Layer alumina mai ɗaukar kansa yana tabbatar da dorewa a cikin mahallin oxidative.
- Ingantaccen Tsari: Maɗaukakin simintin gyare-gyare, iya aiki, da aikin injina a kan iyakar zafin jiki (-269°C zuwa 300°C).
Bayanan Ayyuka:
* Rage raguwar porosity ta hanyar ingantaccen ƙarfi mai sarrafawa.
* Injin ɗakin sanyi an ba da shawarar don magance haɗarin alaƙar ƙarfe.

2.Zinc Alloys (Maganin Ƙimar Ƙirar Ƙarfafa Ƙarfafa)

Maɓallin Aikace-aikace: Hardware, Makullai, Lantarki na Bakin Baƙi, Kayan Ado.
Ƙimar Ƙimar:
- Babban Madaidaici a Sikeli: Ƙananan narkewa (385°C) yana ba da damar hadaddun geometries tare da ± 0.05mm haƙuri.
- Forceper farfajiya kyau: a matsayin-cast kayan cin 0.8μm; masu jituwa tare da duk matakan ƙarewa.
- Ƙimar Tattalin Arziƙi: 20-30% ƙananan farashin kayan aiki vs. aluminum.
Matsalolin Mahimmanci:
* Hankalin zafin jiki: kewayon aiki -10°C zuwa 100°C.
* Ƙuntataccen kulawar ƙazanta (Pb/Cd/Sn

3.Magnesium Alloys (Innovation mai nauyi mai nauyi na gaba)

Matsayin Dabaru:
- Jagoran Rage Nauyi: 33% ya fi nauyi fiye da aluminum; 75% vs karfe.
- Damping Vibration: 30% mafi girma shawar makamashi vs. aluminum don aikace-aikacen NVH mai hankali.
- Dorewa: Cikakken sake yin amfani da shi ya yi daidai da umarnin ESG.
Jagororin Aiwatarwa:
* Jiyya na tilas (anodizing/plating) don kariya ta lalata.
* Yana buƙatar kulawa ta musamman saboda haɗarin pyrophoric yayin injina.

Kalubalen samarwa & Dabarun Ragewa

Shawarar Fasaha
1. Bore Machining Limitation (Al-Si Alloys):
Kiyaye 0.2-0.9mm hypereutectic Si Layer mai mahimmanci don ɗaukar saman. Yin aiki fiye da kima yana rage rayuwar sabis da 60-70%.

2. Ka'idojin Gudanar da Zazzabi:
- Magnesium: Kula da mold ΔT ≤15°C ta hanyar tashoshi masu sanyaya.
- Zinc: Aiwatar da zafin T6 (100°C/4h) bayan simintin gyare-gyare don daidaita girma.

3. Yarda da Ka'ida:
- IATF 16949: 2016 buƙatun don abubuwan haɗin zinc na mota.
- Yarda da DFARS don aikace-aikacen magnesium na sararin samaniya.

Ingantattun zaɓin kayan da aka haɗa tare da rufaffiyar tsarin sarrafawa na iya cimma:
- Rage lokacin sake zagayowar 15-20%.
- 30% rage yawan raguwa
- ROI-watanni 12 akan ci gaba da saka hannun jari na kayan aiki

Don ƙirar ƙirar ROI na musamman ko shawarwarin DFM, tuntuɓi ƙungiyar masu ba da shawara ta fasaha.
