Xitoy OEM tomonidan tayyorlangan zanglamaydigan po'latdan yasalgan pervanelyo'qolgan mum sarmoyasini quyish jarayoni.
Har qanday nikel asosli yoki zanglamaydigan po'latdan yasalgan quyma qotishma elementlari xrom, nikel va molibdendir (yoki "moli"). Ushbu uchta komponent quymaning don tuzilishi va mexanik xususiyatlarini aniqlaydi va quyma issiqlik, aşınma va korroziyaga qarshi kurashish qobiliyatida muhim rol o'ynaydi.
Zanglamaydigan po'latdan minimal xrom miqdori 10,5% ni tashkil qiladi, bu uni korroziy suyuqlik muhitiga va oksidlanishga chidamli qiladi. Biroq, bu mutlaq emas. Zanglamaydigan po'latdan investitsiyaquyma buyumlar suyuq muhitda va 1200 ° F (650 ° C) dan past bo'lgan bug'larda ishlatilganda "korroziyaga chidamli" va bu haroratdan yuqori foydalanilganda "issiqlikka chidamli".
Investitsion quyma komponentlarning afzalliklari:
- Zo'r va silliq sirt qoplamasi
- Qattiq o'lchamli toleranslar.
- Dizayn moslashuvchanligi bilan murakkab va murakkab shakllar
- Yupqa devorlarni quyish qobiliyati, shuning uchun engilroq quyma komponent
- quyma metallar va qotishmalarning keng tanlovi (qora va rangli)
- Qoliplar dizaynida qoralama talab qilinmaydi.
- Ikkilamchi ishlov berishga ehtiyojni kamaytirish.
- Kam moddiy chiqindilar.
