Ushbu maqolada kulrang cho‘yandan yuqori konstruksion, yupqa devorli quyma mahsulotlar olishda yonuvchi modeldan foydalanish texnologiyasi tadqiq etilgan. Tadqiqot ishida sifatli quyma mahsulotlarini uchun yonuvchan modellardan foydalanish texnologiyasi takomillashtirilga. Yonuvchi model sifatida foydalaniladigan materialning xususiyatlari, modelning o‘lcham aniqligi va sirt holatining quyma mahsulot sifatiga ta’siri tahlil qilingan. Shuningdek, modelni maxsus qoplama bilan tayyorlash hamda suyuq kulrang cho‘yan bilan o‘zaro ta’sirlashish jarayonida modelning parchalanish xususiyatlari ko‘rib chiqilgan. Tadqiqot davomida tayyor quyma mahsulotlarni olishda yuzaga kelishi mumkin bo‘lgan gazli nuqsonlar, suyuq qotishmaning qolip bo‘shlig‘ini to‘ldirishi hamda quyma sifatiga ta’sir etuvchi asosiy omillar aniqlangan. Olingan natijalar asosida yonuvchi modellardan unumli foydalanishning optimal texnologiyasi asosida kulrang cho‘yandan olinadigan quyma mahsulotlarining sifatini yaxshilash imkoniyatlarini ko‘rsatadi. Tadqiqot natijalari murakkab shaklli, yuqori konstruksion, yupqa devorli detallarini kulrang cho‘yan qotishmasidan kam miqdordagi mexanik ishlov bilan ishlab chiqarish texnologiyasini takomillashtirishda amaliy ahamiyatga ega.
