چکیده

فرایند تزریق پلاستیک به دلیل هزینه کم و کارایی بالا برای تولید انبوه قطعات پیچیده کاربردی است. در این فرایند، عیوب سوختگی و پرنشدن قالب در قطعه تولیدشده، اولین عامل اثرگذار در ردشدن یا قبول آن از نظر اپراتور است. در این پژوهش، قطعه بوشن 63 از جنس یوپی‌وی‌سی، مورد بررسی قرار گرفته است. شبیه‌سازی صحت‌سنجی شده، رویکردی کم‌هزینه و جایگزین انجام تجربی فرایند برای تعیین مقادیر بهینه است. پارامترهای فرایندی قابل‌تغییر بر روی دستگاه تزریق به‌عنوان پارامترهای ورودی در نظر گرفته شد. از روش غربالگری داده، پارامترهای مؤثر بر فرایند شناسایی شد. سپس از روش سطح پاسخ و تحلیل واریانس به ترتیب معادله رگرسیون دقیق‌تر برای پاسخ‌ها و مقادیر بهینه پارامترهای ورودی برای رفع عیوب مدنظر با کمترین مقدار نیروی گیره‌بندی موردنیاز به‌دست‌آمده است. درنهایت مشخص شد، مقادیر خروجی پیش‌بینی‌شده به روش طراحی مرکب مرکزی، میانگین خطای %6/03 با نتایج شبیه‌سازی دارند و درنتیجه، دقت پژوهش انجام شده را تأیید می‌نماید.
