Internal pores of POM injection molded products
ظاهرة المشكلة
Internal voids found in POM products.
تحليل الأسباب
POM is not sensitive to hydrolysis, but if it contains trace moisture or degradation gas, pores will form in the product; insufficient holding pressure is also a cause.
الحل
Drying treatment 80-90°C/2-4h; increase holding pressure; optimize venting.
الخلاصة الأساسية
POM pores are mainly related to gas generation and holding pressure.
