PA6 Winter Workshop Compensation
ظاهرة المشكلة
PA6 products produced in winter with the same set of process parameters are undersized and brittle
تحليل الأسباب
In winter the workshop temperature is low, mold heat dissipation accelerates making the actual mold temperature lower than the set value, the melt front cools quickly, the filling pressure loss is large, and the product density and dimensions change
الحل
In winter, appropriately raise the mold temperature setting by 5-10°C and confirm by actually measuring the cavity surface temperature; take the upper limit for barrel temperature, insulate the workshop or add insulation boards to the mold to reduce heat dissipation
الخلاصة الأساسية
Seasonal temperature changes alter the actual process conditions, and winter compensation is based on the actual measured mold temperature; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
