Process transition problems when switching between different processing methods of low density polyethylene low density polyethylene
ظاهرة المشكلة
When switching production from one processing method to another (e.g., injection to extrusion), product quality fluctuates greatly and long debugging time is required.
Poor process transition affects production efficiency and product quality.
تحليل الأسباب
(1) Different processing methods have different material requirements (MFR, molecular weight, etc.)
(2) Parameter settings mismatched after equipment conversion
(3) Operators unfamiliar with the other processing method
(4) Raw material batch differences superimposed on transition adjustments
(5) Insufficient preparation before transition
الحل
(1) Establish transition operation procedures, clarify the process parameter range for each processing method
(2) Prepare suitable material grades before transition
(3) Operators trained in multiple processing methods
(4) Conduct small-batch trial production first during transition, mass production after passing inspection
(5) Establish material processing adaptability archives
الخلاصة الأساسية
Production transition needs advance planning and full preparation; the key is to clarify the differentiated material requirements of different processing methods.
