Polyolefin plastomer polyolefin plastomer process connection problem when switching production between different processing methods (Variant: Enhanced Measures)
Fenómeno do problema
When switching production from one processing method to another (such as '2079851475616104452 to extrusion), the product quality fluctuates greatly and requires a long time for debugging.
Poor process connection affects production efficiency and product quality.
In particular, additional attention is needed on the original basis; this problem is more prominent and requires focused attention.
Análise das causas
（1）Different processing methods have different material requirements (MFR, molecular weight, etc.)
（2）The parameter settings do not match after equipment conversion
（3）Operators are not familiar with the other processing method
（4）Raw material batch differences are superimposed on production change adjustments
（5）Insufficient preparation before production change
（6）On the original basis, additional attention is needed: fluctuations in process parameters or changes in equipment status have aggravated this problem
Solução
（1）Establish production change operating procedures and clarify the process parameter range for each processing method
（2）Prepare suitable material grades before production change
（3）Operators are trained in multiple processing methods
（4）Do small-batch trial production first when changing production, and start batch production after passing the test
（5）Establish material processing adaptability files
（6）And strengthen process monitoring; on the original basis, additional attention is needed to pay special attention to parameter stability
Conclusão principal
Production change connection requires advance planning and sufficient preparation, and the key is to clarify the differentiated requirements of different processing methods for materials.
Targeted preventive measures need to be taken in different production scenarios.
