Process Connection Problem When Switching Between Different Processing Methods of Polypropylene
Fenómeno del problema
When switching from one processing method to another (such as '2079851475616104452 to extrusion), the product quality fluctuates greatly and requires a long time for adjustment.
Poor process connection affects production efficiency and product quality.
Análisis de la causa
(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 the transition adjustment
(5) Preparation before the transition is insufficient
Solución
(1) Establish transition operating procedures, specifying the process parameter range of each processing method
(2) Prepare suitable material grades before the transition
(3) Operators are trained in multiple processing methods
(4) Conduct a small-batch trial production first during the transition, and start mass production after passing the inspection
(5) Establish a material processing adaptability file
Conclusión clave
Transition connection requires advance planning and full preparation; the key is to clarify the differentiated requirements of different processing methods for materials.
