What is the significance of the melting length of plastic in an extruder? This issue arises during the plastic processing process. Depending on the melting length, the processing properties of the plastic also change. Please discuss and explain this based on actual situations; those who provide detailed answers will receive a high reward!
The total length in the extruder, from the start of melting until the width of the solid bed drops to zero, is called the melting length. The value of the melting length reflects the melting rate of the solid; generally, the higher the melting rate, the shorter the melting length.
