What factors are related to the extrusion quality of FEP hose<\/h1>\n

What factors are related to the extrusion quality of FEP hose?<\/p>\n

The extrusion quality of FEP hose has a certain relationship with the following related parameters. A certain factor may cause the quality of FEP pipe extrusion to be different from the ideal.<\/p>\n

1. Temperature<\/p>\n

Extrusion molding temperature includes barrel temperature, plastic temperature, screw temperature, generally we measure barrel temperature. The temperature is controlled by the heating and cooling system. Due to the screw structure, the instability of the heating and cooling system, and the change of the screw speed, the temperature of the extruded material fluctuates in the radial and axial directions, which affects the quality of the product. The strength of the product is different. Residual stress, the surface is dull and dull. To ensure product quality, the temperature should be stable.<\/p>\n

2. Pressure<\/p>\n

\u00a0 \u00a0 Due to the structure of the screw and barrel, the resistance of the machine head, filter screen, and filter plate causes pressure inside the plastic. The pressure change is shown in the figure, and the pressure also fluctuates.<\/p>\n

3. Extrusion rate<\/p>\n

\u00a0 \u00a0 The mass or length of the plastic extruded from the die of the extruder per unit time. Factors affecting the extrusion rate: head resistance, screw and barrel structure, screw speed, heating and cooling systems, and plastic characteristics. But when the product has been determined, the extrusion rate is only related to the screw speed. The extrusion rate also fluctuates, which affects the product geometry and size.<\/p>\n

There are fluctuations in temperature, pressure, and extrusion rate. In order to ensure the quality of products, the source manufacturer of Shenzhen Dankai Fluoroplastics reminds everyone: the screw should be designed correctly, the heating and cooling system and the stability of the screw speed should be controlled to reduce parameter fluctuations.<\/div>","protected":false},"excerpt":{"rendered":"
