FEP manufacturing process<\/h1>\n

FEP manufacturing process<\/p>\n

FEP has better processing performance. The following is what needs to be prepared before extrusion of FEP pipe:<\/p>\n

1) Feeding: Before FEP extrusion, pre-bake at 120\u2103 for about 3h.<\/p>\n

2) Conductive core preheating: In order to ensure the uniform temperature inside and outside the extruded FEP insulation layer, the conductive core should be preheated to 300-350\u2103.<\/p>\n

3) Temperature distribution of the extruder: Generally, the temperature distribution of the extruder from 280\u00b0C (feeding port) to 380\u00b0C (head) rises linearly;<\/p>\n

4) The stretch ratio of the die sleeve: should be selected in the range of 50-200.<\/p>\n

5) Screw speed: After adjusting the screw speed in cooperation with the temperature, do not change frequently during the FEP resin extrusion process, and adjust it slightly if necessary.<\/p>\n

6) Mold die mouth insulation: The insulation area should cover the entire stretching area, and the insulation temperature should be 350-380\u00b0C to avoid the formation of stress due to the sudden cooling of the surface of the FEP cone before it is formed, which will lead to insulation cracking.<\/p>\n

The product forms before FEP resin processing and molding are:<\/p>\n

1. Pellets, used for extrusion molding and injection molding;<\/p>\n

2. Dispersion liquid, used for dipping and coating;<\/p>\n

3. Powder material, used for electrostatic spraying.<\/p>\n

Below we mainly understand several molding processing methods of FEP.<\/p>\n

1. Melt extrusion molding<\/p>\n

2. Compression molding: heating, pressurizing and plasticizing; cooling, pressurizing to shape<\/p>\n

3. Blow molding<\/p>\n

4. Vacuum forming<\/p>\n

5. Injection molding<\/p>\n

6. Coating processing<\/p>\n

7. Electrostatic spraying<\/p>\n
