Details about HFFR and Retrofitting cable extrusion

This HFFR cable extrusion comprises a knifer and twin screw plastic compounding extruder + single screw extruder for the production of cable. When using an HFFR cable compounding line, you can not only be certain that the raw plastic material melts properly, but you can also avoid material accumulation in the die head, which can lead to a decomposition reaction. The first compounding extruder is often operated at high speed to ensure proper mixing and a high output capacity. The second extruder must be a single screw extruder with a greater diameter and the ability to run at a lower screw speed. Because of the internal cooling system and the high heat exchangeability, the screw speed can be reduced to prevent overheating. The functional separation enables the operator to control the expected material mixing process and temperature than previously possible.

Submit

The raw components will be placed into the kneader and mixed together. It will be conveyed into the conical twin-screw force feeder via an automatic conveyor 8-15 minutes after receiving it. The HFFR cable compounding material will flow smoothly and automatically into the twin-screw extruder to make things even better. Afterward, it will flop into the single screw extruder to prevent it from building up in the die head. A substantial amount of die head pressure will be applied since the twin screws rotate at a high rate, such as 500 or 600 revolutions per minute (rpm). A decomposition reaction will occur if the components remain in contact with the die head for an extended period. It is preferable to utilize a twin-screw extruder in conjunction with a single screw extruder since it produces a higher capacity and a better result.

Application

Consolidate the advantages of twin-screw processing, such as high speed and extensive mixing, with the advantages of single screw processing, such as low speed, low temperature, and low shear. Intended for the compounding of heat- and shear-sensitive materials, such as HFFR for cable, PVC compounds for cable, shoe soles, clear containers, and medical applications. EVA shield cable compounds; carbon black master batches of polyethylene, polyvinyl chloride, and other materials

Cross-linked cable material that is flame retardant, low in smoke, and devoid of halogens is a novel form of environmental protection cable material that has evolved in recent years as people's awareness of the importance of environmental protection has increased. However, the typical wire and cable insulation material polyvinyl chloride includes halogen and should not be used for electrical wiring. Accidental combustion of wire and cable will generate toxic smoke, contaminate the environment severely, and make the firefighting and evacuation of firefighters more difficult and dangerous.

What is the rationale for retrofitting extrusion?

• Streamline the extruder control system's response time while simultaneously increasing the storage capacity of process data

• Construct a system capable of being integrated with other components of the Retrofitting of extursion lines while taking advantage of the advantages of Industry 4.0.

• Minimize the amount of money spent on maintenance and machine downtime that can occur when system components reach the end of their useful lives.

• Enhance the performance of existing measurement systems by incorporating electronic components and cutting-edge technology.
