Working principle of sealing strip extruder

1.Raw material preparation: First, according to the requirements of the production of seals, raw materials such as tree fat powder, oil, calcium powder, etc. are mixed evenly in proportion to make plastic particles. Heat plasticization: In the extruder, plastic particles are heated and plasticized, subjected to intense shearing and mixing between the screw and the barrel. 

2.Extrusion molding: Through the rotation of the screw, the plastic particles are fed into the mold area and squeezed through the die head flow channel under a certain pressure to form the required seal shape. 

Cooling treatment: The extruded seal usually needs to be cooled to improve its physical properties and heat resistance.

Follow-up processing: According to customer needs, it may also be necessary to shear, bonding and other follow-up processing, and packaging and shipping as required. 

3.The above steps summarize the main working principle of the sealing strip extruder to ensure the quality and production efficiency of the sealing strip.
