Plastic sealing strips are commonly seen in buildings in southern regions and can be considered a familiar everyday product. Today, we’ll introduce the manufacturing process and production flow of plastic sealing strips. As we all know, these strips are produced by extrusion using a plastic extruder. But how does the extruder carry out this process? First, the extruder works with plastic pellets: the raw plastic material is thoroughly mixed with auxiliary additives in a kneader, and then granulated by a pelletizing machine.

Plastic weatherstripping is commonly seen in buildings in southern regions and can be considered a ubiquitous product in everyday life. Today, we’ll introduce the manufacturing process and production flow of plastic weatherstripping.
We all know that plastic sealing strips are manufactured by extrusion using a plastic extruder. So how exactly does a plastic extruder carry out this extrusion process? To understand this, we need to recognize that during extrusion, plastic pellets are fed into the machine, and the raw plastic material is first mixed with auxiliary additives in a kneader.
The materials are thoroughly mixed and then granulated by a pelletizing machine. The quality of plastic products is entirely determined by the quality of the plastic pellets, making the pelletization process critical. Raw materials enter the feed hopper of the plastic pelletizer, where they are heated to a specified temperature.
The barrel and screw are reprocessed to ensure the product achieves the desired profile at the pelletizing die, after which a haul‑off unit draws it through to the pelletizer for cutting, completing the pelletizing process. Once the plastic pellets are produced, they can be directly fed into an extruder for further processing.
Once the product has been finalized and cooled in the cooling tank, it is ready for installation.
