Commonly used thermoplastic elastomer materials include TPE and TPU. Thermoplastic elastomers are a type of modified plastic that significantly outperforms conventional plastics in terms of performance. During production, thermoplastic elastomer products follow a manufacturing process similar to that of ordinary plastics: the raw material formulation is first converted into plastic pellets, which are then extruded. The basic structural design of a thermoplastic elastomer extruder is largely the same as that of a standard plastic extruder; however, because thermoplastic elastomers are more difficult to plasticize than conventional plastics, specialized modifications are required when designing the extruder for this application.

Commonly used thermoplastic elastomers include TPE and TPU. These materials are a type of modified plastic that significantly outperforms conventional plastics in terms of performance. In production, thermoplastic elastomer products follow a manufacturing process similar to that of ordinary plastics: the raw material formulation is first converted into plastic pellets, which are then extruded to produce the final product.
The basic structural design of a thermoplastic elastomer extruder is broadly similar to that of a conventional plastic extruder; however, because thermoplastic elastomers are more difficult to plasticize than ordinary plastics, specialized modifications are required during production. Typically, thermoplastic elastomers exhibit relatively poor plasticizing performance. Therefore, in the design of the extruder screw, a higher length-to-diameter ratio is employed, and the screw is made longer to ensure sufficient plasticization time for the final product.
Therefore, we can see that the plastic extruders used in thermoplastic elastomer production are specialized and cannot be shared with other types of plastic extruders. During manufacturing, we formulate the raw-material blend based on the desired product quality; once the materials have been thoroughly mixed in a kneader, they can be fed into a pelletizing machine for granulation. Thermoplastic elastomer sealing strips, TPE tubing, and other products are all produced via extrusion using these plastic pellets.
After plastic pellets are produced via extrusion, they undergo a series of processing steps—plasticization, shearing, and compounding—in the extruder. The extruder then shapes the material into the desired product form.
