This article provides an overview of thermoplastic elastomer (TPE) recycling methods, including mechanical recycling, material reuse, chemical depolymerization, and energy recovery. It explains how TPEs and TPVs can be reprocessed through grinding, melt filtration, and pelletizing, highlights closed-loop recycling in automotive applications, and introduces advanced separation technologies such as magnetic sorting for complex overmolded and co-extruded materials.

This article analyzes the common causes of strand breakage in plastic pelletizing. It identifies external and internal impurities, poor plasticization, raw material inconsistencies, venting issues, and improper cooling or traction mismatch as key factors. Practical solutions are suggested, such as optimizing temperature, filtration, raw material compatibility, and venting efficiency to prevent strand breakage and ensure smooth pellet production.

This article provides a comprehensive guide to the rotating blades used in pelletizers, covering their material types, tooth profile classifications, lifespan analysis, and proper maintenance methods. It explains the differences between blades used for underwater strand pelletizing and dry cutting, details key parameters of blade teeth, identifies common sharpening mistakes, and offers best practices for extending blade life and maintaining cutting efficiency. Proper full-profile grinding and maintaining original blade angles are emphasized to ensure optimal pellet production and blade durability.

The article discusses essential equipment for TPE pellet production, including extruders, pelletizers, and auxiliary systems. Equipment choice depends on production scale, with larger setups requiring more advanced automation. Contract manufacturing is an alternative for companies with limited capacity.

The template of the extruder consists of a template body with a discharge hole and a heat insulation layer, and is fixed to the die head with a threaded rod. Only when the discharge speed of each die hole is consistent can particles of uniform size be cut out. During use, there are many factors that affect the smooth flow of the template. When the template is severely blocked, it will affect the appearance of the particles, the service life of the cutter, and cause shutdown.

As an environmentally friendly mechanical production equipment, plastic pelletizers produce useful granular plastics, but for these plastic production machinery and equipment, necessary maintenance is still required, especially in daily life. Some maintenance before and after production can maintain the normal operation of the equipment and extend its service life, which is also very good for users.

The plastic extruder pull bar granulation production line can be used for granulation of masterbatch, PE/PP+CaC03 materials, or recycling granulation of LDPE, HDPE, PP, ABS, PET and other raw materials.
