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.

Compared with strand pelletizing, underwater pelletizing has the advantages of better pellet quality, higher degree of automation and lower cost. However, compared with less sensitive commodity resins such as polyethylene, polypropylene or polystyrene, the risk of mold freezing is greater when producing engineering resins such as those mentioned in the previous paragraph.

But how to choose a suitable plastic pelletizing machine? In this article, we will walk you through the process of choosing a suitable plastic pelletizing machine, providing expert advice and practical tips.

Before processing and granulating, a complete set of granulation equipment is required, which is the TPE/TPR granulation production line. The basic components include mixing equipment, plasticizing equipment, cooling equipment, granulating equipment, and batch mixing equipment. Common TPE/TPR pelletizing production lines include "strand pelletizing", "underwater pelletizing" and "water ring pelletizing".

The twin screw extruder has a wide range of applications, and can process and produce a variety of products. We need to choose different auxiliary machines to adapt or improve the material characteristics, and make products perfect.

Based on the two processes of strand pelletizing and underwater pelletizing, we try to analyze seven common granulation problems and the corresponding solutions, and provide some suggestions for continuous mass production of quality products.
