This article introduces a compact strand cutter designed for small-scale and pilot filament recycling. The machine converts extrusion strand waste into uniform pellets, improving material reuse and reducing production costs. With multi-strand support, adjustable cutting speed, easy maintenance, and a space-saving design, it provides an efficient recycling solution for R&D lines and small filament production using materials such as PLA, ABS, PETG, and TPU.

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".

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.
