This article discusses the key factors affecting glass fiber reinforced plastic compounding in a twin screw extruder. It highlights the importance of proper screw configuration, L/D ratio, and the use of a side feeder to ensure efficient dispersion of glass fibers and stable processing. Optimizing these parameters can improve product quality, enhance mechanical properties, and increase the overall efficiency of the plastic pelletizing process.

The article outlines the key considerations in plastic pellet production, focusing on four critical aspects: raw material preparation, extrusion process control, equipment operation, and quality management. Proper material sorting and drying help prevent contamination and defects, while precise control of temperature, screw speed, and feeding rate ensures stable plasticization and uniform pellet quality. Regular equipment inspection, correct cooling methods, and proper cutter adjustments are essential for efficient and safe production. Additionally, strict quality testing and workplace safety measures help maintain consistent pellet performance and reliable manufacturing operations.

This article explains the essential equipment required for TPE pellet production and how machine selection depends on production scale, formulation complexity, and product quality requirements. It highlights the roles of extruders, pelletizing systems, mixing equipment, and auxiliary devices, while outlining suitable configurations for small, medium, and large-scale manufacturing.

This article explains the importance of in-house plastic recycling (Post-Industrial Recycling, PIR) for manufacturers. By converting production scrap such as films, bags, and injection molding waste into reusable pellets, companies can reduce material costs, improve quality control, and support circular economy goals. In-house recycling also minimizes outsourcing expenses, lowers carbon footprint, and creates additional economic value by transforming plastic waste into marketable raw materials.

The article explains why PA (nylon) is sometimes added during TPE pelletizing and highlights its role as a performance-enhancing modification material. By blending PA with SEBS or SEPS-based TPE through twin-screw extrusion compounding, manufacturers can significantly improve mechanical strength, heat resistance, chemical resistance, and dimensional stability. The article also discusses material selection, compatibilizer design, processing optimization, and typical high-end applications such as medical devices, wearable products, and automotive components.

This article explains how to properly adjust the temperature of a plastic pelletizing machine and provides solutions to common pelletizing defects such as pellet sticking and hollow pellets. It highlights the importance of setting temperature profiles based on material properties, monitoring processing parameters, and maintaining proper cooling and venting systems. By optimizing these factors, manufacturers can improve pellet quality, enhance production stability, and reduce material waste during plastic extrusion and pelletizing processes.

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.

Nanjing Haisi Extrusion Equipment Co., Ltd. will be on holiday from February 14, 2026 (Saturday) to February 23, 2026 (Monday) in celebration of the Chinese New Year (Spring Festival).

Laboratory pelletizing extruders are compact, high-precision machines designed for polymer research, formulation development, pilot production, and small-batch pellet manufacturing. They operate using the same principles as industrial extrusion systems but provide greater flexibility, lower material consumption, and precise process control. These machines support applications such as polymer compounding, masterbatch production, biodegradable material development, and reactive extrusion. By enabling accurate testing of screw configurations, temperature profiles, and processing parameters, laboratory pelletizing extruders serve as a critical bridge between material development and full-scale industrial pellet production.

Color masterbatch is a highly efficient solution for coloring plastics, produced through precise pigment dispersion and compounding technology. Using a twin screw extruder, pigments and carrier resins are uniformly mixed, melted, and pelletized to ensure excellent color consistency, dispersion, and process stability. This technology is widely used in packaging, automotive, and consumer plastics, providing reliable and high-quality coloring performance in modern plastic manufacturing.
