This article provides a practical guide to solving common problems in plastic pelletizing, including long pellets, fused pellets, black spots, and discoloration. It explains the root causes of each issue—such as unstable strand feeding, insufficient cooling, equipment contamination, improper temperature control, and poor mixing. The article also offers effective solutions, including optimizing cooling systems, maintaining cutter blades, improving material handling, thoroughly cleaning equipment, and adjusting extrusion temperatures and screw configurations. By controlling every step from raw material to finished pellets, manufacturers can enhance pellet quality, reduce waste, and improve production efficiency.

The color masterbatch polishing machine is a specialized device designed to refine the surface of color masterbatch granules used in plastic manufacturing. It operates through high-speed friction and grinding to remove surface irregularities, producing smooth and glossy pellets. This process enhances the dispersion and visual quality of masterbatches in plastic products. By improving surface finish, increasing production efficiency, and reducing labor costs, the polishing machine plays a vital role in enhancing product appearance, performance, and overall competitiveness in the plastic extrusion and processing industry.

This article discusses how to increase the output of a twin-screw extruder by optimizing the screw configuration. It explains how improvements in feeding efficiency, melting performance, side feeding design, mixing quality, and pressure build-up can enhance extrusion productivity. By adjusting the screw elements, such as conveying and kneading blocks, manufacturers can achieve higher throughput, better material dispersion, and more stable processing without changing the extruder size.

This article introduces four main methods of physical blending for polymer modification: dry powder blending, melt blending, solution blending, and emulsion blending. Among them, melt blending using extrusion equipment, such as single-screw and twin-screw extruders, is the most widely applied in industry due to its efficiency and ability to achieve fine dispersion. Each method has its own advantages, limitations, and application scenarios in research, testing, and industrial production.

Seaweed–polymer extrusion is an innovative and sustainable method of processing seaweed directly into polymer materials such as pellets, films, filaments, and 3D-molded parts. Unlike conventional fossil-based polymer production, this process minimizes CO₂ emissions while utilizing all natural seaweed components. The resulting seaweed-based polymers, known as Carraphane, offer biodegradable and eco-friendly packaging solutions with potential applications in films, small parts, and recyclable products. Continuous research aims to enhance water resistance and expand their role in the circular economy.

Q1.The length is larger than the normal pelletA: Cause of occurrence:The main reasons are: starting the machine, pulling or breaking the strip, the direction of the strip is not straight, the strip is not properly soaked in water, and the cutting tool of the granulator is worn or has gaps.Main solut

We are familiar with TPE materials as formula materials, which are composed of SEBS, plastics, filling oil, fillers, and other additives. Based on SEBS and other related materials, they all have good processing performance and an important processing process called "granulation". The granulation pro

With the progress of society, the car floor mat industry has become increasingly mature, and the raw materials used have also been concentrated from the original XPE, EVA and other materials to PVC, and TPE materials that have sprung up in recent years.TPV and TPE are the current mainstream material
