• Causes And Prevention Measures for Material Overflow at The Exhaust Port in Plastic Pelletizing

  Material overflow at the exhaust port during the TPE pelletizing process can impact production efficiency and product quality. The main causes include improper equipment configuration, inadequate temperature control, and poor filter management. To prevent overflow, manufacturers should ensure the feeding speed matches the main extruder speed, adjust the screw-barrel clearance, and install reverse conveying elements. Temperature should be precisely controlled to avoid incomplete plasticization or excessive material fluidity. Regularly replacing or cleaning filters and selecting appropriate filter apertures can also help prevent clogging and overflow. Implementing these measures ensures stable production and high-quality TPE pellets.

• How To Optimize The Single-Screw Extruder for Melt Feeding When A Twin-Screw Extruder Is Followed by A Single-Screw Extruder?

  This article discusses how to optimize a single-screw extruder for melt feeding when it follows a twin-screw extruder in a compounding production line. It focuses on the importance of the metering channel depth in the single-screw extruder, as this affects the specific throughput rate and discharge temperature. A deeper metering channel reduces the specific throughput rate and increases the discharge temperature, which can degrade sensitive additives like flame retardants. The article presents a case study of a 15-inch diameter screw with an initial metering channel depth of 1.73 inches, which leads to inefficiencies. It then proposes an optimized screw design with a shallower channel depth of 1.18 inches, improving throughput and reducing discharge temperature. The optimized screw requires additional torque, and its design factors include screw lead length and metering channel depth as a percentage of screw diameter.

• Indispensable Precision Metering Component – Melt Pump

  This article introduces the melt pump, a crucial component used for transporting high-temperature molten materials in various industries like plastics, rubber, chemicals, and food processing. It explains the working principle of the melt pump, which is based on a gear pump mechanism, and describes its three stages: intake, transfer, and discharge. The article also covers different types of melt pumps, including straight tooth, helical tooth, and screw tooth pumps, highlighting their unique features and applications. Additionally, it discusses the key functions of melt pumps, such as pressure stabilization, precise metering, and improved mixing efficiency, as well as their key performance indicators, including flow rate, temperature, and pressure.

• Causes of Excessive Smoke During Elastomer Pelletizing And Preventive Measures in Formulation And Process

  This article discusses the causes of excessive smoke during elastomer pelletizing and the preventive measures to address the issue. Key causes of smoke include raw material quality problems (such as impurities and moisture), improper temperature control in the extruder, excessive extrusion speed, and formulation issues (e.g., low-viscosity or low-flashpoint oils). The article suggests several preventive measures, including optimizing the formulation by selecting high-temperature-resistant materials, improving pelletizing processes by controlling temperature and extrusion speed, maintaining equipment regularly, and using high-quality base materials and oils. These measures help reduce smoke formation, improve safety, and enhance pellet quality during the elastomer pelletizing process.

• Twin-screw Granulator Main Engine Operation Precautions And Shutdown Operation Methods

  When operating a twin-screw pelletizer, special attention must be given to the main machine to ensure stable performance. Key precautions include maintaining proper current levels, monitoring pressure sensors, and checking lubrication oil pressure. Shutdown operations fall into two categories: normal shutdown and emergency shutdown. Normal shutdown involves gradually stopping feeding, reducing screw speed, and turning off auxiliary equipment. In case of an emergency, the operator should press the emergency stop button and cut off power immediately before troubleshooting the issue.

• How To Clean The Extruder Screw!

  This article describes three extruder cleaning methods: 1.Resin Cleaning: Uses polyester or epoxy resin to clean new or used equipment, removing residual materials to prevent extrusion issues like reduced speed or color differences. 2.Disassembly and Cleaning: Involves adding washing material, stopping feeding, and disassembling the extruder to remove residual material and clean the screw and die head. 3.Fire Baking: A blowtorch is used to burn off plastic from the screw, leveraging the screw's heat to clean effectively.

• What To Do If The Die Hole of Underwater Pelletizing Is Clogged? Do These Three Things To Reduce The Frequency of Machine Cleaning

  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.
