- Causes And Prevention Measures for Material Overflow at The Exhaust Port in Plastic PelletizingMaterial 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.Products Release March 10, 2025

- 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.Products Release March 06, 2025
- Indispensable Precision Metering Component – Melt PumpThis 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.Products Release March 03, 2025
