• What Is A Triple-Screw Extruder? How Adding One More Screw Transforms Plastic Compounding

  The article explains what a triple-screw extruder is and how adding a third screw significantly improves plastic mixing and compounding. Compared to twin-screw extruders, triple-screw extruders offer multiple intermeshing points, resulting in better plasticizing, higher throughput, superior dispersive and distributive mixing, and improved energy efficiency. They excel in producing highly filled masterbatches with greater toughness and uniformity. The design also provides better degassing and even allows in-situ molecular grafting for specialty applications like PP foam beads. While twin-screw extruders remain ideal for precision reactive extrusion and small-batch production, triple-screw extruders are recommended for large-scale, high-capacity manufacturing, especially for materials requiring complex mixing and high filler content. The article concludes that triple-screw technology has strong potential in advanced compounding and future polymer processing.

• Tips for Adjusting Melt Flow of TPE During Pelletizing And Product Manufacturing

  This article shares practical methods to improve and control the melt flow rate (MFR) of TPE (thermoplastic elastomers) during pelletizing and injection molding. Key strategies include adjusting the oil content in SEBS/SBS base resins, optimizing formulations by selecting higher MFI PP/PS and adjusting fillers and lubricants, and fine-tuning processing conditions such as temperature, screw shear rate, injection speed, and holding time. Together, these approaches help achieve better flowability, stable processing, and high-quality TPE products.

• Preventing Injection Molding Defects in TPE And TPR Products: Start with Pelletizing

  To prevent common injection molding defects in TPE and TPR products—such as flow marks, sink marks, and gate breakage—manufacturers can improve melt strength by adding 5–15% TPV during pelletizing. TPV modification enhances molecular chain entanglement, improves dimensional stability, and slightly increases hardness while maintaining thermoplastic processability. For best results, TPV should be uniformly blended using a twin-screw extruder, with process adjustments made to account for higher melt viscosity. This approach helps achieve better product quality and reduces defects in thin-walled, complex molded parts like medical grips and precision seals.

• What To Do When Resin Degradation Pollutes Material in A Single Screw Extruder? Analyze And Adjust Screw Elements To Solve It!

  This article explains how to identify and resolve resin degradation in single screw extruders. Resin degradation, often caused by stagnant flow and high temperatures, leads to product contamination. The solution involves step-by-step screw removal, inspection, and design analysis—especially addressing issues like small thread radii, improper groove dimensions, and poorly designed mixing elements that cause Moffatt eddies and stagnation. Preventive measures include proper screw design, temperature control during shutdowns, and avoiding deep or narrow grooves that trap resin.

• Understanding The Side Vacuum Exhaust System: What You Need To Know

  This article explains the advantages of side vacuum exhaust systems in plastic extrusion. Unlike traditional top-mounted systems, side vacuum systems prevent material overflow by positioning the vacuum port laterally, improving process stability and reducing maintenance. It also clarifies that a stable negative pressure—not higher vacuum strength—is key to effective degassing. Factors such as temperature control, screw speed, and screw design also significantly impact performance. The side vacuum system is especially suitable for high-volatility materials where reliability is critical.
