• How To Choose The Right Laboratory Extruder

  Laboratory extruders are compact, high-precision extrusion machines designed for material research, small-batch production, and educational use. Compared to industrial extruders, they feature flexible modular design, precise control systems, and lower throughput, making them ideal for polymer modification, masterbatch development, reactive extrusion, and pilot-scale testing. With screw diameters typically ranging from 12 to 45 mm and output capacities of 0.25–150 kg/h, lab extruders provide critical data for process optimization, scale-up validation, and innovative material development across plastics, pharmaceuticals, and food industries.

• Why There Is No “Universal” Screw Design for All Polymers

  This article explains why a universal screw design for plastic extrusion does not exist. Different polymers, such as HDPE and HIPS, have unique thermal, viscoelastic, density, and friction properties that directly affect melting, conveying, and throughput. These variations make it impossible for one screw geometry to efficiently process all materials, highlighting the need for polymer-specific screw designs to ensure optimal extrusion performance.

• Why Single Screw Extruders Cannot Replicate The Mixing Performance of Twin Screw Extruders

  This article explains why a single screw extruder cannot replicate the mixing performance of a twin screw extruder. Twin screw extruders enable full-channel mixing, controlled shear distribution, and efficient additive dispersion, while single screw extruders face limitations in shear balance, melt flow, and throughput. The flexible design of twin screw systems allows repeated high-shear mixing with minimal heat buildup, achieving superior compounding and homogenization.

• 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.
