 Entek’s Top Twin-Screw Extruders for Compounding

Entek’s Top Twin-Screw Extruders for Compounding

Compounding—the backbone of several industries such as plastics, rubber, chemicals, recycling, food, and pharmaceuticals. Compounding is the art and science of mixing and melting different materials to forge new products with enhanced properties and performance. To realize this alchemical transformation, one requires reliable and innovative machinery. This is where Entek, a forerunner in providing engineered solutions for plastic, rubber, and silicone extrusion, takes center stage. This article will explore Entek’s twin-screw extruders and why they are the preferred option for compounding applications. We will highlight their unique features and benefits. Additionally, we will discuss the value they bring to the compounding process.

Embarking on a Revolutionary Journey: Entek’s Story

Larry Keith, an avant-garde in the domain of extrusion, laid the foundation for Entek in 1984. Initially recognized as a go-to provider for replacement parts—be it screws, barrels, or liners—for extruders from other manufacturers, Entek’s ambitions soared much higher. By 1991, the hum of gear manufacturing bore witness to Entek’s unveiling of their twin-screw extruders. These weren’t mere machinery but symbolized sheer performance, unparalleled quality, and robust durability.

The company’s growth trajectory saw another monumental leap in 2004 with the acquisition of the extrusion division of John Zink Company, a global torchbearer in combustion technology. This amalgamation did more than just expand Entek’s portfolio; it embedded the company within the influential Koch Industries family, one of the world’s largest privately held corporations.

Extruding Excellence: Why Entek’s Twin-Screw Extruders Stand Out

Entek’s twin-screw extruders are a marvel in the realm of compounding, boasting:

  • High Torque: A torque density soared up to 18 Nm/cm3, making them adept at processing various materials at stellar output rates.
  • High Speed: With a maximum screw speed reaching 1200 rpm, these machines promise impressive shear rates and immaculate mixing quality.
  • High Free Volume: A D o /D i ratio touching 1.61 offers these extruders the coveted high free volume, enabling them to master high filler loadings and manage low bulk density materials with ease.
  • High Flexibility: Their modular design facilitates configurations with diverse screw elements, barrel sections, and downstream equipment, making them the Swiss Army knife of compounding applications.

Compounding Mastery Across Materials

Entek stands at the vanguard of compounding technology, catering to a wide range of materials with unparalleled efficiency. For those delving into plastic compounding, Entek’s machinery seamlessly processes an array of types, including PO (polyolefin), PVC (polyvinyl chloride), and the high-performance PEEK (polyether ether ketone). If your endeavors veer towards rubber, rest assured that Entek can proficiently handle varieties such as EPDM (ethylene propylene diene monomer) and NBR (nitrile butadiene rubber).

Beyond plastics and rubber, Entek’s extruders demonstrate exceptional versatility. They adeptly manage chemical compounds, from stabilizers to catalysts. In the recycling sector, these machines champion the processing of materials like polyethylene, ensuring sustainability. For the food industry, Entek’s solutions effortlessly compound essential ingredients, encompassing everything from basic starches to complex proteins.
