The new QC3-33MM co-rotating twin-screw extruder is a new size not previously offered by the company.  It is designed for small-size lots of compounds and includes all of the company’s latest QC3TM (Quick-Change, Quick-Clean, and Quality Control) features.  These features were originally introduced on the ENTEK QC3-43MM co-rotating twin-screw extruder that the company launched at NPE 2015 in Orlando, FL.

The new QC3-33MM joins ENTEK’s other QC3TMmodels which include its 27MM, 43MM, and 53MM co-rotating twin-screw extruders.  ENTEK also manufactures 73MM, 103MM, and 133MM models.

Like the ENTEK QC3-27MM, 43MM and 53MM twin-screw extruders, the new QC3-33MM includes a wide range of Quick-Change, Quick-Clean, and Quality Control features. ENTEK worked closely with its customers to identify specific needs and used lean principles to deliver a machine that provides important benefits to compounders.

-Quick Change:  allows for fast, easy screw-set changeovers. New self-alignment feature takes the worry out of installing the screws into couplings. Guards come off quickly, and go back on the same way.   Tools for changeover and maintenance are mounted at point-of-use on the extruder.

-Quick Clean:  New extruder frame design deflects dust and keeps machine clean under the hood, and Stainless Steel and powder-coated surfaces look great today and 10 years from now.

-Quality Control:  All QC3™ twin-screw extruders are engineered and built at ENTEK’s headquarters in Lebanon, Oregon U.S.A. Top-quality components manufactured here in ENTEK’s shop give years of top-quality performance.  Because ENTEK is a processor and a machinery builder, it features vertically integrated operations and has engineering and manufacturing capabilities that are second to none in the twin-screw extrusion market.

Company Will Display its New QC3®33mm Twin-Screw Extruder and Also High-Output 73mm Twin-Screw Extruder; Interactive Display Featuring Screw Layout Program Will Also Be Featured

The company will be displaying two machines in its booth: its new QC333mm twin-screw extruder, which was introduced in 2017 and is being shown publicly for the first time; and its high-output 73mm twin-screw extruder.  In addition, ENTEK will feature two interactive work stations at its booth showing the company’s unique screw-layout software program.  Visitors to the booth will be encouraged to use the program to see how easy and fast it is to input their information and design a screw layout that will work for their compounding needs.

The ENTEK QC333mm co-rotating twin-screw extruder is a size not previously offered by the company.  It is designed for small-size lots of compounds and includes all of the company’s latest QC3® (Quick-Change, Quick-Clean, and Quality Control) features.

The new QC333mm joins ENTEK’s other QC3 models which include its 27mm, 43mm, and 53mm co-rotating twin-screw extruders.  ENTEK also manufactures 73mm, 103mm, and 133mm models.

ENTEK launched this new twin-screw extruder due to customer demands for this specific sized machine.  “Our 27mm twin-screw extruder is excellent for lab environments, and our 43mm is designed for small to medium-sized lots of compounds,” said Linda Campbell, Director of Sales at ENTEK Extruders.  “We were getting a lot of requests from customers for something in-between – a machine specifically designed for small lots, but with more output than the lab machine.”

Like the ENTEK QC327mm, 43mm and 53mm twin-screw extruders, the new QC333mm includes a wide range of Quick-Change, Quick-Clean, and Quality Control features. ENTEK worked closely with its customers to identify specific needs and used lean principles to deliver a machine that provides important benefits to compounders.

Also, featured at ENTEK’s booth at NPE2018 will be the company’s 73mm Twin-Screw Extruder for High-Output Custom Compounding.  This machine is one of ENTEK’s most popular models, used in the field for numerous compounding applications including production of bioresins, wood-plastic composites, large lots of color compounds and many others.  The 73mm machine is available with a 600 hp motor and screw speeds up to 900 rpm.

Co-rotating twin-screw extruders are extensively used for the preparation, compounding, mixing, and processing of plastics, but also in other industry branches, such as in rubber and food processing, and increasingly in the pharmaceutical industry too. Derived from the classic, bestselling work "Co-Rotating Twin Screw Extruders," this book brings much of the content up to date, with an expanded focus on the fundamentals of co-rotating twin-screw extrusion, including functional zones in the extruder, screw elements, material behavior, flow properties, performance behavior, and application of computational fluid dynamics.

Co-rotating twin-screw machines usually have modular configurations and are thus quite flexible for adapting to changing tasks and material properties. Well-founded knowledge of machines, processes, and material behavior is required in order to design and operate twin-screw extruders for economically successful operations. With chapters written by many expert authors from industry and academia, this book provides valuable information on applications from a practical perspective, suitable for both beginners and experienced professional engineers.

There are many types of plastic extruders in the market, such as single screw extruder, co-rotating twin screw extruder, counter-rotating twin screw extruder, planetary extruder, etc. Each type of extruder has its own unique mechanism design to respond to the production of various plastics. Among them, CYKF Co-rotating Twin Screw Extruder is the most popular product deeply trusted by customers worldwide. It is also the key consideration for high strength Composite Material Extrusion.

Composite material consists of two or more constituents, i.e. polymers, metal, or ceramic, which is multiphase material made by a variant forming process. It possesses advantages from all the material components, contributing to a new kind material with better property performance. The development of plastic composite is quite diverse and complex, and the variability in the material extrusion process is also different. Good extruder design can bring outstanding physical properties to the material while poor extruder design will lead to disappointing material properties that increase defect rate of production.

Many people may ask, single screw extruder can also produce plastic composite, why choose co-rotating twin screw extruder? The reason comes from the two screws of co-rotating twin screw extruder. Different from the all-in-one screw design as single screw extruder and counter-rotating twin screw extruder. Through highly flexible arrangement of the screw elements plus our high-precision screw processing capabilities, they can enhnce plastics, additives and fillers with sufficient and even dispersion, stirring, compression and mixing behaviors. This is what a single screw extruder can’t reach.

The design of the co-rotating twin screw extruder includes a heating system, a heat dissipation system, and a die in addition to a screw design. The design of all related systems must be balanced with each other to optimize the performance of the equipment. As the screw can be known as the heart of the extruder.

If the screw element with unmatch arrangement and combination, processing poor accuracy or used the material with inferior durability, the produced plastic pellets will have poor physical properties and instability, or even contain impurities materials. Eventually, the low-quality pellets will affect the results of injection or extrusion production. Therefore, a good screw design can brings a smooth, high quality and high efficient production to the extruder, which is one of the key factors of the production capacity.

CYKF"s CK-HT co-rotating twin screw extrusion line series are constantly evolving from the development of customer
