TEM Series Co-Rotating, Twin-Screw, Compounding Extruders.
The NFM/Welding Engineers' TEM Series* co-rotating, intermeshing twin-screw line offers the highest torque-per-free-volume and the highest screw speed of any of the major twin screw competitors. Manufactured in North America, it is avaialble in 41mm, 48mm, 58mm, 75mm, 93mm, 104mm and 136mm models. The TEM Series has evolved into one of the most innovative, productive compounders, ensuring uniform dispersion. The increased torque of the patented redesigned gearbox with high screw-free-volume assures high quality production at a low resin temperature. Production cost are lower as a result of TEM Series compounders' easy operation and simplified maintenance.

FEATURES
  • Higher Torque: The TEM Series provides 15% higher torque-per-free-volume than its major competitor. The higher torque enables the extruder to produce more horsepower, which in turn creates higher throughput rates. Higher torque also assures higher filling of the screw flights lowering the overall average shear rate and in turn, the final melt temperature.
  • High Screw Speed: The higher torque-per-free-volume allows for a lower melt temperature and the capability to run at higher speeds. The higher screw speed increases power input and production rates nearly linearly. The shorter time reduces the heat history on the product.
  • Compact Design: The closed-looped Barrel Cooling System is mounted on the same base as the compounding extruder, creating a compact design. The redesigned patented gearbox is more powerful and compact in its configuration creating a smaller machine footprint.
  • Enhanced Performance: By increasing the torque and speed, the machine efficiencies are increased, allowing more material to be processed at a higher product quality. These efficiencies also save energy by lowering specific engery (kwh/hg).
  • Upgraded Package Control: Standard PLC control packages include a Graphic Machine to Man interface with a (PC) interface ethernet link. This system enables precise monitoring and variable adjustment by the operator.
  • Ease of Maintenance: The TEM Series provides the structural and functional design for total ease of operation. From the patented high torque gearbox, through features such as unique vent ports and Quick Clamp Die head design, the TEM Series provides for less contamination and maintenance while maintaining smooth flow of material.
OPTIONAL EQUIPMENT
  • QUICK CLAMP DIE: Designed to significantly reduce machine downtime, the NFM/Welding Engineers' Quick Clamp Die eliminates the timely changing of the breaker plate and screen. The Quick Clamp Die incorporates a manual or hydraulic cylinder to quickly and easily access the die area instead of the conventional models that use numerous bolts. The Quick Clamp Die is custom-dsigned for each specific processing equipment.
  • SIDE FEED DESIGN: NFM/Welding Engineers has a standard line of side-feeders for every TEM Series model as well. Using a new design, these high-speed, high free-volume feeders enable you to maximize processing throughput. Complete with casters, these feeders can easily be moved and stored when not in use.
KEY DESIGN ELEMENTS
  • BARRELS: (Wear Protected) Standard TEM Series' barrels are made using a carbide lining (or alternate 10V liners) for wear resistance. The barrel design, when combined the use of screws made from wear-resistant steel alloys, produces an overall endurance of the machine which is vastly improved compared to conventional-type machines.
    Barrel configurations include:
    • Feed Barrels
    • Vent Barrel
    • Closed Barrels
    • Side-feed Barrel
  • SCREWS: Backed by years of hands-on experience, NFM/Welding Engineers produces a wide range of self-wiping, twin-screw designs for every processing application. Built with involute spline shafts, our screws offer strength for super-high torque transmission. Wear-protected with crucible 9V material (with an option of a 10V soft core), these screws are wear resistant and capable of handling the most demanding processing environments.
