Description of Parts TEK-MHS Series – Premium models of the highest throughput and speed Autoguard Screw & Shaft The screw of the extrusion machine is where the feeding, melting, mixing and dispersion of the raw materials as well as degassing and pressure-generation occur. A proper type of screw and its materials can be selected, depending on the raw material and additives to run. The screw, which consists of various elements, is powered through the spline axis at a high output. Screw elements are assembled individually in the shaft to which high power is transmitted by an involute spline. This...

Twin Screw Extruder Strand Cutting System The most commonly used system. The polymer compounded in the extruder passes through the Breaker Plate of the die head at the end of the barrel. The polymer is discharged through a die nozzle into multiple strands by extrusion. The polymer through the nozzle is cooled in a water-bath, dried with air wiper, and cut into about 3~6mm length in the pelletizing machine. The cut pellets are classified into quality products, dust and long-cuts according to their size using a vibrating screen. The quality products are transferred to storage or packing process....

Under Water Cutting System(UWC) The polymer compounded with the extruder is discharged from the nozzle on a circular die at the end of the barrel. The polymer is cut into pellets by rotating knives and cooled in water, and transferred to the centrifugal dryer. The pellets transferred to the centrifugal dryer are separated into water and pellets. The pellets are transferred to the vibrating screen by a turbo rotor blade. The cooling water is cooled down and circulated with heat exchanger and pump. The cut pallets are classified into quality products, dust and long-cuts according to their size...

Water-Ring Cutting System The polymer compounded in the extruder is discharged through a circular die nozzle at the head of the barrel, cut into pellets, mixed up with water which is rotating outside of the die, and be cooled down and transferred in a slurry form. ■Flow Diagram The pellet is transferred to a centrifugal dryer and separated into water and pellets by a perforated plate. The pellets are transferred to the vibrating screen by a rotating blade. The cooling water is cooled down and circulated with heat exchanger and pump. The cut pallets are classified into quality products, dust and...

Screw & Shaft Depth Screw and Spline Shaft Di (In Diameter) The screw’s intermeshing ratio is 1.55 (the outside diameter of the screw divided by the root diameter). The features of the screw are as shown in the side diagram; the functions of the screw including feeding, melting, mixing and dispersion of the raw materials aas well as degassing and pressure-generation are shown in the below diagram. dp - Type Screw(Do / Di =1,62) CL (Center Distance) A wide range of screw types and special materials that can meet diverse customer requirements. High-power transmitting involute spline. The screw’s...

Control System The extruders are equipped with HMI SYSTEM automatic control system to control the operation according to the inputs/outputs set up that entered by the user. The control system which based on PID controls the temperatures of the extruder components, screw speed, raw material feed rate, and raw materials feed ratio at optimal conditions. Main Control Screen Data of the extrusion lines are displayed on the screen. Click the menu in the menu bar at the top screen to go to desired page or create a report. ■Computerized Control System Process Chart Touch Screen(Proface) GP-4000 Series...
