Extruders involves forcing a molten thermos plastic trough a die. Due to the complex process that is involved in extruders, your motor drives must ensure that you process the polymer at high and constant output rates. Therefore it is essential that you have a high degree of torque and speed stability. Also the pressure in the system must remain consistent, this means that you must maintain good control of process variables and speed.
When plastic sheets have been wound onto reels from the extruder, the next process would be to cut the sheets into size, or apply a lamination/printing.
This process requires, tension control, speed control also torque control. All of these are ideally suited to a DC Motor Control.
Haul off units are there to pull the extruded plastic at a uniform speed and no slippage. This process ensures the uniform dimensions. Due to the constant torque required in this process, and critical speed constants involved. DC Motor's and Thyristor Drives offer a cost effective and reliable solution.
You can choose from over 50 models of industrial motor controller. Here are three products that have an application in Plastics.
