The extruder is equipped with 2 individual heating units. Heating or cooling of extrusion barrel and head is controlled respectively by 2 water tanks via thermoregulators with digital display. The set temperature and the actual temperature are shown on the display. Automatic adjustment starts when temperature has been set.
A sliding clutch connects the infeed rollers with the gearbox. Release of the clutch disconnects the infeed rollers from the gearbox, enabling the top extrusion chamber and the infeed rollers to be opened through a hinge for cleaning.
The gearboxes are also installed on the extruder. Each unit includes gears gone through thermal process. All axles are fixed on ball bearings. The gears and the bearings run in an oil bath. The hydraulic reservoir is filled with special oil resistant to high-pressure. The level of the oil can be observed by level glass. An electronic over-pressure protection device is fitted in each barrel accurately controlled by a microprocessor.
One A.C. frequency converter together with main driving motor is introduced to infinitely adjust the extrusion speed.
Each set of extrusion screws is assigned with a variator to regulate the ratio depending on various raw materials to be extruded. “Speed Up” or “Slow Down” Operation is achieved by a variator when the ratio has been fixed.
The extruder is equipped with 2 thermo-regulator with temperature display. All electric components and adjustment device are positioned at eye's level. All contactors, relays and fuses are installed in the control cabinet.
