FEATURES ● top quality by advanced technology. ● High speed and excellent extrusion quality by adopting two sets of single screw extruders with high efficiency performance. ● Unique design of composite die-head for large diameter winding pipe processing with high production efficiency. ● High quality of winding pipe produced by adopting the unique winding process for pipe forming. ● Easy operation and high performance by adopting an advanced PLC control system. Control System ● By adopting a PLC Control System with super high speed and large storage capacity, which is FP2 series of National Co., Ltd., Japan, the imported frequency converter and the DC speed regulators to realize the function of man-machine interaction with multi-window data collection and the function of switching between the linear and nonlinear speed. The PLC Control System is highly reliable and super accuracy of control. If the system RS232 port is connected with a Modem, it may have some special functions such as long-distance monitoring & data inputting, fault checking, trouble shooting and software upgrading functions. ● PLC Control System with super high speed and large storage capacity of Model: NAIS FP2, Japan. ● To realize the function of switching between the linear and nonlinear speed. ● The four control points i.e. forming pipe extrusion, melting pipe extrusion, winding and cutting process can be auto-tail controlled synchronously. ● Special functions: long-distance monitoring & data inputting, fault checking, trouble shooting and software upgrading functions can be provided if required. ● The forming pipe extruder with monitoring functions for temperature control, auto hopper filler, speed adjusting. ● Cooling water temperature of the vacuum calibrating unit can be monitoring controlled. ● Temperature profile displaying and auto alarm. ● The melting pipe extruder with auto temperature control, speed adjusting, temperature profile displaying and auto alarm functions. 　 　 　 MAIN TECHNICAL DATA Model Diam.
