Customize Pre-Insulated Pipe Production Line,PLC computer system control

The HDPE Pressure Pipe Extrusion Line, crafted by HSD company through meticulous assimilation and mastery of advanced technologies sourced internationally, is a versatile system designed for the extrusion of various materials including PE, PP, PB, PERT, and ABS. This domestically produced PE pipe manufacturing line offers a formidable alternative to imported extrusion lines, demonstrating equal or superior performance.

This pipe extrusion line mainly includes single screw extruder, molds, vacuum calibrating water tank, spray water cooling tank, haul-off machine, cutting machine and bracket.

Plastic Pipes produced by this line have excellent stiffness, flexibility, high mechanical strength, resistance of environmental stress cracks, resistance to creep deformation, heat-linkage and so on. It has become the first choice for the city gas pipe, water supply pipe, foundation pipe, landfill collection pipe, watermain, geothermal heating etc.

Application
HDPE pipe extruding line composed of single screw extruder and corresponding auxiliaries, can produce all kinds of small diameter HDPE plastic pipes continuously. It also can be used to produce PS, PP, HDPE plastic pipes after replacing the screw. HDPE plastic pipe is widely used for liquid conveying in agricultural, chemical industry, construction industry, etc.
Structure
HDPE pipe extruding line is mainly composed of single screw extruder, die-head, vacuum forming tank, spray cooling tank, haul-off device, cutting device, and pneumatic discharging frame.

Single Screw Extruder
Single screw extruder is composed of AC motor, hard toothed surface reduction gear, extruding system, heating and cooling system, and electrical controlling part. AC motor transfer the power to reduction gearbox via V-belt wheel and make screw rotate at certain speed to adapt to extruding all kinds of plastics.

Die-Head
Die-head is mainly composed of mandril, neck mold, spiral body, cover, die-head body, bolts, and heating rings. The inside surface touching with plastic materials is polished and chrome plated to ensure plastic materials flow smoothly and to ensure no rusting. The uniformity of pipe wall thickness can be adjusted by bolts. The copper calibrating sleeve fixed in die-head is mainly used to cool down the fresh pipe and to calibrate the pipe outer diameter.

II. Machine Advantages
---High-efficiency extruder gives larger output, stable performance.
For example
SJ90/33---600-700kg/h
SJ120/33---800-900kg/h
SJ150/33---1000-1200kg/h
---Compared with inflating method (internal pressure method)
1. For 24 hours working, it reduces 2-3 workers for each shift.
2. There is much waste pipe and material, no need workers to crush waste material.
3. High-effeciency. Take Dimater 960mm as an example, Output is approximately 60 pcs of 11.6meters pipe, it is much higher output than that of inflating method.
4. Pipe wall is average and smooth, to reduce waste of raw material, and pipe thickness is adjustable.
5. No need trim edge, once forming.

III. Main machine- High-effeciency single screw extruder
---Single screw is with barreir & mixing head; Barrel is new model with slotting (channel), Both make security of good jellification, large output and stable performance.

IV. Controlling system
The complete line could be controlled by PLC, with good human-machine interface, all technical parameters could be set and indicated by touching screen. Controlling system is designed according to the customer; S requirement, to be with PLC, or without.

 Electrical system
---ABB frequency converter or EUROTHERM speed controller
---Japan RKC temperature controller
--- SIEMENS AC contactors
