Physical Foaming Extrusion Line

1.Application

This machine suitable for CATV, RG series coaxial cable physical foaming insulation extrusion

2. Main parameter of Physical Foaming extruder

• Extrude 100% plasticization PE for coaxial conductor physical foaming
• Integrated electric control via frequency inverter and PLC
• Tension adjusted by moving hammer's location, detected by mechanical lever angle
• Plasticizing level: 75%
• Max. line speed: 150mpm (depend on outer dia.)
• Extrusion capacity: 120kg/hr
• Inner conductor dia.: Φ0.8~2.0mm
• Outer core dia.: Φ3.0~14.0mm
• Central height: 1000mm

• The physical foaming extrusion line for coaxial cable with PE insulation.
• With self-centering crosshead ensure good cable quality and easy operation.
• Crosshead with bypass unit for minimum crape material during start, save material cost.
• With dual payoff and accumulator, non-stop production during change take-up bobbin.
• Excellent tension control from start to end, ensure constant cable OD.
• Precise nitrogen gas injection and special design for screw, ensure polyethylene foaming degree as requirement.
• PLC control system, line speed, batch production count, cable OD, RPM etc. set and monitor on touch screen, easy operation.
• “All-in-one” button, cable OD keep stable while speed acceleration or deceleration, easy operation.
• Equipped with capacitance tester, laser gauge, spark tester, integrated into PLC control system, ensure top cable quality and high productivity.
