Three extrusion line solutions for PVC edge banding

Mixer + PVC granulating machine + single screw extruder + printing machine: First you need mix raw material together by PVC mixer, second make granule by granulating machine, and then Use single screw extruder(SJ45 or SJ65 single screw extruder) to get edge band, then use printing machine to get glossy surface or wooden design and etc.
Mixer + Double screw extruder + printing machine: First mix raw material together by mixer, and the use double screw extruder(SJSZ51/105 or SJSZ55/110) to produce egde band, final step is to print color or make edge band glossy.
Three calender system + printing machine + cutting machine: First mix raw material, and then use three calender system to produce big width edge band sheet, and then print colors on the edge band, finally, cut pvc edge band sheet into specific width like 19mm, 20mm etc.

Plastic Extruder:

Process: The screw conveys, compresses, melts (plasticizes), and homogenizes the PVC compound through zones with increasing temperature profiles.
Temperature Control: Precise heating (electric bands) and cooling (water jackets) along the barrel are critical for consistent melt quality and preventing degradation.

Extrusion Mould:

Mounted directly onto the end of the extruder barrel.
Shaped to form the molten PVC into the specific profile of the edge band (common profiles: T-molding, D-molding, V-groove, square, flexible rounded).
Precision machining is vital for dimensional accuracy and surface finish.

Cooling Tank:

Long water baths (spray or immersion) continue the controlled cooling process to ensure the profile is fully set and dimensionally stable before handling. Multiple tanks are common.

Haul-off Unit:

A set of motor-driven rubber or textured belts or caterpillar tracks that grip the cooled profile.
Provides constant, controlled tension to pull the profile continuously through the die, calibrator, and cooling tanks. Speed is synchronized with the extruder output.

Winder:

For flexible PVC edge bands (most common type).
Winds the continuous band into large, uniform coils or spools for packaging and shipment. Tension control is critical to avoid stretching or deformation.
