JL45D extrusion line can produce various types of PVC Slider zipper profiles by changing its mould, which can be designed according to your samples or specific requirements.

This extrusion line consists of Chiller, main extrusion part, die head, automatic filter changer system, die plate, water tank (form the zipper at constant temperature), dehydrating system and air-drying unit with Vacuum blower, zipper traction part, auto zipper-closing part and zipper rewinding unit.
The die plate of zipper can be designed according to customers’ sample or drawing.

• The die head for the zipper extruding device employs advanced 90° extrusion.
• The charging barrel and screw of our PVC zipper extruder are produced from high quality alloy steel with chrome plating, based on the special demand of the material flow rate during production. Therefore, it has strong resistance to abrasion, heat and deformation.
• It is equipped with stainless steel storage tank.
• The PVC zipper production line produces zipper with superior quality, by virtue of the employment of Panasonic frequency converters, well-known hard tooth face speed reducer, and the torque motor reeling machine. In addition, the productivity is improved, as well.
• For consistent quality, this range of high speed zipper extruding machine is offered with water cooling tank to provide constant temperature for zipper cooling.
• Air plug is used for power supply connection.
• The band heater for the charging barrel is produced with stainless steel surface, and independent air blower for cooling. The inside is made of porcelain heater.
• For easy disassembly and maintenance, the mould is engineered with one-piece filter screen.
• The winding device for the PVC zipper extruder is conducive to the improvement of zipper quality and productivity.
• The live roller for the front and back traction apparatus employs two turbine decelerating motors to control the motor speed through group frequency. (The front end of the live roller is connected by belt. In addition, the cycloidal pinwheel speed reducer is adopted, as well).
• It uses stainless steel plate for the surface of the worktable.
• Aside from the attractive appearance, this PVC zipper extruder is well received due to the easy operation.
