he pvc resin powder is mixed with a plasticizer to form pvc particles. We melted the pvc particles. The melted liquid is then extruded by the first extruder through mould to form the inner layer of the pvc hose.
We use water to cool pvc hose inner layer and it is conveyed to the woven machine by the first tractor.
The polyester yarn is then woven around the inner layer of the pvc hose. Then dry the water on the hose by oven. After then pvc particles are then heated, melted again, and extruded by the second extruder through a mould onto the fibrous layer, thus forming the outer layer of the pvc hose.
We also need to cool the pvc hose as it's surface is too hot now. So it is conveyed to the cooling frame by the second tractor.
The prodcution process is finished after we do all of this.
