The production process of PVC slotted pipe
1. Raw material mixing: PVC stabilizer, plasticizer, antioxidant and other auxiliary materials are added into the high-speed mixer according to the proportion and process. Set the process temperature, and then reduce the material to 40-50 degrees through the cold mixer; in this way, it can be added to the hopper of the extruder.
2. Cutting machine: After the stroke switch is controlled according to the required length, it will automatically cut, and delay the turning frame, and implement flow production. The cutting machine uses the fixed-length switch signal as an instruction to complete the entire cutting process, and runs with the pipe during the cutting process. Keep in sync, the cutting process is completed by electric and pneumatic drive. The cutting machine is equipped with a dust suction device to suck out the cutting debris in time and recover it.
3. Extrusion die head part: the PVC that is compacted, melted, mixed and homogenized, and the subsequent materials are pushed to the die head by the screw. The extrusion die head is a key part of the pipe forming.
