The process sequence of producing rigid plastic pipes by pvc pipe extrusion machine is: batching according to the pipe material formula one → raw material mixing → extrusion plasticizing and granulating → extrusion plasticizing → cooling and shaping → traction → cutting → quality inspection → measuring and packaging → finished product Inventory.
What are the main features of pvc pipe extrusion machine?
What are the process parameters of pvc pipe extrusion machine?
What are the production characteristics of pvc pipe extrusion machine?
1. The soft plasticizing concept runs through the screw design of the pvc pipe extrusion machine, which provides a strong guarantee for the high-speed extrusion of PVC pipes.
2. The two-stage screw core external circulation temperature control system that can be used by the pvc pipe extrusion machine ensures that different formulations can produce high-quality UPVC pipes.
3. The efficiency of pvc pipe extrusion machine is high. Low noise air cooling system, reliable and effective vacuum exhaust system, high precision, wide speed regulation, forced quantitative feeding system, high performance deceleration torque distribution gearbox, perfect and accurate temperature automatic control system, accurate and stable speed regulation system.
The extrusion process parameters of pvc pipe extrusion machine include temperature, pressure, extrusion speed, pulling speed, etc.
1. Temperature: Temperature is one of the important conditions to ensure the smooth progress of the extrusion process of the pvc pipe extrusion machine.
2. Pressure: During the extrusion process of the pvc pipe extrusion machine, due to the sticky tape of the melt, the change of the depth of the screw groove, and the obstacles caused by filtration and die, etc., the axis direction of the raw material barrel and the inside of the melt establish a certain pressure. pressure.
3. Extrusion speed: The extrusion speed of pvc pipe extrusion machine refers to the amount of plasticized material or the length of plastic parts extruded from the extruder and the die in unit time, which represents the level of production capacity of the extruder.
4. Traction speed: pvc pipe extrusion machine extrusion molding mainly produces plastic products with continuous length.
Temperature control: There are many plasticizers in the hose PVC pipe formula, the melt viscosity is small, the fluidity is good, and the molding temperature is low.
Screw cooling: The screw that produces the soft pvc pipe generally does not need cooling.
Screw speed: When producing transparency, increasing the speed can improve the transparency.
Traction speed: The traction speed of the soft PVC pipe is faster, and the production of thin-nosed and small-diameter pipes makes the traction speed of the pvc pipe extrusion machine more than twice as fast as the extrusion speed. The pvc pipe extrusion machine does not need to add compressed air, but the air inlet of the machine head still needs to be connected to the atmosphere to make the pressure in the pipe equal, otherwise the pipe will not be round or even flattened.
