The PPR pipe making machine typically consists of the following components: 1. Extruder: The extruder is the main component of the machine, responsible for melting and homogenizing the polypropylene resin. It consists of a barrel and a screw, which rotate to generate heat and pressure required for melting the resin. 2. Die head: The die head is responsible for shaping the molten resin into a pipe. It has a specific design to control the size and dimensions of the pipe being produced. 3. Cooling system: After the pipe is extruded from the die head, it needs to be cooled down to solidify. The cooling system usually includes water tanks or cooling fans to rapidly cool the pipe. 4. Haul-off unit: The haul-off unit is used to pull the pipe out of the machine at a constant speed. It consists of belts or caterpillar tracks that grip the pipe and move it forward. 5. Cutting unit: Once the pipe is pulled out of the machine, it needs to be cut into desired lengths. The cutting unit can be equipped with a saw or a guillotine cutter to achieve precise and clean cuts. 6. Control system: The machine is controlled by a control panel, which allows the operator to monitor and adjust various parameters such as temperature, speed, and pressure.
