2.How to adjust the production speed of extrusion blow molding mandrel?

Our extrusion blow molding mandrel products undergo strict quality control to ensure customer satisfaction.
1. Check the machine settings: The first step in adjusting the production speed of a blow molding machine is to check the machine settings. Make sure that the machine is set to the desired production speed and that all the necessary adjustments have been made.
2. Adjust the air pressure: The air pressure is a crucial factor in the production speed of a blow molding machine. Increasing the air pressure can help to speed up the production process, while decreasing it can slow it down. Adjust the air pressure according to the desired production speed.
3. Change the mold: The size and shape of the mold can also affect the production speed. A larger or more complex mold will take longer to produce, while a smaller and simpler mold will speed up the production process. Consider changing the mold to one that is more suitable for the desired production speed.
4. Increase or decrease the parison size: The parison is the hollow tube of plastic that is formed in the machine and then blown into the mold. Adjusting the size of the parison can also affect the production speed. Increasing the parison size will result in a larger product and slower production, while decreasing the parison size will result in a smaller product and faster production.
5. Adjust the cooling time: The cooling time is the amount of time the product spends in the mold to solidify. Increasing the cooling time will slow down the production speed, while decreasing it will speed it up. Adjust the cooling time according to the desired production speed.
6. Check for any mechanical issues: If the production speed is not adjusting as expected, it is important to check for any mechanical issues with the machine. Make sure that all the components are functioning properly and that there are no obstructions or malfunctions that could be slowing down the production speed.
7. Test and adjust: Once all the necessary adjustments have been made, run a test production to see if the desired speed has been achieved. If not, make further adjustments until the desired production speed is reached.
It is important to note that adjusting the production speed of a blow molding machine may require some trial and error. It is recommended to make small adjustments at a time and test the results before making further adjustments.
