7.How to control the energy consumption of blow extrusion molding?

We are a professional blow extrusion molding company dedicated to providing high quality products and services.
1. Use energy-efficient machines: When purchasing blow molding machines, opt for models that are energy-efficient and have a high energy star rating. These machines are designed to consume less energy while still maintaining high production efficiency.
2. Regular maintenance: Regular maintenance of the machines is crucial in controlling energy consumption. This includes cleaning and lubricating the machines, checking for leaks, and replacing worn-out parts. A well-maintained machine will operate more efficiently and consume less energy.
3. Optimize production processes: Analyze the production processes and identify areas where energy consumption can be reduced. For example, reducing the amount of air pressure used in the blowing process can significantly reduce energy consumption.
4. Use energy-saving features: Many blow molding machines come with energy-saving features such as automatic shut-off, idle mode, and variable speed drives. These features can help reduce energy consumption when the machine is not in use or operating at a lower speed.
5. Monitor energy usage: Install energy meters to monitor the energy consumption of the machines. This will help identify areas where energy is being wasted and allow for adjustments to be made to reduce consumption.
6. Use energy-efficient materials: The type of material used in the blow molding process can also affect energy consumption. Opt for materials that require less energy to heat and mold, such as lightweight plastics.
7. Implement energy management systems: Consider implementing an energy management system that can track and analyze energy usage in real-time. This will help identify patterns and areas for improvement.
8. Train employees: Proper training of employees on the operation and maintenance of the machines can help reduce energy consumption. They should be aware of energy-saving practices and encouraged to follow them.
9. Turn off machines when not in use: Make it a practice to turn off the machines when they are not in use, such as during breaks or at the end of the day. This will help save energy and reduce unnecessary wear and tear on the machines.
10. Regularly review and update energy-saving strategies: Regularly review and update your energy-saving strategies to ensure they are still effective. As technology advances, new energy-saving techniques may become available, so it is essential to stay informed and make necessary changes.

8.Why does the temperature of the barrel exceed the set value when the extruder blow molding machine is working fully automatically?

Extrusion requires accurate control of the temperature of each area. The heat comes from the heating element on the one hand, and the internal shear heat on the other. So, you want to check whether the fan is broken, or the screw does not adapt to the plastic you choose, need to change the plastic or need to change the screw.You can also ask questions on Leshan's website, and their technicians can respond to your questions.

9.How to design the shaping mold for blow extrusion molding?

We continuously upgrade our skills and knowledge to adapt to changing blow extrusion molding market needs.
1. Determine the shape and size of the final product: The first step in designing a shaping mold for blow molding machines is to determine the shape and size of the final product. This will help in determining the overall dimensions and features of the mold.
2. Choose the type of blow molding machine: There are different types of blow molding machines such as extrusion blow molding, injection blow molding, and stretch blow molding. Each type requires a different type of mold design, so it is important to choose the right type of machine for your product.
3. Create a 3D model of the product: Using CAD software, create a 3D model of the product to be molded. This will help in visualizing the final product and identifying any potential design issues.
4. Determine the number of cavities: The number of cavities in the mold will depend on the production volume and the size of the product. More cavities will increase the production rate, but it will also increase the complexity and cost of the mold.
5. Design the core and cavity: The core and cavity are the two main components of the mold. The core is the inner part of the mold that shapes the product, while the cavity is the outer part that gives the product its final shape. The design of these components should be precise and accurate to ensure a high-quality product.
6. Consider draft angles: Draft angles are important in blow molding as they allow the product to be easily removed from the mold. A draft angle of 3-5 degrees is recommended for most products.
7. Add cooling channels: Cooling channels are essential for maintaining the temperature of the mold during the molding process. These channels should be strategically placed to ensure uniform cooling and prevent warping of the product.
8. Include ejection system: An ejection system is used to remove the product from the mold after it has been formed. This can be in the form of pins, air blasts, or mechanical ejection systems.
9. Test and refine the design: Once the initial design is complete, it is important to test it on a prototype mold to identify any design flaws or issues. This will help in refining the design before the final mold is produced.
10. Consider material selection: The material used for the mold should be able to withstand high temperatures and pressures. Common materials used for blow molding molds include aluminum, steel, and beryllium copper.
11. Work with a professional mold maker: It is recommended to work with a professional mold maker who has experience in designing molds for blow molding machines. They can provide valuable insights and ensure that the mold is designed to meet your specific requirements.
