2.How to design the shaping mold for bottle extrusion blow moulding machine?

We continuously upgrade our skills and knowledge to adapt to changing bottle extrusion blow moulding machine 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.

3.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.

6.What is a blow molding machine?

We maintain a stable growth through reasonable capital operations, focus on industry development trends and cutting -edge technologies, and focus on product quality and safety performance.
A blow molding machine is a manufacturing machine used to produce hollow plastic parts or containers by inflating a heated plastic tube or parison inside a mold until it takes the shape of the mold cavity. The process involves melting plastic resin and extruding it into a hollow tube, which is then clamped into a mold and inflated with compressed air until it conforms to the shape of the mold.
This process is commonly used to produce bottles, containers, and other hollow plastic products. Blow molding machines can be either extrusion blow molding machines or injection blow molding machines, depending on the method used to create the parison.

7.What is the difference between traditional bottle extrusion blow moulding machine and fully computer-controlled blow molding machines?

We have the leading technology and innovation capabilities, and attach importance to employee training and development, and provide promotion opportunities.
Traditional blow molding machines are operated manually by a person, while fully computer-controlled blow molding machines are operated by a computer program. This means that traditional blow molding machines require more human labor and supervision, while fully computer-controlled machines can run automatically with minimal human intervention.
Additionally, traditional blow molding machines may have limited capabilities and may only be able to produce simple shapes, while fully computer-controlled machines can produce more complex and precise shapes. This is because the computer program can control the machine's movements and parameters with greater accuracy and consistency.
Furthermore, fully computer-controlled blow molding machines often have advanced features such as real-time monitoring, data collection, and automatic adjustments, which can improve efficiency and quality control.
Overall, the main difference between traditional blow molding machines and fully computer-controlled machines is the level of automation and precision in the production process.

9.What is the working principle of a blow molding machine?

We focus on innovation and continuous improvement to maintain a competitive advantage.
The working principle of a blow molding machine involves the use of compressed air to inflate a molten plastic tube or parison inside a mold cavity. This creates a hollow shape that is then cooled and solidified to form a plastic product.
The process begins with the plastic material, usually in the form of pellets, being fed into a hopper and then melted in an extruder. The molten plastic is then forced into a long tube or parison, which is then clamped between two halves of a mold.
Next, a nozzle is inserted into the parison and compressed air is blown into it, causing the plastic to expand and take the shape of the mold cavity. The mold is cooled to solidify the plastic, and then the mold halves are separated, and the finished product is ejected.
The blow molding process can be either extrusion blow molding or injection blow molding, depending on the type of machine used. In extrusion blow molding, the parison is formed by extruding the molten plastic through a die, while in injection blow molding, the parison is formed by injecting the molten plastic into a mold cavity.
The working principle of a blow molding machine is based on the principles of thermodynamics and fluid mechanics, where the expansion of compressed air inside the parison creates pressure that forces the plastic to take the shape of the mold. This process allows for the production of hollow plastic products with complex shapes and sizes.
