Extrusion Blow Mold

1.How to solve the malfunction of the extrusion blow mold?

As one of the top extrusion blow mold manufacturers in China, we take this very seriously.
1. Check the power supply: Make sure the machine is properly connected to a stable power source. If there is a power surge or fluctuation, it can cause the machine to malfunction.
2. Inspect the air supply: The blow molding machine requires a steady supply of compressed air to function properly. Check the air compressor and make sure it is providing enough pressure and volume.
3. Check the temperature settings: The temperature of the machine's heating elements must be set correctly for the plastic to melt and form properly. Make sure the temperature settings are appropriate for the type of plastic being used.
4. Clean and lubricate the machine: Over time, dust, debris, and residue can build up on the machine, causing it to malfunction. Clean and lubricate all moving parts to ensure smooth operation.
5. Check for worn or damaged parts: Inspect all parts of the machine for wear and tear. Replace any damaged or worn parts to prevent further malfunctions.
6. Adjust the mold: If the product being produced is not forming correctly, the mold may need to be adjusted. Make sure the mold is properly aligned and tightened.
7. Consult the manual: If the above steps do not solve the problem, consult the machine's manual for troubleshooting tips and solutions specific to your machine.
8. Call a professional: If the problem persists, it may be best to call a professional technician to diagnose and repair the machine. Attempting to fix complex issues without proper knowledge and training can cause further damage.

4.How to choose the mold head of a extrusion blow mold?

We pay attention to the introduction and training of talents, scientifically regulate the management system, and focus on cultural construction and team cohesion.
1. Determine the type of blow molding machine: The first step in choosing the mold head is to determine the type of blow molding machine you have. There are three main types of blow molding machines: extrusion blow molding, injection blow molding, and stretch blow molding. Each type requires a different type of mold head.
2. Consider the material: The material you will be using for your product is also an important factor in choosing the mold head. Different materials have different properties and require different mold heads. For example, if you are using a high-density polyethylene (HDPE) material, you will need a mold head with a larger opening to accommodate the material's higher melt flow rate.
3. Determine the shape and size of the product: The shape and size of the product you want to produce will also play a role in choosing the mold head. The mold head needs to be able to create the desired shape and size of the product. If you are producing a complex shape, you may need a mold head with multiple cavities or a custom-made mold head.
4. Consider the production volume: The production volume also needs to be taken into account when choosing the mold head. If you are producing a large volume of products, you may need a mold head with multiple cavities to increase production efficiency.
5. Check the compatibility with the machine: It is important to ensure that the mold head you choose is compatible with your blow molding machine. The mold head needs to fit securely and work seamlessly with the machine to produce high-quality products.
6. Look for quality and durability: The mold head is a crucial component of the blow molding process, and it is important to choose one that is of high quality and durable. Look for mold heads made from high-quality materials and with a good track record of performance.
7. Consider the cost: The cost of the mold head is also an important factor to consider. While it is important to choose a high-quality and durable mold head, it is also important to stay within your budget. Compare prices from different suppliers and choose one that offers a good balance of quality and cost.
8. Consult with experts: If you are unsure about which mold head to choose, it is always a good idea to consult with experts in the field. They can provide valuable insights and recommendations based on your specific needs and requirements.

7.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.
