2.How does the pressure system of a extrusion blow molding die design work?

We have a first -class management team, and we pay attention to teamwork to achieve common goals.
The pressure system of a blow molding machine is responsible for creating and maintaining the necessary pressure to inflate the parison (hollow tube of plastic) and shape it into the desired product. This system typically consists of three main components: the air compressor, the accumulator, and the pressure regulator.
1. Air Compressor: The air compressor is the heart of the pressure system. It supplies compressed air to the machine at a high pressure, typically between 100-150 psi. This compressed air is stored in a tank and then fed into the accumulator.
2. Accumulator: The accumulator is a large tank that stores the compressed air from the air compressor. It acts as a buffer, ensuring a steady supply of air to the machine. The accumulator also helps to regulate the pressure and flow of air to the mold.
3. Pressure Regulator: The pressure regulator is responsible for controlling the amount of air that is released from the accumulator into the mold. It is connected to the accumulator and the mold and is set to maintain a specific pressure level during the blow molding process.
The pressure system works in the following steps:
1. The air compressor compresses air and stores it in the accumulator tank.
2. The accumulator tank releases the compressed air into the pressure regulator.
3. The pressure regulator controls the flow of air into the mold, maintaining a specific pressure level.
4. The mold is closed and the parison is placed inside.
5. The mold is then clamped shut and the parison is inflated with the compressed air, taking the shape of the mold.
6. Once the plastic has cooled and solidified, the mold is opened and the finished product is ejected.
7. The pressure system continues to supply compressed air to the mold until the desired product is formed.
The pressure system is crucial in ensuring the quality and consistency of the blow molded products. It must be carefully monitored and maintained to ensure proper pressure levels are maintained throughout the process.

3.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.

4.Does a plastic blow dryer make PETG or Triton bottles?

Yes, the plastic blow molding machine of Leshan can make PETG and Triton bottles, and their blow molding machine can also make quadruple die heads.

5.How does the extrusion blow molding process differ from injection blow molding, and what types of products are typically produced using each method?

We have been working hard to improve service quality and meet customer needs.
Extrusion blow molding and injection blow molding are two different processes used to manufacture plastic products. While both methods involve melting plastic and shaping it into a desired form, there are some key differences between the two.
Extrusion blow molding is a process in which a molten tube of plastic, called a parison, is extruded through a die and then inflated to form a hollow product. The parison is then cooled and the mold opens to release the finished product. This process is commonly used to produce bottles, containers, and other hollow objects.
On the other hand, injection blow molding involves injecting molten plastic into a mold cavity, where it is then cooled and solidified. The mold then opens to release the finished product. This process is commonly used to produce small, complex, and precise products such as medical devices, pharmaceutical packaging, and small bottles.
One of the main differences between the two processes is the way the plastic is shaped. In extrusion blow molding, the plastic is shaped by the inflation of the parison, while in injection blow molding, the plastic is shaped by the mold cavity.
Another difference is the type of molds used. In extrusion blow molding, the molds are typically made of two halves that come together to form the desired shape. In injection blow molding, the molds are usually made of a single piece that is opened and closed to release the product.
The type of plastic used also differs between the two processes. Extrusion blow molding is typically used for high-density polyethylene (HDPE) and polyethylene terephthalate (PET) plastics, while injection blow molding is commonly used for polypropylene (PP) and polyethylene (PE) plastics.
In terms of product applications, extrusion blow molding is commonly used for larger, more simple products such as bottles and containers, while injection blow molding is used for smaller, more complex products such as medical devices and pharmaceutical packaging.
In summary, extrusion blow molding and injection blow molding are two different processes used to manufacture plastic products. While both methods involve melting plastic and shaping it into a desired form, they differ in the way the plastic is shaped, the type of molds used, and the types of products produced.
