6.How does the pressure system of a extrusion blow molder 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.
