● The machine has been developed to conduct 24 hours continuous operation and ensure the stability of the whole process, showing excellent performance in performance and reliability.

● Machine runs steady, safe and secure.

● The PLC centralizes control in a single location and is capable of integrating several points of operation into one control system. This can be beneficial in many ways: It reduce costs, reduces down time and provides greater flexibility, including remote monitoring capability.

● Our low thermal profile makes it an excellent choice for high-pressure, high-temperature applications that require minimal heat transfer, such as beverage and dairy bottle filling machines.

Gears and Bearings

Gears and bearings are components designed to provide longer operational lifespans. They work together in a system, with the gears transferring power from one shaft to another and the bearing providing support so that the other parts can move or stay still as needed.

Compression Cycle

The compression cycle only has four major rotating components. These parts work together to convert the energy released in fuel combustion into mechanical energy that is then used to power cars and other machines.

Backward Inclined Impeller

A backward inclined impeller is a type of fan blade designed to maximize efficiency and regulate airflow range. It features an inclined surface, which helps capture more air than traditional blades and generate higher pressure, allowing it to be used in a wider range of applications.

Pipeline

Pipelines are an efficient way to attach multiple components of a system together. They occupy minimal space and make installation much simpler as the number of connections is reduced.

Frequently Asked Questions

Why is compressed air important for PET bottle blowing?

Compressed air is essential for the PET bottle blowing process as it provides the force needed to expand and shape the PET preforms. Without compressed air, it would be impossible to create PET bottles.

For example, single-stage compression screw machine rotor: the pressure at the inlet end is about 1 bar of atmospheric pressure, compressed by the rotor to an outlet pressure of 8 bar, the compression ratio of the compression process is 8/1, that is, the single-stage compressor compression ratio of 8. While the pressure at the inlet end of the dual-stage is about 1 bar of atmospheric pressure, compressed by the first-stage rotor to an outlet pressure of about 3 bar, and then into the second-stage rotor compression to enhance the pressure to the required 8 bar The compression ratio of the first stage low pressure rotor is about 3, and the compression ratio of the second stage high pressure rotor is 8/3 ≈ 2.67, i.e. the compression ratio of the second stage is about 2.67. The maximum compression ratio of the two-stage compression rotor system is about 3.

How does a PET Blow Molding Air Compressor work?

The most common type of PET Blow Molding Air Compressor is the reciprocating piston compressor. It draws in atmospheric air through suction valves and compresses it by moving the piston back towards the cylinder head. The compressed air is then cooled before being used in the PET bottle blowing process.

What is the required air pressure for PET bottle blowing?

The required air pressure for PET bottle blowing depends on the bottle’s design and wall thickness. Generally, the process works with a pressure of 10-25 bar for pre-blowing and a maximum of 40 bar for the bottle blowing process. Thicker walls and complex shapes may require higher pressures.
