Air Compressors for PET Bottling Industry

Air Compressors for PET Bottling Industry

Air compressors play a significant role in the PET Bottling Industry by ensuring the smooth and efficient production of plastic bottles. One of their primary functions is in the bottle-blowing process. The small, thick-walled plastic tubes are heated and then inflated using compressed air. This controlled inflation process allows the preforms to take on the desired bottle shape. Without a reliable source of compressed air, this critical step in bottle production would be impossible, leading to production delays and losses.

Also, PET bottling air compressors are used for cleaning and drying bottles before filling them with beverages or other products. This process maintains the cleanliness and quality of bottles. These compressors power pneumatic conveyor systems which efficiently transport bottles from one stage of production to another, contributing to the overall productivity and automation of the bottling process. Without compressed air, the movement of bottles along the production line would be less efficient and more labour-intensive.

Bimpex, a leading industrial air compressor supplier, offers a diverse selection of air compressors designed to meet the various needs of the PET Bottle industry.

A] Types of Air Compressors In The PET Bottling Industry And Their Usage

High Pressure Reciprocating Air Compressors

The compressors are used to provide high-pressure compressed air for blowing bottles depending on the container’s design, wall thickness, blow speed, and other factors. The reciprocating air compressors operate by using pistons to create pressure within the cylinder. They are essential for achieving air pressures exceeding 650 psi, especially for intricate product designs. The heart of reciprocating air compressors lies in the principle of reciprocating motion, where the piston alternates back and forth in the cylinder, ensuring consistent and reliable compression for diverse industrial applications, including bottle production.

Screw Air Compressors

Unlike reciprocating compressors, which produce pulsating air output, screw compressors offer a consistent and seamless flow of compressed air. This steadiness is critical for consistent bottle quality during the blowing process as it ensures uniform bottle quality with every cycle.

Additionally, screw compressors are energy-efficient, and their ability to maintain a stable air pressure, coupled with advanced control systems, minimises energy consumption, ultimately reducing operational costs for bottling plants. The compact design and low noise level of screw compressors make them a practical choice for bottling facilities. Their small footprint allows for efficient use of space, and their quiet operation fosters a more comfortable working environment for plant operators.

B] Application Of Air Compressor For PET Bottling Industry

Bimpex’s Anest Iwata air compressor serves a critical role in the glass industry in various applications. High-quality glass air compressors are an essential component for the smooth operation of glass manufacturing companies worldwide. Here are some of the key applications of Bimpex’s air compressor in glass industry:

Bottle Blowing: The small, thick-walled plastic tubes are heated and then inflated using compressed air. High-pressure compressed air is used to blow and shape bottles. Generally, stretch blow moulding requires about 10~25 bar for pre-blowing and about 40 bar for the bottle-blowing process.

Cleaning Air and Drying Bottles: Oil-free compressed air system in PET bottling industry is used for cleaning bottles before they are filled with water, beverage or cooking oil. This process maintains cleanliness and ensures the air is not contaminated. Because if it is, it will influence the flavour and odour, causing health problems.

Powering pneumatic conveyor systems: Air compressors power pneumatic conveyor systems which efficiently transport bottles from one stage of production to another, contributing to the overall productivity and automation of the bottling process.

Packaging and Labelling: Compressed air in PET bottling industry is used to control the valves and actuators in automated lines, transport empty bottles, and apply labels to bottles. Without a reliable source of compressed air, the packaging and labelling process would be less efficient and more labour-intensive, leading to production delays and losses.

D] PET Bottling Air Compressor FAQ's

Cost can vary depending on several factors, including the size of the system, the type of compressor, and the energy efficiency of the system. Please reach out to us with your specific requirements, and we will provide you with a cost estimate accordingly.

There are various factors to consider when determining the air consumption such as bottle design, blow machine air pressure, and energy-efficient practices to reduce operating costs.

Begin by considering factors like flow requirements, adherence to standards, pressure drop calculations, material and stress ratings, and any plastic piping challenges. This assessment will help you choose the right sizing for your system.

The requirements can vary depending on specific system and production needs. Several factors influence this need such as:

  • Heat Set PET: Cooling prevents deformity by solidifying preforms heated to 100-110°C.
  • Injection Moulding: Cooling solidifies plastic pellets moulded into preforms.
  • Compressed Air: Compressors stay cool during PET preform blowing.
  • Functional Properties: Meeting container standards ensures quality.
  • Class 0 Compressors: They provide clean air for process reliability and a good reputation.
