Types of PET bottle blow-moulding machines

The PET bottle blow-moulding machine is an essential part of PET bottle production. It’s used to take the preforms and blow them into the shape of the desired bottle. Several different types of these machines exist to cater to various industries and their needs.

• Injection Blow Moulding:

  This machine works in three steps. Firstly, the molten plastic is injected into a metal mold. Next, the metal mold is moved to another area where hot air blows into the preform, shaping it into the desired container. Lastly, the metal mold cools down, and the container is removed. Injection blow-moulding machines can produce containers with complex geometries. They can also be used to manufacture containers with integrated handles or other attachments.

• Extrusion Blow Moulding:

  An extrusion blow-moulding machine works a lot like the injection blow-moulding machine, except for one key difference. Instead of injecting molten plastic into a mold, the machine forces it through a die and then into a mold. This machine is cost-effective and best used in high-production environments. It is suitable for producing simple bottles without intricate designs.

• Injection Stretch Blow Moulding:

  This machine first injects molten PET into preforms. Once the preforms are cooled, the machine blows air into them while simultaneously stretching them vertically. This method enhances the strength of the bottle, making it suitable for carbonated drinks.

• Half Blow Moulding:

  Half-blow moulding machines make use of a hybrid technique. They make use of an injection method to create the preform but use a stretch-blow technique to expand the preform into the mold. These machines have greater efficiency than traditional methods and are suited for creating PET bottles with more shape and higher clarity. They may not be ideal for large production activities where speed is essential, though.

Specifications and maintenance of PET bottle blow moulding machine

The specific requirements will depend on the type and capacity of the PET bottle blow moulding machine being used. Here are some specifications corresponding with some of the popular machine types:

• Capacity/Output: The capacity or output is usually given in the number of bottles produced per hour. For example, high-speed automatic PET bottle blow moulding machines may have capacities ranging from 1,000 to 4,000 bottles per hour for a 500ml bottle.
• Power Consumption: The power consumption will depend on the wattage of the blowing air compressor used along with the blow moulding machine. It may range from 15 kW to 50 kW, depending on the machine's size.
• Dimensions: The overall dimensions of the blow moulding machine may vary from 1m to 2m in length with about 2m height. The exact dimensions would depend on the specific type of the blow moulding machine (such as linear or rotary).
• Material Compatibility: The material is of the machine is made and that of the moulds used for it, must all effectively bear the high heat and pressure conditions required for blowing PET. The materials used will have mould and corrosion resistance capabilities.
• Control System: This system's interfaces and features dimensions will differ if it is manual, semi-automatic, or fully automatic. For example, a machine with a fully automatic control system may have an HMI touch screen of 12" with recipe management and bottle shape parameters, amongst other things.

The blow moulding machine will have to be inspected and serviced periodically to keep it in good working condition. Certain specific maintenance tasks such as oiling, greasing, or cleaning are also required on a frequent basis. The routine maintenance spares most blow moulding machines from requiring any major repair.

• Daily Maintenance: Blow moulding machines must be cleaned every day by flushing the system and removing any residue left in the heating circuit, air circuit, and water circuit. Proper drying and blow-out should be done. All the filters should also be checked, and any clogged ones should be cleaned or replaced. Fasteners and fittings should be checked, and their tightening should be ensured. Any electrical connections that are exposed or loose should be checked and secured properly.
• Weekly Maintenance: A detailed inspection of the entire machine should be carried out each week, including the blow mould, clamp mechanism, heating assembly, air supply system, conveyor system, and any other components. All moving parts should be lubricated with high-grade oil or grease, including chains and rollers. Critical areas where the lubricant dries up or is depleted should be checked more frequently. The air compressor system operating with the blow machine should also be inspected with drain water collected in the air receiver done on a daily basis.
• Monthly Maintenance: Complex parts of the system, such as the clamping cylinder, blowing air system, etc., may need greasing or oiling to be done, including the gearboxes, locking mechanisms, linear guides, guide rails, etc., as specified under the manufacturer's instruction manual. The entire electric panel and all electric wires must be inspected to ensure that no loose fittings or signs of wear and tear is present. The water filter must also be inspected, and if any contaminants are found, they should be cleaned or flushed out.
