What is PET Bottle Blowing Molding Machine?

PET bottle Blowing molding Machine is an ideal equipment to blow various bottles, such as mineral water, carbonated drinks, hot-filling products, and cosmetics. It is a semi-automatic machine with PLC controller which provides time control precision up to 0.01 second and also adopts reliable designed three-plate toggle clamping system to ensure powerful clamping force.

The basic structure of this automatic PET bottle blow molding machine consists of heating oven, batcher for orientation and preform feeding and compressor equipment. The compressor is the heart of the system, feeding pneumatics that provide high-pressure compressed air for bottle blowing.

Oil-free Compressors for PET Blow Molding
For the PET bottle blow molding process, many plant engineers have learned that choosing the right type of compressor can make a huge difference to energy costs and overall plant profitability. As a result, a number of new oil-free models are available for this purpose and they include a recovery system that allows the pressure to be recycled back through the compressor.

Energy Saving and Line Efficiency
As PET production has grown in scale, plant engineers have come to realise that they are using a lot of energy. A large percentage of this is consumed by the compressors.

Reciprocating piston compressors are the most common model found in PET bottle manufacturing, but centrifugal compressors are also becoming more and more popular. These are less energy-intensive than reciprocating models and they also require fewer inbuilt parts.

In addition to this, many new machines are now equipped with an air recovery system. This allows a certain amount of the pressure that is produced during the high blow cycle to be recycled back through the compressor. This helps to reduce operating costs, especially for plants with a high number of compressors.
