Product Description
This semi automatic PET bottle blowing machine is designed for small- to medium-scale PET bottle production, supporting PET containers from 0.1L to 2L. It is suitable for producing bottles used for mineral water, carbonated drinks, edible oil, cosmetics, pesticides and other liquid products.
The machine uses a double-crank mold adjustment system and heavy-duty clamping structure to provide stable mold closing during the bottle blowing process. The infrared heating oven heats PET preforms while rotating them, helping achieve more uniform preform heating before stretching and blowing.
The pneumatic system is divided into the pneumatic drive section and bottle blowing section to meet the different air requirements of machine operation and PET bottle forming. The high-pressure air system provides the compressed air required for bottle blowing, while the integrated air dryer and filter can help prepare the compressed air before it enters the blowing process.
The machine supports both stepping operation and semi-automatic operation, making it suitable for customers who need a relatively simple operating process and flexible production control.
With its compact structure, relatively low equipment investment and straightforward operation, this semi automatic PET bottle blowing machine is suitable for beverage producers, packaging manufacturers and other businesses producing PET containers in different bottle sizes and shapes.
Features
100ml–2L PET bottle production: Suitable for producing a range of PET containers from 0.1L to 2L.
Semi-automatic operation: Supports stepping and semi-automatic operating modes for flexible production control.
Uniform preform heating: The infrared heating oven rotates the preform during heating to improve heating uniformity before blowing.
Heavy-duty clamping system: The double-crank mold adjustment structure provides stable mold clamping during bottle forming.
Stable pneumatic system: Separate pneumatic and bottle blowing air circuits help meet different operating and blowing requirements.
High-pressure air support: The machine can be configured with a high-pressure air compressor for PET bottle blowing.
Compressed air treatment: The air dryer and filter help remove moisture and impurities from compressed air before the blowing process.
Compact equipment design: The machine is suitable for production environments where equipment space and initial investment need to be controlled.
Flexible bottle production: Different PET bottle shapes can be produced by changing the bottle mold within the applicable machine specifications.
PET Bottle Blowing Process
The PET bottle production process generally consists of the following stages:
PET preform preparation – PET preforms are prepared according to the required bottle size and neck specification.
Preform heating – The preform passes through the infrared heating oven and is heated evenly while rotating.
Mold positioning – The heated preform is transferred into the bottle mold.
Mold clamping – The clamping system closes and secures the mold during the blowing process.
Stretching and blowing – Compressed air is introduced to expand the heated PET preform against the mold cavity.
Bottle forming – The PET material takes the shape of the mold to form the finished bottle.
Mold opening and removal – After forming, the mold opens and the finished PET bottle is removed for the next production stage.
