Machine Introduction&Features

The semi-automatic blow molding machine consists of two key components: the Bottle Blower and the Infrared Preform Oven. The Infrared Preform Oven functions to heat the PET preform to the optimal softness required for the subsequent blowing process.

The Blower is responsible for carrying out the entire bottle blowing process, which includes sealing, stretching, blowing, exhausting, and controlling the movement of the blow mold via an advanced PLC control system. The machine’s Patent Blow Air Heating System and Pre-blow Function are crucial for achieving high-quality bottles and eliminating the unsightly whitening effect that can occur.

Wide-capacity range PET bottle production

Wide application range, capable of producing PET bottles with capacities ranging from 50ml to 20L, in various shapes and sizes.

Easy operation

Microcomputer automatic control, for easy operation.

Pre-blowing improves PET bottle quality

Pre-blowing function, which enhances the quality of PET bottles and reduces the reject rate.

Advanced air path design

Advanced air path design, with single or dual inlet options, low-pressure mechanical clamping, sealing, stretching, and high-pressure blowing.

Precise infrared preform heating

Infrared heating of the preform, with independent control of each layer, variable frequency speed regulation, and cold air cooling of the bottle mouth, resulting in the best blowing accuracy.

Modular design for easy maintenance

Modular design for easy maintenance and repair.

Our Equipment Usage

Product Details

  Name Description
High Pressure Air Compressor A high pressure air compressor is an essential component in the blow molding process as it is used to generate and maintain the high pressure required to shape the plastic material into the desired mold shape.
Low Pressure Air Compressor A low pressure air compressor is also an important component in the blow molding process, as it is used to supply the compressed air required to inflate the plastic material into the desired shape.As with high pressure air compressors, it is recommended to consult with a professional in the field of compressed air systems to help determine the best low pressure air compressor for your specific blow molding application.
Air Purify System An air purifying system is an important component of a blow molding machine as it is used to clean and purify the compressed air before it is used in the blow molding process
Water Chiller A water chiller is an important component in the blow molding process as it is used to cool the mold and the plastic material during the blow molding process. The use of a water chiller is important as it helps to ensure that the plastic material maintains its desired shape and quality.


The process starts by melting plastic resin and then injecting it into a mold. Once the plastic has cooled and solidified, a hollow tube called a parison is formed. The parison is then clamped into a mold and air is blown into it, causing it to expand and take on the shape of the mold.

There are several types of blow molding machines, including extrusion blow molding machines, injection blow molding machines, and stretch blow molding machines.

High production efficiency, the ability to produce large quantities of products with consistent quality, and the ability to create complex shapes and designs.
It can work with the thermoplastic materials, including HDPE, LDPE, PP, PVC, PET, and others.
