Machine Introduction&Features

This large bottle servo automatic blow molding machine is its ability to produce large bottles of varying shapes and sizes, up to a maximum of 20liters. This is made possible through its unique pitch-changing structure, which allows preforms to be closely arranged during the heating process and then expanded when entering the blow mold. This design not only saves energy but also reduces the size of the machine and shortens the oven length.

Stable servo control

The blowing machine features precise and stable servo control for clamping, ensuring quiet and smooth operation.

Shorter Oven Made more efficiency

Its unique pitch-changing structure allows preforms to be closely arranged during heating and then expanded when entering the blow mold, resulting in a more compact machine with a shorter oven and greater energy efficiency.

Air recycle system save lost

An optional air recycle system further reduces compressor usage and energy consumption by recycling high-pressure air as a low-pressure air resource.

Easy to install and operate

The machine is easy to install and operate.

Our Equipment Usage

Product Details

  Name Description
Perform Feeding System Servo motors are used to separate the preform, effectively solving the problem of wear between the stuck and blown preforms.
Preform Transfer System The horizontal movement of the blown bottle system is driven by a servo motor, which can achieve twice the speed of the cylinder push mode, making it more precise and faster.
Mold Clamping System The reaction time can be shortened to 50% of the traditional pneumatic drive, with a simple structure, no wear, and an extended service life.
Constant Temperature Oven Our efficient constant temperature oven uses advanced infrared lamps, individually controlled layers, intelligent temperature control, self-rotation for even heating, and neck cooling with recycling water to prevent deformation.


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.
