Machine Introduction&Features

Our blow molding machine is highly versatile and can produce various types of bottles, including water bottles, beverage bottles, and cosmetic bottles, making it an ideal choice for many applications. 

With our state-of-the-art technology, you can expect high-quality and consistent results every time.

Servo preform displacement system

Servo-controlled bottle preform displacement system.

Efficient servo system for automation

Rapid, accurate, stable, flexible, and energy-efficient servo system.

Hyperbolic arm linkage for high locking force

High locking force is achieved through the use of a hyperbolic arm linkage and a high-pressure locking mechanism.

High-precision stainless steel motion track

The motion track is made of high-precision stainless steel, with a precision of 0.1mm for smoother movement and lower noise.

Advanced high-frequency infrared lamp

The most advanced high-frequency ruby infrared lamp is used, which provides 30%-50% higher heating efficiency. Each layer of the lamp can be controlled independently.

Quick mold replacement design

The mold positioning drawer design allows for simple and quick mold replacement

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.
