1、 Functional composition

Blow molding machine: A blow molding machine is a plastic processing machine whose main function is to blow liquid plastic into a certain shaped mold cavity through the wind force blown out by the machine, thereby producing products. It usually includes components such as screw extruder, mouth film forming device, air ring blowing cooling device, traction machine, and winding machine. Blow molding machines can be divided into various types according to different needs, such as extrusion blow molding machines, injection blow molding machines, and special structure blow molding machines.

Blow molding unit: A blow molding unit is a production line composed of multiple devices, usually including blow molding machines, auxiliary machines (such as hopper dryers, mold temperature machines, etc.), conveying devices, and control systems. These devices work together to complete the entire process from raw material transportation, heating and plasticization, blow molding to product output. Blow molding units have a higher degree of automation and stronger production capacity, making them suitable for large-scale production.

2、 Application scope

Blow molding machine: Blow molding machines are mainly suitable for producing various hollow plastic products, such as bottles, containers, toys, etc. Due to its relatively simple structure and flexible operation, it is also suitable for small batch and multi variety production scenarios.

Blow molding unit: Blow molding units are more suitable for large-scale and continuous production scenarios, such as automotive parts, household appliance casings, large containers, etc. The blow molding unit has advantages in large-scale production by optimizing the production process, improving production efficiency, and reducing production costs.

3、 Production efficiency

Blow molding machine: Although blow molding machines can independently complete the blow molding process, their production efficiency is relatively low, especially when processing large or complex shaped plastic products. In addition, the operation and maintenance costs of blow molding machines are relatively high, requiring professional personnel to operate and maintain them.

Blow molding unit: Through the collaborative work of multiple devices, the blow molding unit can greatly improve production efficiency. Meanwhile, due to the optimized coordination between internal equipment of the unit, energy consumption and production costs can be reduced. In addition, blow molding units have a higher degree of automation and stronger production capacity, which can adapt to the production needs of products of different specifications and shapes.

In summary, there are significant differences between blow molding machines and blow molding units in terms of functional composition, application scope, and production efficiency. The choice of equipment depends on factors such as specific production needs, product specifications, and production scale.
