Along with the increasing demand of the quality on packaging containers for food, pharmaceutical, cosmetic and high-grade daily necessities, the automatic injection & stretch blow molding technology is adapted to the needs of the market. By using this technology, the product is finished in one step from preform injection, forming by stretch & blow, to ejection. The production is of no flash, no deflashing material, avoiding double pollution, and the products have good quality on appearance, smooth mouth and excellent sealing. The technology has the advantages of realizing light weight on production process, with high speed, high efficiency, and energy saving etc..


Automatic injection blowing hollow molding machine - container solutions expert

Environmental protection

To reduce the work on operation, packaging, handling and storage, and cut down energy consumption, and with compact structure to occupy less space;
Cleanness
One step on product forming to avoid more pollution; 
Reliability
By using one step on forming to reach a minimum rate of defective products; 
Good forming
Precise positioning on bottle mouth, light weight on bottles, better parting line; adapting to abnormal shapes and high quality requirements on appearance.
 

Working principle

·Dual control system with synchronous action. Fast, stable and Precise.

·Four stations on the rotary table: injection, temperature adjusting, blowing and ejection. Four process is made on one machine, achieving one step injection and stretch blow molding.

·Servo vertical rotating mechanism, four separated station. Separated temperature adjusting, convenient for forming process adjusting.


Servo motor positioning system:

The rotary table mechanism adopts servo motor control system with high precision. Rotary table is sensitive and of accurate positioning.

Energy saving power system:

Adopts energy-saving variable pump or servo motor system and saves the electricity consumption up to 25%-50%.

Compressor air system:

Recycles the used high pressure air during bottle blow molding and reduces air consumption. (Optional)

Standard hot runner system:

No replacement of hot runner system when mold changing which reduces the mold cost.
