Working Principle of IBC Container Blow Molding Machine

1. Raw Material Preparation: Firstly, the raw material (usually polyethylene or other plastic pellets) is fed into the machine's hopper. Before entering the main production area, it usually undergoes some pre-treatment steps such as drying and heating to ensure the raw material has the appropriate temperature and humidity.

   
   

2. Mold Assembly: An IBC container blow molding machine includes a mold, the shape and size of which determine the final shape and size of the produced container. The mold typically consists of two or more parts that can close and separate for injecting the raw material and extracting the finished product.

   
   

3. Injection Molding: The raw material is injected into the mold. The injected material is heated by the heating system, softening it and making it pliable. Once the mold cavity is filled with material, the heating system stops heating.

   
   

4. Blow Molding: Once the mold cavity is filled with material, air is injected into the mold to force the material to conform to the mold surface. This process is called blow molding, as it resembles the process of blowing plastic into mold shapes with airflow. The pressure and temperature applied to the mold control the thickness and shape of the final product.

   
   

5. Cooling and Solidification: Once the plastic has taken the shape of the mold, the mold is cooled. Cooling is typically achieved through an integrated cooling system, which can be a water circulation system or other cooling media. Cooling and solidification ensure that the molded plastic retains its shape and is solid enough to be ejected from the mold.

   
   

6. Extraction of Finished Product: After cooling, the mold opens, and the finished product is extracted. Mechanical arms or other automated systems are often used to execute this step to ensure that the produced containers are not damaged.

Through these steps, an IBC container blow molding machine can efficiently produce containers that meet the required specifications, satisfying customer demands.
