The hollow blow molding process is a plastic processing method, which can also be said to be a processing method of hollow plastic products. So, how does hollow blow molding process plastics? What can it do with the plastic processing method it has?
The principle of hollow blow molding
The molten raw material is extruded or injected to form a plastic tubular parison, which enters into a mold with a specific shape. By blowing a certain volume of compressed air, the parison in the mold is inflated. After the interior of the parison is filled with air, It will expand, so that the parison gradually adheres to the mold, and the molding of the product is initially completed.
This process, to use the technical term, causes the polymer to deform rapidly near the vitrification temperature and thus remain in this state.
The next step is cooling, so that the formed product is demolded and taken out. The cooling step is to cool the product to below the glass transition temperature or crystallization temperature in a relatively short period of time after the product is formed, which can also be said to be frozen and formed. product.
The above is the principle of hollow blow molding process, which can also be said to be the production process of hollow blow molding. The editor uses specialized terms and vernacular methods to introduce cross-introduction to facilitate everyone's better understanding. If you see these terms that are almost incomprehensible in other places, you can know what they mean.
So what can we achieve by using the principle of hollow blow molding?
The plasticity of the hollow blow molding process is still very large, and the development prospect is also very good. There are many things that can be done. for example:
First of all, let's talk about the plastic water bottles, plastic cosmetic containers, medicine bottles, beverage bottles, children's toys, baby bottles, etc. that we often see in our lives.
The hollow blow molding process was first used in the production of industrial plastic products, such as industrial barrels, chemical barrels of various calibers, and plastic turnover trays that can be used in our logistics and transportation industry.
In addition to the above frequently seen, there are also roadblocks, water horses, anti-collision buckets, enclosures, mobile toilets, septic tanks, plastic desktops, plastic bed boards, etc., which can be produced by hollow blow molding.
Products produced by hollow blow molding
Just now, the editor mentioned to you that the plasticity of the hollow blow molding process is very strong. In addition to the products listed above, the hollow blow molding process can be adjusted according to the needs of the product, and the production process can be customized, but we need to make reasonable use of the principle of hollow blow molding to better realize its The value lies in producing the products we need.
