The cooling water of the hollow blow molding machine, its function can be seen from its name, that is, cooling, but, in different process links of the hollow blow molding machine, the role of cooling is different, let's take a look What is the use of the cooling water of the hollow blow molding machine, and what are the different functions.

The role of the cooling water in the blow molding machine mainly has two aspects: on the one hand, it is the role of the product, and on the other hand, it is the role of the equipment of the hollow blow molding machine.

First let's talk about the effect of the cooling water of the hollow blow molding machine on the product


Accelerated cavity cooling

The cooling water accelerates the cooling of the mold cavity. After the product is formed, the cooling water enters the mold cavity to better separate the product from the mold cavity and complete the demoulding after molding;

Speed up product forming

After the parison enters the mold and is initially formed, cooling water is required for cooling, so as to form faster. In addition to speeding up the forming, the cooling water of the hollow blow molding machine also ensures the geometric shape and internal structure of the product. ;

Of course, not all products are cooled with the same cooling water. We also need to consider the material of the product. If it is an amorphous product, it can be directly cooled with cooling water. If it is a crystalline product, it can be directly cooled with cooling water, which will not ensure the quality of the product, but will cause quality problems. 

Next, it's time to talk about the effect of the cooling water of the hollow blow molding machine on the equipment itself.

Reduce the temperature of equipment components

In the production process of the hollow blow molding machine, the operation of the machine and the production needs will make the temperature of some parts too high. The function of the cooling water in this case is to reduce the temperature of these parts, so as to prevent the equipment from overheating and causing failure;

Cooling screw

When the screw is working, a large amount of heat will be generated due to high-speed rotation and stirring. The role of cooling water here is to eliminate the friction and overheating phenomenon of the screw, thereby stabilizing the plasticizing ability of the screw, but the cooling process of the screw needs to be gradual. Cooling will cause equipment production accidents;

What is the use of cooling water for hollow blow molding machines? Yankang hollow blow molding machine manufacturers introduce the role of cooling water in the production process of hollow blow molding machines from two aspects: products and equipment. Its role cannot be underestimated. However, it must be used reasonably to make better use of it. We need to use the cooling water of the hollow blow molding machine reasonably according to the needs of different processes.
