Common faults and maintenance methods of hollow blow molding machine

In the process of producing and processing various plastic blow molding products, the hollow blow molding machine has the advantages of fast molding speed, stable product quality, high production efficiency, low energy consumption and low production cost. However, we also need to understand some common problems of the hollow blow molding machine. What Yan Kang's editor wants to share with you today is the common faults and maintenance methods of the hollow blow molding machine.
The hollow blow molding machine does not discharge or the blanking is unstable
There are many reasons why the hollow blow molding machine does not discharge or the blanking is unstable. The editor has summarized the following common problems and methods for you.
Low startup temperature
Check whether the temperature of the extrusion barrel and die head meet the required processing standard. If the standard temperature is reached, the heating time should be sufficient to make the internal and external temperatures consistent.
Unstable temperature of extrusion barrel or die head
This requires checking the sensitivity of the temperature controller and adjusting it appropriately.
Glue stuck at screw
Lower the temperature slightly before shutdown, and stop the machine only when there is no glue at the screw feed, and clean the screw in time.
Back pressure is too low
Increase back pressure appropriately
Filter screen blocked
Replace with a new filter screen
Common faults and maintenance of hollow blow molding machine
Uneven distribution of product wall thickness
Uneven wall thickness of blow molded products is a common problem of blow molded products and one of the common problems of hollow blow molding machines.
Uneven wall thickness is generally related to temperature, cooling and processing time.
Improper temperature, uneven heating temperature, insufficient cooling, insufficient molding time or too long will affect the wall thickness of blow molded products.
This needs to be achieved by using the corresponding wall thickness control technology or wall thickness control equipment of the hollow blow molding machine.
The mechanical arms of the hollow blow molding machine collide with each other
This will affect the normal operation and production of the hollow blow molding machine, because a component is not installed correctly, and it should be reinstalled after inspection.
Common faults and maintenance of hollow blow molding machine
The hollow blow molding machine cannot feed
Check whether the power supply is in the load state. If the power supply is in the load state, it will not only affect the feeding, but also make the hollow blow molding machine unable to produce products normally.
The hollow blow molding machine is composed of multiple systems and components, and the failure of one part will affect the normal operation of the hollow blow molding machine. In order to ensure the normal production of the hollow blow molding machine and improve the quality of the blow molding products, it is a very practical step to understand the common failures and maintenance methods of the hollow blow molding machine.

Unstable operation of hollow blow molding machine
The unstable operation of the equipment is also one of the common problems of the hollow blow molding machine. There are many reasons for this. Yan Kang will not list them here. You can refer to another special introduction on the unstable operation of the hollow blow molding machine, which provides different solutions for different reasons.
