Common problems and maintenance methods of hollow blow molding machine

Common faults and maintenance methods of hollow plastic blowing machine

In the process of production and processing of various plastic blowing products, the hollow blowing machine has the advantages of fast forming speed, stable product quality, high production efficiency, low energy consumption and low production cost. However, some common problems of the hollow blowing machine, we also need to understand, MEPER Machinery today to share with you is the hollow blowing machine common faults and maintenance methods.

Extrusion blow molding machine is not discharged or unstable

Hollow blowing molding machine does not feed or feeding instability is caused by many factors, for you to sort out the following common problems and methods. The starting temperature is low. Check whether the temperature of the extrusion cylinder and the head of the mold is required to meet the required processing standard. In the case of reaching the standard temperature, the heating time should be sufficient to make the internal and external temperature consistent.

Unstable extrusion barrel or die temperature

This requires checking the sensitivity of the temperature controller and adjusting it appropriately.

Glue sticks to the screw

Lower the temperature slightly before stopping the machine, and stop the machine only when there is no rubber at the screw feeding place, and clean the screw in time.

back pressure too low

Appropriately increase back pressure

filter clogged

Replace with a new filter

Product wall thickness distribution is uneven

Uneven wall thickness of blow molding products is a common problem of blow molding products, and it is also 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 or too long molding time will affect the wall thickness of blow molded products.

This needs to be achieved by using the corresponding hollow blow molding machine wall thickness control technology or wall thickness control equipment.

The mechanical arms of the hollow blow molding machine collide with each other

This will affect the normal work and production of the hollow blow molding machine, because a certain part is not installed correctly, and it must be reinstalled after inspection.

The hollow blow molding machine cannot be fed

Check whether the power supply is in the load state. The power supply is in the load state, which not only affects the feeding, but also makes the hollow blow molding machine unable to produce products normally.

The hollow blow molding machine is composed of multiple systems and parts. If one part fails, it 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 blow molded products, understand Common faults and maintenance methods of hollow blow molding machines are a very practical step.

As a manufacturer of hollow blow molding machines, MEPER Machinery mainly provides large-scale hollow blow molding machine equipment to support the processing and production of different plastic products. If you have hollow blow molding machine equipment or technical needs, you can consult in the consultation box next to it. . MEPER Machinery provides customers with reliable quality equipment and corresponding technical services, including installation and commissioning of hollow blow molding machines, technical training and after-sales service.

The unstable operation of the hollow blow molding machine, resulting in unstable operation of the equipment is also one of the common problems of the hollow blow molding machine.

Understanding the common faults and maintenance methods of the hollow blow molding machine is to enable us to better deal with the problems that occur during the use of the hollow blow molding machine. At the same time, before the hollow blow molding machine officially starts to operate and produce, we should carefully read the operating instructions and precautions equipped with the hollow blow molding machine, understand the characteristics and functions of each system and accessories, and understand the solutions to their common problems And precautions, so that we can pay more attention during the operation to avoid problems caused by misoperation, and at the same time learn to solve common problems.
