General maintenance and repair rules for blow molding machines

Introduction of two methods of blow molding processing: extrusion blowing and injection blowing? Blow molding processing is divided into extrusion blowing and injection blowing.

(1)Extrusion blowing refers to the ordinary blow molding process (ie: the raw material is plasticized and then the parison is extruded and then blown)

(2)Injection blowing is the process of blow molding the embryo tube and then blow molding, injection blowing is also called pull blowing, and pull blowing is divided into one-step and two-step methods.

l One-step stretch blowing is completed by injection molding and stretch blowing by one machine. First, the parison is injected (the parison mold must be produced with mold temperature) to ensure that the temperature sufficient for blowing and expansion enters the stretch blow mold cavity for stretch blowing.

l The two-step rule is that the injection molding machine injects the parison first and then heats it again for stretch blowing.

Blow molding machine is a kind of equipment that makes plastic pellets into hollow containers by blow molding process. The more common models include hollow extrusion blowers that use PP and PE for one-time molding. Plastic hollow containers are not only light and cheap, but also have high safety features. They can be seen everywhere in our lives, especially all kinds of beverage bottles used at home are made of plastic as raw materials. Then we must know how to maintain the machine in the process of frequent use of the blow molding machine.

I Routine maintenance

1. Before using the blow molding machine, you should carefully check whether the moving parts are firm, and you need to carefully check whether the screws are loose. If there is, it should be tightened in time for safety and stability during use.

2. For places with very strong impact force, it is necessary to check whether the belt drive part is normal, whether there is serious wear and tear, which needs to be replaced and processed, and it is also necessary to add lubricating oil to each part to ensure that the service life of the equipment is longer.


II Maintenance rules that must be implemented for blow molding machines

Repairing the blow molding machine in a certain order can not only ensure the normal production of the product, but also prolong the service time of the machine and equipment. Therefore, in the maintenance of the blow molding machine, the following maintenance rules must be correctly implemented to improve product quality and productivity.


When the blow molding machine fails, it must be repaired as soon as possible. If it can be repaired during power outage or product replacement operation, it will help to reduce downtime and not delay machine production.


For the parts that affect the blowing quality of the blow molding machine, it needs to be replaced or repaired every six months. If there are parts that do not affect the quality of blowing, they can be used for a longer time, which can reduce maintenance costs.


If you want to repair a large area of the blow molding machine, it is best to repair it at the time of the maintenance of the glass melting furnace to avoid the shutdown of the blow molding machine during the production process.
