Bottle blowing is an important process in the packaging industry such as beer and beverages, and its purpose is to blow mold products into containers of a certain shape and specification. The blowing process usually includes the following steps:
1.Prepare materials: First of all, you need to prepare plastic preforms, caps, bottle bottoms and other materials.
2.Cleaning and sterilization: Preforms and caps are cleaned and sterilized to ensure that they are free of impurities and bacteria.
3.Heat treatment: The preform is heated to a certain temperature to make it soft and easy to blow mold.
4.Blow molding: The preform is placed into the blow molding machine, and the preform is blown into the desired shape and specification by compressed air.
5.Cooling and shaping: Cooling and shaping of the blow-molded container.
6.Inspection and packaging: inspect the blow-molded containers, and pack them after they are qualified.
During the blowing process, the following points need to be noted:
1.Control the temperature: the heating temperature of the preform should be moderate, too high will cause the preform to deform, too low will be difficult to blow molding.
2.Control the blowing pressure: the pressure of the compressed air should be moderate, too large will cause the preform to break, too small will be difficult to blow molding.
3.Control time: The time of blow molding should be moderate, too long will cause the preform to deform, too short will be difficult to blow molding.
4.Keep it clean: Keep it clean during the blowing process to avoid impurities and bacteria entering the bottle.
5.Avoid overheating: Avoid overheating during the heating process to avoid deformation of the preform.
6.Pay attention to safety: Pay attention to safety during operation to avoid being burned or injured.
The above are the basic steps and precautions of the blowing process, I hope it can help you. If you have any further questions or need further assistance, please do not hesitate to contact us.
