Production process and process of laundry detergent bottle

Laundry liquid bottles have certain production processes and methods during production, and the processing methods of laundry liquid bottles include: extrusion blowing, injection molding, calendering, blow molding, molding, lamination, casting, and many other methods.

There are two commonly used production processes for laundry detergent bottle manufacturers:

The first is the extrusion blowing process, that is, the plastic raw material is added to the extruder, the molten parison is extruded by heating, melting and plasticizing, and then put into the bottle mold for inflation molding. After cooling and setting, it is taken out from the mold and trimmed. After the finished product is obtained. This process is mainly used to produce polyethylene and polyvinyl chloride laundry detergent bottles, such as milk bottles, soy sauce bottles, etc.

The second is the injection stretch blow process, that is, the plastic raw material is injected into a tubular parison by an injection molding machine, and then put into a bottle mold for stretch blow molding, and the finished product is obtained after cooling.

Laundry liquid bottle is passed after blow molding, plastic is heated and melted, and then pressed into a special blow molding mold and internal air pressure, pressure, mold plastic to form the shape of the final product, because the shape of the bottle is outward pressure time, Therefore, it is emphasized that when the bottle itself is inward, the heating temperature reaches a certain level, which will soften the plastic, and the resistance of the pressure will become smaller, so the bottle will become smaller and smaller.

During production and processing, the laundry detergent bottle manufacturer will process according to a certain grace period treatment method to ensure the quality of production and processing and the amount of use with good performance.
