How about perfume spray pump

The perfume spray pump said that after the liquid plastic is sprayed out by the blow molding machine, the plastic body is attached to the mold cavity of a certain shape by the wind force blown out by the machine, so as to make the product. The plastic is melted in the screw extruder and extruded quantitatively, then formed with the orifice film, cooled with the air ring, then pulled by the tractor at a certain speed, and wound into a reel by the winding machine. Extrusion blow molding: thermoplastic particles (or powder) are plasticized by an extruder, and then prepared into a hot melt tubular parison through a specific mold, and then blown into shape. Injection blow molding uses a parting die to inject the parison into the spindle. After the parison is properly cooled (the parison surface is solidified, and the parison will not be damaged or vertically deformed when moving the core mold), send the core mold and parison to the closed blow mold of the blow mold. Compressed air is introduced through the spindle to expand the parison to form the desired product. After cooling and shaping, take out the product.
The manufacturer of perfume spray pump said that stretch blowing forced the parison to stretch within a specific temperature range. At the same time of molding, macromolecules are arranged and fixed in the wall of the work in progress, which greatly improves the performance of the plastic container. A forming method in which a bottomed parison heated at an appropriate temperature below the melting point is placed in a mold, then axially stretched through a stretching rod, and then immediately blown into shape. Multilayer blow molding is a molding method for preparing multilayer containers by blow molding process using multilayer composite billets. Through the reasonable collocation of different plastic layers, the performance of each layer of plastic can be effectively complementary, thus overcoming some inherent shortcomings of single-layer plastic containers. It should be noted that the two plate injection molding machine should keep enough plastic raw materials. And different raw materials should be dried to different degrees according to the requirements, which can also meet our processing requirements. Generally speaking, the personnel who operate the equipment need to be trained. If you are a novice, try to be guided by the staff.
The design of perfume spray pump is also constantly innovating. From the initial plastic cover, extrusion cover to the spray pump, each time is to better store cosmetics and facilitate people's use. So what we mainly know below is the advantages of perfume spray pump?
1. Excellent environmental protection, easy to recycle
2. Good sealing performance
3. The dosage can be well controlled, which can bring great convenience in many fields, such as medical treatment. It is not suitable for application on wounds or in the mouth, so spray pump will be useful.
In addition to the above advantages, the perfume spray pump also has some problems that may occur. For example, it will be troublesome if it is accidentally blocked or jammed during use. However, in the future, perfume spray pump manufacturers will also make improvements.
