How does a perfume spray pump work?

　　Perfume spray pumps say that liquid plastic is sprayed by a blow molding machine, and then the plastic body is attached to a certain shape of the mold cavity using the wind force blown by the machine to make the product. Plastic is melted and quantitatively extruded in a screw extruder, then molded with a perforated film, cooled with an air ring, and then hauled by a traction machine at a certain speed, and wound into a roll with a winding machine. Extrusion Blow Molding: Pellets (or powder) of thermoplastic are plasticized by an extruder, prepared into a hot melt tubular parison through a specific mold, and then blow molded. Injection blow molding uses separate molds to inject the parison into the mandrel. After the parison is properly cooled (the surface of the parison is cured so that the parison will not be damaged or vertically deformed when the mandrel is moved), the mandrel and parison are fed into the blow mold to close the blow mold. Compressed air is introduced through the mandrel to expand the parison to form the desired product. After cooling and shaping, the product is removed.

　　Perfume spray pump manufacturers say that stretch blow molding forces the parison to stretch over a specific temperature range. While molding, the macromolecules are arranged and fixed within the walls of the product, greatly improving the performance of the plastic container. A molding method in which a bottomed parison heated at an appropriate temperature below the melting point is placed in a mold and then stretched axially through a stretch rod and then immediately blow molded. Multi-layer blow molding is a molding method in which a multi-layer container is prepared by a blow molding process using a multi-layer composite blank. Through the reasonable matching of different plastic layers, the performance of each layer can be made to effectively complement each other, thus overcoming some of the 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 pumps is also constantly innovating, from the initial plastic cap, squeeze cap to the later spray pumps, each time for better storage of cosmetics, convenient for people to use. So what we mainly understand below is the advantages of perfume spray pump?

　　1. Excellent environmental protection, easy to recycle

　　2. Good sealing performance

　　3. The dose can be well controlled, which can bring great convenience in many fields, such as medical treatment. It is not suitable for applying on the wound or in the mouth, so the spray pump will come in handy.

　　In addition to the above advantages of perfume spray pumps, there are still some possible problems, such as accidental clogging and jamming during use, which will be more troublesome. However, in the future, perfume spray pump manufacturers will also make improvements.

　　Perfume spray pump has brought us a lot of convenience, more content you can contact our manufacturers.
