How is the plastic bottle made? The health care product plastic bottle manufacturer will introduce to you below:
There are two main manufacturing methods for plastic packaging bottles: extrusion blow molding and injection blow molding. The main injection molding process for plastic packaging bottles is that in the process of injection molding, the main mold of the plastic bottle used for molding comprises a female mold and a male mold. Use the injection molding machine to inject the plastic melt into the cavity of the mold under the high pressure. When opening the cavity, be sure to remove the male mold from the inside of the female mold and push the bottle out. The following mainly introduces the characteristics of injection molding of plastic packaging bottles.
The melt of the plastic bottle is injected into the parison mold and is subjected to a corresponding orientation effect around the inside of the cavity. In addition, the ambient temperature of the parison blow molding is lower than that of the extrusion blow molding, and the orientation effect generated during the blow molding process can be retained a lot. This phenomenon can improve the overall strength of the plastic packaging bottle and the like. performance.
The size and accuracy of the plastic packaging bottle are high and accurate, and it is relatively easy to ensure the thickness of the plastic bottle wall is uniform and the specifications are the same according to the manufacturing requirements. The surface of the plastic packaging bottle does not form a joint seam, and it does not need to be trimmed after molding. Under normal circumstances, no residual material of the corners is generated, and the scrap material produced by extrusion blow molding is generally 5-30%. The plastic packaging bottle The degree of gloss is relatively high, and the use of transparent polymers to produce molded plastic bottles is more transparent.
The sliding bottom module can be designed on the blow mold of the plastic bottle, so the flexible design of the bottom shape of the plastic package is relatively large. It is more suitable for the manufacture of molded plastic bottles and wide-mouth plastic bottles. In general, most of the plastic bottles used for injection blow molding are relatively small plastic bottles. For products with very complicated shapes, the energy consumption rate will increase significantly.
