Air-sealed preform mold plays an extremely critical role in the modern packaging industry. With its precise mechanical structure and advanced processing technology, it has created excellent performance and quality.
In terms of mechanical structure design, air-sealed preform mold shows a high degree of precision. Its core components such as cavity and core adopt high-precision CNC processing technology, which can control the dimensional tolerance at the micron level. For example, for the processing of the bottle mouth part of the preform, the precise thread structure design and manufacturing ensures high air tightness when it cooperates with the bottle cap. The mold structure is optimized by advanced means such as finite element analysis, so that the deformation of the mold is extremely small when it is subjected to high-pressure injection, ensuring the dimensional stability of the preform molding. At the same time, the parting surface of the mold is cleverly designed and closely fits, which effectively prevents the leakage of plastic melt during the molding process, laying a solid foundation for the production of high-quality preforms.
Advanced processing technology is a highlight of air-sealed preform mold. In the manufacturing process, multi-axis linkage machining centers are widely used, which can perform one-time precise machining of complex mold surfaces, reducing the cumulative errors caused by multiple clamping and processing procedures. For example, when processing molds with special-shaped preforms, multi-axis linkage machining can easily achieve smooth transition and precise molding of the curved surface. The surface treatment process of the mold is also extremely critical. The use of high-precision polishing technology and special coating treatment not only reduces the flow resistance of the plastic melt in the mold, improves the demolding performance, but also enhances the wear resistance and corrosion resistance of the mold, and extends the service life of the mold.
In addition, in the design of the cooling system of the mold, the cooling water flow channel is optimized with the help of advanced simulation software. By reasonably designing the diameter, spacing and direction of the cooling channel, the preform can be cooled evenly and quickly during the molding process, shortening the molding cycle and improving production efficiency. For example, the use of conformal cooling technology allows the cooling channel to fit the shape of the mold cavity, greatly improving the cooling efficiency and reducing the internal stress and deformation of the preform caused by uneven cooling.
Air-sealed preform mold, with its precise mechanical structure and advanced processing technology, achieves high-precision and high-quality molding of preforms. It plays an indispensable role in the packaging production of many industries such as beverages, food, and medicine, and has strongly promoted the development and progress of the packaging industry.
