The shape, size, and quality of the bottle face are all determined by the water bottle preform mold, a crucial element in the plastic bottle manufacturing process. Using high-quality mold steel will ensure the mold's service life and the bottle's molding quality since it has strong strength, hardness, wear resistance, and corrosion resistance. It can also tolerate high pressure, high temperature, and friction during injection molding. A wide variety of bottle molds are available. It can be separated into single cavity molds and multi-cavity molds based on the number of cavities. Multi-cavity molds can lower costs and increase manufacturing efficiency.

• Mold Cavity Creation: Designing a mold cavity, which symbolizes the intended shape of the PET preform, is the first step in the process. Usually, premium steel is used to create these cavities in order to endure the strain and high temperatures involved in the injection molding process.
• Injection of Plastic Resin: Tiny PET resin pellets are loaded into the hopper of the injection molding machine. A molten plastic substance is created by heating and melting the pellets.
• Injection into the Mold: Next, under intense pressure, the molten plastic is pumped into the mold cavity. This guarantees that the material fills all of the cavities and forms a precise, consistent preform shape.
• Cooling and Solidification: The molten plastic mold is left to cool and solidify following injection. To get the best outcomes, cooling time is carefully regulated.
• Ejection: The preform is forced out of the cavity by ejector pins when the mold is opened after it has set.
