Oil Bottle PET Preform Mold

The dimensional accuracy of the oil bottle preform directly affects. The subsequent blowing process and the quality and performance of the final oil bottle. When designing molds, it is necessary to accurately plan the length, diameter, wall thickness and other dimensions of the bottle embryo to ensure that the bottle embryo can meet the capacity requirements for edible oil after being blow-molded into an oil bottle, and to accurately cooperate with supporting components such as bottle caps and bottle patches. Bottle Thread The design of the bottle mouth thread of the oil bottle is crucial.

It needs to design a matching high-precision thread structure according to different bottle cap types and specifications. The tooth type, pitch, rotation direction and other parameters of the thread must be accurate to ensure the close cooperation between the bottle cap and the bottle preform and prevent the leakage of cooking oil. Mold Steel: P20 steel H13 steel high-quality mold steel, It has good strength, hardness, wear resistance and corrosion resistance, can withstand high pressure, high temperature and friction during injection molding, ensure the service life and molding quality of the oil bottle PET preform mold, and is often used to manufacture key components such as cavity and core. Some mold parts can be made of alloy materials such as aluminum alloy, which have the characteristics of low density and good thermal conductivity, which can reduce the weight of the mold and improve the opening and closing speed of the mold.

At the same time, good thermal conductivity will help the rapid cooling of the bottle preform and shorten the molding cycle. Using CNC machine tools for milling, drilling, boring, grinding and other processing operations, it can accurately manufacture various parts of the mold, ensure the dimensional accuracy and surface quality of the parts, and meet the high precision requirements of mold design.
