  • PET Preform for Beverage Bottle OF The mold manufacturing process and product material selection
    The mold manufacturing and processing process of PET bottle preforms for beverage bottles includes steps such as mold design, mold manufacturing and mold debugging. 
    Mold design:
    Mold design is one of the key steps in manufacturing PET bottle preforms. During the design process, the following factors need to be considered:
    Shape and size of the preform: According to the shape and size of the preform, design the structure and cavity of the mold to ensure the accuracy and consistency of the preform.
    Bottleneck and thread design: According to the bottleneck and thread requirements of the bottle preform, design appropriate mold parts to ensure the quality and size of the bottleneck and threads.
    Cooling system design: Design a reasonable cooling system to improve cooling efficiency during the injection molding process and shorten the production cycle.
    Mold material selection: Choose appropriate mold materials, such as high-quality alloy steel or stainless steel, to ensure the hardness and wear resistance of the mold.
    Mold manufacturing:
    According to the mold design, the mold manufacturing process includes the following steps:
    Mold material procurement: According to the mold design requirements, select appropriate mold materials and proceed with material procurement.
    Mold processing: According to the mold design, CNC machining, EDM, wire cutting and other processes are performed to manufacture precision mold parts.
    Mold assembly: Assemble the mold parts to form a complete mold structure.
    Mold debugging: debug and optimize the mold to ensure the stability and production efficiency of the mold.
    Difficulties in mold manufacturing and mold cost advantages:
