The history of China PET preform moulds is closely tied to the development of polyethylene terephthalate (PET) plastic and its growing use in packaging. PET, first synthesized in the 1940s, gained widespread popularity as a material for bottles and containers due to its strength, clarity, and recyclability. However, it was the invention and refinement of PET preform moulds that truly revolutionized the production of PET bottles.

In the 1970s, the first injection moulding technology for PET preforms emerged. Prior to this, glass and metal containers were the standard packaging options. PET preform moulds allowed for the mass production of PET containers in a highly efficient manner, making plastic bottles not only more cost-effective but also more lightweight than their glass counterparts. This innovation was crucial for the beverage industry, which sought a durable, transparent, and lightweight alternative for packaging drinks.

By the 1980s and 1990s, the development of multi-cavity moulds, automated systems, and precise temperature control systems significantly improved the speed and accuracy of preform production. These advancements enabled manufacturers to produce large volumes of preforms with minimal defects, making PET bottles more accessible for a variety of industries.

Today, PET preform moulds are an essential part of the packaging industry, continuously evolving to accommodate a range of shapes, sizes, and specialized designs. The ongoing improvements in technology ensure that PET preform moulds remain central to sustainable and cost-effective packaging solutions.
