In the ever-evolving packaging industry, PET bottled beverages continue to dominate the market due to their lightweight, safety, and recyclability. The technological updates and quality assurance of core molds (blow molding and preform molding, etc.) in PET mold production lines are crucial to the efficiency and future of the entire industry. Foshan Baijinyi, as a professional manufacturing partner deeply rooted in the PET mold field, is willing to work with you to understand the pulse of the industry and seize development opportunities.
I. Steady Market Growth, Sustainable Development as the Core Engine
The global PET mold market is demonstrating strong vitality and a clear growth trajectory. According to industry research data, as of 2024, the global PET mold market size had reached approximately RMB 38.08 billion, and is expected to continue expanding at a compound annual growth rate of 5.4%, potentially reaching nearly RMB 54.73 billion by 2031. This growth momentum stems not only from the fundamental global beverage consumption base but is also closely linked to the global wave of green and sustainable development.
Currently, brand owners and manufacturers are actively promoting lightweight packaging and the application of recycled plastics (rPET). This is not a simple material replacement, but rather a revolutionary challenge to mold technology. When using reclaimed PET (rPET), its thermal variability is higher than that of virgin PET, posing challenges to traditional process adjustment methods and potentially leading to unstable bottle performance or reduced production efficiency. Therefore, high-precision molds capable of accurately adapting to the characteristics of recycled materials and ensuring the stability of preform and finished product quality have become an urgent need for industry chain upgrading. Currently, leading beverage companies such as Sprite and Nongfu Spring have set precedents by reducing the color of PET bottles to facilitate recycling.
II. Technical Standards First, Lightweighting and Intelligentization Go Hand in Hand
Facing new market demands, the industry is leading its development direction through technological innovation and standard setting.
Regarding the standardization of lightweighting technology: On March 1, 2025, the Chinese national recommended standard "General Technical Requirements for Lightweight PET Bottle Blow Molding Molds" (GB/T 44359-2024) officially came into effect. This standard, jointly drafted by leading enterprises and research institutions across the industry chain, provides unified specifications for the design, manufacturing, and inspection of lightweight PET bottle blow molding molds. This marks a new stage in lightweighting, moving from a spontaneous enterprise initiative to industry-wide collaborative advancement, aiming to systematically reduce raw material consumption and logistics costs.
In terms of intelligent and data-driven approaches: Industry leaders have begun to integrate virtual engineering and data science to address complex challenges. For example, laboratory-grade blow molding and thermal imaging systems can obtain precise tensile properties of materials and complete thermal profiles of preforms before production. This data-driven approach can reduce process debugging time by an average of 30%, significantly reducing the risks and costs in new bottle development and material conversion.
III. Innovation Drives the Future: From Mold Manufacturer to Solution Partner
Industry trends indicate that future competition will not only be about mold hardware, but also about the ability to deeply understand materials science and process data, and provide end-to-end solutions.
