350ml PET Bottle Blow Mold
Overview
This 350ml PET bottle blow mold is made by Foshan Baijinyi Precise Technology Co., Ltd., a mold manufacturer based in Foshan, Guangdong.
It’s designed for Zhongyin rotary blow molding machines, commonly used on high-speed bottle production lines.
The mold body is built from 6061 aluminum alloy, treated through Baijinyi’s own process for better hardness and wear resistance.
It’s a practical choice for factories looking for stable bottle forming, easy maintenance, and consistent results during continuous runs.

How It Works
A PET preform is first heated until soft. It’s then placed inside the mold, and air pressure pushes it outward to form the bottle.
Once the mold closes, the cooling system starts working to help the bottle set quickly.
This gives a consistent 350ml shape and clear surface without deformation.
Applications
This mold is mainly used for bottles containing drinking water, juice, tea, milk drinks, and carbonated beverages.
Though this version fits Zhongyin machines, Baijinyi can also build compatible molds for other brands and production systems.
