Sample-Based Custom Design Service
In many projects, customers prefer to keep their existing bottle body design while upgrading or modifying the bottle base. This is often driven by market response, performance optimization, or packaging updates.
BJY supports sample-based customization:
Customers may send us a used bottom mold sample
We study the installation dimensions and structure based on the sample
A new bottom mold is designed according to the customer’s requirements
The original sample will be returned together with the newly produced mold
This process helps reduce development time and avoids compatibility risks on existing machines.
How It Works
During the blow molding process, the PET preform is heated and expanded inside the mold cavity. The bottom mold shapes the bottle base under controlled pressure, forming the final structure of the bottle bottom. A properly designed bottom mold contributes to balanced material distribution, good bottle stability, and consistent production quality.
