PET Blow Mould Design
After you confirm the bottle drawing or 3D sample, we start make mold design based on your stretch blow molding machine parameters.
Blow Mould Manufacturing
Next, we take the drawing to start mold manufacturing.
It usually takes 10 – 30 days to get the mold done.
We will do the mold trial twice on our machine at least, and will send you final samples for final confirmation.
