BJY Molds 570ml Aseptic Production

In high-speed liquid packaging, the gap between a successful run and a pile of waste usually comes down to the small details of the blow mold. At BJY, we’ve spent over 20 years getting the PET blowing process just right. Our 570ml aluminum blow molds are built to work seamlessly with Sidel machinery and represent the best of our engineering skills.

Tackling the Aseptic Challenge
Aseptic lines need a specific set of mold features. The gear has to keep a sterile environment while running at full mechanical speed. BJY handles this with a hygiene-first design. We get rid of the tiny cracks where bacteria could hide and make sure all surfaces stand up to standard industrial cleaning. Our 570ml molds have optimized water lines for fast, steady cooling—a big factor in keeping bottles clear and strong throughout the aseptic chain.
The Edge of Extruded Aluminum
We stick to imported, extruded aluminum bars for a reason. It comes down to toughness and performance. Extruded aluminum gives a more predictable thermal response than old-school cast materials. This gives you tighter control over the blowing process, so every 570ml bottle meets your high standards. Since the material is lightweight, it also puts less stress on your Sidel station's mechanical arms, helping your expensive equipment last longer.
