Thermal Management and Cooling Design

The cooling phase is the most time-consuming part of the PET blow molding cycle. BJY applies decades of engineering experience to design cooling water circuits that follow the 335ml cavity profile precisely. By maintaining a uniform temperature across the 150*408mm mold body, we eliminate thermal inconsistencies that can lead to bottle deformation and scrap. This thermal precision allows beverage plants to maintain stable production at higher speeds, directly increasing the daily output and efficiency of the 335ml line. Our water circuits are designed to maximize heat exchange efficiency.

Mechanical Compatibility and Stability

Reliable production requires a perfect fit between the mold and the machinery’s rotary system. Our 150*408mm molds are machined to strict specifications to ensure full compatibility with the Bestcrown mold mounting system. This precision reduces the need for manual adjustments during installation and ensures the mold remains stable under the continuous high-speed movement of the rotary machine. Proper alignment is key to reducing wear on the equipment’s cam system and maintaining the structural integrity of the bottle.

• Optimized cooling water channel layout to facilitate faster heat removal and more stable cycle times across all production shifts.

• Precise 150*408mm dimensions ensuring a stable and secure fit within the Bestcrown mold carrier to prevent vibration.

• Advanced cavity finishing to improve bottle release and reduce scuffing during the stripping phase for better yield.

• High-precision alignment features to maintain consistent bottle quality and wall thickness across all cavities.

Technical teams at beverage plants value BJY because our products are built for the reality of the production floor. We understand that a mold must perform consistently 24/7. Our goal is to ensure your 335ml production line remains one of the most reliable and efficient operations in your facility, maximizing your machinery investment.
