335ml PET Bottle Blow Mold
Material Integrity and Surface Protection
BJY insists on using high-quality imported solid extruded aluminum bars. Unlike lower-cost cast materials that may contain internal porosities or defects, our solid extruded bars provide superior fatigue resistance and excellent thermal conductivity. This is essential for maintaining the high-speed PET blowing cycles required for 335ml bottles. The Mold Shells undergo a specialized hard anodizing treatment. This process ensures the 150*408mm shell remains resistant to surface oxidation and the corrosive effects often found in high-humidity bottling plant environments where cleaning agents are frequently used.
Precision Inserts and Longevity
The neck and base areas of a 335ml PET bottle are critical for both sealing and structural stability. We utilize high-grade S136 stainless steel for these inserts, which are heat-treated and mirror-polished to a high standard. This prevents common issues like neck deformation and ensures the thread precision required for high-speed capping operations. By utilizing specific high-wear materials for these zones, we maximize the mold's overall lifespan and minimize the need for frequent part replacement.
•Premium solid aluminum for the highest possible heat transfer efficiency and structural strength during high-pressure blowing.
•Hard anodized shell finish to prevent surface wear and maintain precise dimensions over long production runs.
•Heat‑treated S136 stainless steel inserts for critical zones, ensuring zero dimension drift during millions of cycles of high‑speed operation.
•Mirror‑polished cavities to ensure the 335ml bottle achieves maximum transparency, clarity, and premium shelf appeal.
Choosing BJY means investing in a mold designed for longevity and consistency. We provide beverage plants with the material reliability needed to meet demanding production schedules without the constant risk of material‑related failure or quality drift in the 335ml bottle line.
