Understanding the Technique of PET Preform Mold Manufacturing

Behind every perfectly shaped PET bottle lies the precision of a PET Preform Mold the unsung hero of modern packaging. At LEO Precision, we take pride in mastering this art and science, combining engineering excellence with innovative design to produce world-class moulds trusted across the globe.

• 1. Design & Simulation: Every mould begins with precision CAD modeling and flow analysis, ensuring the ideal preform geometry for your bottle’s performance, weight, and clarity.
• 2. High-Grade Material Selection: We use premium tool steels and hardened alloys to ensure strength, longevity, and thermal stability.
• 3. Micro Machining & Polishing: Ultra-precision machining achieves cavity accuracy down to microns. Each cavity is hand-finished and polished for flawless surface quality.
• 4. Hot Runner Engineering: LEO’s advanced hot runner systems deliver balanced melt flow and uniform heating, eliminating flow lines and defects.
• 5. Testing & Validation: Every mould undergoes rigorous testing, including cycle time validation, part dimension checks, and performance trials before delivery.

Our moulds ensure high-output production with low maintenance, reduced downtime, and unmatched consistency. With compatibility across Husky, ASB, SIPA, and Nissei machines, LEO Precision stands as a global name in PET packaging technology.

At LEO Precision, every mould tells a story of innovation, craftsmanship, and commitment to profitability. We don’t just build molds. We build Profitable Packaging Solutions that power brands across the world.
