Zero-Failure Mold Testing: 100% Quality Assurance for Preform Molds

Why Our Preform Molds Stand Out

Our molds are meticulously designed, machined, and tested to eliminate defects and maximize efficiency. Key advantages include:

✅ Zero Defect Guarantee – Every mold undergoes rigorous testing before delivery, ensuring 100% molding rate with no rejects.
✅ Ultra-Durable Construction – Made from premium hardened steel with advanced heat treatment for extended service life.
✅ Optimized Cooling & Cycle Time – Precision-engineered cooling channels enable faster production without compromising quality.
✅ Customization Ready – Tailored to your specific preform design (neck finish, weight, wall thickness) for seamless integration into your production line.

Our Strict Mold Testing Process

Before any mold leaves our facility, it must pass three critical validation stages:

1. Trial Production Run – We mold sample preforms to verify dimensional accuracy and material distribution.

2. Performance Stress Test – The mold undergoes high-cycle testing to ensure stability under continuous operation.

3. Final Quality Inspection – Each preform is checked for:

   • Weight consistency

   • Wall thickness uniformity

   • Neck finish perfection

Only after 100% compliance do we approve the mold for delivery.

The LEIZHEN Advantage

• Reduced Downtime – Our molds are built for longevity and easy maintenance, minimizing production interruptions.

• Energy Efficiency – Optimized cooling systems lower energy consumption, cutting operational costs.

• Global Reliability – Trusted by PET manufacturers worldwide for consistent, high-output performance.

Conclusion

When you choose LEIZHEN preform molds, you’re not just buying a tool—you’re investing in unmatched precision, reliability, and efficiency.
