Randomised words which don’t look even slightly Leizhen specializes in designing and manufacturing high-cavitation molds (including 48-cavity, 72-cavity, and even 144-cavity systems) that meet the demands of mass production. Their molds are engineered to ensure:

Uniform Preform Quality: Advanced flow simulation software balances the runner system, guaranteeing consistent filling and wall thickness across all cavities.

Tight Tolerances: Precision machining (±0.005mm) ensures compliance with international standards (e.g., PCO 1881, BPF) for neck finishes and thread designs.

Durability: Molds are crafted from premium steel (H13, S136, or 420 stainless steel) with heat treatment (HRC 48–52) to withstand millions of cycles.

Leizhen integrates state-of-the-art technologies to enhance mold performance:

Conformal Cooling Channels: 3D-printed or machined cooling channels follow the contour of the preform, reducing cycle times by up to 30% and minimizing warpage.

Hot Runner Systems: Partnerships with top brands like Yudo or INCOE ensure leak-free, energy-efficient melt delivery. Valve-gated systems enable clean gate cuts for lightweight preforms.

High-Speed Compatibility: Molds are optimized for machines with clamping forces up to 1,500 tons, achieving cycle times as low as 8–12 seconds for 20g preforms.

Leizhen tailors molds to meet specific client needs, including:

In-House Testing: Every mold undergoes trial runs on injection molding machines to validate cycle times, cooling efficiency, and preform dimensions.

ISO Certification: Compliance with ISO 9001 standards ensures traceability and accountability at every production stage.

Third-Party Inspections: Collaborations with global certification bodies verify compliance with FDA, EU, and other regional regulations for food-grade PET.

Leizhen’s commitment to quality is reflected in its stringent QC processes:

While European and North American manufacturers often come with premium price tags, Leizhen strikes a balance between affordability and performance:

Competitive Pricing: Direct manufacturing in China reduces overhead costs, offering savings of 20–40% compared to Western suppliers.

Long Mold Lifespan: Durable materials and coatings (e.g., nitriding, DLC) extend mold life to 3+ million shots, lowering cost-per-preform.
