16 Cavity PET Preform Mold - Hot Runner, S136 Steel High-Efficiency Hot Runner Preform Tooling System
LEIZHEN MOULD is a specialized manufacturer dedicated to the design and production of high-precision PET preform moulds. Our 16 Cavity PET Preform Mould is engineered for efficiency, durability, and consistent output quality — ideal for producing preforms used in water, beverage, edible oil, and other packaging applications.
This mould features a hot runner system, balanced cavity filling, and precision cooling channels to ensure short cycle times and long mould life. Each cavity is machined with advanced CNC equipment and polished to mirror finish, guaranteeing preforms with excellent clarity and dimensional accuracy.
LEIZHEN MOULD is a professional manufacturer specializing exclusively in PET preform moulds and injection tooling solutions. With years of focused experience in the preform industry, we provide reliable, high-performance moulds for producing preforms used in water bottles, beverage containers, edible oil packaging, carbonated soft drinks (CSD), and more.
Our 16 Cavity PET Preform Mould is engineered for medium-scale production lines, offering an ideal balance between output capacity and operational economy. Below are the key features and technical advantages of this mould system:
1. Precision Machined Cavities
Each of the 16 cavities is machined using high-precision CNC equipment and finished with mirror polishing. This ensures that every preform has excellent neck finish accuracy, consistent wall thickness, and superior transparency — essential for high-quality bottle blowing.
2. Optimized Hot Runner System
The mould is equipped with a balanced hot runner manifold that ensures uniform melt flow to all 16 cavities. This design minimizes pressure loss, reduces material degradation, and enables faster injection cycles while maintaining preform weight consistency across all cavities.
3. Efficient Cooling System
Our 16-cavity preform mould features an advanced cooling circuit design with strategically placed channels around the neck, body, and gate areas. This significantly reduces cooling time, leading to shorter overall cycle times (typically between 8–12 seconds depending on preform weight) and higher daily output.
4. Durable Material & Long Service Life
All mould plates are manufactured from high-grade stainless steel or pre-hardened steel (depending on customer preference). The core and cavity components are made from corrosion-resistant materials, suitable for high-volume production of several million cycles with minimal maintenance.
5. Interchangeable & Modular Design
The mould is designed with flexibility in mind. Neck rings, core pins, and cavity inserts are interchangeable, allowing you to switch between different preform neck finishes (e.g., PCO 1881, 30/25, 38 mm, etc.) without replacing the entire mould.
6. Easy Maintenance & Fast Delivery
As a dedicated PET preform mould manufacturer, LEIZHEN MOULD provides full technical drawings, spare parts lists, and maintenance guidelines with every mould. We also offer quick turnaround on spare parts and repair services.

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.
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.
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.
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.
