Hot Runner Preform Mold with 24cavity

 

Hot Runner Preform Mold With 24 Cavity is commonly used in high-speed PET injection molding systems where cavity balance and thermal stability are critical factors affecting preform weight consistency and downstream blow molding performance.

 

Developed for stable multi-cavity operation, consistent cavity balance, and long-term production reliability, this mold integrates seamlessly into high-speed injection molding environments.

 

This mold design follows common engineering principles used in high-speed PET preform tooling systems widely adopted in beverage packaging production lines globally.

Integrated Beryllium Copper inserts and independent spiral cooling channels achieve an efficient 11-to-14-second cycle time.

 

Hardened Swedish ASSAB steel components machined within ±0.005mm allow direct replacement without manual fitting.

 

A pneumatic valve-gated hot runner system with independent cavity temperature control prevents gate leakage and stringing.

 

High-precision Makino CNC and Sodick EDM machining keep preform eccentricity at ≤ 0.08mm to ensure blow molding stability.

 

 

 

Our machining and validation process aligns with typical industrial mold manufacturing workflows used in export-oriented PET tooling suppliers serving global beverage packaging manufacturers.

Precision Machining: All mold inserts are processed using in-house Makino CNC and Sodick EDM machines to guarantee strict dimensional control and concentricity.

 

Pre-Shipment Testing: Every 24-cavity mold undergoes a mandatory 4-hour dry run test and a 500-shot trial production on our dedicated PET injection molding machines.

 

Traceable Compliance: Certified under ISO 9001:2015. Full steel certificates, heat treatment reports, and trial videos are supplied with every shipment.

 

 

Optimized for standard PET-specific injection molding machines (e.g., Husky, KraussMaffei, Netstal, Haitien, or equivalent models). We custom-tailor the mold plate dimensions and ejector layouts to match your specific machine specifications.

 

These machine platforms represent mainstream global PET injection molding systems commonly used in industrial-scale beverage packaging production.

 

 

To ensure the 24-cavity mold arrives at your facility in pristine, production-ready condition, we implement a strict export packaging protocol:

Anti-Rust Treatment: Application of high-grade, long-lasting anti-rust oil on all core, cavity, and mold base surfaces.

 

Vacuum Sealing: Complete wrapping with thick anti-static vacuum sealed plastic film and desiccant packs to repel moisture during maritime transit.

 

Reinforced Wooden Crating: Secured within an international standard, fumigation-free heavy-duty wooden box equipped with internal bracing to prevent shift or impact damage.

 

 

To ensure uninterrupted production, every mold ships with a complimentary spare parts package, including: Core/Cavity rubbing blocks, Neck screw components, Heating bands, Thermocouples, Valve pins, and high-temperature O-rings.
