Product Overview
Designed for reliability and operational flexibility, our 8-cavity PET preform mould is the ideal solution for producers managing multi-SKU packaging lines or entry-level injection operations. With modular construction and precision-machined cooling circuits, this system ensures consistent preform quality and simplified maintenance.
Why Choose This 8-Cavity Platform?
Easier Process Optimization: Unlike 72+ cavity molds that require complex balancing, our 8-cavity platform is easier for operators to calibrate, ensuring stable weight (±0.2–0.4g) even with non-expert staff.
Thermal Symmetry: Multi-zone heating control maintains temperature variations within ≤ ±2°C, preventing gate whitening and black specks.
Modular "Easy-Swap" Design: All critical components (neck rings, core/cavity inserts, gate tips) are independently replaceable. This modularity allows your maintenance team to replace a damaged insert in under 30 minutes, without removing the entire mold from the injection machine.
Manufacturing & Quality Assurance
We provide transparency from raw material to delivery:
Steel Traceability: Every tool steel component is accompanied by a mill certification report.
FAT (Factory Acceptance Testing): Before shipping, every mold undergoes a 24-hour pressure test (10 Bar) on water circuits and a minimum 2-hour continuous production trial.
Data Transparency: You will receive a full Dimensional Inspection Report (CMM), FAT Video, and Trial Parameter Sheet to ensure the mold works in your facility from day one.

FAQ
Q: Why choose 8 cavities instead of higher cavity moulds?
A: An 8-cavity configuration offers easier process control, lower initial investment, and greater flexibility for frequent bottle format changes, making it perfect for multi-SKU product lines.
Q: Can one mould produce multiple neck finishes?
A: While the mold base and cavity pitch are fixed, you can switch neck finishes by replacing the neck ring and thread-forming inserts, provided the thread diameter remains within the platform design limits.
Q: Is valve gate necessary for 8 cavities?
A: Not always. Open gate is sufficient for standard bottles, while valve gate is recommended if you require a cleaner gate appearance (no nub) or are using high-viscosity resins that might cause stringing.
Q: What affects cycle time most in an 8-cavity setup?
A: The main factors are preform wall thickness, chilled water flow rate (8–15°C is recommended), PET drying quality, and the injection machine's cooling recovery capacity.
Q: What should be provided before quotation?
A: To receive an accurate quote, please provide your preform technical drawing, neck standard, target daily output, resin specs, and the technical parameters of your injection molding machine (clamping force, etc.).
Q: Does this mold require specialized maintenance equipment?
A: No. The modular design allows for standard hand-tool maintenance. We provide a maintenance manual and a complementary set of core wearing parts (heaters, thermocouples, seals) to get you started.
Q: How do you ensure the mold fits my existing injection machine?
A: Before manufacturing, we require your machine's platen layout, tie-bar spacing, and nozzle dimensions. Our engineers will customize the mounting plate and ring size to ensure a 100% "drop-in" fit.
Q: Can we run recycled PET (rPET) on this mould?
A: Yes. Our use of high-grade S136/1.2316 steel provides the corrosion resistance necessary to handle the volatile gases often released by rPET, maintaining high cavity finish over millions of cycles.
