Product Description
Optimize your packaging production with our precision-engineered PET Preform Hot Runner Moulds. Built for continuous high-output operations, this multi-cavity system delivers reliable preform weight control, stable neck finishes, and minimized material waste across 8 to 128 cavities.
Process Control & Verified Trustworthiness
Our factory establishes Trustworthiness through absolute process transparency and 100% traceably recorded internal engineering protocols.
In-House Manufacturing Traceability
Original Material Certification: Every block of S136 or 1.2316 steel used for cavities and cores is delivered with original mill sheets and hardness testing logs to ensure zero counterfeit steel.
Standard Processing Chain: All components follow a strict internal routing: CNC Machining → EDM Processing → Vacuum Heat Treatment → Precision Grinding → Mirror Polishing → Coordinate Measuring Machine (CMM) Dimensional Inspection.
Strict Factory Acceptance Testing (FAT) Protocol
Before any mold is packed and shipped, it must pass our Mandatory 4-Step Verification:
Pressure & Leak Testing: The entire cooling circuit undergoes continuous 24-hour water pressure testing at 10 Bar to ensure zero internal leakage.
Thermal Distribution Logging: Hot runner manifolds are dry-tested to verify that temperature variation between all cavities remains strictly within ≤ ±2°C.
Continuous Trial Run: A minimum 2-hour continuous trial injection run is performed on our in-house testing machines to log structural stability and cycle times.
Cavity Balance Sampling: Samples from all cavities are physically measured and weighed to confirm uniform filling and structural balance.
Transparency Documentation Pack Delivered with the Mold: Full CMM Dimensional Inspection Report, 2D/3D Mechanical Assembly Drawings (STEP/DWG format), Trial Production Parameter Sheet & FAT Testing Video.
Engineering Details: Resolving Critical Packaging Deficiencies
Thermal Control & Melt Balance
Our hot runner manifolds feature equal-flow path distribution and multi-zone PID heating control. By eliminating localized overheating, the system effectively reduces gate whitening, black specks, and acetaldehyde (AA) resin degradation, improving preform transparency.
Independent High-Flow Cooling Structure
Dedicated independent cooling channels for each individual cavity and core insert ensure rapid thermal recovery.
Thermal isolation at the neck ring prevents heat from the hot runner drifting to the threads, keeping neck concentricity ≤0.03mm and parting line mismatch ≤0.02mm to prevent future cap leakage.
Operational Requirement: Optimal cycle time requires a chilled water input of 8–15°C.
Service-Oriented Modular Construction
We minimize your operational downtime through a completely modular mold architecture. Critical high-wear areas can be serviced or replaced directly on the injection machine without dropping the complete mold base
.
Fast-Replacement Parts: Gate tips, heaters, and thermocouples feature separate, modular plug-and-play mountings.
Independent Servicing: Cavity inserts, core inserts, and neck rings can be individually swapped out in the event of accidental damage, reducing your spare parts inventory costs.

FAQ
Q: Which data should buyers prepare before project discussion?
A: To provide an accurate quotation and compatibility check, please prepare your preform 2D/3D drawing, neck standard (e.g., PCO1881), bottle application, target hourly/daily output, resin technical specification, and your injection molding machine parameters.
Q: What brand of hot runner system and heating components do you use?
A: We configure balanced hot runner systems utilizing premium heating elements and high-sensitivity thermocouples. For components matching customized or global standards, we ensure fully standardized wiring layouts, making it highly convenient for your local maintenance teams to source drop-in replacements globally.
Q: How do you handle wearing parts and long-term spare parts availability?
A: Every mold is shipped with a standard set of critical wearing parts (including gate tips, heaters, thermocouples, and seals) free of charge. Additionally, we keep the original 3D manufacturing records of your specific mold platform in our database for over 10 years, ensuring any future spare parts ordered fit with micron-level precision.
Q: Can one mold base handle different preform weights or neck finishes?
A: The mold base configuration and cavity pitch are fixed. However, due to our service-oriented modular construction, you can change the preform weight (by swapping core/cavity inserts of different lengths) or the neck finish (by swapping interchangeable neck rings), provided the total dimensions remain within the engineering boundary of the mold platform.
Q: What kind of after-sales technical support do you provide for international buyers?
A: We provide complete technical clarity to reduce localized deployment risks: detailed English electrical wiring diagrams, cooling circuit layouts, and step-by-step FAT testing parameter logs. In case of unexpected production issues, our engineering team offers remote video technical support within 24 hours to guide your team through troubleshooting.
Q: What are your standard payment and quality verification terms?
A: Our typical commercial milestone workflow is 30% to 40% T/T down payment to initiate design freeze and material procurement, with the remaining balance due after successful Factory Acceptance Testing (FAT). We provide comprehensive testing videos, sample dimensions reports, and cavity balance data prior to final balance payment and shipment dispatch.
