Changzhou Hongxinyutai Precision Mold Co., Ltd. (founded in 2017) brings you a High-Precision Multi-Cavity PET Mold engineered for demanding mass production. Leveraging advanced +GF+ milling and Sodick EDM technology, combined with premium 718 steel, this mold delivers a reliable shot life of 2 million cycles. Designed for PET preform applications, it meets the strict IATF 16949 quality standard, ensuring consistency and durability for global clients across North America, Europe, Southeast Asia, and beyond.
Our mold is the result of over six years of specialized experience in precision mold making. With a factory spanning 1,000–3,000 sqm and a team of 51–100 skilled professionals, we have the capacity to deliver molds that maximize your production efficiency and minimize downtime. Below, we detail the key features, technical specifications, and benefits that set this PET mold apart.
Key Features & Technical Specifications
- Material Excellence: Constructed from 718 steel (comparable to 1.2738) with superior resistance to wear, corrosion, and high-temperature stress. Ideal for mass production of PET preforms, providing long-term dimensional stability.
- Precision Machining: Utilize +GF+ (GF Machining Solutions) high-speed milling for complex cavity geometries and Sodick EDM for micro-fine details, achieving a surface finish of Ra 0.2 µm or better.
- Multi-Cavity Design: Available in customizable cavity configurations (e.g., 16, 32, 48, 64, or more) to match your injection molding machine and output requirements. Each cavity is individually calibrated for balanced filling.
- 2 Million Shots Life: Heat-treated and stress-relieved steel, combined with optimized cooling circuits, ensures consistent performance up to 2,000,000 cycles before routine maintenance, reducing total cost of ownership.
- IATF 16949 Certification: Our manufacturing process meets the automotive-grade quality management system, ensuring traceability, process control, and defect prevention. This certification is especially valuable for clients in automotive supply chains or high-volume packaging.
- Cooling Optimization: Conformal cooling channels (designed via CFD simulation) reduce cycle time by up to 20% compared to standard designs, while maintaining uniform temperature across all cavities.
- User-Friendly Maintenance: Quick-change mechanism for wear components (e.g., neck rings, inserts) minimizes downtime. Each mold is supplied with a detailed maintenance manual.

| Cavity Count | Custom (e.g., 16 to 96 cavities) |
| Certification | IATF 16949 |
| Surface Finish | Ra ≤ 0.2 µm (mirror finish optional) |
| Cycle Time | Depends on preform weight; typically 10–15 sec |
| Mold Base | Customizable (DME, HASCO, or standard) |
Customer Benefits
- Higher Output: Multi-cavity design and faster cooling enable higher production rates, reducing per-part cost and boosting your ROI.
- Consistent Quality: Precision machining ensures each preform meets tight weight and dimensional tolerances (±0.02 mm), critical for downstream stretch blow molding.
- Lower Maintenance: 718 steel combined with 2M shot life means fewer stoppages for mold refurbishment. Our molds typically require only standard cleaning after 500,000 shots.
- Global Compatibility: Suitable for various PET injection molding machines (e.g., Husky, Netstal, Krones) with no adapters needed. We customize the nozzle radius and stack height per your machine.
- Process Support: Our experienced team offers trial runs and technical guidance to optimize your injection parameters for PET material (intrinsic viscosity 0.72–0.84 dl/g).

Frequently Asked Questions
Q1: What is the typical delivery time for this PET mold?
A: Standard lead time is 30–45 working days from design approval. Rush orders (20–25 days) are possible based on capacity availability.
Q2: Can I customize the cavity count to match my existing machine?
A: Absolutely. We design the mold according to your machine's tie bar spacing, shot capacity, and clamp force. Cavity count can be any number within practical limits (e.g., 32, 48, 64, 72).
Q3: Does this mold work with recycled PET (rPET) material?
A: Yes, the 718 steel and hard coating options (e.g., DLC or nitriding) enhance wear resistance when processing rPET, which may contain more abrasive contaminants. We recommend discussing your specific rPET grade for optimal results.
Q4: What is the warranty period and what does it cover?
A: We offer a 12-month warranty from shipment, covering material defects and workmanship issues. Wear parts (e.g., neck rings, slide inserts) are excluded but can be supplied as spare parts.
Q5: How do you ensure the mold meets IATF 16949 requirements?
A: Our manufacturing process follows IATF 16949 procedures: from design FMEA, PPAP submissions to control plan documentation. We provide full quality documentation upon request.
Q6: Can I receive a sample preform for testing before mass production?
A: Yes, we can produce a small batch of preforms using your mold for your line validation. Sample testing cost is negotiable and will be deducted from the final order.
Q7: What is the recommended injection pressure range?
A: We recommend 800–1400 bar injection pressure for typical PET. Our mold is designed to withstand up to 2000 bar safety margin.
Q8: Do you have any references from clients in the automotive sector?
A: Yes, we have supplied molds to Tier-1 automotive interior part manufacturers. References can be provided under NDA.
