At Changzhou Hongxinyutai Precision Mold Co., Ltd., we specialize in manufacturing high-quality extrusion blow molds for PE bottles. As a dedicated manufacturer established in 2017, our 1,000–3,000 m² facility houses 51–100 skilled professionals, enabling us to deliver precision molds that meet rigorous production demands. Our OEM PE bottle extrusion blow molding solution is engineered with a 7075 aluminum framework and S136 steel cavity inserts, combined with a 4+4 cavity configuration and an advanced robotic arm system. This mold is TS16969 certified, ensuring consistent quality and process control for your bottle production lines.
The 7075 aluminum alloy provides excellent strength-to-weight ratio and thermal conductivity, while the S136 stainless steel inserts offer superior corrosion resistance and wear life. With 4+4 cavities, our mold achieves high output per cycle, significantly boosting your production efficiency. The integrated robotic arm automates part handling and removal, reducing manual labor and cycle time. Whether you need standard PE bottles or custom-shaped containers, this mold is designed for reliable, long-term performance.
Key Features & Technical Specifications
- Superior Material Combination: 7075 aluminum frame ensures lightweight rigidity and rapid heat dissipation; S136 steel inserts provide hardness (HRC 48–52) and excellent resistance to acidic cleaning agents.
- High Cavity Efficiency: 4+4 cavities (4 cavities on each side, total 8) allow for simultaneous production of multiple bottles, increasing output by up to 80% compared to traditional 2-cavity molds.
- Robotic Arm Automation: The mold is compatible with a servo-driven robotic arm for automatic extraction, trimming, and stacking, minimizing operator intervention and reducing defects.
- TS16969 Certified Quality System: Our production follows IATF 16949-equivalent standards (TS16969) to ensure traceability, process control, and continuous improvement – critical for automotive and packaging industries.
- Customizable Design: We accept OEM specifications for bottle shape, neck finish, wall thickness distribution, and weight. Optional features include hot runner systems, venting inserts, and specialized cooling channels.

Frequently Asked Questions (FAQ)
1. What is the lead time for this mold?
Typically 35–45 working days after design approval and deposit. Custom molds may require additional time.
2. Can the mold be adapted for other plastic materials besides PE?
This mold is optimized for PE, but with minor adjustments (e.g., cooling and venting) it can work with PP, PETG, or other extrusion blowable materials.
3. What maintenance is needed for the 7075/S136 mold?
Regular cleaning using mild solvents, periodic lubrication of moving parts, and inspection of cavity surfaces every 500,000 cycles are recommended.
4. Do you provide mold design support?
Yes, our in-house engineering team can design the mold based on your bottle samples or 3D models. We offer DFM analysis free of charge for new orders.
5. Is the robotic arm included with the mold?
The mold includes an interface plate and mounting provisions for a standard robotic arm. The arm itself can be supplied as an optional accessory at extra cost.
6. How do you ensure the mold meets TS16969 standards?
We follow APQP and PPAP processes, document all inspections, and conduct capability studies (Cp, Cpk) for critical dimensions. Each mold is tested before shipment.
7. What is your warranty policy?
We offer a 12-month warranty covering defects in materials and workmanship under normal operating conditions. Extended warranty is available.
8. Can I visit your factory in Changzhou?
Absolutely. We welcome customer visits to inspect our production processes and discuss project details. Please contact us to schedule.
